    SUMMARY ***
    Criminal Law
    The panel affirmed in part, reversed in part, and
    remanded for resentencing in a case in which Robert
    Anthony House pleaded guilty to being a prohibited person
    in possession of a firearm in violation of 
    18 U.S.C. § 922
    (g)(1) and (g)(3).
    At sentencing, the district court ruled that two of House’s
    prior felony convictions—a 2007 conviction under Montana
    Code Annotated § 45-9-103 for criminal possession of
    dangerous drugs with intent to distribute (“2007 marijuana
    conviction”) and a 2013 conviction under Montana Code
    Annotated §§ 45-2-302 and 45-9-101 for accountability as
    to criminal distribution of dangerous drugs (“2013 cocaine
    conviction”)—qualified as “controlled substance offenses”
    under USSG § 4B1.2(b). The district court, in turn, applied
    the enhancement in USSG § 2K2.1(a)(2).
    The panel accepted the government’s concession that
    United States v. Bautista, 
    989 F.3d 698
     (9th Cir. 2021), is
    controlling as to the sentencing enhancement based on the
    2007 marijuana conviction, and that this court should

    This summary constitutes no part of the opinion of the court. It
    has been prepared by court staff for the convenience of the reader.
    UNITED STATES V. HOUSE                      3
    remand for resentencing without treating the marijuana
    conviction as a qualifying offense.
    As to whether the 2013 cocaine conviction is a
    qualifying prior controlled substance offense, House raised
    two arguments.
    House first argued that “the plain language of the
    § 4B1.2 guideline and commentary definition of a controlled
    substance offense does not include offers to engage in
    prohibited conduct,” while Montana's accountability statutes
    do, rendering the latter categorically overbroad. Because it
    was bound by United States v. Crum, 
    934 F.3d 963
     (9th Cir.
    2019) (per curiam), the panel held that although Montana’s
    accountability statutes include offers to engage in prohibited
    conduct, they are not rendered categorically overbroad with
    respect to §§ 4B1.2(b) and 2K2.1(a).
    House argued, second, that Montana's drug statute is
    categorically overbroad because its definition of cocaine
    includes substances that are either not set forth in the federal
    definition and/or are specifically excluded. Because House
    raises new arguments on appeal, the panel reviewed the
    district court’s sentencing calculation for plain error as to
    those contentions. The panel observed (1) that when the
    district court reached its decision that a cocaine conviction
    under Montana Code Annotated §§ 45-9-101 and 50-32-
    224(1)(d) could constitute a controlled substance offense
    under § 4B1.2(b), there was no (and there still is no) binding
    precedent to the contrary; and (2) that certain of the grounds
    for the district court’s rulings were not rejected in binding
    precedent until after its sentencing decision. The panel
    concluded, accordingly, that the district court did not commit
    plain error with respect to the cocaine overbreadth issue.
    4                UNITED STATES V. HOUSE
    Concurring, Judge Graber wrote separately to explain
    her views concerning overbroad state statutes. She noted
    that the general rule is that a state law cannot be considered
    broader than a federal law if the state law’s breadth is
    imagined or theoretical. In her view, this court has
    distinguished between overbreadth that is “evident” from the
    statute’s text, when a defendant may rely on the statutory
    language to establish the statute as overly inclusive, and
    overbreadth that is not “evident” from the text, when the
    party arguing for overbreadth must find a relevant case
    establishing a realistic probability of overbroad application.
    Concurring, Judge Christen wrote separately because the
    complicated categorical approach has proven inordinately
    time consuming, and this court’s prior consideration of
    Montana’s cocaine statute may result in confusion regarding
    the methodology set forth in Taylor v. United States,
    
    495 U.S. 575
     (1990). She wrote that, in her view, the
    categorical approach employed in United States v. Holliday,
    853 F. App’x 53 (9th Cir. 2021), skipped an important step
    by taking the holdings from United States v. Grisel, 
    488 F.3d 844
     (9th Cir. 2007) (en banc), abrogated on other grounds
    as recognized by United States v. Stitt, 
    139 S. Ct. 399
     (2018),
    and United States v. Bautista, 
    989 F.3d 698
     (9th Cir. 2021),
    out of context.
    Concurring, District Judge Wu wrote separately to
    specifically address the categorical/modified categorical
    analysis as it relates to the cocaine overbreadth issue in the
    context of Montana Code Annotated § 50-32-224(1)(d). He
    would apply the reasonable probability factor articulated in
    Gonzales v. Duennas-Alvarez, 
    549 U.S. 183
     (2007), as
    further considered in Moncrieffe v. Holder, 
    569 U.S. 184
    (2013), in initially determining whether the definition of
    UNITED STATES V. HOUSE                            5
    cocaine in § 50-32-224(1)(d) is a categorical match with the
    federal regulatory definition at 
    21 C.F.R. § 13-08.12
    (b)(4).

    OPINION
    PER CURIAM:
    On January 23, 2020, Robert Anthony House pleaded
    guilty to two counts of being a “prohibited person” in
    possession of a firearm in violation of 
    18 U.S.C. § 922
    (g)(1)
    and (g)(3). 1 At sentencing on August 5, 2020, the district
    court ruled that two of his prior felony convictions—a 2007
    conviction under Montana Code Annotated section 45-9-103
    for criminal possession of dangerous drugs (i.e., marijuana 2)
    1
    Title 
    18 U.S.C. § 922
    (g)(1) prohibits a convicted felon from
    possessing a firearm. Title 
    18 U.S.C. § 922
    (g)(3) bars such possession
    by a person “who is an unlawful user of or addicted to any controlled
    substance (as defined in section 102 of the Controlled Substances Act
    (
    21 U.S.C. § 802
    )).”
    2
    The Montana criminal statutes use both spellings, i.e., “marijuana”
    and “marihuana,” for that controlled substance. See, e.g., Montana Code
    6                   UNITED STATES V. HOUSE
    with intent to distribute (“2007 marijuana conviction”) and
    a 2013 conviction under Montana Code Annotated sections
    45-2-302 and 45-9-101 for accountability as to criminal
    distribution of dangerous drugs (i.e., cocaine) (“2013
    cocaine conviction”)—qualified as “controlled substance
    offenses” under United States Sentencing Commission
    Guidelines Manual (“USSG”) § 4B1.2(b). Over House’s
    objections, the court applied the sentencing enhancement in
    USSG § 2K2.1(a)(2). House appeals. We affirm in part,
    reverse in part, and remand for resentencing.
    I. APPLICABLE LAW
    For context, we provide a brief overview of the
    convoluted law that has developed concerning the issues
    raised in this appeal.
    USSG § 2K2.1(a)(2) assigns a base offense level of 24
    to a defendant convicted under 
    18 U.S.C. § 922
    (g) if the
    defendant has previously sustained at least two felony
    convictions of either a “crime of violence” as defined in
    USSG § 4B1.2(a) or a “controlled substance offense” as
    defined in § 4B1.2(b). If the defendant has only one such
    prior conviction, the base offense level is 20. See
    § 2K2.1(a)(4). If the defendant has none, the base level is
    14. See § 2K2.1(a)(6). USSG § 2K2.1(a) does not define
    what constitutes a “controlled substance offense,” but
    Application Note 1 of the Commentary to § 2K2.1 states that
    it “has the meaning given that term in § 4B1.2(b) and
    Annotated section 50-32-101(18). Although both spellings are also
    found in various federal criminal statutes, in 
    21 U.S.C. § 802
    (16), which
    sets out a definition of the drug, it is spelled “marihuana.”
    UNITED STATES V. HOUSE                               7
    Application Note 1 of the Commentary to § 4B1.2[.]”
    § 2K2.1 cmt. n.1. In turn, § 4B1.2(b) states:
    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.
    Application Note 1 of the Commentary to § 4B1.2 expands
    the prohibited conduct by providing that “‘controlled
    substance offense’ include[s] the offenses of aiding and
    abetting, conspiring, and attempting to commit such
    offenses.” 3
    To determine whether a prior state conviction qualifies
    as a controlled substance offense for purposes of the federal
    Sentencing Guidelines, we apply a three-step analysis. See
    3
    Federal circuit courts are split as to whether Application Note 1’s
    expansion of the types of prohibited conduct that can constitute a
    controlled substance offense lacks legal force because it goes beyond the
    text of USSG § 4B1.2(b) itself. See United States v. Crum, 
    934 F.3d 963
    ,
    966 (9th Cir. 2019) (per curiam) (collecting cases). In Crum, we held
    that we were “compelled by our court’s prior decision in United States
    v. Vea-Gonzales, 
    999 F.2d 1326
     (9th Cir. 1993), overruled on other
    grounds by Custis v. United States, 
    511 U.S. 485
     (1994), to [conclude]
    . . . that Application Note 1 of § 4B1.2 is ‘perfectly consistent’ with the
    text of § 4B1.2(b) . . . . [and] that Application Note 1 properly interprets
    the definition of the term ‘controlled substance offense’ to encompass
    aiding and abetting, conspiracy, attempt, and other forms of the
    underlying offense.” 934 F.3d at 966-67.
    8                UNITED STATES V. HOUSE
    United States v. Martinez-Lopez, 
    864 F.3d 1034
    , 1038 (9th
    Cir. 2017) (en banc); United States v. Figueroa-Beltran,
    
