[[Page 75980]]

SUMMARY: The Administrator of the Drug Enforcement Administration is 
issuing this notice of intent to publish a temporary order to schedule 
two synthetic benzimidazole-opioid substances, N-pyrrolidino 
metonitazene and N-pyrrolidino protonitazene, including their isomers, 
esters, ethers, salts, and salts of isomers, esters, and ethers 
whenever the existence of such isomers, esters, ethers, and salts is 
possible, in schedule I of the Controlled Substances Act. When it is 
issued, the temporary scheduling order will impose the regulatory 
controls and administrative, civil, and criminal sanctions applicable 
to schedule I controlled substances on persons who handle (manufacture, 
distribute, reverse distribute, import, export, engage in research, 
conduct instructional activities or chemical analysis, or possess) or 
propose to handle these two specified substances.

DATES: This notice of intent is effective September 17, 2024.

FOR FURTHER INFORMATION CONTACT: Terrence L. Boos, Drug and Chemical 
Evaluation Section, Diversion Control Division, Drug Enforcement 
Administration; Mailing Address: 8701 Morrissette Drive, Springfield, 
Virginia 22152; Telephone: (571) 362-3249.

SUPPLEMENTARY INFORMATION: The notice of intent contained in this 
document is issued pursuant to the temporary scheduling provisions of 
21 U.S.C. 811(h). The Drug Enforcement Administration (DEA) intends to 
issue a temporary scheduling order \1\ (in the form of a temporary 
amendment) to add the two synthetic benzimidazole-opioid substances, 
including their isomers, esters, ethers, salts, and salts of isomers, 
esters, and ethers whenever the existence of such isomers, esters, 
ethers, and salts is possible, to schedule I under the Controlled 
Substances Act (CSA):
---------------------------------------------------------------------------

    \1\ Though DEA has used the term ``final order'' with respect to 
temporary scheduling orders in the past, this notice of intent 
adheres to the statutory language of 21 U.S.C. 811(h), which refers 
to a ``temporary scheduling order.'' No substantive change is 
intended.
---------------------------------------------------------------------------

    <bullet> 2-(4-methoxybenzyl)-5-nitro-1-(2-(pyrrolidin-1-yl)ethyl)-
1H-benzimidazole (commonly known as, N-pyrrolidino metonitazene or 
metonitazepyne), and
    <bullet> 5-nitro-2-(4-propoxybenzyl)-1-(2-(pyrrolidin-1-yl)ethyl)-
1H-benzimidazole (commonly known as, N-pyrrolidino protonitazene or 
protonitazepyne).
    The temporary scheduling order will be published in the Federal 
Register on or after October 17, 2024.

Legal Authority

    Under 21 U.S.C. 811(h)(1), the CSA provides the Attorney General 
(as delegated to the Administrator of DEA (Administrator) pursuant to 
28 CFR 0.100) has the authority to temporarily place a substance in 
schedule I of the CSA for two years without regard to the evaluation 
requirements of 21 U.S.C. 811(b), if he finds that such action is 
necessary to avoid an imminent hazard to the public safety.\2\ In 
addition, if proceedings to control a substance are initiated under 21 
U.S.C. 811(a)(1) while the substance is temporarily controlled under 
section 811(h), the Attorney General may extend the temporary 
scheduling for up to one year.\3\

    Where the necessary findings are made, a substance may be 
temporarily scheduled if it is not listed in any other schedule under 
21 U.S.C. 812, or if there is no exemption or approval in effect for 
the substance under section 505 of the Federal Food, Drug, and Cosmetic 
Act, 21 U.S.C. 355.\4\

