    The sole issue presented on this appeal is the meaning of counterfeit substance in
    § 4B1.2(b) of the United States Sentencing Guidelines. Defendant contends that a
    counterfeit substance is a controlled substance that has been mislabeled or misbranded
    fraudulently or without authorization—a definition that appears in a federal statute, 21
    U.S.C. § 802(7). The government counters that it is a noncontrolled substance that is
    passed off as a controlled substance. Joining the five other circuits that have opined on
    the subject, we agree with the government.
    Under USSG § 2K2.1(a)(2) the base offense level for a defendant convicted of a
    firearm offense is 24 if the offense was committed “subsequent to sustaining at least two
    felony convictions of either a crime of violence or controlled substance offense.” The
    offense level is 20 if the defendant had a conviction of only one such offense. See 
    id. § 2K2.1(a)(4).
    These provisions adopt the meaning of controlled substance offense in
    USSG § 4B1.2(b). See USSG § 2K2.1(a), App. n.1. That definition is as follows:
    The term “controlled substance offense” means an offense
    under federal or state law, punishable by imprisonment for a
    term exceeding one year, that prohibits the manufacture,
    import, export, distribution, or dispensing of a controlled
    substance (or a counterfeit substance) or the possession of a
    controlled substance (or a counterfeit substance) with intent
    to manufacture, import, export, distribute, or dispense.
    USSG § 4B1.2(b) (emphasis added). The guidelines do not define counterfeit substance
    for the purposes of this provision.
    Defendant Donald Ray Thomas pleaded guilty in the United States District Court
    for the District of Colorado to possession of a firearm by a convicted felon. See 18
    U.S.C. § 922(g)(1). On appeal he does not challenge the validity of his plea; but as
    permitted by his plea agreement with the government, he raises one challenge with
    respect to his sentence. Because it is undisputed that he had a prior felony conviction for
    a crime of violence (robbery), his base offense level was at least 20. Whether it was 20
    2
    or 24 depended on the characterization of his 2014 Colorado conviction of distribution of
    an “imitation controlled substance” under Colo. Rev. Stat. § 18-18-422(1)(a). Colorado
    defines an imitation controlled substance as:
    a substance that is not the controlled substance that it is purported to
    be but which, by appearance, including color, shape, size, and
    markings, by representations made, and by consideration of all
    relevant factors as set forth in section 18-18-421, would lead a
    reasonable person to believe that the substance is the controlled
    substance that it is purported to be.
    Colo. Rev. Stat. § 18-18-420(3). Defendant challenges the district court’s ruling that his
    conviction involved a “counterfeit substance” and therefore was a “controlled substance
    offense” under USSG § 2K2.1(a). Exercising jurisdiction under 18 U.S.C. § 3742(a) and
    28 U.S.C. § 1291, we reject this challenge and affirm Defendant’s sentence.
    I.     DISCUSSION
    “Ultimately, our task in interpreting the Guidelines is to determine the intent of
    the Sentencing Commission.” United States v. Rivera-Oros, 
    590 F.3d 1123
    , 1129 (10th
    Cir. 2009). We perform this task by applying traditional techniques of statutory
    construction. See United States v. Archuleta, 
    865 F.3d 1280
    , 1287 (10th Cir. 2017)
    (when a term “is not defined in the Guidelines, we must rely on the accepted rules of
    statutory construction in defining the term”).
    As a general rule, we interpret a word or phrase in a statute or the guidelines in
    accordance with its ordinary, everyday meaning. See United States v. Marrufo, 
    661 F.3d 1204
    , 1207 (10th Cir. 2011) (“When a term is not defined in the Guidelines, we give it its
    plain meaning.”); Antonin Scalia & Brian A. Garner, Reading Law: The Interpretation of
    3
    Legal Texts, § 6 (“Ordinary-Meaning Canon”) (2012) (“Reading Law”). The definition
    of counterfeit in the most authoritative legal dictionary is: “Made to look genuine in an
    effort to deceive; produced by fakery, esp. with an intent to defraud.” Black’s Law
    Dictionary 427 (10th ed. 2014). This is in keeping with the definitions in leading
    dictionaries for general use. See New Oxford American Dictionary 387 (2d ed. 2005)
    (“[M]ade in exact imitation of something valuable or important with the intention to
    deceive or defraud.”); Webster’s Third New International Dictionary 519 (2002)
    (“[M]ade in fraudulent imitation: produced with intent to deceive.”). Thus, a substance
    that is not in fact a controlled substance but is passed off as such is commonly referred to
    as a counterfeit controlled substance. See, e.g., Franklin v. Bradshaw, 
    545 F.3d 409
    , 412
    (6th Cir. 2008) (“Hennig realized that they had been given counterfeit cocaine commonly
    referred to as ‘fleece.’”); United States v. Martinez, 
    520 F.3d 749
    , 751 (7th Cir. 2008)
    (“The [drug] agents replaced the cocaine with 100 kilograms of counterfeit cocaine.”);
    United States v. Sampson, 
    140 F.3d 585
    , 588 (4th Cir. 1998) (two co-conspirators
    “testified that . . . they sold ‘flex’ (counterfeit cocaine) to unsuspecting purchasers.”).
    The government urges us to use the plain-English definition of counterfeit and construe
    counterfeit substance as a substance made in imitation of a controlled substance with
    intent to deceive.
    Defendant does not contend that if we apply the common meaning of counterfeit
    substance, he could nevertheless prevail. He argues, however, that we should adopt a
    narrower meaning. He asserts that when determining the meaning of an undefined
    offense used in the guidelines, courts have not given the term its ordinary English
    4
    meaning but have instead looked to federal statutes, state laws, model codes, treatises,
    and dictionaries to determine the “generic, contemporary meaning” of the offense. Aplt.
    Br. at 11; see United States v. Martinez-Cruz, 
    836 F.3d 1305
    , 1309 (10th Cir. 2016) (“To
    determine the generic, contemporary meaning of a crime enumerated in the Guidelines,
    the court begins by looking to the federal statute under which the defendant was
    previously convicted” and “also examines . . . the definitions of the crime in a majority of
    the States’ criminal codes, as well as prominent secondary sources, such as criminal law
    treatises and the Model Penal Code.” (brackets and internal quotation marks omitted));
    