    892 F.3d 997
    , 1001 (9th Cir. 2018). “First, we ask whether
    the state law is a categorical match with a federal drug
    trafficking offense.” Martinez-Lopez, 864 F.3d at 1038
    (citing Taylor v. United States, 
    495 U.S. 575
    , 599–600
    (1990)). In this initial step,
    we look only to the “statutory definitions” of
    the corresponding offenses.           [Taylor,
    495 U.S.] at 600. If a state law “proscribes
    the same amount of or less conduct than” that
    qualifying as a federal drug trafficking
    offense, then the two offenses are a
    categorical match.        United States v.
    Hernandez, 
    769 F.3d 1059
    , 1062 (9th Cir.
    2014) (per curiam). In that scenario, a
    conviction under state law automatically
    qualifies as a predicate drug trafficking
    offense—ending our analysis.
    Martinez-Lopez, 864 F.3d at 1038; see also Crum, 934 F.3d
    at 964. The categorical-match analysis typically focuses on
    one or both of the following subjects: (1) the criminal
    conduct necessary for the state trafficking conviction (i.e.,
    the actus reus requirements), see, e.g., United States v.
    Rivera-Sanchez, 
    247 F.3d 905
    , 908–09 (9th Cir. 2001) (en
    banc) (comparing California’s statute criminalizing the
    transportation of marijuana, which included solicitation
    offenses, with the federal Controlled Substances Act, which
    at that time did not), superseded on other grounds as
    recognized in Martinez-Lopez, 864 F.3d at 1038; or (2) the
    types or varieties of the substance that fall within the
    definition of the outlawed drug (i.e., the scope of the
    designated controlled substances), see, e.g., United States v.
    UNITED STATES V. HOUSE                      9
    Bautista, 
    989 F.3d 698
    , 704–05 (9th Cir. 2021) (comparing
    an Arizona criminal statute that included hemp in its
    definition of marijuana with the federal Controlled
    Substances Act, which was amended in 2018 to exclude
    hemp from the federal definition of marijuana).
    If there is not a categorical match, we proceed to the
    second step and consider whether the state statute is
    “divisible”—i.e., whether it “sets out one or more elements
    of the offense in the alternative.” Martinez-Lopez, 864 F.3d
    at 1038 (quoting Descamps v. United States, 
    570 U.S. 254
    ,
    257 (2013)). “A single statute may list elements in the
    alternative, and thereby define multiple crimes.” Mathis v.
    United States, 
    136 S. Ct. 2243
    , 2249 (2016).
    If there is not a categorical match but the state statute is
    divisible, we proceed to the third step of the analysis and
    apply the modified categorical approach, where we examine
    judicially noticeable documents of conviction “to determine
    which statutory phrase was the basis for the conviction.”
    Descamps, 570 U.S. at 263 (quoting Johnson v. United
    States, 
    559 U.S. 133
    , 144 (2010)). If the defendant pleaded
    to (or was found guilty of) the elements that constitute a
    federal drug trafficking crime, “the prior state conviction
    may serve as a predicate offense under the sentencing
    guidelines.” Martinez-Lopez, 864 F.3d at 1039.
    The Supreme Court has identified an additional factor for
    courts to consider in the categorical/modified categorical
    analyses. In Gonzales v. Duenas-Alvarez, 
    549 U.S. 183
    (2007), the Court stated:
    [I]n our view, to find that a state statute
    creates a crime outside the generic definition
    of a listed crime in a federal statute requires
    more than the application of legal
    10               UNITED STATES V. HOUSE
    imagination to a state statute’s language. It
    requires a realistic probability, not a
    theoretical possibility, that the State would
    apply its statute to conduct that falls outside
    the generic definition of a crime. To show
    that realistic probability, an offender, of
    course, may show that the statute was so
    applied in his own case. But he must at least
    point to his own case or other cases in which
    the state courts in fact did apply the statute in
    the special (nongeneric) manner for which he
    argues.
    
    Id. at 193
    . We have applied the Duenas-Alvarez’s holding
    on several occasions. See, e.g., United States v. Rodriguez-
    Gamboa, 
    972 F.3d 1148
    , 1150 (9th Cir. 2020) (concluding
    that California’s statute prohibiting possession for sale of
    both the geometric and optical isomers of methamphetamine
    was not categorically overbroad—even though the federal
    statute outlaws only possession of methamphetamine’s
    optical isomers—because there was “unrebutted expert
    testimony . . . that there is no such thing as a geometric
    isomer of methamphetamine”); United States v. Perez,
    