Background

    The CSA requires the Administrator to notify the Secretary of the 
Department of Health and Human Services (HHS) of an intent to 
temporarily place a substance in schedule I of the CSA (i.e., to issue 
a temporary scheduling order).\5\ By letter dated December 15, 2023, 
the Administrator transmitted the required notice to place N-
pyrrolidino metonitazene and N-pyrrolidino protonitazene in schedule I 
on a temporary basis to the Assistant Secretary for Health of HHS 
(Assistant Secretary).\6\ On December 22, 2023, the Assistant Secretary 
responded to this notice and advised DEA that based on a review by the 
Food and Drug Administration (FDA), there are currently no 
investigational new drug applications (IND) or approved new drug 
applications (NDA) for N-pyrrolidino metonitazene or N-pyrrolidino 
protonitazene. The Assistant Secretary also stated that HHS had no 
objection to the temporary placement of these substances in schedule I 
of the CSA. N-Pyrrolidino metonitazene and N-pyrrolidino protonitazene 
currently are not listed in any schedule under the CSA, and no 
exemptions or approvals under 21 U.S.C. 355 are in effect for these 
substances.
---------------------------------------------------------------------------

    \5\ 21 U.S.C. 811(h)(4).
    \6\ The Secretary of HHS has delegated to the Assistant 
Secretary for Health of HHS the authority to make domestic drug 
scheduling recommendations. 58 FR 35460 (July 1, 1993).
---------------------------------------------------------------------------

    To find that temporarily placing a substance in schedule I of the 
CSA is necessary to avoid an imminent hazard to the public safety, the 
Administrator must consider three of the eight factors set forth in 21 
U.S.C. 811(c): the substance's history and current pattern of abuse; 
the scope, duration, and significance of abuse; and what, if any, risk 
there is to the public health.\7\ This consideration includes any 
information indicating actual abuse, diversion from legitimate 
channels, and clandestine importation, manufacture, or distribution of 
N-Pyrrolidino metonitazene and N-pyrrolidino protonitazene.\8\

    Substances meeting the statutory requirements for temporary 
scheduling may only be placed in schedule I.\9\ Substances in schedule 
I have high potential for abuse, no currently accepted medical use in 
treatment in the United States,\10\ and a lack of accepted

safety for use under medical supervision.\11\
---------------------------------------------------------------------------

    \9\ 21 U.S.C. 811(h)(1).
    \10\ When finding schedule I placement on a temporary basis is 
necessary to avoid imminent hazard to the public, 21 U.S.C. 811(h) 
does not require DEA to consider whether the substance has a 
currently accepted medical use in treatment in the United States. 
Nonetheless, there is no evidence suggesting that N-pyrrolidino 
metonitazene or N-pyrrolidino protonitazene have a currently 
accepted medical use in treatment in the United States. To determine 
whether a drug or other substance has a currently accepted medical 
use, DEA has traditionally applied a five-part test to a drug or 
substance that has not been approved by the FDA: i. The drug's 
chemistry must be known and reproducible; ii. there must be adequate 
safety studies; iii. there must be adequate and well-controlled 
studies proving efficacy; iv. the drug must be accepted by qualified 
experts; and v. the scientific evidence must be widely available. 
See Marijuana Scheduling Petition; Denial of Petition; Remand, 57 FR 
10499 (Mar. 26, 1992), pet. for rev. denied, Alliance for Cannabis 
Therapeutics v. Drug Enforcement Admin., 15 F.3d 1131, 1135 (D.C. 
Cir. 1994). DEA and HHS applied the traditional five-part test for 
currently accepted medical use in this matter. In a recent published 
letter in a different context, HHS applied an additional two-part 
test to determine currently accepted medical use for substances that 
do not satisfy the five-part test: (1) whether there exists 
widespread, current experience with medical use of the substance by 
licensed health care providers operating in accordance with 
implemented jurisdiction-authorized programs, where medical use is 
recognized by entities that regulate the practice of medicine, and, 
if so, (2) whether there exists some credible scientific support for 
at least one of the medical conditions for which part (1) is 
satisfied. On April 11, 2024, the Department of Justice's Office of 
Legal Counsel (OLC) issued an opinion, which, among other things, 
concluded that HHS's two-part test would be sufficient to establish 
that a drug has a currently accepted medical use. Office of Legal 
Counsel, Memorandum for Merrick B. Garland Attorney General Re: 
Questions Related to the Potential Rescheduling of Marijuana at 3 
(April 11, 2024). For purposes of this notice of intent, there is no 
evidence that health care providers have widespread experience with 
medical use of N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene or that the use of N-pyrrolidino metonitazene or N-
pyrrolidino protonitazene is recognized by entities that regulate 
the practice of medicine under either the traditional five-part test 
or the two-part test.

