    KAYATTA, Circuit Judge.           Petitioners -- botany professor
    Dr. Lyle Craker and clinical research company Scottsdale Research
    Institute (SRI)       --   challenge a rule promulgated by the Drug
    Enforcement Administration (DEA) that sets the framework through
    which    applicants    may    register       to   lawfully    manufacture   and
    cultivate cannabis for research purposes.                    For the following
    reasons, we deny their petitions for review.
    I.
    A.
    We begin by laying out the statutory and administrative
    scheme   that    governs    the    registration     of   prospective    cannabis
    growers.     The Controlled Substances Act (CSA), 
    21 U.S.C. § 801
     et
    seq.,    requires     "[e]very      person    who    manufactures . . .      any
    controlled      substance"    to    first     register     with   the   federal
    government. 
    21 U.S.C. § 822
    (a)(1). This mandate applies to anyone
    seeking to "produc[e]" or "cultivat[e]" marijuana, a schedule I
    substance.      
    Id.
     § 802(15), (22) (defining "manufacture" to include
    production and cultivation); see also id. § 812, sched. I(c)(10)
    (designating "[m]arihuana" as a schedule I controlled substance).1
    Congress granted the Attorney General the authority to
    register prospective manufacturers of controlled substances, see
    id. §§ 822(a), 823(a), and the authority "to promulgate rules and
    1  We use the terms marijuana (or marihuana as the CSA calls
    it) and cannabis interchangeably throughout this opinion.
    - 3 -
    regulations . . . relating to the registration and control of the
    manufacture,      distribution,        and      dispensing       of     controlled
    substances," id. § 821.          The Attorney General in turn delegated
    those powers to the Administrator of the DEA.                     See 
    28 C.F.R. § 0.100
    .
    Pursuant to this delegated authority, the DEA "shall
    register an applicant to manufacture controlled substances in
    schedule I or II if [the agency] determines that such registration
    is consistent with the public interest and with United States
    obligations    under     international          treaties,     conventions,      or
    protocols in effect on May 1, 1971."                  
    21 U.S.C. § 823
    (a).       To
    determine   whether    registration        is   consistent    with    the   public
    interest,   the   statute        enumerates     six    factors   that    must   be
    considered,    including    the     "maintenance       of   effective    controls
    against diversion" of the substance, "compliance with applicable
    State and local law," the "prior conviction record of [the]
    applicant," and "such other factors as may be relevant to and
    consistent with the public health and safety."                
    Id.
         The statute
    does not specify how the DEA is to determine that a registration
    is   consistent   with     the    United     States'     international      treaty
    obligations.
    The pertinent treaty obligations to which the parties
    direct us are those set forth in the Single Convention on Narcotic
    Drugs, Mar. 30, 1961, 18 U.S.T. 1407, 520 U.N.T.S. 204 (the "Single
    - 4 -
    Convention").    As relevant here, the Single Convention requires
    signatories to "prohibit the production, manufacture, export and
    import of, trade in, possession or use of [substances including
    cannabis] except for amounts which may be necessary for medical
    and scientific research only."       
    Id.
     art. 2.5(b).     With respect to
    cannabis specifically, the treaty adopts the "system of controls
    as provided in article 23 [of the Single Convention] respecting
    the control of the opium poppy."         
    Id.
     art. 28.1.   Those controls
    require that a signatory's designated government agency (here, the
    DEA): (1) "designate the areas in which . . . cultivation . . .
    shall be permitted"; (2) authorize only "licensed" cultivators to
    "engage in such cultivation"; (3) "specify the extent of the land
    on which the cultivation is permitted"; (4) "purchase and take
    physical possession of" the cultivated crops; and (5) "have the
    exclusive right of importing, exporting, wholesale trading and
    maintaining stocks other than those held by manufacturers of . . .
    medicinal [cannabis] or [cannabis] preparations."          
    Id.
     art. 23.2.
    Article 23 also makes clear that the functions described above
    must   be   "discharged   by   a   single   government    agency   if   the
    constitution of the [signatory nation] permits it." 
    Id.
     art. 23.3.
    B.
    Prior to the initiation of the present petitions for
    review, the DEA had licensed only a single grower under the
    registration scheme detailed above -- the National Center for
    - 5 -
    Natural Products Research (the "National Center"), a division of
    the University of Mississippi.                See Lyle E. Craker; Denial of
    Application, 
    74 Fed. Reg. 2101
    , 2104 (Jan. 14, 2009). The National
    Center grows cannabis under a contract with the National Institute
    on Drug Abuse, a component of the Department of Health and Human
    Services.    See 
    id.
    In 2016, due in part to greater public interest in
    research    involving      cannabis,     the    DEA   announced    a    new   policy
    designed to increase the number of federally registered cannabis
    growers.      See    Applications        To    Become   Registered      Under    the
    Controlled   Substances       Act   To   Manufacture     Marijuana       To   Supply
    Researchers in the United States, 
    81 Fed. Reg. 53,846
    , 53,847
    (Aug. 12, 2016).         Under the 2016 program, licensed growers would
    be   "permitted     to    operate   independently,       provided      the    grower
    agrees . . . that it will only distribute marijuana with prior,
    written approval from DEA."         
    Id. at 53,848
    .      A number of interested
    parties, including the petitioners, submitted applications to grow
    cannabis under this new policy.
    Over    the    next   few    years,   however,   the       DEA    neither
    approved nor denied any applications pursuant to the 2016 program.