    Rivera-Oros, 590 F.3d at 1126-27
    (“We look to a wide range of sources to determine the
    generic meaning of an enumerated offense, including federal and state statutes, the Model
    Penal Code, dictionaries, and treatises.”). Accordingly, in his view, we must adopt the
    definition of counterfeit substance commonly used in those sources.
    We agree with Defendant that the statutory definitions of the term counterfeit
    substance most often refer to controlled substances that are fraudulently or falsely
    labeled. For example, and most notably, the federal Controlled Substances Act states the
    following:
    The term ‘counterfeit substance’ means a controlled substance
    which, or the container or labeling of which, without authorization,
    bears the trademark, trade name, or other identifying mark, imprint,
    number, or device, or any likeness thereof, of a manufacturer,
    distributor, or dispenser other than the person or persons who in fact
    manufactured, distributed, or dispensed such substance and which
    thereby falsely purports or is represented to be the product of, or to
    have been distributed by, such other manufacturer, distributor, or
    dispenser.
    5
    21 U.S.C. § 802(7). The term appears in 21 U.S.C. § 841(a), which provides:
    (a) Unlawful acts
    Except as authorized by this subchapter, it shall be unlawful for
    any person knowingly or intentionally—
    (1) to manufacture, distribute, or dispense, or possess with intent
    to manufacture, distribute, or dispense, a controlled substance; or
    (2) to create, distribute, or dispense, or possess with intent to
    distribute or dispense, a counterfeit substance.
    Paragraph (1) in general prohibits dealing in controlled substances. The “Except as
    authorized” language at the beginning of subsection (a) is necessary, however, because
    some controlled substances serve useful purposes and can lawfully be manufactured,
    distributed, dispensed, or possessed, although they must still be regulated to protect
    consumers and prevent misuse. Effective regulation of such substances requires that they
    be properly labeled—that is, that they not be what are called “counterfeit substances” in
    the statute. Paragraph 2 prohibits trading in such counterfeits. For example, even when a
    person is authorized to manufacture a controlled substance, that person is prohibited from
    creating a counterfeit substance by mislabeling the controlled substance. Cf. United
    States v. Khoury, 
    901 F.2d 948
    , 965 (11th Cir. 1990) (“At a minimum, to prove a
    conspiracy to violate section 841(a)(2) . . . the government must provide some evidence
    that the conspirators planned to place on the substance or its container a trademark, trade
    name, or other identifying mark of a manufacturer other than the persons actually
    manufacturing the substance.”)
    The Uniform Controlled Substances Act uses the term counterfeit substances in
    the same way:
    6
    Counterfeit Substances Prohibited; Penalty.
    (a) A person may not knowingly or intentionally manufacture
    or deliver, or possess with intent to manufacture or deliver,
    a controlled substance that, or the container or labeling of
    which, without authorization, bears the trademark, trade
    name, or other identifying mark, imprint, number, or
    device, or a likeness thereof, of a manufacturer, distributor,
    or dispenser, other than the person who manufactured,
    distributed, or dispensed the substance.
    Unif. Controlled Substances Act § 404 (1995). And the government does not dispute
    Defendant’s assertion that the laws of 36 states and the District of Columbia similarly
    define counterfeit substance, although it points to eight states that have adopted the
    meaning of counterfeit substance that it urges in this court.
    The essence of Defendant’s position is that when dealing with a technical or
    specialized subject, we should understand terms in their technical or specialized meaning.
    As a general rule, we would agree with that proposition. But that proposition cannot
    override common sense. In Johnson v. United States, 
    599 U.S. 133
    , 138 (2010), the
    Supreme Court had to resolve the meaning in the Armed Career Criminal Act (ACCA),
    18 U.S.C. § 924(e), of the noun force, which “has a number of meanings.” The specific
    question was whether the Florida offense of battery constituted a “violent felony” under
    the Act (and so could be used to enhance the defendant’s sentence). That depended on
    whether the requirement of “force” in the ACCA could be satisfied by “even the slightest
    offensive touching,” which was all the force necessary to establish the common-law
    crime of battery (and battery under Florida law). See 
    id. at 139.
    The Court refused to
    adopt the common-law meaning of the term force, finding it incongruous as part of the
    7
    definition of the term violent felony, particularly because common-law battery was a
    misdemeanor rather than a felony. See 
    id. at 139–42.
    It explained: “[W]e do not assume
    that a statutory word is used as a term of art where that meaning does not fit. Ultimately,
    context determines meaning, and we do not force term-of-art definitions into contexts
    where they plainly do not fit and produce nonsense.” 
    Id. at 139–41
    (citation and internal
    quotation marks omitted).
    Similar reasoning requires rejection of Defendant’s argument. Application of his
    definition of counterfeit substance in USSG § 4B1.2(b) adds no substantive content to the
    guidelines definition of controlled substance offense. For convenience we repeat that
    provision:
    The term “controlled substance offense” means an offense
    under federal or state law, punishable by imprisonment for a
    term exceeding one year, that prohibits the manufacture,
    import, export, distribution, or dispensing of a controlled
    substance (or a counterfeit substance) or the possession of a
    controlled substance (or a counterfeit substance) with intent
    to manufacture, import, export, distribute, or dispense.
    USSG § 4B1.2(b) (emphasis added). Under the statutory definition that Defendant would
    adopt (“The term ‘counterfeit substance’ means a controlled substance which [is
    mislabeled].” 21 U.S.C. § 802(7)), every counterfeit substance is already a controlled
    substance; a counterfeit substance is simply a controlled substance that is mislabeled to
    conceal its origin. The parenthetical “(or a counterfeit substance)” therefore would not
    include any item beyond those clearly encompassed by the term controlled substance,
    which immediately precedes the parenthetical. Statutes that regulate, say, the distribution
    of counterfeit substances (using Defendant’s definition) are simply a subset of statutes
    8
    that regulate the distribution of controlled substances. We follow our precedent stating
    that “we should interpret statutory provisions and the guidelines in a way which gives
    meaning and effect to each part of the statutory or guideline scheme.” United States v.
    Acosta-Olivas, 
    71 F.3d 375
    , 379 (10th Cir. 1995); see Reading Law, § 26, Surplusage
    Canon, at 174 (“If possible, every word and every provision is to be given effect (verba
    cum effectu sunt accipienda). None should be ignored. None should needlessly be given
    an interpretation that causes it to duplicate another provision or to have no
    consequence.”).
    To avoid the surplusage canon, Defendant notes that the term counterfeit
    substance appears in § 4B1.2(b) only within a parenthetical and contends that “any
    redundancy . . . is therefore of little consequence.” Aplt. Br. at 17. He relies on
    Chickasaw Nation v. United States, 
    534 U.S. 84
    , 88 (2001), in which Indian tribes
    claimed that a parenthetical statutory cross-reference in the Indian Gaming Regulatory
    Act exempted gambling operations from excise and occupational taxes. The Supreme
    Court quoted the following from a circuit-court opinion: “A parenthetical is, after all, a
    parenthetical, and cannot be used to overcome the operative terms of the statute.” 
    Id. at 95
    (internal quotation marks omitted). (The quotation, appropriately enough, was in a
    parenthetical to the citation to the circuit-court opinion. We decline, in this parenthetical,
    to engage in a philosophical discussion about whether a parenthetical can be authority for
    the proposition that parentheticals are not authoritative.) But the Chickasaw Nation
    Court did not say that parentheticals are necessarily surplusage. On the contrary, it took
    the parenthetical cross-reference in the statute very seriously. Indeed, it was the central
    9
    subject of the Court’s decision. The Court determined that it was required to treat the
    relevant language as surplusage not because it was contained in a parenthetical, but
    because “the language outside the parenthetical is unambiguous” and the Court could not
    “give the [parenthetical] reference independent operative effect without seriously
    rewriting the language of the rest of the statute.” 
    Id. at 89;
    see 
    id. (“We agree
    with the
    Tribes that rejecting their argument reduces the [statutory reference in the parenthetical]
    to surplusage. Nonetheless, we can find no other reasonable reading of the statute.”) We
    therefore conclude from Chickasaw Nation that we should try to give substantive effect
    to language in a parenthetical. And here, in contrast to Chickasaw Nation, giving the
    parenthetical in the guideline its common meaning adds eminently reasonable content to
    the guideline (by expanding the relevant offenses to encompass those involving fake
    controlled substances). We also observe that putting “or a counterfeit substance” in a
    parenthetical, rather than simply setting it off with commas, is more likely to have been
    for purposes of readability than to signify unimportance (as suggested by the dissent).
    There were already 10 commas in the sentence defining controlled substance offense.
    The reader may wish to try replacing the parentheses by commas and see how easy it
    would be to read the definitional sentence.1
    1
    Replacing the parentheses by commas in the guideline would result in the following
    awkward language, in which the conjunction or sometimes joins substances and
    sometimes joins actions, thereby discombobulating the reader:
    The term “controlled substance offense” means an
    offense under federal or state law, punishable by
    imprisonment for a term exceeding one year, that prohibits
    the manufacture, import, export, distribution, or dispensing of
    10
    The dissent suggests that the “(or counterfeit substance)” parenthetical serves the
    purpose of clarification—making clear that counterfeit substances (as defined by the
    dissent) are among the controlled substances covered by the guideline. But if that were
    the intent, the Sentencing Commission would have used the word including rather than
    the word or. The Sentencing Commission appears to have followed a consistent practice
    that distinguishes (in accord with common usage) between parentheticals beginning with
    the word including and parentheticals beginning with the word or when the parenthetical
    appears after a term in a guideline. Parentheticals using the word including are meant to
    clarify the guideline; those with the word or are meant to expand the meaning. When it
    uses the word including, it is emphasizing that the term as used in the guideline is not
    excluding a particular subset of what is encompassed by the usual meaning of the term.
    For example, USSG § 2B3.2 cmt. n.1 speaks of “transportation systems and services
    (including highways, mass transit, airlines, and airports”). The words in the parenthetical
    are generally considered examples (subsets) of the terms before the parenthetical. We
    include in a footnote the occasions of this use of including in the guidelines.2 In
    a controlled substance, or a counterfeit substance, or the
    possession of a controlled substance, or a counterfeit
    substance, with intent to manufacture, import, export,
    distribute, or dispense.

    contrast, when the Commission inserts a parenthetical beginning with the word or after a
    term in the guidelines, it is expanding the scope of the guideline to include things that
    would generally not be considered subsets of the term in its common meaning. For
    example, USSG § 2B1.1 comment n.10(C) speaks of “the defendant (or a person for
    whose conduct the defendant is accountable)” and comment n.10(D) speaks of “name (or
    other identifying information).” We include in a footnote other examples of this use of
    the word or in guidelines parentheticals.3 Given this common usage and the practice of
    the Sentencing Commission, we can infer that if the Sentencing Commission intended the
    “or a counterfeit substance” parenthetical in § 4B1.2(b) to refer to those controlled
    substances defined as counterfeit substances in 21 U.S.C. § 802(7)—which are a subset
    of controlled substances—it would have said “including a counterfeit substance.” That
    would have made clear that when § 4B1.2(b) spoke of controlled substances, it was
    including those controlled substances defined as counterfeit substances. But instead the
    Commission said “or a counterfeit substance,” and the use of the word or was signaling
    § 2D1.12 cmt. n.3, § 2E2.1(b)(1), § 2G2.5(b)(2), § 2H3.1 cmt. n.1, § 2H3.1 cmt. n.4, §