Two Benzimidazole-Opioids: N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene

    The continued encounter of novel synthetic opioids on the 
recreational drug market poses a threat to public safety. Beginning in 
2019, a new class of synthetic opioids known as benzimidazole-opioids, 
commonly referred to as ``nitazenes,'' emerged on the recreational drug 
market. This class of substances has a similar pharmacological profile 
to fentanyl, morphine, and other mu-opioid receptor agonists. Between 
August 2020 and March 2024, DEA temporarily controlled ten 
benzimidazole-opioids because they posed a threat to public safety.\12\ 
N-Pyrrolidino metonitazene and N-pyrrolidino protonitazene are some of 
the recently encountered ``nitazene'' synthetic opioids identified on 
the illicit drug market.

Butonitazene, Etodesnitazene, Flunitazene, Metodesnitazene, 
Metonitazene, N-Pyrrolidino etonitazene, and Protonitazene in 
Schedule I, 87 FR 21556 (Apr. 12, 2022); Schedules of Controlled 
Substances: Temporary Placement of Isotonitazene in Schedule I, 85 
FR 51342 (Aug. 20, 2020); Schedules of Controlled Substances: 
Temporary Placement of N-Desethyl Isotonitazene and N-Piperidinyl 
Etonitazene in Schedule I, 89 FR 60817 (Jul. 29, 2024).
---------------------------------------------------------------------------

    The continued trafficking and identification of benzimidazole-
opioids in toxicology cases poses a significant threat to public health 
and safety. Adverse health effects associated with the misuse and abuse 
of synthetic opioids have led to devastating consequences including 
death. Preclinical pharmacology data demonstrate that N-pyrrolidino 
metonitazene and N-pyrrolidino protonitazene have pharmacological 
profiles similar to those of the potent benzimidazole-opioids 
metonitazene and protonitazene, schedule I opioid substances. N-
Pyrrolidino metonitazene and N-pyrrolidino protonitazene have been 
positively identified in at least 26 toxicology cases. As the United 
States continues to experience a high number of opioid-involved 
overdoses and mortalities, the introduction of new designer opioids 
further exacerbates the current opioid epidemic.
    Available data and information for N-pyrrolidino metonitazene and 
N-pyrrolidino protonitazene, summarized below, indicate that these 
substances have high potentials for abuse, no currently accepted 
medical uses in treatment in the United States, and a lack of accepted 
safety for use under medical supervision. DEA's three-factor analysis 
is available in its entirety under ``Supporting and Related Material'' 
of the public docket for this action at www.regulations.gov under 
Docket Number DEA-1337.

Factor 4. History and Current Pattern of Abuse

    Since 2019, there has been an emergence of benzimidazole-opioid 
compounds on the illicit drug market, which have been positively 
identified in numerous cases of fatal overdose events. The 
benzimidazole-opioids were originally synthesized and studied in the 
1950s by the pharmaceutical research laboratories of the Swiss chemical 
company Chemical Industries Basel. The research produced a group of 
structurally unique benzimidazole derivatives with analgesic 
properties; however, the research effort did not produce any medically 
approved analgesic products. These benzimidazole derivatives include 
schedule I substances, such as synthetic opioids clonitazene, 
etonitazene, and isotonitazene.
    In August 2020, isotonitazene was placed in schedule I of the CSA 
(85 FR 51342). Subsequently, nine additional benzimidazole-opioids \13\ 
have been placed in schedule I of the CSA (87 FR 21556 and 89 FR 
60817). Recently, N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene have emerged on the illicit drug market. Law enforcement 
officers have encountered N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene in several solid forms (e.g., powder and tablets). These 
substances are not approved pharmaceutical products and are not 
approved for medical use anywhere in the world. The Assistant Secretary 
in a letter to DEA dated December 22, 2023, stated that there are no 
FDA-approved NDAs or IND applications for N-pyrrolidino metonitazene 
and N-pyrrolidino protonitazene in the United States; hence, there are 
no legitimate channels for these substances as marketed drug products.
---------------------------------------------------------------------------