    Unbeknownst to the applicants, the Department of Justice's Office
    of Legal Counsel (OLC)            -- the entity charged with providing
    authoritative legal advice to executive branch agencies -- was
    asked to evaluate the lawfulness of the DEA's existing marijuana
    - 6 -
    licensing practices, including the 2016 program.             In June 2018,
    the OLC issued a formal legal opinion to the acting chief counsel
    of the DEA, concluding that the agency "must change its current
    practices   and    the   [2016   program]   to   comply   with   the   Single
    Convention."      Licensing Marijuana Cultivation in Compliance with
    the Single Convention on Narcotic Drugs at 2 (Off. Legal Couns.
    Jun. 6, 2018), https://www.justice.gov/olc/file/1272131/download
    (the "Marijuana Cultivation Opinion").             Specifically, the OLC
    explained that to fulfill the United States' obligations under the
    Single Convention, the "DEA must adopt a framework in which it
    purchases and takes possession of the entire marijuana crop of
    each licensee after the crop is harvested," and the agency "must
    generally monopolize the import, export, wholesale trade, and
    stock maintenance of lawfully grown marijuana."            
    Id.
        The OLC's
    Marijuana Cultivation Opinion was not released to the public at
    the time.
    To comply with the OLC's directive, the DEA announced in
    March 2020 a notice of proposed rulemaking, indicating its intent
    to adopt new rules that would supersede the 2016 program and
    "ensure that DEA regulations comply with applicable law." Controls
    To Enhance the Cultivation of Marihuana for Research in the United
    States, 
    85 Fed. Reg. 16,292
    , 16,294 (proposed Mar. 23, 2020) (to
    be codified at 21 C.F.R. pts. 1301, 1318) (the "Proposed Rule").
    In apparent reference to the OLC's Marijuana Cultivation Opinion,
    - 7 -
    the notice of proposed rulemaking indicated that the "DOJ advised
    DEA that it must adjust its policies and practices to ensure
    compliance with the CSA, including the CSA's requirement that
    registrations be consistent with the Single Convention," but the
    notice did not include or otherwise incorporate the OLC opinion.
    
    Id.
       The notice identified the relevant provisions of the Single
    Convention, see 
    id. at 16
    ,293–94, and indicated that the Proposed
    Rule was needed to "ensure that DEA carries out all five functions
    under Article 23 and Article 28 of the Single Convention pertaining
    to marihuana," 
    id. at 16,298
    .     The notice of proposed rulemaking
    invited comments from the public and interested parties through
    May 22, 2020.   See 
    id. at 16,292
    .
    Seeking to review the advice from the DOJ that was
    referenced in the notice of proposed rulemaking, SRI sued the DEA
    and the DOJ under the Freedom of Information Act's affirmative
    disclosure provision.     See 
    5 U.S.C. § 552
    (a)(2).     That case
    eventually settled, with the DOJ publishing the OLC's Marijuana
    Cultivation Opinion to its electronic reading room on April 29,
    2020, twenty-three days before the end of the comment period for
    the Proposed Rule.
    Ultimately, after considering public comments, the DEA
    issued a final rule, adopting the Proposed Rule with one minor
    modification not relevant to the present petitions.     See Controls
    to Enhance the Cultivation of Marihuana for Research in the United
    - 8 -
    States, 
    85 Fed. Reg. 82,333
     (Dec. 18, 2020) (codified at 21 C.F.R.
    pts. 1301, 1318) (the "Final Rule").                      The Final Rule addressed,
    among   other       things,    public    comments         the   agency   had       received
    regarding the DEA's obligations to control cannabis under federal
    law and the Single Convention.                 See 
    id. at 82
    ,338–40.               It also
    responded      to    comments        pertaining      to     the    agency's        proposed
    definition of the term "medicinal cannabis," see 
    id. at 82,340
    ,
    which the Final Rule defined to mean "a drug product made from the
    cannabis    plant,      or    derivatives      thereof,         that   can    be    legally
    marketed under the Federal Food, Drug, and Cosmetic Act [(FDCA)],"
    see 
    21 C.F.R. § 1318.02
    (b); see also Final Rule, 85 Fed. Reg. at
    82,344.
    The Final Rule does not preclude the DEA from registering
    more cultivators of cannabis.               Indeed, the DEA explained that one
    of the purposes of the rule was "to increase the number and variety
    of marihuana growers in order to diversify the supply available to
    researchers."        Final Rule, 85 Fed. Reg. at 82,337.                 The agency in
    fact approved SRI's application to manufacture cannabis last fall.
    The petitioners nonetheless challenge the rule as procedurally
    deficient,      in    excess    of    the    DEA's    rulemaking       authority,       and
    arbitrary and capricious, while Craker (arguing only for himself)
    also claims the rule is impermissibly retroactive as applied to
    his   still     pending       application.           We    address     each    of     these
    contentions in detail below.
    - 9 -
    II.
    Under the Administrative Procedures Act (APA), we set
    aside agency action that is "arbitrary, capricious, an abuse of
    discretion, or otherwise not in accordance with law."                
    5 U.S.C. § 706
    (2)(A).    When an agency seeks to promulgate a legislative
    rule (like the Final Rule), the APA generally requires the agency
    to first publish a notice of proposed rulemaking and provide
    interested parties with a meaningful opportunity to comment on the
    proposal. See 
    id.
     § 553.       An agency's failure to comply with these
    procedural requirements renders a rule invalid.              See N.H. Hosp.
    Ass'n v. Azar, 
    887 F.3d 62
    , 70 (1st Cir. 2018).
    III.