    12
    that the Commission was including substances that are not controlled substances. This is
    substantial support for our reading of the guideline.
    It should also be noted that the definition of controlled substance offense in
    § 4B1.2(b) does not include the word creation along with the prohibited acts
    “manufacture, import, export, distribution, or dispensing,” even though creation is the
    prohibited act unique to counterfeit substances, see 21 U.S.C. § 841(a)(2); 
    Khoury, 901 F.2d at 965
    . This is a peculiar, and confusing, omission if the Sentencing Commission’s
    focus in including the “or a counterfeit substance” parenthetical had been to make sure
    that the enhancement of the firearm-offense base offense level under § 2K2.1(a)(2) for
    prior drug convictions would encompass prior convictions under § 841(a)(2) (the federal
    counterfeit-substance provision) and similar state laws.
    A further indication, if any is needed, that § 4B1.2(b) was not referencing the
    statutory definition of counterfeit substance is that the Sentencing Commission did not
    include a statutory reference in the guideline. Not only are such cross-references
    common in the guidelines, see, e.g., United States v. Mills, 
    485 F.3d 219
    , 223 (4th Cir.
    2007) (citing numerous statutory cross-references in §§ 4B1.2 and 2K2.1), but of
    particular note, the Commission has even cross-referenced the statutory definition of
    counterfeit substance in a different guideline. Application note 4 to USSG § 2D1.1 (the
    guideline section used to compute the offense level for drug offenses) states: “The statute
    and guideline also apply to ‘counterfeit’ substances, which are defined in 21 U.S.C. § 802
    to mean controlled substances that are falsely labeled so as to appear to have been
    legitimately manufactured or distributed.” If the Sentencing Commission also intended
    13
    to use that statutory definition in § 4B1.2, it would be remarkable to omit the cross-
    reference there. Cf. United States v. Lucero, 
    747 F.3d 1242
    , 1249 (10th Cir. 2014) (“It is
    a well-settled principle of statutory construction that when Congress (or, as here, the
    Sentencing Commission) includes particular language in one section of a statute or
    Guideline, it is generally presumed that Congress acts intentionally and purposely in the
    disparate inclusion or exclusion.” (internal quotation marks omitted)). The cross
    reference to the statutory definition appeared in the original version of § 2D1.1 in 1987.
    See USSG § 2D1.1 cmt. n.2, at 2.40 (1987). The term counterfeit substance first
    appeared in § 4B1.2 as a result of Amendment 268 two years later in 1989. See U.S.
    Sentencing Guidelines Manual app. C, vol. I, Amend. 268 at 131–33 (2003). It is not as
    if it had never occurred to the Sentencing Commission to add the statutory definition as a
    cross reference. The omission of the cross-reference in § 4B1.2 only two years after it
    was added in § 2D1.1 appears to have been informed and intentional.
    Defendant also argues that the history of § 4B1.2 supports his position. He
    contends that the language of the guideline before it was revised in 1989 clearly conveys
    the meaning he now advocates.4 We do not think the earlier language was all that clear.
    But in any event, the Sentencing Commission explained that the purpose of its 1989
    4
    The pre-1989 guideline read: “The term ‘controlled substance offense’ as used in this
    provision means an offense identified in 21 U.S.C. §§ 841, 845(b), 856, 952(a), 955,
    955(a), 959; and similar offenses.” USSG § 4B1.2(2), at 4.11 (1988). An application
    note added: “‘Controlled substance offense’ includes any federal or state offense that is
    substantially similar to any of those listed in subsection (2) of the guideline. These
    offenses include manufacturing, importing, distributing, dispensing, or possessing with
    intent to manufacture, import, distribute or dispense, a controlled substance (or a
    counterfeit substance).” 
    Id. cmt. n.2,
    at 4.12.
    14
    amendment was “to clarify the definitions of crime of violence and controlled substance
    offense used in this guideline.” U.S. Sentencing Guidelines Manual app. C, vol. I,
    Amend. 268 at 132–33 (2003). In that light, it would make little sense to say that the
    present guideline is clarified by looking at the earlier version. If, as suggested by
    Defendant, the earlier version clearly supported his position, the change in language
    would imply that the Commission was not comfortable with that position.
    We should also respond to a comment repeated several times in the dissent,
    although it has no basis in any principle of statutory interpretation. The dissent suggests
    that we should not adopt a definition contrary to a definition that “was promulgated by
    elected legislatures.” Dissent at 5. The implication is that when Congress has defined a
    term (as it has with counterfeit substance), we are violating the will of the people by
    adopting another definition. There might be some force to the argument if Congress had
    stated in a statute that its statutory definition of counterfeit substance was to apply
    throughout federal law, or at least to the sentencing guidelines. But the definitions in 21
    U.S.C. § 802 are simply for words “[a]s used in this subchapter,” meaning 21 U.S.C.
    §§ 801–904. That is the full extent of Congress’ statutory command. Congress has not
    made any attempt to tell the Sentencing Commission how it must use the term counterfeit
    substance in its guidelines. It is worth noting that even when Congress has explicitly
    stated that a definition is to apply to a certain portion of the United States Code, the
    Supreme Court has repeatedly ignored that command when the context otherwise requires.
    See, e.g., Util. Air Regulatory Grp. v. EPA, 
    573 U.S. 302
    , 316 (2014); N.W. Austin Mun.
    Util. Dist. No. One v. Holder, 
    557 U.S. 193
    , 206 (2009); Philco Aviation, Inc. v. Shacket,
    15
    
    462 U.S. 406
    , 409 (1983); Lawson v. Suwannee Fruit & S.S. Co., 
    336 U.S. 198
    , 201
    (1949).
    And as recently stated by Justice Ginsburg in Yates v. United States, 
    135 S. Ct. 1074
    , 1082 (2015) (opinion of Ginsburg, J.), “We have several times affirmed that
    identical language may convey varying content when used in different statutes,
    sometimes even in different provisions of the same statute.” The Supreme Court has
    even had occasion to reject the suggestion that a term in the Controlled Substances Act
    must be given the same definition as it has under the guidelines. See DePierre v. United
    States, 
    564 U.S. 70
    , 88 (2011) (“[W]e reject DePierre’s suggestion that the term ‘cocaine
    base’ as used in [21 U.S.C. § 841(b)(1)(A)(iii), (B)(iii)] must be given the same definition
    as it has under the Guidelines.”). In that case the defendant wished to benefit from the
    guidelines definition, which was narrower than the definition of the statutory term
    adopted by the Court. The Court denied the defendant his wish, and it never suggested
    that the Sentencing Commission had to use the word the same way that the statute did.
    Thus, standard tools of statutory interpretation all point to the government’s
    construction of the guidelines definition of controlled substance offense. This should
    suffice to affirm the sentence imposed by the district court.
    But there is more. Institutional considerations also argue in favor of that result.
    At least five other circuits have reached the same conclusion as we do here. See United
    States v. Hudson, 
    618 F.3d 700
    , 704 (7th Cir. 2010); United States v. Mills, 
    485 F.3d 219
    ,
    225 (4th Cir. 2007); United States v. Robertson, 
    474 F.3d 538
    , 541 (8th Cir. 2007);
    United States v. Crittenden, 
    372 F.3d 706
    , 709 (5th Cir. 2004); United States v. James,
    16
    712 F. App’x 838, 840 (11th Cir. 2017) (citing United States v. Frazier, 
    89 F.3d 1501
    ,
    1505 (11th Cir. 1996)); United States v. Smith, 156 F. App’x 154, 155–56 (11th Cir.
    2005) (same). None have agreed with Defendant’s position.
    We should not create a circuit split merely because we think the contrary
    arguments are marginally better. A number of circuits have stated that only a
    “compelling” or “strong” reason can justify creation of a circuit split. See Padilla-
    Ramirez v. Bible, 
    882 F.3d 826
    , 836 (9th Cir. 2017), cert. denied, 
    139 S. Ct. 411
    (2018)
    (“As a general rule, we decline to create a circuit split unless there is a compelling reason
    to do so.” (internal quotation marks omitted)); United States v. Nesmith, 
    866 F.3d 677
    ,
    680 (5th Cir. 2017) (adopting the same position as other circuits “[b]ecause [the
    appellant] has not provided a compelling reason to create a circuit split.”); Janese v. Fay,
    
    692 F.3d 221
    , 227 (2d Cir. 2012) (“[I]n the absence of compelling reasons to the
    contrary, maintaining a circuit split . . . is inadvisable.”); Alternative Sys. Concepts, Inc.
    v. Synopsys, Inc., 
    374 F.3d 23
    , 31 (1st Cir. 2004) (“A court of appeals should always be
    reluctant to create a circuit split without a compelling reason, and none exists here.”);
    Wagner v. PennWest Farm Credit, ACA, 
    109 F.3d 909
    , 912 (3d Cir. 1997) (“In light
    of such an array of precedent [from other circuits], we would require a compelling basis
    to hold otherwise before effecting a circuit split.”); Wash. Energy Co. v. United States, 
    94 F.3d 1557
    , 1561 (Fed. Cir. 1996) (“As a general matter, we do not create conflicts among
    the circuits without strong cause. We adhere to this view because federal law (unlike
    state law) is supposed to be unitary.” (citation and internal quotation marks omitted));
    Mayer v. Spanel Int’l Ltd., 
    51 F.3d 670
    , 675 (7th Cir. 1995) (“We do not create conflicts
    17
    among the circuits without strong cause.”), abrogated on other grounds by Field v. Mans,
    