    932 F.3d 782
    , 788–89 (9th Cir. 2019) (holding that a
    California statute criminalizing intentional use of physical
    force that results in serious bodily injury was a crime of
    violence even though the defendant found two state appellate
    decisions that “dream[ed] up unusual scenarios” in which a
    non-violent act could conceivably inflict substantial bodily
    injury (alterations in original) (internal quotation marks
    omitted)), cert. denied, 
    140 S. Ct. 2723
     (2020).
    UNITED STATES V. HOUSE                             11
    II. BACKGROUND
    The government recommended a base offense level of 24
    under USSG § 2K2.1(a)(2) because House had two prior
    felony convictions for controlled substance offenses under
    § 4B1.2(b). In his sentencing memorandum, House argued
    that his 2007 marijuana conviction did not qualify as a
    “controlled substance offense” within § 4B1.2(b) because
    the Montana statute criminalized more conduct than its
    federal analogue. Specifically, the federal definition of
    marijuana was amended in 2018 to expressly exclude hemp,
    whereas the Montana statute does not contain that exclusion.
    Compare 
    21 U.S.C. § 802
    (16), with Montana Code
    Annotated section 50-32-101(18). House also asserted that
    his 2013 cocaine conviction was not a controlled substance
    offense for two reasons. First, he argued that the Montana
    accountability statutes (i.e., Montana Code Annotated
    sections 45-2-302, 45-9-101 4) included aiding, abetting, and
    solicitation, which goes beyond the text of USSG
    § 4B1.2(b). Second, House appeared to make a scope-of-
    the-controlled-substance argument, though his contention in
    this regard is difficult to decipher.
    At sentencing, as to the 2007 marijuana conviction, the
    district court ruled: (1) 
    21 U.S.C. § 802
    (16) was amended in
    4
    At the time of House’s sentencing, Montana Code Annotated
    section 45-2-302(3) provided in relevant part: “[a] person is legally
    accountable for the conduct of another when: . . . either before or during
    the commission of an offense with the purpose to promote or facilitate
    the commission, the person solicits, aids, abets, agrees, or attempts to aid
    the other person in the planning or commission of the offense.” Montana
    Code Annotated section 45-9-101(1) stated: “a person commits the
    offense of criminal distribution of dangerous drugs if the person sells,
    barters, exchanges, gives away, or offers to sell, barter, exchange, or give
    away any dangerous drug[.]”
    12                UNITED STATES V. HOUSE
    2018 to exclude hemp from the federal definition of
    marijuana; (2) Montana Code Annotated section 50-32-
    101(18) makes no such distinction; but (3) “because this
    change did not take place until 2018, House was not subject
    to greater criminal liability in 2007 when he was convicted
    of his marijuana felony.” Additionally, the district court
    held that Montana Code Annotated section 50-32-101 was a
    “divisible statute” for purposes of applying the modified
    categorical approach, citing Coronado v. Holder, 
    759 F.3d 977
    , 984 (9th Cir. 2014). The court concluded that, although
    “a defendant, possessing solely hemp, could be convicted of
    criminal possession of marijuana under Montana law but not
    under federal law,” House had to “demonstrate more than a
    theoretical possibility that he faced greater criminal liability”
    to establish that his prior conviction was not a match, citing
    Duenas-Alvarez, 
    549 U.S. at 193
    . The court further stated
    that “House not only failed to provide any Montana cases
    imposing criminal liability for possession of hemp, but the
    judicially noticeable facts described in the underlying
    documents . . . establish that House plead[ed] guilty to
    possession of marijuana, a substance still included in the
    [Controlled Substances Act (“CSA”)], not possession of
    hemp.” The district court held that House’s 2007 marijuana
    conviction was a predicate offense for purposes of the
    sentencing enhancement under USSG § 2K2.1(a).
    As to the 2013 cocaine conviction, the district court
    rejected House’s first argument (i.e., that Montana’s
    accountability statute swept in more conduct than its federal
    counterpart) because that contention had been rebuffed in
    cases considering other similar state statutes, citing Crum,
    934 F.3d at 965–66. Turning to House’s second contention
    (i.e., whether Montana’s “accountability criminal
    distribution of dangerous drugs – cocaine – [was] a
    controlled substance offense”), the district court held:
    UNITED STATES V. HOUSE                    13
    (1) that reference should be made to federal regulatory
    definitions in making the comparison, and (2) in United
    States v. Holliday, No. CR 18-118-BLG-SPW, 
    2020 WL 814030
     (D. Mont. Feb. 19, 2020) (“Holliday I”), it had
    “recently determined the issue of whether Montana’s
    definition of cocaine fits the federal definition and
    determined that it is a categorical match.”
    The district court applied the USSG § 2K2.1(a)(2)
    enhancement, which set the base offense level at 24 and
    resulted in a Guidelines advisory range of 70 to 87 months’
    imprisonment. The Government recommended a 72-month
    sentence; House requested 27 to 33 months; and the court,
    after weighing the aggravating and mitigating
    circumstances, varied downward and sentenced him to
    48 months.
    After House filed his opening brief, we stayed this appeal
    pending the resolution of United States v. Bautista, No. 19-
    10448 (9th Cir. Feb. 26, 2021), because that case raised two
    issues that were germane here: (1) whether a marijuana
    conviction under Arizona Revised Statutes section 13-
    13405(A)(4) could constitute a controlled substance offense
    as defined in USSG § 4B1.2(b) following the removal of
    hemp in 2018 from the definition of marijuana in the CSA,
    and (2) whether, in comparing the defendant’s prior state
    conviction with the federal law, a court uses the CSA and
    corresponding Guidelines in existence at the time of the
    federal sentencing or, instead, the federal counterpart in
    existence at the time of the defendant’s underlying state
    conviction. Bautista held:
    At federal sentencing, the district judge was
    required to compare the elements of the state
    crime as they existed when Bautista was
    convicted of that offense to those of the crime
    14               UNITED STATES V. HOUSE
    as defined in federal law at the time of federal
    sentencing—that is, after the Agriculture
    Improvement Act removed hemp from the
    federal drug schedule. Because the federal
    CSA excludes hemp but Section 13-3405 of
    the Arizona Revised Statutes did not, the
    latter crime’s “greater breadth is evident from
    its text.” See [United States v.] Vidal,
    504 F.3d [1072,] 1082 [(9th Cir. 2007)].
    Bautista’s conviction is facially overbroad
    and not a categorical match for a “controlled
    substance offense,” and the district court
    erred in applying the recidivist sentencing
    enhancement for a controlled substance.
    Bautista, 989 F.3d at 705.
    Shortly thereafter, we reversed and remanded the district
    court’s decision in Holliday I. See United States v. Holliday,
    853 F. App’x 53 (9th Cir. 2021) (“Holliday II”). Relying on
    Bautista, Holliday II held that Montana’s definition of
    cocaine is broader than the federal counterpart. Id. at 54–55.
    III.   DISCUSSION
    We review de novo a district court’s interpretation of the
    Sentencing Guidelines, and its application of the Guidelines
    to the facts of the case generally for abuse of discretion. See
    United States v. Ayala-Nicanor, 
    659 F.3d 744
    , 746 (9th Cir.
    2011). “A district court abuses its discretion when it errs in
    its Guidelines calculation, imposes a sentence based on
    clearly erroneous facts, or imposes a substantively
    unreasonable sentence.” United States v. Burgos-Ortega,
    
    777 F.3d 1047
    , 1052 (9th Cir. 2015). Where a defendant
    proffers on appeal a sentencing issue that was not raised
    before the district court, we review for plain error. See
    UNITED STATES V. HOUSE                     15
    United States v. Depue, 
    912 F.3d 1227
    , 1232 (9th Cir. 2019)
    (en banc); Fed. R. Crim. P. 52(b).
    A. The 2007 Marijuana Conviction
    The Government admits that Montana’s definition of
    marijuana is substantially similar to the Arizona definition
    we considered in Bautista. The Government also “concedes
    that Bautista is controlling as to House’s first argument
    regarding his marijuana conviction,” and agrees with House
    that “this Court should remand for resentencing” without
    treating House’s marijuana conviction as a qualifying
    offense. We accept the government’s concession, reverse
    the district court’s application of the sentencing
    enhancement based on House’s 2007 marijuana conviction,
    and remand for resentencing. Cf. United States v. Halamek,
    
    5 F.4th 1081
    , 1091 (9th Cir. 2021) (accepting Government’s
    concession as to sentencing error and remanding for
    resentencing).
    B. The 2013 Cocaine Conviction
    As to whether his 2013 cocaine conviction is a qualifying
    prior controlled substance offense, House raises two
    arguments: (1) “the plain language of the § 4B1.2 guideline
    and commentary definition of a controlled substance offense
    does not include offers to engage in prohibited conduct,”
    while Montana’s accountability statutes do, rendering the
    latter     categorically     overbroad        (“accountability
    overbreadth”); and (2) Montana’s drug statute is
    categorically overbroad because its definition of cocaine
    includes substances that are either not set forth in the federal
    definition and/or are specifically excluded (“cocaine
    overbreadth”).
    16               UNITED STATES V. HOUSE
    1) Accountablity Overbreadth
    House points out that the conduct specifically delineated
    in USSG § 4B1.2(b) covers only “the manufacture, import,
    export, distribution, or dispensing of a controlled substance”
    or the possession thereof with such intent; whereas the
    Montana statutes (i.e., sections 45-2-302 and 45-9-101)
    include a person who “sells, barters, exchanges, gives away,
    or offers to sell, barter, exchange, or give away any
    dangerous drug.” House argues that Application Note 1 of
    the Commentary to § 4B1.2 improperly expands the
    prohibited conduct to “include the offenses of aiding and
    abetting, conspiring, and attempting to commit such
    offenses.”
    But as House recognized in both his sentencing
    memorandum to the district court and in his opening brief
    here, in Crum: (1) we “acknowledged that the commentary
    to § 4B1.2 does not mention solicitation, even though it
    expands the definition of ‘controlled substance offense’ to
    include aiding and abetting, conspiring, and attempting to
    commit such an offense,” and held that “the definition of
    ‘controlled substance offense’ in § 4B1.2 [nevertheless]
    encompasses solicitation offenses,” 934 F.3d at 965; and
    (2) we declined to reconsider our holding in Vea-Gonzales
    that Application Note 1 of the Commentary to § 4B1.2 is
    “perfectly consistent” with the text of § 4B1.2(b), Crum,
    934 F.3d at 966. Because we are bound by Crum, we hold
    that although Montana’s accountability statutes include
    offers to engage in prohibited conduct, they are not rendered
    categorically overbroad with respect to USSG §§ 4B1.2(b)
    and 2K2.1(a).
    UNITED STATES V. HOUSE                            17
    2) Cocaine Overbreadth
    As to House’s cocaine overbreadth contention, he raises
    new arguments on appeal that he did not present to the
    district court. In his opening brief, House asserts that “[t]he
    federal statutory definition of cocaine and the State of
    Montana statutory definition of cocaine differ, and the State
    of Montana’s definition is broader.” 5 But in his sentencing
    memorandum to the district court, House made different and
    more limited arguments.
    Because House did not raise his current arguments at
    sentencing, we review the district court’s sentencing
    calculation for plain error as to those contentions. See
    United States v. Wijegoonaratna, 
    922 F.3d 983
    , 991 (9th Cir.
    2019). The first two elements under that analysis are: (1) “an
    error that has not been intentionally relinquished or
    abandoned,” and (2) the error is plain—“that is to say, clear
    or obvious.” 6 Rosales-Mireles v. United States, 
    138 S. Ct. 5
    Montana Code Annotated section 50-32-224(1)(d) defines cocaine
    as including derivatives of cocaine. The CSA’s definition of cocaine at
    