    The       petitioners    begin    by   raising     two     perceived
    procedural defects with the DEA's notice of proposed rulemaking
    that would demand the Final Rule be set aside.             First, they argue
    that the DEA failed to provide the public with a meaningful
    opportunity    to    engage   in   the   notice-and-comment        process   by
    declining to disclose the legal basis for the Proposed Rule --
    namely, the full reasoning in the then-undisclosed OLC opinion
    advising the DEA that it must change its registration policies to
    comply with federal law and the Single Convention.                 Second, the
    petitioners assert that the DEA never offered its own reasoned
    explanation for the rule and instead erroneously characterized
    - 10 -
    itself as bound to follow the directives of the OLC's Marijuana
    Cultivation Opinion.     We address each contention in turn.
    A.
    We first consider whether the DEA complied with its
    procedural obligations under the APA to adequately explain the
    legal basis of its rulemaking in its March notice.               Unless an
    exception    applies,   the    APA    requires    federal   agencies,     when
    promulgating new legislative rules, to first publish a notice of
    proposed rulemaking in the Federal Register.             
    5 U.S.C. § 553
    (b).
    This notice must include "reference to the legal authority under
    which the rule is proposed."         
    Id.
     § 553(b)(2).
    The petitioners argue that the DEA's notice of proposed
    rulemaking violated the APA's procedural requirements by failing
    to disclose the agency's legal basis for its new rule.            They take
    aim at the DEA's reference to the OLC's then-unpublished Marijuana
    Cultivation Opinion advising the DEA that it must adjust its
    registration practices to ensure compliance with federal law and
    the Single Convention.        This reference, without actual disclosure
    of the full OLC opinion, the petitioners argue, deprived the public
    of a meaningful opportunity to participate in the rulemaking
    process.
    The   petitioners'       reliance    on   section 553(b)(2)    is
    misplaced.    We have explained that section 553(b)(2) primarily
    "functions to ensure that the agency considers whether it actually
    - 11 -
    has the authority to make the rule it is proposing, and to give
    interested parties a chance to comment on that question."        United
    States v. Whitlow, 
    714 F.3d 41
    , 46 (1st Cir. 2013).        That is, it
    is designed to make clear to the public the "ostensible basis and
    scope of the agency's authority."        Id.; see also Telesat Can. v.
    FCC, 
    999 F.3d 707
    , 713 (D.C. Cir. 2021) (explaining that the agency
    met its obligation under section 553(b)(2) by "referencing the
    relevant legal authority" and "clearly identif[ying] the basic
    governing statute").
    The DEA's notice of proposed rulemaking did just that.
    It indicated that the Proposed Rule was
    being    issued   pursuant   to   the    [DEA]
    Administrator's authority under the CSA "to
    promulgate rules and regulations and to charge
    reasonable fees relating to the registration
    and control of the manufacture, distribution,
    and dispensing of controlled substances," and
    to   "promulgate   and  enforce   any   rules,
    regulations, and procedures which he may deem
    necessary and appropriate for the efficient
    execution of his functions under [the CSA]."
    85 Fed. Reg. at 16,293 (citations omitted and second alteration in
    original) (first quoting 
    21 U.S.C. § 821
     and then quoting 
    21 U.S.C. § 871
    (b)).   The notice cited to the relevant provisions of the CSA
    and   described    both   the    registration      requirement   under
    section 822(a)(1) and the conditions of registration explicated in
    section 823(a).    See Proposed Rule, 85 Fed. Reg. at 16,293.
    Indeed, the petitioners concede in reply that they "have never
    - 12 -
    disputed DEA's legal authority to promulgate the rules at issue
    here."      Accordingly, the public was properly on notice of the
    provenance of the DEA's rulemaking authority.
    Relying primarily on D.C. Circuit law, the petitioners
    nonetheless contend that section 553(b)(2) requires agencies to
    make available to the public the "data the agency used to develop
    the proposed rule."          Am. Med. Ass'n v. Reno, 
    57 F.3d 1129
    , 1133
    (D.C. Cir. 1995) (quoting Engine Mfrs. Ass'n v. EPA, 
    20 F.3d 1177
    ,
    1181 (D.C. Cir. 1994)).           But it is unclear how this bears on the
    present question.         A requirement to disclose relevant data sounds
    more   in   section 553(b)(3)'s          directive     that   a   notice    include
    "either     the   terms      or   substance     of   the   proposed    rule   or    a
    description       of   the    subjects    and    issues    involved,"      than    in
    section 553(b)(2)'s requirement to include "reference to the legal
    authority under which the rule is proposed."                  Cf. Conn. Light &
    Power Co. v. Nuclear Reg. Comm'n, 
    673 F.2d 525
    , 530–31 (D.C. Cir.
    1982) (explaining that section 553(b)(3) requires agencies to
    disclose "the technical basis for a proposed rule").
    In any event, the DEA's notice of proposed rulemaking
    did disclose the legal reasoning behind the Proposed Rule, albeit
    not at the same fulsome level of detail as in the OLC's Marijuana
    Cultivation       Opinion.        For   instance,    the   notice     of   proposed
    rulemaking describes the five requirements in article 23(2) of the
    Single Convention for the supervision, licensing, and distribution
    - 13 -
    of marijuana.       See Proposed Rule, 85 Fed. Reg. at 16,294.              And it
    explains that while the DEA "already directly performs [three of
    the listed] functions," "[i]n order to ensure that DEA complies
    with    the   CSA    and    grants     registrations     that   are     consistent
    with . . . articles 23 and 28 of the Single Convention," the
    "proposed rule would amend DEA's regulations so that DEA directly
    carries out [the] remaining two functions."              Id.    This fairly gave
    notice to the public, including the petitioners, that issuing the
    Proposed Rule was motivated by the conclusion that the DEA's
    current marijuana registration scheme did not fully comply with
    the relevant articles of the Single Convention as required by the
    CSA.