    516 U.S. 59
    , 74–75 (1995). This court has simply expressed reluctance to create a circuit
    split, without describing the threshold necessary to overcome the reluctance. See United
    States v. Smith, 
    815 F.3d 671
    , 677 (10th Cir. 2016) (“[O]ur reading . . . avoids the
    unnecessary creation of a circuit split.”); Brunswick Corp. v. Spinit Reel Co., 
    832 F.2d 513
    , 528 (10th Cir. 1987) (“[W]e are not inclined to create a split in the circuit courts.”);
    see also United States v. Games-Perez, 
    695 F.3d 1104
    , 1115 (10th Cir. 2012) (Murphy,
    J., concurring in denial of rehearing en banc) (“[T]he circuits have historically been loath
    to create a split where none exists. . . . [As one circuit put it,] ‘Absent a strong reason to
    do so, we will not create a direct conflict with other circuits.’” (citations omitted)); 
    id. at 1123
    n.7 (Gorsuch, J., dissenting from denial of rehearing en banc) (“[W]hile the
    concurrence quotes cases from other circuits counseling against creating a circuit split
    ‘absent a strong reason to do so,’ inconsistency with an unambiguous statutory direction
    from Congress surely qualifies as just such a strong reason.” (citation omitted)). But at
    least there must be a “sound reason” to go against the tide. Anderson v. Private Capital
    Grp., 549 F. App’x 715, 718 (10th Cir. 2013). As one member of this court has
    explained, “The avoidance of unnecessary circuit splits furthers the legitimacy of the
    judiciary and reduces friction flowing from the application of different rules to similarly
    situated individuals based solely on their geographic location.” 
    Games-Perez, 695 F.3d at 1115
    (Murphy, J., concurring in denial of rehearing en banc). And the greater the
    number of circuits that are aligned together, the more an appropriate judicial modesty
    should make us reluctant to reject that uniform judgment. Although Defendant’s
    18
    argument is hardly frivolous, we do not think it sufficiently persuasive to overcome that
    reluctance.
    Supporting our view that there is not a good reason, much less a strong or
    compelling one, to split from the other circuits on this issue is the inaction of the
    Sentencing Commission. The Commission has declined to amend the guidelines
    definition of controlled substance offense to counter the unanimous circuit opinions (say,
    by adding a simple cross-reference to the federal statutory definition of counterfeit
    substance) during the 15 years since the first published circuit opinion adopting our
    position, even after two panel dissents, see 
    Crittenden, 372 F.3d at 710
    (Dennis, J.,
    concurring in part and dissenting in part); 
    Frazier, 89 F.3d at 1508
    , (Godbold, J.,
    concurring in part and dissenting in part), and the Seventh Circuit’s explicit suggestion
    more than nine years ago that the issue “may be worth the attention of the Sentencing
    Commission.” 
    Hudson, 618 F.3d at 704
    . This court has repeatedly said that the
    Commission’s failure to modify a guideline in response to judicial interpretations of the
    guideline indicates Commission satisfaction with the interpretation. In United States v.
    O’Flanagan, 
    339 F.3d 1229
    , 1231 (10th Cir. 2003), the issue was the propriety of
    applying the cross reference to § 2X1.1 in § 2K2.1 to calculate an offense level under the
    robbery guideline in § 2B3.1. We supported our rejection of the defendant’s argument by
    noting that it was contrary to prior decisions of this court and other circuits and that “the
    Sentencing Commission has not expressed displeasure with the uniform judicial
    interpretation and application of § 2X1.1 in the years following.” 
    Id. at 1235.
    Similarly,
    in United States v. Laughrin, 
    438 F.3d 1245
    , 1248–49 (10th Cir. 2006), we followed an
    19
    interpretation of a guideline subsection by two other circuits, saying: “[E]ven if we
    would have been inclined to disagree with the decisions by our fellow circuits as a matter
    of first impression, their persuasive force has been magnified by the Sentencing
    Commission’s apparent agreement with these decisions,” in that “the Sentencing
    Commission has amended [the applicable guideline] twelve times since [the first of the
    circuit decisions]” without changing the language of the pertinent guideline subsection.
    See also United States v. Rosales-Garcia, 
    667 F.3d 1348
    , 1355 (10th Cir. 2012).
    We recognize that the Supreme Court has held that “Congress’ failure to overturn
    a statutory precedent is [no] reason for this Court to adhere to it.” Patterson v. McLean
    Credit Union, 
    491 U.S. 164
    , 175 n.1 (1989). The Court reasoned that “[i]t is impossible
    to assert with any degree of assurance that congressional failure to act represents
    affirmative congressional approval of the Court’s statutory interpretation. Congress may
    legislate, moreover, only through the passage of a bill which is approved by both Houses
    and signed by the President. Congressional inaction cannot amend a duly enacted
    statute.” 
    Id. (citations and
    internal quotation marks omitted).
    But the Sentencing Commission is not Congress. It is an agency within the
    judicial branch, see 28 U.S.C. § 991(a) (“There is established as an independent
    commission in the judicial branch of the United States a United States Sentencing
    Commission . . . .”), with a unique relationship to the courts. For example, although a
    core responsibility of the Supreme Court is to resolve circuit splits, the Court decided in
    Braxton v. United States, 
    500 U.S. 344
    , 348 (1991), that circuit splits regarding the
    sentencing guidelines are best left to the Sentencing Commission to resolve through
    20
    amendments to the guidelines. The Court began by reiterating its essential role in
    resolving disagreements within the lower courts even though other institutions (Congress
    and agencies) could act to eliminate doubt for the future.
    A principal purpose for which we use our certiorari jurisdiction,
    and the reason we granted certiorari in the present case, is to
    resolve conflicts among the United States courts of appeals and
    state courts concerning the meaning of provisions of federal law.
    With respect to federal law apart from the Constitution, we are
    not the sole body that could eliminate such conflicts, at least as far
    as their continuation into the future is concerned. Obviously,
    Congress itself can eliminate a conflict concerning a statutory
    provision by making a clarifying amendment to the statute, and
    agencies can do the same with respect to regulations. Ordinarily,
    however, we regard the task as initially and primarily ours.
    
    Id. at 347–48.
    But, it continued, “this may not be Congress’ intent with respect to the
    Sentencing Guidelines.” 
    Id. at 348.
    Noting that 28 U.S.C. § 994(o) imposes on the
    Commission the duty “periodically to review and revise” the Guidelines, the Court
    explained: “The Guidelines are of course implemented by the courts, so in charging the
    Commission periodically to review and revise the Guidelines, Congress necessarily
    contemplated that the Commission would periodically review the work of the courts, and
    would make whatever clarifying revisions to the Guidelines conflicting judicial decisions
    might suggest.” 
    Id. at 348
    (brackets and internal quotation marks omitted). The statutory
    grant of this Commission responsibility “alone might induce us to be more restrained and
    circumspect in using our certiorari power as the primary means of resolving such
    conflicts,” id.; but there was more. “In addition to the duty to review and revise the
    Guidelines, Congress has granted the Commission the unusual explicit power to decide
    whether and to what extent its amendments reducing sentences will be given retroactive
    21
    effect, 28 U.S.C. § 994(u).” 
    Id. The Court
    therefore decided to forgo review of the circuit
    conflict, leaving that to an ongoing Commission proceeding on the issue. Since then, the
    Court has continued to leave it to the Commission to resolve circuit conflicts regarding
    interpretation of the guidelines.
    The Commission has repeatedly expressed its proactive stance in clarifying and
    improving the guidelines. See, e.g., United States Sentencing Commission, 2013 Annual
    Report, A-19 (“The Commission closely monitors the sentencing decisions of the federal
    courts to identify areas in which guideline amendments, research, or legislative action
    may be needed.”) Then-Circuit Judge Alito commented on the uniqueness of the
    Commission’s role in an essay reviewing its 1991 Annual Report:
    As a court of appeals judge, I was interested by the Report’s
    laconic statement that many of the amendments the Commission
    promulgated in 1991 were “intended to clarify existing guidelines,
    policy statements, and commentary.” What this statement means
    in part is that the Commission, through the amendment process, is
    now performing with respect to the interpretation of the guidelines
    essentially the same role that the Supreme Court plays with
    respect to the interpretation of other federal laws: resolving circuit
    conflicts and generally keeping the courts of appeals in line. . . .
    As far as I am aware, no other federal agency—in any branch—
    has ever performed a role anything like it.
    Samuel Alito, Reviewing the Sentencing Commission’s 1991 Annual Report, 5 Fed.
    Sent’g Rep. 166, 168 (1992) (footnote omitted, emphasis added).
    The dissent suggests that the Sentencing Commission limits its clarification
    amendments to resolving circuit splits. But that misstates Commission practice. To be
    sure, the Commission does take circuit splits seriously. Among the 53 amendments
    promulgated since 2011, there are 12 that say that some of the changes in the amendment
    22
    are responses to circuit splits. See U.S. Sentencing Guidelines Manual supp. to app. C,
    Amend. 801 at 133–37 (2018); 
    id., Amend. 795
    at 111–12; 
    id., Amend. 794
    at 108– 09;
    
    id., Amend 792
    at 104; 
    id., Amend. 786
    at 76–77; 
    id., Amend. 784
    at 72–73; 
    id., Amend. 780
    at 51– 52; 
    id., Amend. 775
    at 40–41; 
    id., Amend. 774
    at 38–39; 
    id., Amend. 767
    at
    18–19; 
    id., Amend. 766
    at 15–16; 
    id., Amend. 764
    at 10–11. But the Commission, in
    keeping track of what is going on in the courts, does not need to wait for a circuit split.
    In the 53 post-2011 amendments, there are five stating that they are clarifying guidelines
    in response to circuit-court decisions where no split was noted, see 
    id., Amend. 812
    at
    194–95 (2018); 
    id., Amend. 809
    at 189; 
    id., Amend. 803
    at 160–62; Amend. 785 at 73–
    74; 
    id., Amend 762
    at 8; three respond to district-court decisions, see 
    id., Amend. 810
    at
    189; 
    id., Amend. 807
    at 176 (2018); 
    id., Amend. 802
    at 145; and three respond to
    concerns raised by persons outside the judiciary, see 
    id., Amend. 803
    at 159–60 (note that
    another provision of Amendment 803 also separately responds to judicial decisions, as
    cited above); 
    id., Amend. 799
    at 128; 
    id., Amend. 783
    at 70–71. Most pertinent, on at
    least one occasion it did what it has failed to do with respect to the question before us—it
    amended a guideline “to address criticism by the Seventh Circuit regarding potential
    ambiguity in how the [guideline] is currently phrased.” 
    Id., Amend. 803
    at 162; see
    