    \13\ Butonitazene, etodesnitazene, flunitazene, metodesnitazene, 
metonitazene, N-pyrrolidino etonitazene, and protonitazene (87 FR 
21556, Apr. 12, 2022). N-desethyl isotonitazene and N-piperidinyl 
etonitazene (89 FR 60817, Jul. 29 2024).
---------------------------------------------------------------------------

    The appearance of benzimidazole-opioids on the illicit drug market 
is similar to other designer opioid drugs that are trafficked for their 
psychoactive effects. These substances are likely to be abused in the 
same manner as schedule I opioids, such as etonitazene, isotonitazene, 
and heroin. In 2023, N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene emerged on the illicit synthetic drug market as evidenced 
by their identification in forensic drug seizures and in biological 
samples.\14\ Based on NFLIS-Drug data, law enforcement encounters of N-
pyrrolidino metonitazene and N-pyrrolidino protonitazene were found in 
combination with other substances of abuse such as heroin, designer 
benzodiazepines, cocaine, fentanyl, methamphetamine, and xylazine.
---------------------------------------------------------------------------

    \14\ NMS Labs, in collaboration with the Center for Forensic 
Science Research and Education at the Fredric Rieders Family 
Foundation and the Organized Crime Drug Enforcement Task Force at 
the United States Department of Justice, has received funding from 
the Centers for Disease Control and Prevention to develop systems 
for the early identification and notification of novel psychoactive 
substances in the drug supply within the United States.
---------------------------------------------------------------------------

Factor 5. Scope, Duration and Significance of Abuse

    N-Pyrrolidino metonitazene and N-pyrrolidino protonitazene, similar 
to etonitazene, metonitazene and protonitazene (schedule I substances), 
have been described as potent synthetic opioids, and evidence suggests 
they are abused for their opioidergic effects (see Factor 6). The abuse 
of these benzimidazole-opioids, similar to other synthetic opioids, has 
resulted in serious adverse health effects. According to a public alert 
report \15\ published in August 2023, N-pyrrolidino protonitazene has 
been positively confirmed in 20 medicolegal death investigation cases 
in the United States (n =16) and United Kingdom (n = 4). The cases that 
occurred in the United States originated from seven States including 
California, Illinois, Maine, Massachusetts, Minnesota, Wisconsin, and 
Wyoming. N-Pyrrolidino metonitazene has been identified in six 
toxicology cases as of June 2023 in the United States. The cases 
occurred in at least three States including Ohio, Illinois, and West 
Virginia.\16\

    Data from law enforcement suggest that N-pyrrolidino metonitazene 
and N-

[[Page 75982]]

pyrrolidino protonitazene are being abused in the United States as 
recreational drugs.\17\ Since 2023, there have been 37 exhibits 
reported to the NFLIS-Drug (Federal, State and local laboratories) 
database pertaining to the trafficking, distribution, and abuse of 
these substances. There were seven encounters of N-pyrrolidino 
metonitazene from two States in NFLIS-Drug: Missouri (n = 2) and Ohio 
(n = 5). N-Pyrrolidino protonitazene has been identified in 30 exhibits 
in NFLIS-Drug from five States: Florida (n = 4), Iowa (n = 10), 
Missouri (n = 1), Ohio (n = 13), and Texas (n = 2).\18\
---------------------------------------------------------------------------