    Even if we were to agree with the petitioners that the
    APA    requires     the    DEA   to   have   disclosed   the    OLC's    Marijuana
    Cultivation Opinion in its notice of proposed rulemaking, the
    petitioners can point to no prejudice resulting from this supposed
    failure to include more detail about the legal basis of the
    Proposed Rule.       See 
    5 U.S.C. § 706
     ("[D]ue account shall be taken
    of the rule of prejudicial error."); see also Am. Radio Relay
    League, Inc. v. FCC, 
    524 F.3d 227
    , 237 (D.C. Cir. 2008) (noting
    that the failure to disclose information for public comment is
    subject to the rule of prejudicial error).               The OLC's opinion was
    publicly      disclosed     during     the   comment     period,   and    various
    commenters -- including SRI and an entity affiliated with Craker
    - 14 -
    -- had an opportunity to raise issues relating to the document.
    See, e.g., Final Rule, 85 Fed. Reg. at 82,340–41 (responding to
    "some commenters['s] suggest[ion] that DEA and DOJ misinterpreted
    the Single Convention").      The petitioners do not explain what
    additional, concrete commentary they would have introduced had the
    OLC's opinion been disclosed sooner.
    B.
    The petitioners also argue that the DEA's rule must be
    set aside because the agency failed to provide its own reasoned
    explanation for the rule by impermissibly substituting the OLC's
    interpretation for its own.   The petitioners, however, point to no
    authority supporting their view that an agency cannot justify an
    action based on its adoption of the OLC's controlling legal advice.
    The OLC's purpose, after all, is to provide such authoritative
    guidance to executive branch agencies.   And bound or not, there is
    no indication that the DEA did not itself agree with the OLC's
    view on the interpretation of the CSA in the Final Rule.       See,
    e.g., Final Rule, 85 Fed. Reg. at 82,340 (noting that the "DEA is
    bound by the law as DOJ and DEA understand it" (emphasis added)).
    Accordingly, there is no merit to the petitioners' argument that
    this dooms the DEA's rule.
    IV.
    The petitioners next contend that the Final Rule exceeds
    the DEA's rulemaking authority.    First, they argue that the Final
    - 15 -
    Rule   contravenes   the   CSA     by   imposing    requirements     that   are
    different from the six enumerated "public interest" factors.                See
    
    21 U.S.C. § 823
    (a).        Second, they assert that the Final Rule
    impermissibly   limits     the    DEA's      statutory   authority   to   waive
    section 823(a)'s registration requirements.               See 
    id.
     § 822(d).
    And, third, they argue that the DEA's definition of "medicinal
    cannabis" in the Final Rule is unduly narrow because it requires
    cannabis products be legally marketable under the FDCA to qualify.
    The petitioners instead contend that the term "medicinal" must be
    given a broader meaning.         We consider each argument in turn.
    A.
    The petitioners argue that the Final Rule exceeds the
    DEA's rulemaking authority because it is contrary to Congress's
    express instruction to register applicants to manufacture cannabis
    if doing so is "consistent with the public interest."                
    21 U.S.C. § 823
    (a).    Section 823(a) lists six factors that the DEA must
    consider when determining the public interest:
    (1) maintenance of effective controls against
    diversion     of     particular     controlled
    substances . . . by limiting the importation
    and bulk manufacture of such controlled
    substances to a number of establishments which
    can produce an adequate and uninterrupted
    supply of these substances under adequately
    competitive    conditions    for    legitimate
    medical, scientific, research, and industrial
    purposes;
    (2) compliance with applicable State and local
    law;
    - 16 -
    (3) promotion of technical advances in the art
    of manufacturing these substances and the
    development of new substances;
    (4) prior conviction record of applicant under
    Federal and State laws relating to the
    manufacture, distribution, or dispensing of
    such substances;
    (5) past experience in the manufacture of
    controlled substances, and the existence in
    the establishment of effective control against
    diversion; and
    (6) such other factors as may be relevant to
    and consistent with the public health and
    safety.
    
    Id.
       § 823(a).2      The   Final   Rule   references   these     six   factors
    verbatim.     It     also   identifies     considerations   of    "particular
    emphasis" for determining the public interest.               See 
    21 C.F.R. § 1318.05
    (b); see also Final Rule, 
    85 Fed. Reg. 82,353
    –54.                These
    considerations include "[w]hether the applicant has demonstrated
    prior compliance with [the CSA] and this chapter [of the DEA's
    regulations]."       
    21 C.F.R. § 1318.05
    (b)(1).
    The petitioners assert that the Final Rule nevertheless
    contravenes section 823(a) for two main reasons.
    1.
    First,    the   petitioners    contend   that   the   Final    Rule
    impermissibly allows the DEA to consider factors not expressly
    2 The petitioners make no argument that section 823(a) is
    itself beyond Congress's legislative authority.
    - 17 -
    enumerated   in   section 823(a)   --   namely,   an   applicant's   past
    compliance with state and local laws (as opposed to its current
    compliance) and an applicant's compliance with federal law (as
    opposed to, more narrowly, its "prior conviction record").            In
    support of this narrow reading, the petitioners point out that
    section 823(a)(2) only lists "compliance with applicable State and
    local law" as a factor to be considered, without any express
    mention of past compliance.    And they contrast the more specific
    reference to an applicant's "prior conviction record under Federal
    and State laws" in section 823(a)(4) with more general references
    to "compliance . . . with applicable Federal, State, and local
    law" elsewhere in the section, see 
    21 U.S.C. § 823
    (h)(2); see also
    
    id.