    Hudson, 618 F.3d at 704
    . The Commission’s role is significantly broader than that of the
    Supreme Court in resolving circuit splits.
    The unique nature of the Sentencing Commission as it relates to the federal courts
    requires a careful examination of whether its inaction in the face of numerous judicial
    interpretations over an extended period of time may be of more consequence than a
    23
    failure of Congress to amend a statute. We think it is. The Commission has adopted 813
    amendments to the guidelines, some of which make numerous changes. Given the
    Commission’s duty and practice of reviewing how the federal courts are applying the
    guidelines, it is clear that the failure to act has not been because of ignorance of circuit
    decisions; and the Commission’s small size and focus on detail would ordinarily make
    inertia or the complexity of the enactment process an unlikely cause of inaction. If, for
    instance, the Commission wished to make clear that the term counterfeit substance in a
    guideline is defined in the federal statute, that wish could be easily fulfilled. Also,
    because of the explicit statutory grant to the Commission of the power to make guidelines
    amendments retroactive, it is the present views of the Commission that are of paramount
    importance. Even if it believes that the courts have correctly captured the original
    meaning of a guidelines provision, it can revise its earlier view and make the “correction”
    retroactive. Or if it believes that the courts have misinterpreted its original guideline but
    it is content with the “new” version, it can leave the misinterpretation undisturbed.
    In this light, we can say with some confidence that the Commission—being fully
    aware of the circuit-court interpretations of counterfeit substance in the guideline, the
    dissents from those decisions, and the suggestion by the Seventh Circuit that the
    Commission address the issue—has not thought that the court decisions present a
    significant problem for the guidelines. That being the case, we see no good reason to
    create a circuit split.
    II.     CONCLUSION
    We AFFIRM Defendant’s sentence.
    24
    17-1405, United States v. Thomas
    MATHESON, Circuit Judge, dissenting:
    Mr. Thomas pled guilty to being a felon in possession of a firearm. He previously
    had been convicted for distribution of an “imitation controlled substance”—fake heroin—
    in violation of Colorado law.1 Because the district court concluded this prior offense was
    for selling a “counterfeit substance,” it held that the state conviction qualified as a
    “controlled substance offense” under United States Sentencing Guidelines (“Guidelines”
    or “U.S.S.G.”) §§ 2K2.1 and 4B1.2(b), and it relied on the state conviction to impose an
    enhanced sentence for the felon-in-possession conviction.
    Mr. Thomas challenges his sentence. Resolution of his appeal turns on choosing
    between two competing definitions of the term “counterfeit substance.” The majority
    affirms Mr. Thomas’s enhanced sentence based on the dictionary definition and common
    meaning of the word “counterfeit.” Maj. Op. at 17. In the drug enforcement context,
    however, the U.S. Congress and most state legislatures define “counterfeit substance”
    more narrowly than the district court’s and majority’s dictionary-based definition.
    Because the Sentencing Commission promulgated Guidelines addressing drug offenses
    1
    Under Colorado law, an “imitation controlled substance” is “a substance that is
    not the controlled substance that it is purported to be but which, by appearance, including
    color, shape, size, and markings, by representations made, and by consideration of all
    relevant factors as set forth in section 18-18-421, would lead a reasonable person to
    believe that the substance is the controlled substance that it is purported to be.” Colo.
    Rev. Stat. Ann. § 18-18-420(3). A separate provision makes it “unlawful for a person to
    manufacture, distribute, or possess with intent to distribute an imitation controlled
    substance.” 
    Id. § 18-18-422(1)(a).
    against that legislative backdrop, we should rely on the predominant legal definition of
    the term. I therefore dissent.
    I. BACKGROUND
    The Sentencing Guidelines increase the sentence for a firearms offense when a
    defendant has previously committed a “crime of violence or a controlled substance
    offense.” U.S.S.G. § 2K2.1(a). If the firearm offense occurred after one such crime, the
    Guidelines set a base offense level at 20. U.S.S.G. § 2K2.1(a)(4). If it occurred
    “subsequent to sustaining at least two felony convictions of either a crime of violence or
    a controlled substance offense,” § 2K2.1(a)(2) provides for a base offense level of 24.
    To define its terms, § 2K2.1 incorporates § 4B1.2(b), which states that a
    “controlled substance offense” is “an offense under federal or state law, punishable by
    imprisonment for a term exceeding one year, that prohibits the manufacture, import,
    export, distribution, or dispensing of a controlled substance (or a counterfeit
    substance) . . . .” U.S.S.G. § 4B1.2(b) (emphasis added); see U.S.S.G. § 2K2.1 cmt. n.1
    (adopting the definition of “controlled substance” provided in § 4B1.2). Neither U.S.S.G.
    § 2K2.1 nor § 4B1.2(b) defines “counterfeit substance.”
    Mr. Thomas pled guilty to being a felon in possession of a firearm in violation of
    18 U.S.C. § 922(g)(1). Before that conviction, Mr. Thomas had pled guilty to two
    felonies: (1) robbery and (2) felony distribution of an imitation controlled substance
    under Colorado Revised Statute § 18-18-422(1)(a).
    At sentencing, the district court found that Mr. Thomas’s robbery conviction
    qualified as a “crime of violence” and his imitation controlled substance offense qualified
    2
    as a “controlled substance offense.” ROA, Vol. III at 53. It regarded the imitation
    controlled substance to be a “counterfeit substance” based on the “plain and ordinary
    meaning” of “counterfeit.” 
    Id. The court
    thus set Mr. Thomas’s base offense level at 24,
    which yielded a Guideline range of 57 to 71 months of imprisonment. It sentenced Mr.
    Thomas to 64 months in prison and three years of supervised release.2 Mr. Thomas
    reserved his right to appeal the district court’s ruling that his “imitation controlled
    substance” offense qualified as a “controlled substance offense” under U.S.S.G.
    § 2K2.1(a)(2). He filed a timely notice of appeal.
    On appeal, the parties dispute the meaning of “counterfeit substance” in
    § 4B1.2(b). Relying on dictionaries and “common meaning,” Maj. Op. at 4, the majority
    accepts the district court’s view that “counterfeit substance” is a substance that is “made
    in imitation of something else with intent to deceive,” ROA, Vol. III at 52-53; see Maj.
    Op. at 4.3 As the majority and the parties acknowledge, however, legislatures have
    adopted a different definition. The Controlled Substances Act (“CSA”), 18 U.S.C.
    § 802(7); 36 states and the District of Columbia; and the Uniform Controlled Substances
    Act use the term “counterfeit substance” to mean a mislabeled or misbranded controlled
    substance.4 This legislative definition is narrower than the dictionary-based definition
    2
    If the base offense level had been 20 instead of 24, Mr. Thomas’s Guideline
    range would have been 37 to 46 months.
    3
    As discussed below, the majority does not define “substance.”
    4
    The CSA defines “controlled substance” as “a drug or other substance, or
    immediate precursor, included in schedule I, II, III, IV, or V of part B of this subchapter.”
    3
    endorsed by the majority and district court. Under the legislative definition, Mr.
    Thomas’s prior Colorado offense would not qualify as a controlled substance offense
    under § 4B1.2(b), resulting in a lower advisory Guidelines range.
    *   *       *   *
    Before proceeding to the analytical discussion, a brief summary may be useful
    regarding three key terms: “controlled substance,” “counterfeit substance,” and
    “imitation controlled substance.” Only the first two terms appear in § 4B1.2(b):
    “controlled substance (or a counterfeit substance).” Under the district court’s and the
    majority’s reading of § 4B1.2(b), “counterfeit substance” includes “imitation controlled
    substance.” If “counterfeit substance” in § 4B1.2(b) is the legislative definition—a
    mislabeled controlled substance—the Guideline does not apply to an “imitation
    controlled substance” offense.
    21 U.S.C. § 802(6). It excludes alcohol and tobacco. 
    Id. It defines
    “counterfeit
    substance” as
    a controlled substance which, or the container or labeling of
    which, without authorization, bears the trademark, trade
    name, or other identifying mark, imprint, number, or device,
    or any likeness thereof, of a manufacturer, distributor, or
    dispenser other than the person or persons who in fact
    manufactured, distributed, or dispensed such substance and
    which thereby falsely purports or is represented to be the
    product of, or to have been distributed by, such other
    manufacturer, distributor, or dispenser.
    21 U.S.C. § 802(7).

    II. DISCUSSION
    “We interpret the Sentencing Guidelines according to accepted rules of statutory
    construction.” United States v. Marrufo, 
    661 F.3d 1204
    , 1207 (10th Cir. 2011)
    (quotations omitted). Although the majority relies on various approaches to support its
    definition of “counterfeit substance,” this case turns on whether the phrase’s meaning
    should be based on the dictionary and common meaning or on the definition legislated by
    the U.S. Congress and a substantial majority of state legislatures.
    The following discussion (A) explains why we should adhere to the legislative
    rather than the dictionary-based definition of “counterfeit substance,” and (B) responds to
    the majority’s points.
    A. Legislative Versus Dictionary Definition of “Counterfeit Substance”
    We should choose the legislative definition because it (1) provides a complete
    definition of “counterfeit substance”; (2) avoids the limitations inherent in dictionary
    definitions; (3) was promulgated by elected legislatures; and (4) stems from the drug
    enforcement context in which the Guideline term is used. See FAA v. Cooper, 
    566 U.S. 284
    , 291-99 (2012) (using legal context to define “actual damages”).
    First, only legislatures have fully defined the phrase “counterfeit substance” that
    appears in § 4B1.2(b). Dictionaries define “counterfeit,” but not “counterfeit substance.”
    The dictionary definition therefore omits half of the relevant language. See Sullivan v.
    Stroop, 
    496 U.S. 478
    , 483 (1990) (“But where a phrase in a statute appears to have
    become a term of art, . . . any attempt to break down the term into its constituent words is
    not apt to illuminate its meaning.”). When presented with competing definitions, we
    5
    should generally adopt the definition that defines the whole term rather than a portion of
    it.
    Second, although courts commonly consult dictionaries to understand statutory
    terms,5 dictionaries should not always be the first tool of interpretation, especially when a
    term has a widely recognized and established legislative definition. See Antonin Scalia &
    Brian A. Garner, Reading Law: The Interpretation of Legal Texts 73 (2012)
    (“Sometimes context indicates that a technical meaning applies. . . . And when the law is
    the subject, ordinary legal meaning is to be expected, which often differs from common
    meaning.”); see also Felix Frankfurter, Some Reflections on the Reading of Statutes, 47
    Colum. L. Rev. 527, 537 (1947) (“And if a word is obviously transplanted from another
    legal source, whether the common law or other legislation, it brings the old soil with it.”).
    The Supreme Court recently explained that when courts interpret a term with an
    established “legal lineage,” dictionaries have limited utility. See Hall v. Hall, 
    138 S. Ct. 1118
    , 1124-25 (2018) (declaring “[t]his is not a plain meaning case” and declining to rely
    on the dictionary definition of “consolidate” because the term had an established legal
    5
    See James J. Brudney & Lawrence Baum, Protean Statutory Interpretation in the
    Courts of Appeals, 58 Wm. & Mary L. Rev. 681 (2017) (empirical study of dictionary
    usage in the Supreme Court and Courts of Appeals). The reliance on dictionaries has
    extended to the Sentencing Guidelines. See, e.g., United States v. Wolf, 
    860 F.3d 175
    ,
    198 (4th Cir. 2017) (using dictionary definition to interpret Guideline term); United
    States v. Dougherty, 
    754 F.3d 1353
    , 1359 (11th Cir. 2014) (same).
    6
    meaning). Hall’s holding is in line with many others.6 This guidance favors the
    legislative definition over the dictionary in this case.7
    Third, legislators are elected, accountable lawmakers whose enactments defining a
    particular term should receive judicial deference relative to writers and editors of
    dictionaries. As Judge Mikva said, “Congress is like Humpty Dumpty in Through the
    Looking Glass. When Congress uses a word, the word means what Congress says it
    means, all the dictionary definitions to the contrary notwithstanding. If Congress has
    established what it wants a word to mean, that is what it means.” Abner J. Mikva, A
    Reply to Judge Starr’s Observations, 1987 Duke L.J. 380, 386 (1987). In this instance,
    38 legislatures have adopted a definition that is contrary to the district court’s dictionary-
    based definition. To reject this definition would “give a judge the relatively unrestrained
    6
    For example, the Supreme Court has instructed that “when Congress employs a
    term of art, it presumably knows and adopts the cluster of ideas that were attached to
    each borrowed word in the body of learning from which it was taken.” FAA v. Cooper,
    