    21 U.S.C. § 812
    (c) Schedule II(a)(4) excludes derivatives. The
    applicable federal regulation, 
    21 C.F.R. § 1308.12
    (b)(4), includes
    derivatives but excludes [123I]ioflupane, which is a cocaine derivative.
    Thus, the Montana statutory definition of cocaine is broader than both
    the CSA definition and the federal regulatory definition.
    6
    The third element of plain error review requires a showing that the
    error affects substantial rights of the defendant, which ordinarily means
    establishing “a reasonable probability that, but for the error, the outcome
    of the proceeding would have been different.” Molina-Martinez v.
    United States, 
    578 U.S. 189
    , 194 (2016) (internal quotation marks
    omitted). “In most cases a defendant who has shown that the district
    court mistakenly deemed applicable an incorrect, higher Guidelines
    range has demonstrated a reasonable probability of a different outcome.”
    
    Id. at 200
    .
    18                 UNITED STATES V. HOUSE
    1897, 1904 (2018) (quoting Molina-Martinez, 578 U.S.
    at 194). “An error cannot be plain where there is no
    controlling authority on point and where the most closely
    analogous precedent leads to conflicting results.”
    Wijegoonaratna, 922 F.3d at 991 (quoting United States v.
    De La Fuente, 
    353 F.3d 766
    , 769 (9th Cir. 2003)). The
    question is whether the district court plainly erred when it
    held that House’s 2013 cocaine conviction pursuant to
    Montana Code Annotated sections 45-9-101 and 50-32-
    224(1)(d) was a controlled substance offense as set forth in
    USSG § 4B1.2(b). We conclude that it did not.
    First, applying the categorical approach, the court must
    determine whether the Montana statutory definition of
    cocaine is a match with federal law. As we have explained,
    under federal law, cocaine is defined by both statute and
    regulation, and the Montana definition is broader than either
    federal definition. 
    21 U.S.C. § 812
    (c) Schedule II(a)(4) does
    not expressly include cocaine derivatives within its
    definition (although it does expressly reference ecgonine
    derivatives).     See footnote 5, supra.         
    21 C.F.R. § 1308.12
    (b)(4) expressly includes cocaine (and ecgonine)
    derivatives, but also expressly excludes [123I]ioflupane.
    Montana Code Annotated section 50-32-224(1)(d) expressly
    includes cocaine derivatives but does not expressly exclude
    or mention [123I]ioflupane.
    When the district court reached its decision that a
    cocaine conviction under Montana Code Annotated sections
    45-9-101 and 50-32-224(1)(d) could constitute a controlled
    substance offense under § 4B1.2(b), there was no (and there
    still is no) binding precedent to the contrary. 7 House was
    7
    Holliday II—which held that the Montana schedules as to cocaine
    “are facially overbroad when compared with both the federal statutory
    UNITED STATES V. HOUSE                          19
    sentenced on August 5, 2020. At that time, the only case to
    have considered the issue was the unpublished decision in
    United States v. Lasalle, 758 F. App’x 410 (9th Cir. 2019),
    which held that it was not plain error for a court to look to
    the federal regulatory definition of cocaine (which during the
    relevant period was purportedly a categorical match with the
    Montana statute) and concluded that the defendant’s prior
    conviction under Montana Code Annotated sections 45-9-
    101 and 50-32-224(1)(d) fell within § 4B1.2(b). See id. at
    411–12.
    Second, certain of the grounds for the district court’s
    rulings were not rejected in binding precedent until after its
    sentencing decision. For example, the district court had (as
    had many other federal courts) compared the elements of the
    state conviction with the federal law that existed at the time
    of the state sentencing, rather than the federal statutes and
    guidelines that existed at the time of the federal sentencing.
    See, e.g., Martinez v. Attorney General, 
    906 F.3d 281
    , 287
    (3d Cir. 2018) (holding that, although 
    21 C.F.R. § 1308.12
    (b)(4) currently expressly exempts [123I]ioflupane
    from the list of schedule II substances, the court uses the list
    at the time of the defendant’s prior state conviction, which
    had not yet added that exclusion). Bautista overturned that
    approach and held, “In imposing a sentence, the district court
    must consider the sentencing guidelines range ‘that . . . [is]
    in effect on the date the defendant is sentenced.’ 
    18 U.S.C. § 3553
    (a)(4)(A)(ii).” 989 F.3d at 703 (alterations in
    original).
    schedules and the federal regulatory schedules” and, thus, the cocaine
    conviction therein was not a controlled substance offense—was issued
    on March 3, 2021 and was unpublished. 853 F. App’x at 54 n.1.
    20               UNITED STATES V. HOUSE
    Accordingly, the district court did not commit plain error
    with respect to the cocaine overbreadth issue when it held
    that House’s 2013 cocaine conviction was a controlled
    substance offense as set forth in USSG § 4B1.2(b).
    IV.    CONCLUSION
    We reverse the district court’s sentencing enhancement
    insofar as it rested on House’s 2007 marijuana conviction
    and remand for resentencing. But the district court’s
    determination that House’s 2013 cocaine conviction was a
    qualifying prior controlled substance offense for purposes of
    the § 4B1.2(b) sentencing enhancement was not plainly
    erroneous.
    AFFIRMED IN PART, REVERSED IN PART, AND
    REMANDED FOR RESENTENCING.
    GRABER, Circuit Judge, concurring:
    I concur in the per curiam opinion but write separately to
    explain my views concerning overbroad state statutes. In my
    view, we have distinguished between overbreadth that is
    “evident” from the statute’s text and overbreadth that is not
    “evident” from the text.
    The general rule is that a state law cannot be considered
    broader than a federal law if the state law’s breadth is
    imagined or theoretical; in other words, the overbreadth
    must be real. See Gonzales v. Duenas-Alvarez, 
    549 U.S. 183
    , 193 (2007) (“[T]o find that a state statute creates a
    crime outside the generic definition of a listed crime in a
    federal statute requires more than the application of legal
    imagination to a state statute’s language. It requires a
    UNITED STATES V. HOUSE                       21
    realistic probability, not a theoretical possibility, that the
    State would apply its statute to conduct that falls outside the
    generic definition of a crime.” (emphasis added)).
    But we have applied that rule in two ways. “[W]hen the
    state statute’s greater breadth is evident from its text, a
    defendant may rely on the statutory language to establish the
    statute as overly inclusive.” United States v. Vidal, 
    504 F.3d 1072
    , 1082 (9th Cir. 2007) (en banc) (internal citations and
    quotation marks omitted) (emphasis added), abrogated on
    other grounds as recognized in United States v. Bautista,
    