     § 823(f)(4).    These language choices, the petitioners argue,
    demonstrate that Congress did not intend for the DEA to consider
    these other factors.
    But the petitioners' reading of the CSA finds limited
    support in the text of the statute.       The CSA expressly vests the
    DEA with the authority to register an applicant to cultivate
    cannabis "if [the agency] determines that such registration is
    consistent with the public interest," listing six factors the
    agency must consider. 
    21 U.S.C. § 823
    (a). While Congress required
    the DEA to assess specific factors such as "compliance with
    applicable State and local law" and the "prior conviction record
    of [an] applicant under Federal and State laws," 
    id.
     § 823(a)(2),
    - 18 -
    (4), the statute also directs the DEA to consider "such other
    factors as may be relevant to and consistent with the public health
    and safety,"         id.   § 823(a)(6).       The question     then is whether
    considerations like the applicant's past compliance with state and
    local   laws    and    compliance      with   federal   law    are   "such      other
    factors."
    The DEA thought so, and so do we, even without the
    benefit of any deference to the DEA's interpretation that might be
    called for.       The statute expressly authorizes the DEA to consider
    "other factors as may be relevant to and consistent with the public
    health and safety." Id. Congress itself has concluded that "[t]he
    illegal . . . distribution[] and possession and improper use of
    controlled substances have a substantial and detrimental effect on
    the health and general welfare of the American people."                           Id.
    § 801(2).      Given these considerations, the petitioners make no
    serious argument that past compliance with federal, state, or local
    laws is not "relevant to and consistent with the public health and
    safety."    Id.      § 823(a)(6).      And, indeed, the Final Rule explained
    that, among other things, prior compliance is "relevant to past
    experience      in     the   manufacture      of   a    schedule I       controlled
    substance, past experience in preventing diversion of a controlled
    substance      from    other    than     DEA-authorized       sources,    and    the
    promotion and protection of public health and safety," as well as
    "determining whether the applicant can be entrusted with the
    - 19 -
    responsibilities associated with being a DEA registrant."                    85 Fed.
    Reg. at 82,335.          We see nothing in the DEA's explanation that
    conflicts with section 823(a) or would lead us to part company
    with the agency's reading of the statute.
    2.
    The    petitioners      next     complain    that    the    Final      Rule
    misconstrues       section 823(a)(1),         which     directs     the      DEA    to
    "consider[]"       the   "maintenance      of   effective       controls     against
    diversion of [cannabis] by limiting the importation and bulk
    manufacture of [cannabis] to a number of establishments which can
    produce an adequate and uninterrupted supply of these substances
    under adequately competitive conditions for legitimate medical,
    scientific,    research,      and    industrial       purposes."        
    21 U.S.C. § 823
    (a)(1).       They contend that the DEA impermissibly reads the
    provision     to    require   the     agency     to     limit     the   number      of
    manufacturers to only the number of establishments that can produce
    an adequate and uninterrupted supply of cannabis under adequately
    competitive conditions.        See Final Rule, 85 Fed. Reg. at 82,336–
    37. And they argue that the DEA's interpretation of that provision
    to mandate (rather than merely "consider") an upper limit to the
    number of registrants conflicts with both the CSA and the DEA's
    prior interpretation of the relevant provision.
    Contrary to the petitioners' contentions, however, the
    Final Rule does not purport to apply a specific cap on the number
    - 20 -
    registrants.    First, with respect to the CSA, the regulation as
    codified simply restates the statutory language verbatim.        Compare
    
    21 C.F.R. § 1318.05
    (a)(1), with 
    21 U.S.C. § 823
    (a)(1).           To the
    extent   the   petitioners   find   fault   with   the   DEA's   further
    explanation that it is "not allowed to register an unlimited amount
    of manufacturers" and "must perform an analysis of each application
    to determine whether the addition of the applicant is necessary to
    provide the adequate and uninterrupted supply of marihuana for
    research needs or whether the legitimate need will be met by the
    registration of others," Final Rule, 85 Fed. Reg. at 82,336, those
    statements are consistent with both the CSA and the DEA's prior
    rulemakings.
    In particular, the petitioners fasten attention to a
    footnote in a past DEA action that acknowledged that "the CSA . . .
    does not unambiguously impose an absolute ceiling on the number of
    registered manufacturers."    Lyle E. Craker; Denial of Application,
    74 Fed. Reg. at 2128 n.105.    But that same footnote also explained
    that "[n]onetheless," section 823(a)(1) "can be construed to mean
    that DEA . . . must consider keeping as the upper boundary on the
    number of manufacturers that which can produce an adequate and
    uninterrupted supply under adequately competitive conditions."
    Id.   That is, the DEA interpreted the CSA in its earlier action as
    "retain[ing] the concept of an upper limit on the number of
    manufacturers as a factor to be considered when evaluating an
    - 21 -
    application for registration under § 823(a)."                   Id.     The Final
    Rule neatly follows the DEA's prior interpretation as well as the
    text    of   section 823(a)(1)     --    which,       again,    the   Final    Rule
    incorporates verbatim.      We therefore do not read this portion of
    the Final Rule as contrary to either the CSA or the DEA's own
    interpretive precedent.
    B.
    The   petitioners    argue        next    that    the    Final   Rule
    impermissibly circumscribes the DEA's authority under the CSA to
    waive registration requirements in certain circumstances.                       The
    statute permits the DEA to, "by regulation, waive the requirement
    for    registration   of   certain      manufacturers,         distributors,    or
    dispensers if [the agency] finds it consistent with the public
    health and safety." 