    566 U.S. 284
    , 292 (2012) (quotations and citations omitted). It also has said that “[i]n the
    absence of contrary indication, we assume that when a statute uses [a term of art],
    Congress intended it to have its established meaning.” McDermott Int’l, Inc. v. Wilander,
    
    498 U.S. 337
    , 342 (1991). See also Binkley v. People, 
    716 P.2d 1111
    , 1113 (Colo. 1986)
    (“It is a cardinal rule of statutory construction . . . that a term which has acquired a
    technical or particular meaning, whether by legislative definition or otherwise, should be
    construed according to its acquired meaning.”).
    7
    “Dictionaries are most useful to determine what possible meanings a word might
    have, but they are not as useful for reaching closure on what words might mean in
    different contexts, nor are they always useful for determining the ordinary meaning of
    word clusters (like ‘driving a vehicle’) . . . .” William N. Eskridge, Jr., Interpreting Law:
    A Primer on How to Read Statutes and the Constitution 44 (2016).
    7
    power to look just at the statute’s words and at Webster’s Dictionary, and to decide with
    Webster’s what the law of the land will be.” 
    Id. The CSA
    does not state that its definition of “counterfeit substance” in § 802(7)
    shall apply to the Sentencing Guidelines. In that regard, the CSA’s definition cannot bind
    our understanding of § 4B1.2(b) under a “[l]egislative supremacy doctrine . . . of
    statutory interpretation.” Daniel A. Farber, Statutory Interpretation and Legislative
    Supremacy, 78 Geo. L.J. 281, 283 (1989). But the legislative definition is only a short
    step removed from the Guidelines because § 4B1.2(b) applies the term “counterfeit
    substance” to determine the sentencing consequences for violations of the criminal
    provisions in the CSA and state drug laws. Legislatures have defined this key term for
    this specific context. The dictionary writers have not, nor were they elected to do so.
    Fourth, context matters.8 “[W]ords may have different meanings when used in the
    context of a special subject, than they have in general usage.” United States v.
    Crittenden, 
    372 F.3d 706
    , 711 (5th Cir. 2004) (quotations omitted). As the Supreme
    Court has recognized, the context in which a word is used can alter a word’s meaning.
    See United States v. Castleman, 
    572 U.S. 157
    , 163-68 (2014) (defining “force”
    differently in the context of “violent felony” than in the context of “misdemeanor crime
    of domestic violence”); see also Stephen C. Mouritsen, The Dictionary Is Not a Fortress:
    Definitional Fallacies and a Corpus-Based Approach to Plain Meaning, 2010 B.Y.U. L.
    8
    Judge Posner observed, “Dictionary definitions are acontextual, whereas the
    meaning of sentences depends critically on context, including all sorts of background
    understandings.” United States v. Costello, 
    666 F.3d 1040
    , 1044 (7th Cir. 2012).
    8
    Rev. 1915 (2010) (criticizing courts’ reflexive reliance on dictionaries and arguing for a
    context-based approach to plain-meaning analyses).9
    In this case, the context of a Guideline using prior drug offenses to calculate a
    sentence is criminal drug enforcement.10 In defining the term “controlled substance
    offense,” § 4B1.2(b) uses the term “counterfeit substance,” putting it squarely in the
    category of offenses—state and federal—concerning criminal drug activity.11 State and
    federal legislatures define the crimes underlying a defendant’s prior convictions. And, as
    previously noted, the majority of states and the United States define “counterfeit
    substance” as Mr. Thomas proposes for § 4B1.2(b).
    Because Sentencing Guidelines regarding prior drug offenses fall squarely in the
    context of criminal drug laws, we should rely on legislators over lexicographers and
    9
    See Wilson v. Safelite Grp., Inc., 
    930 F.3d 429
    , 438-42 (6th Cir. 2019) (Thapar,
    J., concurring in part and in the judgment) (discussing merits of using context-based tools
    to determine plain meaning).
    10
    The primary audience for the Guidelines reinforces the point that § 4B1.2(b)
    was written for the criminal drug enforcement context. Given their complexity,
    “[i]ntricate guidelines are addressed not to potential criminals, but to the judges,
    prosecutors, and other officials who administer the criminal justice system.” Ronald F.
    Wright, Complexity and Distrust in Sentencing Guidelines, 25 U.C. Davis L. Rev. 617,
    618 (1992). As Professor Eskridge explains, the case for the “technical [meaning of]
    terms is strongest and most relevant” for rules “addressed to particular public or private
    officials and not to the general population.” Eskridge, supra note 7, at 60.
    11
    Justice Scalia, a leading proponent of dictionary usage, wrote that “[t]he
    meaning of terms on the statute books ought to be determined . . . on the basis of which
    meaning is (1) most in accord with context and ordinary usage, and . . . (2) most
    compatible with the surrounding body of law into which the provision must be
    integrated.” Green v. Bock Laundry Mach. Co., 
    490 U.S. 504
    , 528 (Scalia, J.,
    concurring).
    9
    interpret the term “counterfeit substance” in accordance with its established legal
    meaning. See 
    Hall, 138 S. Ct. at 1124-25
    (interpreting the term “consolidate” according
    to its legal, rather than common usage, definition).
    B. Responses to the Majority’s Other Points
    “As a general rule,” the majority agrees that “when dealing with a technical or
    specialized subject, we should understand terms in their technical or specialized
    meaning.” Maj. Op. at 7. The following addresses the majority’s arguments to avoid that
    “general rule” and use the dictionary definition instead.
    First, the majority relies on Johnson v. United States, 
    599 U.S. 133
    , 138-40
    (2010), in which the Supreme Court interpreted the meaning of the word “force” in the
    Armed Career Criminal Act and favored the dictionary over the common law definition.
    Maj. Op. at 7-8. The Court, however, started with the common law definition,
    recognized it as a term of art, and decided it did not “fit” with other terms in the statute,
    all before turning to the dictionary. In other words, the Court’s first option was the
    common law’s definition, not the dictionary’s.12 See also Chapman v. United States, 
    500 U.S. 453
    , 454 (1991) (stating that because “the Sentencing Guidelines do not define
    12
    The Supreme Court’s later decision in 
    Castleman, 572 U.S. at 168
    , applied
    Johnson and found that a “misdemeanor crime of domestic violence” is satisfied “by the
    degree of force that supports a common-law battery conviction.” Castleman therefore
    clarified that, where the common law definition of a term of art fits with other terms of
    the statute, courts need not resort to the dictionary definition. See 
    id. It reached
    that
    conclusion, in part, by looking to state assault and battery laws. 
    Id. at 167.
    10
    ‘mixture,’ and it has no established common-law meaning, it must be given its ordinary
    meaning”).13
    Our circuit follows a similar approach to understand references to generic offenses
    in the Guidelines. See, e.g., United States v. Rivera-Oros, 
    590 F.3d 1123
    , 1126-27 (10th
    Cir. 2009) (looking at “a wide range of sources . . . including federal and state statutes,
    the Model Penal Code, dictionaries, and treatises” to define the generic, contemporary
    meaning of an offense under the Guidelines).
    Second, the majority urges that applying the legislative definition of “counterfeit
    substance” to § 4B1.2(b) would make “(or a counterfeit substance)” redundant. Maj. Op.
    at 8-9. This would, the majority states, “add[] no substantive content” to § 4B1.2(b)’s
    definition of “controlled substance offense” because “every counterfeit substance is
    already a controlled substance.” 
    Id. at 8.
    The majority relies heavily on this canon. But the redundancy (or surplusage)
    canon is not always conclusive and may be discounted in statutory interpretation. See
    Lamie v. United States Tr., 
    540 U.S. 526
    , 536 (2004) (“[O]ur preference for avoiding
    surplusage constructions is not absolute.”); Chickasaw Nation v. United States, 
    534 U.S. 13
              In another case called Johnson v. United States, 
    529 U.S. 694
    , 706-08 (2000),
    the Supreme Court bypassed a dictionary definition when it was clear Congress had
    intended a different meaning. The Court held that a provision in the 1984 Sentencing
    Reform Act that authorized a district court to “revoke” a term of supervised release and
    send the defendant back to prison also allowed the imposition of a further term of
    supervised release after the incarceration. 
    Id. at 703-07.
    The Court acknowledged that
    the primary dictionary definition of “revoke” is “to annul by recalling or taking back.”
    