    989 F.3d 698
    , 704 (9th Cir. 2021); see also United States v.
    Grisel, 
    488 F.3d 844
    , 847 (9th Cir. 2007) (en banc) (“[When
    a] state statute explicitly defines a crime more broadly than
    the generic definition, no legal imagination[] is required to
    hold that a realistic probability exists that the state will apply
    its statute to conduct that falls outside the generic definition
    of the crime. The state statute’s greater breadth is evident
    from its text.” (internal citations and quotation marks
    omitted) (emphasis added)), abrogated on other grounds by
    United States v. Stitt, 
    139 S. Ct. 399
     (2018).
    When the state law’s overbreadth is not “evident from its
    text,” the party arguing for overbreadth must find a relevant
    case establishing a “realistic probability” of overbroad
    application. See Vidal, 
    504 F.3d at 1082
     (“In the absence of
    any case in which the state courts in fact did apply the statute
    in the special (nongeneric) manner, this argument failed for
    lack of evidence that such an application of the state statute
    was a realistic probability [and] not a theoretical
    possibility.”(internal citations and quotation marks omitted)
    (emphasis added)).
    It is under that framework that we decided United States
    v. Bautista, 
    989 F.3d 698
     (9th Cir. 2021). In Bautista, we
    held that the state law was overbroad. The state law
    22                UNITED STATES V. HOUSE
    criminalized both attempted transportation of hemp and
    attempted transportation of marijuana; but the federal law
    did not criminalize hemp at all. Thus, because the state law’s
    greater breadth was evident from the text, the state law barred
    more than the federal law. 
    Id. at 705
    . For that reason,
    Bautista rested on the correct proposition that the state law’s
    “greater breadth is evident from its text.” 
    Id.
     (quoting Vidal,
    
    504 F.3d at 1082
    ).
    In sum, Duenas-Alvarez expressed the general rule: a
    state law’s breadth in categorical-approach cases always
    must be realistically probable and cannot be theoretical or
    imagined. 
    549 U.S. at 193
    . We have construed facially
    overbroad statutes as meeting that bar whenever the state
    statute’s overbreadth is “evident from its text.” When a
    federal statute contains an express exception but the parallel
    state statute contains no such exception, the difference
    between them is “evident” from the text. In that situation,
    no evidentiary examples are required to demonstrate a
    realistic probability of prosecution. Put another way, when
    a state law prohibits “X” and a federal law prohibits “X
    except Y is not included,” it is “evident” from the text that
    the state statute is overbroad, so it is not necessary to find a
    case demonstrating that the state prosecutes “Y.”
    CHRISTEN, Circuit Judge, concurring:
    I
    The government concedes that House’s prior marijuana
    conviction should not count as a “controlled substance
    offense” in the calculation of House’s sentencing guidelines
    range, and I agree that the district court did not plainly err in
    determining that his prior cocaine-related offense did
    UNITED STATES V. HOUSE                        23
    qualify. But, shortly after the district court ruled, our court
    suggested in an unpublished decision that Montana’s
    definition of cocaine is categorically overbroad. See United
    States v. Holliday, 853 F. App’x 53 (9th Cir. 2021)
    (“Holliday II”). In my view, Holliday II’s categorical
    analysis skipped an important step by taking the holdings
    from United States v. Grisel 1 and United States v. Bautista 2
    out of context.
    I write separately because the complicated categorical
    approach has proven inordinately time consuming—for
    district courts and for circuit courts—and our court’s prior
    consideration of Montana’s cocaine statute may result in
    confusion regarding the correct Taylor 3 methodology. The
    Holliday II majority concluded that: (1) Montana’s
    definition of cocaine is “facially overbroad” because it
    includes a substance expressly excluded from the federal
    counterpart; and (2) the “varieties of cocaine” included in
    Montana’s drug schedules are “alternative means of
    committing a single crime, not alternative elements of
    separate crimes.” 853 F. App’x at 54–55. The Holliday II
    majority stopped short of considering whether there is “a
    realistic probability, not a theoretical possibility,” 4 that
    Montana would apply its definition of cocaine to conduct
    that falls outside the federal definition. See Holliday II,
    853 F. App’x at 54–55. Rather than engaging in this inquiry,
    Holliday II prematurely ended its analysis after concluding

    Id.
     (quoting Bautista, 989 F.3d at 705).
    II
    The first step in the Taylor categorical approach requires
    us to compare the elements of the state statute with those in
    the federal counterpart to determine whether the state statute
    sweeps in more conduct or, as in House’s case, criminalizes
    more controlled substances, than the federal definition. See
    United States v. Martinez-Lopez, 
    864 F.3d 1034
    , 1038 (9th
    Cir. 2017). Even when there is a mismatch between the state
    and federal statutes, Duenas-Alvarez teaches that to find the
    state statute categorically broader than its federal counterpart
    “requires a realistic probability, not a theoretical possibility,
    that the State would apply its statute to conduct that falls
    outside the generic definition of a crime.” 
    549 U.S. at 193
    .
    Soon after the Supreme Court decided Duenas-Alvarez,
    our en banc court in Grisel considered whether Oregon’s
    burglary statute was a categorical match to the generic
    offense. The Supreme Court had defined the federal offense
    to require unlawful entry into, or remaining in, “a building
    or structure[] with intent to commit a crime.” Grisel,
    