    21 U.S.C. § 822
    (d). During the public comment
    period, various commentors urged the DEA to exercise its authority
    under    section 822(d)    to    waive       registration      requirements    for
    growers who supply cannabis to researchers.                   In the Final Rule,
    the DEA explained why it declined to do so.               See 85 Fed. Reg. at
    82,335–36.
    The petitioners' primary argument appears to be that the
    DEA erred by refusing to even consider the possibility that it
    could grant waivers of the registration requirement for cannabis
    growers who supply researchers.              This characterization, however,
    is belied by the fact that the agency did consider the issue in
    - 22 -
    its rulemaking; it simply decided not to exercise its authority in
    the way that the petitioners hoped it would.      See id.   And while
    the petitioners suggest that the DEA's justifications in the Final
    Rule for declining to so waive the registration requirements are
    insufficient, they never explain how section 822(d) in any way
    compels the DEA to exercise its waiver authority in this instance.
    Take, for example, the petitioners' dissatisfaction with
    the   DEA's   explanation    that    "waiving   the   requirement   of
    registration for marihuana growers who supply researchers would be
    inconsistent with U.S. obligations under the Single Convention."
    Id. at 82,336.   To be sure, the petitioners are correct that it is
    only section 823(a) -- the provision laying out the registration
    requirements -- that instructs the DEA to consider compliance with
    the Single Convention.      But that does not mean the DEA was off-
    base in determining that it would nonetheless be unwise to grant
    a waiver of registration that would violate the United States'
    treaty obligations.   The petitioners' rejoinders at best establish
    that the agency was not obliged to decline to so exercise its
    authority; they do not demonstrate that the agency erred in making
    a discretionary decision to not waive registration.
    C.
    The petitioners next argue that the DEA's definition of
    the term "medicinal cannabis" in the Final Rule should be set
    aside.   To recap, the DEA's rule defines "medicinal cannabis" as
    - 23 -
    "a drug product made from the cannabis plant, or derivatives
    thereof, that can be legally marketed under the Federal Food, Drug,
    and Cosmetic Act."      
    21 C.F.R. § 1318.02
    (b); see also Final Rule,
    Fed. Reg. at 82,340.       The petitioners contend that the agency's
    definition is inconsistent with the plain meaning of "medicinal"
    and contrary to both the structure and scheme of the Single
    Convention and federal law.
    To explain why the petitioners miss the mark, we begin
    by tracing how the DEA arrived at its definition of medicinal
    cannabis.    In the Final Rule, the agency observed that "the Single
    Convention does not define medicinal cannabis."              85 Fed. Reg. at
    82,340.   At the same time, the DEA did not reject the petitioners'
    view that the Single Convention's understanding of "medicinal
    cannabis" is informed by its definition of "medicinal opium." See,
    e.g., id. at 82,344 n.17 (noting that the definition for "medicinal
    opium" in the Single Convention "appl[ies] to cannabis through
    Article 28").    Because the Single Convention defines "medicinal
    opium" to mean "opium which has undergone the processes necessary
    to adapt it for medicinal use," Single Convention, art. 1, § 1(o),
    there is support for the petitioners' position that the Single
    Convention    would    embrace   a    broader   definition    of   "medicinal
    cannabis" than what the DEA put forward.
    However,    rather       than   borrowing   verbatim     whatever
    definition of "medicinal cannabis" could be gleaned from the Single
    - 24 -
    Convention,    the     DEA    chose   instead       to   "adapt[]   the   Single
    Convention's definition[] to reflect federal law, including the
    [FDCA] and the CSA."          Final Rule, 85 Fed. Reg. at 82,344 n.17.
    That is, while the agency's definition of medicinal cannabis
    "track[ed]"    the    Single   Convention's     definition,     the    DEA    also
    "adapted" that definition "to account for Federal law."                   Id. at
    82,344. The question then is whether the DEA's decision to "adapt"
    the definition in the Single Convention to include only products
    approved for marketing under the FDCA was a reasonable exercise of
    its rulemaking authority.
    As an initial matter, there is no question that the DEA
    has the authority to establish its own definition of "medicinal
    cannabis" in the context of the federal registration scheme.                  The
    CSA   grants    the     DEA    the    power    to    "promulgate      rules   and
    regulations . . . relating to the registration and control of the
    manufacture, distribution, and dispensing of [cannabis]."                      
    21 U.S.C. § 821
    .         And it specifies that the DEA shall register
    applicants to manufacture cannabis if the agency "determines that
    such registration is consistent with the public interest and with
    United States obligations under international treaties," including
    the Single Convention.         
    Id.
     § 823(a).         Accordingly, it is well
    within the DEA's statutory mandate to define a term that implicates
    its control over stocks of cannabis and that relates to both the
    - 25 -
    public interest and the United States' obligations under the Single
    Convention.
    As for whether the definition the DEA arrived at is
    arbitrary or capricious, the petitioners point us to nothing that
    demonstrates     that   the    agency's       understanding    of   "medicinal
    cannabis"    contravenes      the    CSA,   violates     the   United    States'
    obligations under the Single Convention, or is otherwise contrary
    to law.     Beginning with the CSA, we observe that the statute has
    no definition of "medicinal cannabis" of its own and never even
    uses the term.    The CSA classifies cannabis as a schedule I drug.
    See 
    21 U.S.C. § 812
    , sched. I(c)(10); see also Gonzales v. Raich,
    
    545 U.S. 1
    , 14 (2005).     And it mandates that the DEA in registering
    cultivators    consider    the      "maintenance    of    effective     controls
    against diversion."     