    \17\ While law enforcement data are not direct evidence of 
abuse, they can lead to an inference that a drug has been diverted 
and abused. See 76 FR 77330, 77332 (Dec. 12, 2011).
    \18\ NFLIS-Drug was queried on July 17, 2024.
---------------------------------------------------------------------------

    Because abusers of N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene are likely to obtain these substances through unregulated 
sources, the identity, purity, and quantity of these substances are 
uncertain and inconsistent, thus posing significant adverse health 
risks to the end user. The misuse and abuse of opioids have been 
demonstrated and are well-characterized.\19\ Individuals who initiate 
(i.e., use a drug for the first time) use of these benzimidazole-
opioids are likely to be at risk of developing substance use disorder, 
an overdose event, or death, similar to that of other opioid analgesics 
(e.g., fentanyl, morphine, etc.). Law enforcement and toxicology 
reports demonstrate that N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene are being illicitly distributed and abused.

---------------------------------------------------------------------------

Factor 6. What, if Any, Risk There Is to the Public Health

    The increase in opioid overdose deaths in the United States has 
been exacerbated recently by the availability of potent synthetic 
opioids on the illicit drug market. Data obtained from pre-clinical 
studies demonstrate that N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene exhibit pharmacological profiles similar to that of 
etonitazene, metonitazene, protonitazene, and other mu-opioid receptor 
agonists. These two benzimidazole-opioids bind to and act as agonists 
at the mu-opioid receptors.\20\ It is well established that substances 
that act as mu-opioid receptor agonists have a high potential for 
addiction and can induce dose-dependent respiratory depression.\21\

---------------------------------------------------------------------------

    Consistent with any mu-opioid receptor agonist, the potential 
health and safety risks for users of N-pyrrolidino metonitazene and N-
pyrrolidino protonitazene are high. N-Pyrrolidino metonitazene and N-
pyrrolidino protonitazene have been positively identified in forensic 
toxicology and post mortem cases. According to a public alert, N-
pyrrolidino protonitazene has been positively identified in 20 
medicolegal death investigations in the United States and United 
Kingdom as of August 2023. Of the cases, 16 occurred across seven 
States in the United States. Decedent ages ranged from mid-20s to mid-
70s. N-Pyrrolidino protonitazene was co-identified with additional 
novel psychoactive substances (70 percent), quinine (60 percent), other 
benzimidazole-opioids (55 percent), methamphetamine/cocaine (55 
percent), fentanyl (55 percent), xylazine (35 percent) and designer 
benzodiazepines (30 percent).\22\ Also, N-pyrrolidino metonitazene has 
been identified in six toxicology cases in the United States as of June 
2023. The introduction of potent synthetic opioids such as N-
pyrrolidino metonitazene and N-pyrrolidino protonitazene into the 
illicit market may serve as a portal to problematic opioid use for 
those seeking these powerful opioids. As documented by toxicology 
reports, polysubstance abuse remains common in fatalities associated 
with the abuse of some of these benzimidazole-opioids.

---------------------------------------------------------------------------

    The United States is currently experiencing an opioid epidemic, and 
the presence of synthetic opioids on the illicit drug market further 
exacerbates the problem. The trafficking and abuse of new synthetic 
opioids are deadly trends which pose imminent hazard to the public 
safety. Adverse health effects associated with the abuse of synthetic 
opioids and the continued evolution and increased popularity of these 
substances have been a serious concern in recent years. Because of the 
pharmacological similarities of N-pyrrolidino metonitazene and N-
pyrrolidino protonitazene to metonitazene and protonitazene, the use of 
these substances presents high risk of abuse and may negatively affect 
users and communities. The positive identification of these substances 
in toxicology cases is of serious concern to the public safety. Thus, 
N-pyrrolidino metonitazene and N-pyrrolidino protonitazene pose 
imminent hazard to public safety.