    Id. at 704
    (quoting Webster’s Third New International Dictionary 1944 (1981)). But it
    concluded that Congress wanted to use “revoke” in an unconventional sense, “allowing a
    ‘revoked’ term of supervised release to retain vitality after revocation.” 
    Id. at 707.
                                                 11
    84, 94 (2001); Scalia & 
    Garner, supra, at 176-79
    .14 As the Supreme Court recently
    explained,
    If one possible interpretation of a statute would cause some
    redundancy and another interpretation would avoid
    redundancy, that difference in the two interpretations can
    supply a clue as to the better interpretation of a statute. But
    only a clue. Sometimes the better overall reading of the
    statute contains some redundancy.
    Rimini St., Inc. v. Oracle USA, Inc., 
    139 S. Ct. 873
    , 881 (2019). In the Guidelines
    context, the Fifth Circuit has held that the “canon is inapt in the context of [U.S.S.G. §]
    4A1.1, in which the [Sentencing] Commission was trying to account for myriad
    ‘jurisdictional variations in offense definitions, sentencing structures, and manner of
    sentence pronouncement.’” United States v. Enrique-Ascencio, 
    857 F.3d 668
    , 675 (5th
    Cir. 2017) (quoting U.S.S.G. § 4A1.1 cmt. background). Stated succinctly,
    “[r]edundancy is not a silver bullet.” Rimini 
    St., 139 S. Ct. at 881
    .
    Moreover, parentheticals are often used to clarify terms. Here, the § 4B1.2(b)
    parenthetical may reasonably be read to clarify that “controlled substance offense”
    includes the legislative definition of “counterfeit substance.”15 See Mizrahi v. Gonzales,
    14
    “Sometimes drafters do repeat themselves and do include words that add
    nothing of substance, either out of a flawed sense of style or to engage in the ill-
    conceived but lamentably common belt-and-suspenders approach.” Scalia & 
    Garner, supra, at 176-77
    . See also Linda D. Jellum, Mastering Statutory Interpretation 104
    (2008) (“Statutes are not always carefully drafted. Legal drafters often include redundant
    language on purpose to cover any unforeseen gaps or simply for no good reason at all.”).
    15
    Under the Controlled Substances Act, a “counterfeit substance” offense is not
    the same as a “controlled substance” offense. As defined by statute, a “controlled
    substance” is (1) “a drug or other substance,” (2) as defined in separate “schedules,” and
    (3) is not alcohol or tobacco. 21 U.S.C. § 802(6). A “counterfeit substance” is (1) a
    12
    
    492 F.3d 156
    , 166 (2d Cir. 2007) (noting that the disjunctive parenthetical in 8 U.S.C.
    § 1182(a)(2)(A)(i)(II) “need not be assigned a different meaning from the preceding
    language to avoid being surplusage; it can reasonably be construed to illustrate or explain
    the broader proposition”).
    A reader of § 4B1.2(b) would benefit from this clarification given that “controlled
    substance” and “counterfeit substance” appear side-by-side in the U.S. Code. The
    definition of “counterfeit substance” in 21 U.S.C. § 802(7) is separate from and comes
    immediately after the definition of “controlled substance” in § 802(6). Similarly,
    21 U.S.C. § 841(a)(1) makes it unlawful “to manufacture, distribute, or dispense, or
    possess with intent to manufacture, distribute, or dispense, a controlled substance,” while
    the next subsection, 21 U.S.C. § 841(a)(2), makes it unlawful “to create, distribute, or
    dispense, or possess with intent to distribute or dispense, a counterfeit substance.”16 The
    controlled substance, (2) mislabeled to look like it was produced by another person, and
    (3) which thereby purports to be from that person. 
    Id. § 802(7).
    Thus, “counterfeit
    substance” incorporates the definition of “controlled substance,” but it includes additional
    requirements.
    Similarly, most states have “controlled substance” offenses that are distinct from
    “counterfeit substance” offenses. They also have distinct “imitation controlled
    substance” offenses. Colorado provides an example. See Colo. Rev. Stat. Ann.
    § 18-18-405 (controlled substances); 
    id. § 18-18-422
    (imitation controlled substances);
    
    id. § 18-18-423
    (counterfeit controlled substances).
    16
    The majority notes that § 841(a)(1) uses the word “manufacture,” while
    § 841(a)(2) instead uses “create.” It then points out that § 4B1.2(b) uses “manufacture”
    and suggests that the Guideline’s word choice is significant. See Maj. Op. at 13. The
    difference between (a)(1) and (a)(2) may suggest there is a difference between
    manufacturing a controlled substance and creating a counterfeit substance, but it does not
    change that, under § 802(7), a “counterfeit substance” is necessarily a “controlled
    substance.” In other words, if the definition of “counterfeit substance” is redundant in
    13
    terms “controlled” and “counterfeit” substance are related and often appear together. But
    they are not the same. The parenthetical in § 4B1.2(b) thus serves a useful, non-
    redundant clarifying function.
    Third, the majority discounts § 4B1.2(b)’s placement of “or a counterfeit
    substance” in a parenthetical. Maj. Op. at 9-11. In general, parentheses “indicate a word,
    phrase, or clause that has been interjected by way of explanation or qualification” and are
    used to “set off an inserted phrase, clause, or sentence that [the author] want[s] to
    minimize.” Bryan A. Garner, The Chicago Guide to Grammar, Usage, and Punctuation
    365 (2016) (emphasis added). The majority, however, would have us “give substantive
    effect to language in [the] parenthetical” by interpreting “(or a counterfeit substance)” to
    “expand[] the relevant offenses to encompass those involving fake controlled
    substances.” Maj. Op. at 10. This interpretation would significantly enlarge the
    substantive scope of the Guideline to cover multiple state offenses. Indeed, the district
    court’s definition would expand the term “controlled substance offense” in § 4B1.2(b) to
    include offenses that do not involve controlled substances, such as Mr. Thomas’s sale of
    rocks and sand made to look like heroin. The substantive reach of the district court’s and
    majority’s reading would seem to merit more than a mere parenthetical.
    This is especially so because state law “imitation controlled substance” offenses—
    such as Mr. Thomas’s—are not punishable under the federal narcotics laws. See United
    § 4B1.2(b), then, under the majority’s logic, it must also be redundant under 21 U.S.C.
    § 802(6) and § 802(7).
    14
    States v. Sampson, 
    140 F.3d 585
    , 589 (4th Cir. 1998) (“Simply because a substance looks
    like cocaine, and the defendant misrepresents to his unsuspecting purchaser that the
    substance is cocaine, does not make the mere distribution of that substance a violation of
    the federal narcotics laws.”). Moreover, states like Colorado label “imitation controlled
    substance” offenses as such. See, e.g., Colo. Rev. Stat. Ann. § 18-18-420(3). If the
    Commission wished to include those offenses in its definition of “controlled substance
    offenses,” it could easily have added the word “imitation.”
    Fourth, the majority emphasizes the Commission’s use of the word “or” in “(or
    counterfeit substance),” noting that the Commission generally uses “or” in parentheticals
    to “expand[] the scope of [a] guideline to include things that would generally not be
    considered subsets of the term.” Maj. Op. at 12. The majority’s ensuing point is
    well-taken that the case for the legislative definition of “counterfeit substance” would be
    stronger if § 4B1.2(b) had said “(including a counterfeit substance)” instead of “(or a
    counterfeit substance).” But the majority’s expansive interpretation of “counterfeit
    substance” would take the point too far, broadening the Guideline’s coverage more than
    the Commission’s other “or” parentheticals. See, e.g., U.S.S.G. § 2B1.1 cmt. n.10(D)
    (using an “or” parenthetical to expand “name” to include “or other identifying
    information”). Maj. Op. at 12.17 The “or” parenthetical here is more consistent with its
    17
    The majority’s point that § 4B1.2(b) contains ten commas should draw the
    attention of drafting stylists, but whether commas, parentheticals, or nothing surrounds
    the words “counterfeit substance” does not make the case for the dictionary-based
    definition of “counterfeit substance” any stronger. Indeed, as noted above, using
    parentheticals around a phrase that, under the majority’s understanding, would
    15
    clarifying message that the Guideline covers controlled substance offenses as defined in
    the federal and most criminal codes. See 
    Mizrahi, 492 F.3d at 166
    (concluding that the
    “or” parenthetical in 8 U.S.C. § 1182(a)(2)(A)(i)(II) “can reasonably be construed to
    illustrate or explain the broader proposition” (emphasis added)).
    Fifth, the majority points to the lack of any cross-reference to the statutory
    definition of “counterfeit substance” in § 4B1.2(b) in contrast to Application Note 4 to
    U.S.S.G. § 2D1.1, which states that “counterfeit substances” are defined in 21 U.S.C.
    § 802(7) as “controlled substances that are falsely labeled.” See Maj. Op. at 13-14. This
    point would carry more weight were it not for the Background Commentary to § 4B1.1
    and its reference to 28 U.S.C. § 994(h). Section 994(h) provides for sentencing
    enhancements under the Guidelines for persons convicted of counterfeit substance
    offenses under 21 U.S.C. § 841, which in turn criminalizes counterfeit substance offenses
    based on § 802(7)’s definition. See 
    Crittenden, 372 F.3d at 711
    (Dennis, J., dissenting in
    part) (finding the CSA’s “definition of the term ‘counterfeit substance’ has been
    effectively incorporated into the Guidelines”). This cross-reference to § 802(7) is,
    however, admittedly attenuated because it is not explicit and does not appear in
    § 4B1.2(b).
    More telling is that courts routinely incorporate the CSA’s definition of
    “controlled substance” into their Guidelines analysis even when the applicable Guidelines
    incorporate multiple state imitation drug offenses into the Guideline does not seem to be
    the obvious punctuation choice.
    16
    section does not cross-reference the Act. See United States v. Sanchez-Garcia, 
    642 F.3d 658
    , 661-62 (8th Cir. 2011) (noting § 4B1.2(b) does not define “controlled substance”
    and using the CSA’s definition to determine whether prior conviction qualified as a
    “controlled substance offense”).18 In doing so, they draw on the legislative definition of
    “controlled substance” and the well-established body of law surrounding it. See 
    id. To illustrate,
    U.S.S.G. § 2L1.2 does not define “controlled substance,” but it defines a “drug
    trafficking offense” using materially identical language to U.S.S.G. § 4B1.2(b)’s
    definition of “controlled substance offense.”19 Yet even without a cross-reference, courts
    assume the CSA’s legislative definition of a “controlled substance” applies. See, e.g.,
    United States v. Leiva–Deras, 
    359 F.3d 183
    , 189 (2d Cir. 2004) (using the CSA to
    determine whether a prior conviction meets the criteria for a “drug trafficking offense”
    under U.S.S.G. § 2L1.2(b)(1)(A)(i)). Given that § 4B1.2(b) does not define “controlled
    18
    See also United States v. Kelly, 
    991 F.2d 1308
    , 1316 (7th Cir. 1993) (using the
    CSA to determine if marijuana is a “controlled substance” under U.S.S.G. § 2K2.1(a));
    United States v. Madkins, 
    866 F.3d 1136
    , 1144 (10th Cir. 2017) (relying on the CSA to
    define the word “distribute” under U.S.S.G. § 4B1.2(b)); United States v. Gardner, 
    534 F. Supp. 2d 655
    , 660-61 (W.D. Va. 2008) (holding that defendant’s imitation controlled
    substance conviction was not a “felony drug offense” for the purposes of a statutory
    sentencing enhancement under 21 U.S.C. § 841(b)(1)(A)).
    19
    Under § 2L1.2, a “drug trafficking offense” is “an offense under federal, state,
    or local law that prohibits the manufacture, import, export, distribution, or dispensing of,
    or offer to sell a controlled substance (or a counterfeit substance) or the possession of a
    controlled substance (or a counterfeit substance) with intent to manufacture, import,
    export, distribute, or dispense.” U.S.S.G. § 2L1.2, cmt. n.2; see United States v. Walker,
    