    488 F.3d at 848
     (quoting Taylor, 
    495 U.S. at 599
    ). Oregon’s
    burglary statute starkly differed from the federal offense
    because it defined “building” to include “any booth, vehicle,
    boat, aircraft or other structure adapted for overnight
    accommodation of persons or for carrying on business
    therein.” Id. at 850 (quoting 
    Or. Rev. Stat. § 164.205
    (1)).
    Grisel went on to recognize that the Oregon legislature had
    “consciously defined” burglary to be broader than the federal
    definition “by extending the statute to non-buildings,” 
    id.,
    and cited Oregon case law that pinpointed the legislature’s
    express intent to sweep in more conduct, 
    id.
     at 850 n.4.
    Under those circumstances—and consistent with Duenas-
    UNITED STATES V. HOUSE                     25
    Alvarez—we concluded “[t]he state statute’s greater breadth
    is evident from its text,” and “no ‘legal imagination’ is
    required to hold that a realistic probability exists that
    [Oregon would] apply its statute to conduct that falls outside
    the generic definition.” 
    Id. at 850
     (citation omitted) (quoting
    Duenas-Alvarez, 
    549 U.S. at 193
    ). Grisel does not stand for
    the proposition that Taylor’s categorical inquiry ends simply
    because a textual comparison of a state statute’s elements
    shows the state statute sweeps more broadly than its federal
    counterpart.
    Since Grisel, we have recognized a subset of cases
    addressing state statutes that only impliedly criminalize more
    conduct than their federal counterparts. Rather than
    including more conduct or controlled substances, these
    statutes do not contain an exclusion that appears in the
    corresponding federal law. See, e.g., United States v. Vega-
    Ortiz, 
    822 F.3d 1031
    , 1035–36 (9th Cir. 2016); United States
    v. Burgos-Ortega, 
    777 F.3d 1047
    , 1054–55 (9th Cir. 2015).
    Cases involving statutes of this type are particularly relevant
    to House’s appeal because, like Montana’s definition of
    cocaine, they involve statutes that are silent about certain
    substances expressly excluded from the federal definition of
    a controlled substance. See, e.g., Vega-Ortiz, 822 F.3d
    at 1036     (describing      California’s      definition    of
    methamphetamine as impliedly overbroad even though it
    does “not expressly include conduct not covered by the
    generic offense, but rather is silent as to the existence of a
    parallel [L-meth] exception.’” (alteration in original)
    (emphasis added) (quoting Burgos-Ortega, 777 F.3d
    at 1055)).
    26                     UNITED STATES V. HOUSE
    Where a state statute is only impliedly overbroad, our
    case law 5 requires that defendants identify “any case where
    a defendant was in fact prosecuted or convicted” for the
    impliedly included substance or conduct that the federal
    definition expressly excludes. Burgos-Ortega, 777 F.3d
    at 1054–55. This step determines whether the “theoretical
    possibility[] that the State would apply its statute to conduct
    that falls outside the generic definition” is a realistic one, as
    the Supreme Court required in Duenas-Alvarez. 
    549 U.S. at 193
    .
    Two of our cases are illustrative. Burgos-Ortega
    involved a Washington state statute that criminalized, among
    other things, distribution of a controlled substance. See
    777 F.3d at 1052. Washington’s statute did not except
    “administering” from the definition of “distribution,” but the
    federal counterpart did. Id. We rejected Burgos-Ortega’s
    argument that the state statute was “overbroad on its face”
    merely because the state statute did not “expressly include
    conduct not covered by the generic [federal] offense, but
    rather [was] silent as to the existence of a parallel
    administering exception.” Id. at 1055. Burgos-Ortega could
    not point “to any case where a defendant was in fact
    prosecuted or convicted for administering a drug under [the
    state] statute,” and we upheld the district court’s sentencing
    enhancement. Id.
    A year later, we considered California’s definition of
    methamphetamine in Vega-Ortiz. We first observed that
    California’s definition was silent as to “L-meth,” a substance
    the federal definition expressly excluded. See Vega-Ortiz,
    822 F.3d at 1035–36. Citing Burgos-Ortega and Duenas-
    Alvarez, we held that “to succeed on his claim[,] Vega-Ortiz
    5
    Holliday II was not published. See 853 F. App’x at 53.
    UNITED STATES V. HOUSE                           27
    would need to show a ‘realistic probability’ that he would be
    prosecuted under [the state statute] for possession of the
    [federally] excluded product containing L-meth.” Id.
    at 1036.
    Like House’s case, United States v. Holliday, 853 F.
    App’x 53 (9th Cir. 2021) (“Holliday II”), concerned
    Montana’s definition of cocaine. Holliday II explained that
    Montana’s statute impliedly includes “ioflupane” because it
    makes no mention of that substance and ioflupane is
    expressly excluded from the federal definition. Id. at 54. At
    step one, Holliday II recognized the textual mismatch
    between the state and federal definitions. Id. So far, so
    good. But after the judicially noticeable documents showed
    only that Holliday’s prior conviction was for selling
    “cocaine,” the majority tripped up by concluding it was
    “evident from [the] text” of the Montana statute that the state
    definition of cocaine is “facially overbroad,” and ending its
    analysis. 6 Id. at 54–55 (quoting Bautista, 989 F.3d at 705). 7
    6
    Judge Watford’s dissent in Holliday II recognized the disconnect
    between the Holliday II majority’s conclusion and our precedent. His
    dissent reasoned that Montana’s cocaine statute is the same type that was
    at issue in Vega-Ortiz and Burgos-Ortega and that Montana’s definition
    is overbroad “only if [a defendant shows] there is a realistic probability
    of prosecution under Montana law for distribution of Ioflupane.” 853 F.
    App’x at 56.
    7
    The Holliday II majority may have relied on a sentence from
    Lopez-Aguilar v. Barr, 
    948 F.3d 1143
     (9th Cir. 2020), which, if read
    literally, suggests “the relative likelihood” that a state would apply its
    statute to “nongeneric conduct is immaterial,” Holliday II, 853 F. App’x
    at 55. That reading would be plainly inconsistent with Duenas-Alvarez.
    Lopez-Aguilar and the case it cited, United States v. Valdivia-Flores,
    
    876 F.3d 1201
     (9th Cir. 2017), involved statutes that were akin to the one
    at issue in Grisel, where “no ‘legal imagination’ [was] required” to
    28                   UNITED STATES V. HOUSE
    To be sure, there are statutes like the burglary statute at
    issue in Grisel where courts will have occasion to decide a
    state law is so starkly overbroad that “no legal imagination
    is required to hold that a realistic probability exists” the state
    would apply its definition to a substance (or conduct) falling
    outside of the generic definition. 
    488 F.3d at 850
     (citations
    omitted). But Grisel only required our court to recognize
    that Oregon would apply its burglary statute to the unlawful
    entry into vehicles, boats, or aircraft where the legislature
    had expressly defined “building” to include vehicles, boats,
    and aircraft. See 
    488 F.3d at 850
    . Given that circumstance,
    it was indeed evident from the text of the statute that Oregon
    would actually prosecute, as burglary, the unlawful entry
    into vehicles, boats, or aircraft. Controlled substances
    statutes are much less intuitive. Indeed, absent a degree in
    pharmacology, it is doubtful there will be many judges in a
    position to accurately predict from the text of a controlled
    substances statute that a state would prosecute a particular
    controlled substance. Cf. United States v. Rodriguez-
    Gamboa, 
    972 F.3d 1148
    , 1151–53 (9th Cir. 2020)
    (concluding California’s definition of methamphetamine
    was not categorically overbroad, even though it included
    “geometric isomers” and the federal definition did not,
    because “unrebutted expert testimony” demonstrated
    “geometric isomers of methamphetamine do not exist,” so
    there was “no possibility of application of the state statute to
    nongeneric conduct” (internal quotation marks omitted)).
    recognize a “realistic probability” that the state would apply its statute in
    the nongeneric manner, 
    id. at 1208
     (quoting Grisel, 
    488 F.3d at 850
    )
    (distinguishing the federal “mens rea requirement of specific intent” and
    Washington’s requirement of “mere[] knowledge”); Lopez-Aguilar,
    948 F.3d at 1146–47 (recognizing Oregon’s definition of third-degree
    robbery allowed consensual takings by deception whereas the federal
    definition was limited to nonconsensual takings).
    UNITED STATES V. HOUSE                     29
    This is why, even when a state statute sweeps in more
    conduct or controlled substances, the complete Taylor
    analysis includes the reality check the Supreme Court
    introduced in Duenas-Alvarez to determine whether there is
    a realistic probability a state would prosecute the possession
    or distribution of a particular controlled substance. This step
    can be particularly illuminating in cases involving impliedly
    overbroad statutes. Expert testimony might establish that a
    realistic probability does not exist; or, where a substance has
    been removed from the federal schedule, the rationale relied
    on by the federal government may be informative.
    One member of our panel would decide that the
    mismatch between Montana’s definition of cocaine and the
    federal definition is “evident from the text” and end the
    analysis there. In my view, there are two problems with this
    approach. First, the nature of the categorical inquiry is such
    that any mismatch between the state and federal elements
    will always be evident from the text because the categorical
    approach requires that we identify the elements of the
    offense from the text of the state statute and compare them
    to those in the federal counterpart. Second, Supreme Court
    precedent requires that we consider whether there is a
    realistic probability the state would actually prosecute the
    overly broad portion of the statute. See Duenas-Alvarez,
    
    549 U.S. at 193
    . My colleague treats this as one step, but in
    my view it is necessarily two because the textual comparison
    tells us only whether a state statute is overbroad; it tells us
    nothing about whether the state would realistically prosecute
    the substance (or conduct) included in the state statute.
    A comparison of the elements of Montana’s statute with
    those in the federal definition of cocaine shows that
    Montana’s statute is impliedly broader because it does not
    exclude ioflupane. Step two requires consideration of
    30                 UNITED STATES V. HOUSE
    whether Montana would actually prosecute the distribution
    of ioflupane, a substance the Food and Drug Administration
    excepted from the federal definition because it is the active
    ingredient in a product that “itself presents no practical
    possibility of abuse, misuse, diversion or clandestine
    production.” 8
    III
    I agree that the plain error standard applies to our review
    of the district court’s analysis of House’s 2013 cocaine
    conviction, and the parties agreed that the district court’s
    application of a sentencing enhancement based on House’s
    2007 marijuana conviction should be reversed. I therefore
    concur in the court’s per curiam opinion.