Finding of Necessity of Schedule I Placement To Avoid Imminent Hazard 
to Public Safety

    In accordance with 21 U.S.C. 811(h)(3), based on the available data 
and information summarized above, the uncontrolled manufacture, 
distribution, reverse distribution, importation, exportation, conduct 
of research and chemical analysis, possession, and abuse of N-
pyrrolidino metonitazene and N-pyrrolidino protonitazene pose imminent 
hazards to public safety. DEA is not aware of any currently accepted 
medical uses for these substances in the United States. A substance 
meeting the statutory requirements for temporary scheduling, found in 
21 U.S.C. 811(h)(1), may only be placed in schedule I. Substances in 
schedule I must have a high potential for abuse, no currently accepted 
medical use in treatment in the United States, and a lack of accepted 
safety for use under medical supervision. Available data and 
information for N-pyrrolidino metonitazene and N-pyrrolidino 
protonitazene indicate that these substances meet the three statutory 
criteria. As required by 21 U.S.C. 811(h)(4), the Administrator 
transmitted to the Assistant Secretary, via letter dated December 15, 
2023, notice of her intent to place N-pyrrolidino metonitazene and N-
pyrrolidino protonitazene in schedule I on a temporary basis. HHS had 
no objection to the temporary placement of these substances in schedule 
I.

Conclusion

    This notice of intent provides the 30-day notice pursuant to 21 
U.S.C. 811(h)(1) of DEA's intent to issue a temporary scheduling order. 
In accordance with 21 U.S.C. 811(h)(1) and (3), the Administrator 
considered available data and information, herein set forth the grounds 
for her determination that it is necessary to temporarily schedule N-
pyrrolidino metonitazene and N-pyrrolidino protonitazene in schedule I 
of the CSA, and finds that placement of these substances in schedule I 
is necessary to avoid an imminent hazard to the public safety.

[[Page 75983]]

    The temporary placement of N-pyrrolidino metonitazene and N-
pyrrolidino protonitazene in schedule I of the CSA will take effect 
pursuant to a temporary scheduling order, which will not be issued 
before October 17, 2024. Because the Administrator hereby finds this 
temporary scheduling order necessary to avoid an imminent hazard to the 
public safety, it will take effect on the date the order is published 
in the Federal Register and remain in effect for two years, with a 
possible extension of one year, pending completion of the regular 
(permanent) scheduling process.\23\ The Administrator intends to issue 
a temporary scheduling order as soon as possible after the expiration 
of 30 days from the date of publication of this document. Upon the 
temporary order's publication, N-pyrrolidino metonitazene and N-
pyrrolidino protonitazene will then be subject to the CSA's schedule I 
regulatory controls and to administrative, civil, and criminal 
sanctions applicable to their manufacture, distribution, reverse 
distribution, importation, exportation, research, conduct of 
instructional activities and chemical analysis, and possession.

    The CSA sets forth specific criteria for scheduling drugs or other 
substances. Regular scheduling actions in accordance with 21 U.S.C. 
811(a) are subject to formal rulemaking procedures ``on the record 
after opportunity for a hearing'' conducted pursuant to the provisions 
of 5 U.S.C. 556 and 557.\24\ The regular scheduling process of formal 
rulemaking affords interested parties appropriate process and the 
government any additional relevant information needed to make a 
determination. Final decisions that conclude the regular scheduling 
process of formal rulemaking are subject to judicial review.\25\

Regulatory Analyses

    The CSA provides for expedited temporary scheduling actions where 
necessary to avoid an imminent hazard to the public safety. Under 21 
U.S.C. 811(h)(1), the Administrator, as delegated by the Attorney 
General, may, by order, temporarily place substances in schedule I. 
Such orders may not be issued before the expiration of 30 days from: 
(1) The publication of a notice in the Federal Register of the intent 
to issue such order and the grounds upon which such order is to be 
issued, and (2) the date that notice of the proposed temporary 
scheduling order is transmitted to the Assistant Secretary, as 
delegated by the Secretary of HHS.\27\
---------------------------------------------------------------------------

    \27\ 21 U.S.C. 811(h)(1).
---------------------------------------------------------------------------