    858 F.3d 196
    , 200 n.4 (4th Cir. 2017) (“The Guidelines’ definition of ‘controlled
    substance offense’ is substantively identical to the definition of ‘drug trafficking offense’
    at issue here.”).
    17
    substance” or “counterfeit substance,” and that courts rely on the CSA to understand the
    meaning of “controlled substance,” courts should rely on the CSA’s definition of
    “counterfeit substance” in § 802(7) for consistent Guidelines interpretation.
    Sixth, the majority cites decisions from five other circuits that have reached the
    same conclusion it has reached. Maj. Op. at 17-19.20 But two of the decisions drew
    dissents, see 
    Crittenden, 372 F.3d at 710
    (Dennis, J., dissenting in part); United States v.
    Frazier, 
    89 F.3d 1501
    , 1508 (11th Cir. 1996) (Godbold, J. dissenting in part), and the
    Seventh Circuit correctly recognized that the issue presents a “surprisingly complicated
    question,” United States v. Hudson, 
    618 F.3d 700
    , 701 (7th Cir. 2010). We are, of
    course, not bound by out-of-circuit decisions.21
    We have departed from our sibling circuits when we disagree with them. See
    Jewell v. United States, 
    749 F.3d 1295
    , 1300 (10th Cir. 2014) (“We are hesitant to create
    a circuit split, but we have little choice because we are obliged to follow the Supreme
    Court’s holding . . . even if other circuit courts have not.”); see also United States v.
    20
    See United States v. James, 712 F. App’x 838, 840 (11th Cir. 2017)
    (unpublished) (citing United States v. Frazier, 
    89 F.3d 1501
    , 1505 (11th Cir. 1996));
    United States v. Hudson, 
    618 F.3d 700
    , 705 (7th Cir. 2010); United States v. Mills, 
    485 F.3d 219
    , 225 (4th Cir. 2007); United States v. Robertson, 
    474 F.3d 538
    , 541 (8th Cir.
    2007); 
    Crittenden, 372 F.3d at 709
    .
    21
    Neither are the district courts in this circuit. Since Mr. Thomas’s sentence and
    conviction, at least two district court decisions in the Tenth Circuit addressed the issue.
    See United States v. Horton, 17-CR-00048-RM, Dist. Ct. Docs at 44, 48 (D. Colo. Sept.
    15, 2017) (sentencing transcript not published); United States v. Pigford, No. 16-CR-
    00181-LTB, Dist. Ct. Doc. at 35 (D. Colo. Sept. 13, 2016) (same). In both, the district
    court agreed with the defendant, declining to accept the government’s argument that the
    dictionary definition should be applied to “counterfeit” under U.S.S.G. § 4B1.2(b).
    18
    Games-Perez, 
    695 F.3d 1104
    , 1123 n.7 (10th Cir. 2012) (Gorsuch, J., dissenting from
    denial of reh’g en banc) (“Although we are hesitant to create a circuit split, we must
    follow the unambiguously expressed intent of Congress.” (quotations and alterations
    omitted)). Recently, in Bandimere v. SEC, 
    844 F.3d 1168
    (10th Cir. 2016), we split with
    the D.C. Circuit notwithstanding the dissent’s forceful criticism of our decision to do so.
    See 
    id. at 1201
    (McKay, J., dissenting) (“[T]he majority is resolved to create a circuit
    split. When there are competing understandings of Supreme Court precedent, I would
    prefer the outcome that does the least mischief.”). The Supreme Court ultimately agreed
    with our view of the issue. See Lucia v. SEC, 
    138 S. Ct. 2044
    , 2050-51 (2018).22
    In delegating to the Sentencing Commission the statutory duty “periodically [to]
    review and revise” the Guidelines, 28 U.S.C. § 994(o), “Congress necessarily
    contemplated that the Commission would periodically review the work of the courts, and
    would make whatever clarifying revisions to the Guidelines conflicting judicial decisions
    might suggest,” Braxton v. United States, 
    500 U.S. 344
    , 348 (1991). Advancing a
    contrary position on a Guideline interpretation alerts the Commission to take a second
    look.23
    22
    Rigid adherence to prudential avoidance of a circuit split would give the first
    circuit to consider an issue the power to decide it for all circuits. As then-Professor
    Posner noted, “[A] difficult legal question is more likely to be answered correctly if it is
    allowed to engage the attention of different sets of judges deciding factually different
    cases than if it is answered finally by the first panel to consider it.” Richard A. Posner,
    The Federal Courts: Crisis and Reform 163 (1985).
    23
    See Samuel Estreicher & John Sexton, Redefining the Supreme Court’s Role: A
    Theory of Managing the Federal Judicial Process 48 (1986) (“From the absence of a rule
    19
    I share the majority’s reluctance about creating a circuit split. But I am wary
    about subordinating the decisions of elected legislators, who have defined the term at
    issue here, to those of lexicographers, who have defined only half of the term for all
    contexts, for the sake of acquiescing to out-of-circuit decisions.
    Seventh, the majority relies on the Sentencing Commission’s inaction in the face
    of the circuit opinions that have addressed this issue. Maj. Op. at 19-25. This court has
    been reluctant to rely on Commission inaction. See United States v. Smith, 
    133 F.3d 737
    ,
    748 (10th Cir. 1997) (“Since no guideline amendments were proposed, [the defendant]
    interprets the Commission’s inaction as endorsing the adequacy of the existing
    guidelines. [The defendant] reads too much into the Commission’s inaction.”); see also
    United States v. Marshall, 
    998 F.2d 634
    , 636 n.4 (8th Cir. 1993) (“Several years of
    inaction arguably suggests Congressional and Sentencing Commission satisfaction with
    the current situation, but we do not discount the force of inertia in governmental
    affairs.”); Advanced Micro Devices v. C.A.B., 
    742 F.2d 1520
    , 1541 (D.C. Cir. 1984)
    (“The general rule is that congressional inaction or congressional action short of the
    enactment of positive law, like postenactment legislative history, is often entitled to no
    weight in construing a statute.”) (citing and discussing scholarly commentary).
    Why has the Commission not clarified § 4B1.2(b)? We could speculate that the
    Commission’s inaction connotes approval of judicial interpretation of the Guidelines, or
    of intercircuit stare decisis . . . we derive a basic premise that disuniformity, at least in the
    short run, may be tolerable and perhaps beneficial.”).
    20
    that the Commission instead has focused more on addressing circuit splits.24 But
    engaging in this conjecture would raise a host of questions, including: (1) How long
    must the Commission fail to act before we draw meaning from its silence? (2) How
    many circuits must weigh in on the issue before we decide that view is established? (3)
    Do district court opinions count? (4) Does an inference from Commission inaction
    require judicial consensus? And (5) do dissenting opinions matter? Although
    Commission inaction may “offer[] . . . a modicum of . . . support” for an existing
    interpretation in some circumstances, see United States v. Rosales-Garcia, 
    667 F.3d 1348
    , 1355 (10th Cir. 2012), interpreting the Commission’s silence can be a speculative
    exercise. This factor does not, in my view, outweigh the predominant legislative
    definition of “counterfeit substance.”
    III. CONCLUSION
    The majority relies on the dictionary, a concern about redundancy, the lack of a
    cross-reference in § 4B1.2(b) to § 802(7), fear of a circuit split, and Commission inaction.
    The redundancy concern is unpersuasive. On the cross-reference point, the context in
    which § 4B1.2(b) falls and the foregoing discussion provide countervailing
    considerations. The prudential concern about a circuit split is legitimate but overstated.
    24
    Indeed, many amendments to the Guidelines have addressed “circuit conflicts.”
    The majority identifies 12 such amendments since 2011. Maj. Op. at 23. I count at least
    49 overall. See U.S.S.G. app. C, amends. 472, 500, 549, 552, 564, 566, 568, 572, 579,
    577, 580, 581, 582, 583, 591, 597, 602, 603, 604, 613, 614, 615, 617, 630, 632, 634, 635,
    645, 660, 664, 667, 691, 693, 709, 731, 732, 741, 752, 759, 764, 766, 767, 774, 775, 780,
    786, 794, 795, 801 (effective Nov. 1, 2018).
    21
    And Commission inaction is unconvincing. The case for the legislative definition is
    stronger than for the dictionary.
    We should adhere to the established legal meaning of “counterfeit substance” as
    defined by 36 state legislatures, the District of Columbia, the Uniform Substances Act,
    and the U.S. Congress. Because Mr. Thomas’s imitation controlled substance offense
    does not fit within that definition, I would remand for the district court to resentence him
    under a properly calculated Guideline range.