    I concur in the per curiam opinion but write separately to

    context of the applicable Montana statute, i.e., 
    Mont. Code Ann. § 50-32-224
    (1)(d). The area is hopelessly confused,
    and I suggest a modest solution. A brief overview of the law

    II. An Issue Stemming from the Varying Federal
    Delineations of Cocaine
    For purposes of the categorical/modified categorical
    analysis, the Ninth Circuit has interpreted the term
    “controlled substance” as used in USSG §§ 2K2.1(a) and
    4B1.2(b) “to mean a substance listed in the Controlled
    Substances Act (‘CSA’), 
    21 U.S.C. § 801
     et seq.” United
    States v. Bautista, 
    989 F.3d 698
    , 702 (9th Cir. 2021).
    “[C]onstruing the phrase in the Guidelines to refer to the
    definition of ‘controlled substance’ in the CSA—rather than
    to the varying definitions of ‘controlled substance’ in the
    different states—furthers uniform application of federal
    sentencing law, thus serving the stated goals of both the
    Guidelines and the categorical approach.” 1 
    Id.
     (citing to
    United States v. Leal-Vega, 
    680 F.3d 1160
    , 1167 (9th Cir.
    2012), and Taylor v. United States, 
    495 U.S. 575
    , 589
    (1990)).
    1
    The goal of achieving a uniform application of federal sentencing
    law in this area is initially vitiated by fact that there is a split amongst the
    federal circuits as to whether the definition of “controlled substance” is
    limited to federal law (i.e., the substances listed in the CSA) or whether
    the definition is based on relevant state law. See Guerrant v. United
    States, 
    142 S. Ct. 640
     (2022) (Sotomayor, J., concurring in denial of
    certiorari) (observing that the Second and Ninth Circuits “have turned to
    federal law to define the term”; the First and Fifth Circuits “have not
    directly resolved the question, but have indicated agreement with that
    approach”; the Fourth, Seventh, Eighth and Tenth Circuits “define[]
    what qualifies as a ‘controlled substance’ based on relevant state law”;
    and the Sixth and Eleventh Circuits “have issued internally inconsistent
    decisions on the question.”). 
    Id. at 640
     (citations omitted).
    32               UNITED STATES V. HOUSE
    In determining the federal demarcation of a particular
    controlled substance, one initially examines the CSA—i.e.,
    21 U.S.C. Chapter 13, Subchapter I. The CSA defines a
    “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 [i.e., 
    21 U.S.C. § 812
    ].”
    
    21 U.S.C. § 802
    (6). While various drugs are identified and
    listed in the schedules, the actual definitions and/or
    descriptions of the substances are delineated in a number of
    different locations within the CSA and not just within the
    schedules. See, e.g., 
    21 U.S.C. § 812
    (c), Schedule I(c)(10)
    (listing “marihuana” as a Schedule I drug); 
    21 U.S.C. § 802
    (16) (containing a definition of “[t]he term
    ‘marihuana’”).
    Additionally, 
    21 U.S.C. § 811
    (a) allows the United
    States Attorney General, pursuant to the rulemaking
    provisions of the Administrative Procedure Act (
    5 U.S.C. §§ 551
    –59), to “add to such a schedule or transfer between
    such schedules any drug or other substance” or “remove any
    drug or other substance from the schedules . . . .” See also
    
    21 U.S.C. § 812
    (c) (“Schedules I, II, III, IV, and V shall,
    unless and until amended pursuant to section 811 of this title
    [
    21 U.S.C. § 811
    ], consist of the following drugs or other
    substances, by whatever official name, common or usual
    name, chemical name, or brand name designated . . . .”
    (emphasis added, footnote omitted)).             Therefore, in
    determining whether a particular drug or its variants are
    designated as federal controlled substances, one must also
    review the relevant regulations promulgated by the Attorney
    General. See 
    21 C.F.R. § 1308.02
     (“Any term contained in
    this part shall have the definition set forth in section 102 of
    the Act (21 U.S.C. 802) or part 1300 of this chapter.”). The
    Ninth Circuit has, on occasion, relied upon the federal
    regulatory definitions of controlled substances when
    UNITED STATES V. HOUSE                          33
    conducting a categorical analysis under Taylor. See, e.g.,
    Coronado v. Holder, 
    759 F.3d 977
    , 988 Appendix 1 (9th Cir.
    2014) (In engaging in the categorical analysis to determine
    whether there was a match as to California law and the CSA,
    the panel made comparisons between the state statutes and
    the corresponding federal regulations in 
    21 C.F.R. §§ 1308.11
    –1308.15.).
    Turning to the various definitions of cocaine involved in
    this case, it would appear that the Montana statutory
    definition of cocaine is broader than both the CSA definition
    (because the Montana statute includes derivatives of cocaine
    whereas the CSA does not), and the federal regulatory
    definition (because it does not specifically exclude
    [123I]ioflupane 2—which is a cocaine derivative—whereas
    
    21 C.F.R. § 1308.12
    (b)(4) does). 3 However, it would also

    equivalent or identical with any of these substances,
    except that these substances do not include
    decocainized coca leaves or extraction of coca leaves,
    34                   UNITED STATES V. HOUSE
    appear that the CSA and the federal regulatory definitions of
    cocaine are likewise not a categorical match with each other.
    
    21 U.S.C. § 812
    (c) Schedule II(a)(4) does not expressly
    include cocaine derivatives within its definition (although it
    does expressly reference ecgonine derivatives) nor does it
    expressly exclude [123I]ioflupane.               21 C.F.R.
    which extractions do not contain cocaine or ecgonine
    ....
    The CSA at 
    21 U.S.C. § 812
    (c) Schedule II(a)(4) includes:
    coca leaves, except coca leaves and extracts of coca
    leaves from which cocaine, ecgonine, and derivatives
    of ecgonine or their salts have been removed; cocaine,
    its salts, optical and geometric isomers, and salts of
    isomers; ecgonine, its derivatives, their salts, isomers,
    and salts of isomers; or any compound, mixture, or
    preparation which contains any quantity of any of the
    substances referred to in this paragraph.
    The applicable federal regulation, i.e., 
    21 C.F.R. § 1308.12
    (b)(4), states:
    Coca leaves (9040) and any salt, compound, derivative
    or preparation of coca leaves (including cocaine
    (9041) and ecgonine (9180) and their salts, isomers,
    derivatives and salts of isomers and derivatives), and
    any salt, compound, derivative, or preparation thereof
    which is chemically equivalent or identical with any of
    these substances, except that the substances shall not
    include:
    (i) Decocainized coca leaves or extraction of
    coca leaves, which extractions do not contain
    cocaine or ecgonine; or
    (ii) [123I]ioflupane.
    UNITED STATES V. HOUSE                       35
    § 1308.12(b)(4) expressly includes cocaine (and ecgonine)
    derivatives, but also expressly excludes [123I]ioflupane.
    The Ninth Circuit has not yet determined whether “the
    definition of cocaine in the CSA, rather than the definition
    in the corresponding regulation, should be the controlling
    definition for the purposes of the Taylor analysis.” United
    States v. Lasalle, 785 F. App’x 410, 412 (9th Cir. 2019); see
    also United States v. Holliday, 853 F. App’x 53, 54 n.1 (9th
    Cir. 2021) (noting the difference but not deciding whether
    the “federal statutory schedules” or the “federal regulatory
    schedules” are the “appropriate comparator” in regards to
    “cocaine-related substances.”). There is also no precedent
    as to what a court should do in the context of the categorical
    analysis where the definition of a controlled substance in the
    CSA differs from the definition in the corresponding federal
    regulation.
    In regards to cocaine, because the appropriate categorical
    analysis under Taylor will differ depending upon whether
    one compares the Montana statute with the CSA (where the
    overbreadth rests on 
    Mont. Code Ann. § 50-32-224
    (1)(d)’s
    inclusion of cocaine derivatives in its definition) versus
    comparing the Montana statute with 
    21 C.F.R. § 1308.12
    (b)(4) (where the overbreadth arises from the
    latter’s express exclusion of [123I]ioflupane), it is essential to
    select the appropriate comparator at the first step of the
    analysis. Given that: (1) the schedules of controlled
    substances in the CSA are to be updated annually, see
    