    Inasmuch as section 811(h) directs that temporary scheduling 
actions be issued by order and sets forth the procedures by which such 
orders are to be issued, including the requirement to publish in the 
Federal Register a notice of intent, the notice-and-comment 
requirements of section 553 of the Administrative Procedure Act (APA), 
5 U.S.C. 553, do not apply to this notice of intent. The APA expressly 
differentiates between orders and rules, as it defines an ``order'' to 
mean a ``final disposition, whether affirmative, negative, injunctive, 
or declaratory in form, of an agency in a matter other than rule 
making.'' \28\ (Emphasis added). This contrasts with permanent 
scheduling actions, which are subject to formal rulemaking procedures 
done ``on the record after opportunity for a hearing,'' and final 
decisions that conclude the scheduling process and are subject to 
judicial review. 21 U.S.C. 811(a) and 877. The specific language chosen 
by Congress indicates its intent that DEA issue orders instead of 
proceeding by rulemaking when temporarily scheduling substances. Given 
that Congress specifically requires the Administrator (as delegated by 
the Attorney General) to follow rulemaking procedures for other kinds 
of scheduling actions, see 21 U.S.C. 811(a), it is noteworthy that, in 
section 811(h)(1), Congress authorized the issuance of temporary 
scheduling actions by order rather than by rule.
---------------------------------------------------------------------------

    \28\ 5 U.S.C. 551(6).
---------------------------------------------------------------------------

    Even assuming that this notice of intent is subject to section 553 
of the APA, the Administrator finds that there is good cause to forgo 
its notice-and-comment requirements, as any further delays in the 
process for issuing temporary scheduling orders would be impracticable 
and contrary to the public interest given the manifest urgency to avoid 
an imminent hazard to the public safety.
    Although DEA believes this notice of intent to issue a temporary 
scheduling order is not subject to the notice-and-comment requirements 
of section 553 of the APA, DEA notes that in accordance with 21 U.S.C. 
811(h)(4), the Administrator took into consideration comments submitted 
by the Assistant Secretary in response to the notices that DEA 
transmitted to the Assistant Secretary pursuant to such subsection.
    Further, DEA believes that this temporary scheduling action is not 
a ``rule'' as defined by 5 U.S.C. 601(2), and, accordingly, is not 
subject to the requirements of the Regulatory Flexibility Act (RFA). 
The requirements for the preparation of an initial regulatory 
flexibility analysis in 5 U.S.C. 603(a) are not applicable where, as 
here, DEA is not required by section 553 of the APA or any other law to 
publish a general notice of proposed rulemaking. As discussed above, 
DEA is issuing this notice of intent pursuant to DEA's authority to 
issue a temporary scheduling order. 21 U.S.C. 811(h)(1). Therefore, in 
this instance, since DEA believes this temporary scheduling action is 
not a ``rule,'' it is not subject to the requirements of the RFA when 
issuing this temporary action.
    In accordance with the principles of Executive Orders (E.O.) 12866 
and 13563, this action is not a significant regulatory action. E.O. 
12866 directs agencies to assess all costs and benefits of available 
regulatory alternatives and, if regulation is necessary, to select 
regulatory approaches that maximize net benefits (including potential 
economic, environmental, public health, and safety effects; 
distributive impacts; and equity). E.O. 13563 is supplemental to and 
reaffirms the principles, structures, and definitions governing 
regulatory review as established in E.O. 12866. E.O. 12866, sec. 3(f), 
as amended by E.O. 14094, sec. 1(b), provides the definition of a 
``significant regulatory action,'' requiring review by the Office of 
Management and Budget. Because this is not a rulemaking action, this is 
not a significant regulatory action as defined in section 3(f) of E.O. 
12866.
    This action will not have substantial direct effects on the States, 
on the relationship between the National Government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government. Therefore, in accordance with E.O. 13132, it is 
determined that this action does not have sufficient federalism 
implications to warrant the preparation of a Federalism Assessment.