    21 U.S.C. § 823
    (a)(1).           Given this regulatory
    scheme, it is hardly arbitrary or capricious for the DEA to define
    "medicinal cannabis" -- as that term is used by the DEA in its own
    rule -- in a way that keeps stocks of cannabis produced by
    registered growers within the agency's exclusive control, at least
    until any such cannabis intended for medicinal use can be legally
    marketed under federal law.
    As for the Single Convention, all parties agree that the
    DEA's definition of "medicinal cannabis" is no broader than the
    treaty's definition of the term.               For that reason, we see no
    conflict between the DEA's chosen definition and the United States'
    - 26 -
    obligations under the Single Convention.                     The Single Convention
    allows the United States to forego asserting exclusive control
    over "medicinal cannabis" as that term is used in the treaty.                           See
    Single Convention, art. 23, § 2(e) ("Parties need not extend this
    exclusive right to medicinal [cannabis].").                       But nothing in the
    Single Convention requires a signatory to forego that control over
    any stock of cannabis, including medicinal cannabis.                          And for the
    reasons already explained, the DEA's justification for retaining
    its exclusive rights over a broader stock of cannabis than the
    Single Convention arguably requires -- "to ensure compliance with
    the CSA," Final Rule, 85 Fed. Reg. at 82,340                          -- is neither
    arbitrary nor capricious.
    Trying an alternative approach, the petitioners also
    argue that the DEA's definition of "medicinal cannabis" is contrary
    to our prior decision in Grinspoon v. DEA, 
    828 F.2d 881
     (1st. Cir.
    1987).      In    Grinspoon,    we    had        occasion    to   examine      the    CSA's
    statutory        requirements        for     classification          of       schedule I
    substances, specifically the condition that the substance "has no
    currently accepted medical use in treatment in the United States,"
    
    21 U.S.C. § 812
    (b)(1)(B).           The    DEA   promulgated       a    rule   that
    essentially sought to interpret the statutory phrase "accepted
    medical use in treatment in the United States" in the CSA to mean
    "approved      for   interstate       marketing         by   the    [Food      and    Drug
    Administration (FDA)] under the FDCA."                  See Grinspoon, 828 F.2d at
    - 27 -
    884.     We concluded that the DEA's limiting construction was
    contrary to congressional intent because it was "plainly possible
    that a substance may fail to obtain interstate marketing approval
    even if it has an accepted medical use."                 
    Id.
     at 887–88.
    Here, though, the DEA was not engaged with defining a
    statutory term. And the statutory direction was simply to register
    prospective cannabis cultivators based on the public interest and
    the need to comply with the nation's treaty obligations, see 
    21 U.S.C. § 823
    (a),    and    to    promulgate         rules   "relating      to    the
    registration and control of [cannabis]," 
    id.
     § 821.                        And as we
    have discussed, nothing in the definition exceeded the agency's
    statutory authority or put the United States in breach of its
    treaty obligations.
    The petitioners also assert that the DEA's definition of
    "medicinal      cannabis"     conflicts    with        various    FDA     regulations
    indicating      the   FDA's    endorsement        of     research       and   medical
    treatments involving federally regulated substances that have not
    been approved for interstate marketing under the FDCA.                             This
    supposedly      demonstrates       that   the    FDA    understands        that    such
    substances may be "medicinal" even if they have not undergone the
    relevant approval process. But here we are not weighing the wisdom
    of competing interpretations by different federal agencies over
    the    same   statutory     provisions.         Just    because     the    FDA    might
    reasonably construe the statutes it administers to provide for a
    - 28 -
    broader definition of "medicinal cannabis" does not mean that the
    DEA acts arbitrarily or capriciously when it defines "medicinal
    cannabis" more narrowly for its own purposes.         It is no surprise
    -- and no mark of unreasonableness -- that the FDA might have a
    different definition of "medicinal cannabis" in one context than
    the DEA does for its work in other contexts.3
    In sum, the DEA has for its purposes crafted its own
    definition of medicinal cannabis that is based on, but not wholly
    equivalent to, that in the Single Convention.              That definition
    neither breaches any treaty obligation of the United States nor
    violates federal law.      And the DEA did not act arbitrarily or
    capriciously in concluding that it must maintain exclusive control
    over stocks of a schedule I drug produced under federal law until
    medicinal products containing that substance are approved for
    marketing by the FDA.      For these simple reasons, we reject the
    petitioners'   challenge   to   the   DEA's   definition    of   "medicinal
    cannabis."
    3  The above reasoning also explains why the petitioners are
    incorrect to assert that the DEA's definition of "medicinal
    cannabis" in the context of interpreting its authority under the
    CSA impermissibly regulates medical practice.          The DEA's
    definition relates to what subset of cannabis must be exclusively
    controlled by the DEA -- something the CSA and the Single
    Convention requires the agency to consider. It does not concern
    what activities are or are not permissible aspects of medical
    practice.   Accordingly, we do not view the agency's actions as
    exceeding its congressionally delegated authority in this way.

    Finally,    the    petitioners        argue      that   the   DEA's   new
    regulatory framework for registrations, even if it is within the
    agency's rulemaking authority, must be set aside as arbitrary,
    capricious, or otherwise contrary to law.               The petitioners begin
    by   contending    that     the   DEA        failed   to     consider    relevant
    alternatives.     When promulgating new regulations, an agency must
    consider alternatives "within the ambit of the existing [policy],"
    but it need not "consider all policy alternatives in reaching [its]
    decision."   Motor Vehicle Mfrs. Ass'n of U.S., Inc. v. State Farm
    Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 51 (1983); see also DHS v.