    21 U.S.C. § 812
    (a); Coronado, 759 F.3d at 983; (2) the
    “drugs and other substances” designated in the schedules
    remain there “unless and until amended pursuant to section
    811,” 
    21 U.S.C. § 812
    (c); and (3) 
    21 U.S.C. § 811
    (a)
    authorizes the Attorney General to add, remove or transfer
    substances between the schedules, I would hold that—where
    36                UNITED STATES V. HOUSE
    there is a difference in the delineation of a substance between
    the CSA and a subsequent regulation promulgated by the
    Attorney General—the latter controls for purposes of the
    categorical analysis.
    III. The Appropriate Procedure Where There Is
    Overbreadth as Between the Federal Definition of a
    Controlled Substance and the State Definition
    In their concurrences, Judges Graber and Christen assert
    that, where there is overbreadth between the federal and state
    definitions of a controlled substance, the correct procedure
    (regarding whether and when one should consider the
    realistic probability factor from Gonzales v. Duenas-
    Alvarez, 
    549 U.S. 183
    , 193 (2007)) is dependent upon
    whether one characterizes the overbreadth as being
    “explicit/evident” versus “implied/implicit.” I find that step
    ambiguous and unnecessary in regards to the differing
    articulations of cocaine in this case and would simply apply
    the Duenas-Alvarez realistic probability factor regardless.
    First, where the issue arises from the differing
    delineations of a controlled substance in statutes and/or
    regulations, one is not engaged in the comparison of “the
    elements of the crime of conviction with the elements of the
    ‘generic’ version of the listed offense—i.e., the offense as
    commonly understood.” Mathis v. United States, 
    136 S. Ct. 2243
    , 2247 (2016). Thus, the reasoning and holdings of
    cases such as United States v. Grisel, 
    488 F.3d 844
    , 847 (9th
    Cir. 2007) (en banc), abrogated on other grounds by United
    States v. Stitt, 
    139 S. Ct. 399
     (2018)—which employ the
    notion of a state law’s overbreadth being evident or explicit
    from its text in that process—are not applicable here.
    Second, in the context of comparing 
    Mont. Code Ann. § 50-32-224
    (1)(d) with 
    21 C.F.R. § 1308.12
    (b)(4), the
    UNITED STATES V. HOUSE                   37
    resulting overbreadth arises solely because in 2015 the
    Attorney General expressly excepted [123I]ioflupane from
    the regulatory delineation of cocaine. It is unclear on what
    basis one would characterize that particular overbreadth as
    being “evident,” “explicit,” “implied,” or “implicit.”
    Third, the Attorney General has an annual opportunity to
    modify the definition of a particular drug in the CSA’s
    schedules of controlled substances.         The unintended
    consequence of the exercise of this authority may be the
    wholesale exclusion of prior convictions that were based
    upon the affected drug for purposes of USSG § 4B1.2(b),
    unless state legislatures immediately amend their definitions
    of the substance to conform with the new federal regulatory
    definition. The present case typifies the problem. There
    previously was a categorical match as to cocaine between the
    federal regulation and the Montana statute. However, in
    2015, the Attorney General specifically excluded from that
    substance’s description “[123I]ioflupane”—the active
    pharmaceutical ingredient in a “single-dose, injectable
    diagnostic radiopharmaceutical for use in hospital settings
    with specialized gamma cameras” for treatment of patients
    with Parkinson disease where the drug “presents no practical
    possibility of abuse, misuse, diversion or clandestine
    production.”      
    80 Fed. Reg. 31522
    -23.        The Taylor
    categorical analysis’s goal of uniform application of federal
    sentencing law would not be furthered in any way by a
    finding that prior state cocaine convictions are no longer
    “controlled substance offenses” merely because of the
    discrepancy created by 2015 amendment to the regulation.
    Fourth, the Ninth Circuit has applied the Duenas-Alvarez
    realistic probability criterion in a similar situation where
    there was overbreadth between a state statutory definition of
    a drug and its federal analogue. United States v. Rodriguez-
    38               UNITED STATES V. HOUSE
    Gamboa, 
    946 F.3d 548
     (9th Cir. 2019) (“Rodriguez-Gamboa
    I”), involved a state statute (i.e., 
    Cal. Health & Safety Code § 11378
    ) which prohibited possessing for sale any controlled
    substance that was “specified” in § 11055(d), which
    included “[m]ethamphetamine, its salts, isomers, and salts of
    its isomers.” 
    Cal. Health & Safety Code § 11033
     provided
    that “the term ‘isomer’ includes optical and geometrical
    (diastereometric) isomers.” 
    Id.
     at 551–52. The federal
    statute also prohibited the possession for sale of
    “methamphetamine, including its salts, isomers, and salts of
    isomers,” but stated that the “term ‘isomer’ means the optical
    isomer.”       
    Id.
     (referencing 
    21 U.S.C. §§ 802
    (14),
    812 Schedule II(c), Schedule III(a)(3)). Citing to the state
    statutes’    inclusion of         geometrical     isomers   of
    methamphetamine which were not included in the federal
    statute, the defendant-appellee argued that the “textual
    distinction” ended the categorical analysis because the “state
    statute’s greater breadth is evident from its text” and hence
    “no ‘legal imagination’ is required to hold that a realistic
    probability exists that the state will apply its statute to
    conduct that falls outside the generic definition of the
    crime.” 
    Id. at 552
     (quoting Grisel, 
    488 F.3d at 850
    ). In
    response, the Government asserted that “the geometric
    isomer of methamphetamine does not exist” and, citing to
    Duenas-Alvarez, argued that, despite the difference in the
    statutes’ respective texts, it was still necessary to show “a
    realistic probability, not a theoretical possibility, that the
    State would apply its statute to [the alleged] conduct . . . .”
    
    Id.
     The panel in Rodriguez-Gamboa I agreed; but, because
    the district court had not resolved the factual issue of the
    existence of geometric isomers of methamphetamine, the
    matter was remanded for that limited purpose. 
    Id.
     at 552–
    53.
    UNITED STATES V. HOUSE                     39
    Upon the return of case to the circuit, the panel made
    reference to the Supreme Court’s indication in Moncrieffe v.
    Holder, 
    569 U.S. 184
     (2013), that Duenas-Alvarez’s
    reasonable probability criterion should be applied even
    where there is a readily apparent overbreadth between the
    federal statute and its state counterpart. See United States v.
    Rodriguez-Gamboa, 
    972 F.3d 1148
    , 1153–54 (9th Cir.
    2019). As stated in Moncrieffe:
    Finally, the Government suggests that our
    holding will frustrate the enforcement of
    other aggravated felony provisions, like
    §1101(a)(43)(C), which refers to a federal
    firearms statute that contains an exception for
    “antique firearm[s],” 
    18 U.S.C. §921
    (a)(3).
    The Government fears that a conviction
    under any state firearms law that lacks such
    an exception will be deemed to fail the
    categorical inquiry. But Duenas-Alvarez
    requires that there be “a realistic probability,
    not a theoretical possibility, that the State
    would apply its statute to conduct that falls
    outside the generic definition of a crime.”
    
    549 U.S., at 193
    . To defeat the categorical
    comparison in this manner, a noncitizen
    would have to demonstrate that the State
    actually prosecutes the relevant offense in
    cases involving antique firearms.
    
    569 U.S. at
    205–06.
    In conclusion, I would apply the Duenas-Alvarez’s
    reasonable probability factor (as further considered in
    Moncrieffe) in initially determining whether the definition of
    cocaine in 
    Mont. Code Ann. § 50-32-224
    (1)(d) is a
    40            UNITED STATES V. HOUSE
    categorical match with its delineation in 
    21 C.F.R. § 1308.12
    (b)(4).