    Regents of the Univ. of Cal., 
    140 S. Ct. 1891
    , 1914–15 (2020)
    ("Agencies are not compelled to explore 'every alternative device
    and thought conceivable by the mind of man.'" (quoting Vt. Yankee
    Nuclear Power Corp. v. NRDC, 
    435 U.S. 519
    , 551 (1978)).                   The key
    question is whether the agency "entirely failed to consider an
    important aspect of the problem."             State Farm, 
    463 U.S. at 43
    .
    The petitioners devote all of three sentences in their
    opening brief to this argument.         They do not identify any specific
    aspect of the problem that the DEA missed and make no argument for
    why the DEA's supposed failure to consider the alternatives the
    petitioners point to should doom the entire rule.                   Instead, the
    petitioners vaguely gesture towards two documents -- the OLC's
    Marijuana Cultivation Opinion and SRI's comments to the agency
    - 30 -
    during    the    notice-and-comment         period    --    as   sources    for    the
    purported alternatives the DEA declined to consider.                       And in so
    doing, the petitioners make no attempt to explain why these records
    indicate that the agency "entirely failed to consider an important
    aspect of the problem."        
    Id.
        We therefore treat this argument as
    waived.    United States v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990)
    ("[I]ssues adverted to in a perfunctory manner, unaccompanied by
    some effort at developed argumentation, are deemed waived.").
    The     petitioners      also     argue    that      the    Final     Rule
    arbitrarily       discriminates      between     cannabis        supplied    by    the
    National Center -- the only federally registered cannabis grower
    at the time the rule was promulgated -- and cannabis supplied from
    other sources, including cannabis grown in states that allow it
    under their laws.       During the notice-and-comment period, various
    commentors suggested that federally registered researchers should
    be allowed to obtain cannabis from state-authorized dispensaries.
    See Final Rule, 85 Fed. Reg. at 82,338.                    The DEA rejected this
    proposal,       explaining   that     "[s]tate       licenses      to   manufacture
    marijuana do not satisfy the requirements of Federal law," and,
    therefore, allowing researchers to use state-authorized cannabis
    would violate the CSA.         Id.      The petitioners assert that this
    decision is arbitrary and capricious because it fails to treat
    "like cases alike."          Namely, it permits researchers to obtain
    - 31 -
    cannabis from the National Center but not from state-permitted
    dispensaries.
    But this argument misses a crucial detail:      the National
    Center and state dispensaries are not "like cases."            As the DEA
    explains, the National Center is a federally registered grower
    under the CSA, while state dispensaries are not.       And federal law
    requires that "[e]very person who manufactures or distributes
    [cannabis] . . . shall obtain annually a registration issued by
    the [DEA]."     
    21 U.S.C. § 822
    (a)(1).    It is hardly arbitrary and
    capricious for the DEA to allow federally registered growers to
    supply cannabis while precluding non-federally registered growers
    from doing the same.
    The petitioners point out that, under the OLC's and the
    DEA's reading of the CSA, all of the National Center's historic
    growing activity was also in violation of federal law and the
    Single Convention.      But the petitioners never explain why that
    makes the National Center somehow equivalent to the proposed state
    dispensaries.    Nor do they establish that, after the Final Rule's
    implementation, the National Center's activities would continue to
    be contrary to federal law.
    Lastly, Craker, not joined by fellow petitioner SRI,
    argues that the Final Rule is impermissibly retroactive because it
    applies to pending applications before the DEA.       He explains that
    because   he    (and   30-some-odd   others)   had   already     sent   in
    - 32 -
    applications in response to the DEA's call for applications for
    the 2016 program, it is unfair to pull the rug out from under him
    by applying the new rule to the application he prepared in reliance
    on the prior regime.
    While     we   have    acknowledged       generally     that     "the
    retroactive application of an agency rule is disfavored," we have
    also explained that "the mere filing of an application is not the
    kind of completed transaction in which a party could fairly expect
    stability of the relevant laws as of the transaction date."                    Pine
    Tree Med. Assocs. v. Sec'y of Health and Hum. Servs., 
    127 F.3d 118
    , 121 (1st Cir. 1997).           Particularly where a change involves
    "the substantive standards for granting the application on the
    merits," it does not typically raise the kind of "fair notice and
    retroactivity concerns" that Craker complains of.                   
    Id. at 122
    .
    Previously, we found "no support . . . for the proposition that
    filing   an    application     with       an   agency   essentially    fixes    an
    entitlement to the application of those substantive regulations in
    force on the filing date." 
    Id.
     (emphasis omitted). Craker musters
    up no such support now.             And while Craker points to factual
    differences between his case and Pine Tree, he makes no argument
    as to why those distinctions demand a different legal rule be
    applied.        Thus,    Craker     has    not   identified   any     notice     or
    retroactivity problem that would render the application of the
    - 33 -
    Final Rule to his application arbitrary, capricious, or otherwise
    contrary to law.4
    VI.
    For the foregoing reasons, we deny the petitioners'
    petitions for review.
    4  Craker also argues that the rule suddenly changed the
    status of pending applications from "complete" to "incomplete"
    because of a requirement to submit a new form. But this too does
    not render the rule impermissibly retroactive. Although we have
    noted that "rejecting an application because it fails to meet a
    new regulation governing the proper format or preparation of
    applications that was promulgated after that application was
    filed" could raise notice and retroactivity concerns, Pine Tree,
    
    127 F.3d at 122
    , changing an application's status to "incomplete"
    to account for a new filing requirement is not equivalent to a
    denial, at least without some evidence that the new filing
    requirement essentially effects a rejection.    Here, Craker has
    raised no claim of prejudice from the requirement except that a
    new form must be submitted.
