[Docket No. DEA-989]


Schedules of Controlled Substances: Temporary Placement of 
Etizolam, Flualprazolam, Clonazolam, Flubromazolam, and Diclazepam in 
Schedule I

AGENCY: Drug Enforcement Administration, Department of Justice.

ACTION: Temporary amendment; temporary scheduling order.

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

SUMMARY: The Administrator of the Drug Enforcement Administration is 
issuing this temporary order to schedule five synthetic benzodiazepine 
substances: etizolam, flualprazolam, clonazolam, flubromazolam, and 
diclazepam, in schedule I of the Controlled Substances Act. This action 
is based on a finding by the Administrator that the placement of these 
five substances in schedule I is necessary to avoid imminent hazard to 
the public safety. As a result of this order, the regulatory controls 
and administrative, civil, and criminal sanctions applicable to 
schedule I controlled substances will be imposed on persons who handle 
(manufacture, distribute, reverse distribute, import, export, engage in 
research, conduct instructional activities or chemical

[[Page 48113]]

analysis with, or possess) or propose to handle these five specified 
controlled substances.

DATES: This temporary scheduling order is effective July 26, 2023, 
until July 26, 2025. If this order is extended or made permanent, DEA 
will publish a document in the Federal Register.

SUPPLEMENTARY INFORMATION: The Drug Enforcement Administration (DEA) 
issues a temporary scheduling order \1\ (in the form of a temporary 
amendment) to add the following five substances, including their salts, 
isomers, and salts of isomers, whenever the existence of such salts, 
isomers, and salts of isomers 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 order adheres to the 
statutory language of 21 U.S.C. 811(h), which refers to a 
``temporary scheduling order.'' No substantive change is intended.

benzo[e][1,4]diazepin-2-one (commonly known as diclazepam).

Legal Authority

    The CSA provides the Attorney General, as delegated to the 
Administrator of DEA (Administrator) pursuant to 28 CFR 0.100, with the 
authority to temporarily place a substance in schedule I of the CSA for 
two years without regard to the requirements of 21 U.S.C. 811(b), if 
the Administrator finds that such action is necessary to avoid an 
imminent hazard to public safety. 21 U.S.C. 811(h)(1). 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 Administrator may extend the temporary scheduling for up to 
one year. 21 U.S.C. 811(h)(2).
    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, and 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. 21 U.S.C. 811(h)(1); 21 CFR part 1308.

Background

    The CSA requires the Administrator to notify the Secretary of the 
Department of Health and Human Services (HHS) of an intent to place a 
substance in schedule I of the CSA temporarily (i.e., to issue a 
temporary scheduling order). 21 U.S.C. 811(h)(4). The Administrator 
transmitted the required notice to the Assistant Secretary for Health 
of HHS (Assistant Secretary),\2\ by letter dated October 27, 2021, 
regarding etizolam, flualprazolam, clonazolam, flubromazolam, and 
diclazepam. The Assistant Secretary responded to this notice by letter 
dated January 3, 2022, and advised that, based on a review by the Food 
and Drug Administration (FDA), there are currently no investigational 
new drug applications (INDs) or approved new drug applications (NDA) 
for etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam. 
The Assistant Secretary also stated that HHS had no objection to the 
temporary placement of these substances in schedule I.
---------------------------------------------------------------------------

    \2\ 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.
---------------------------------------------------------------------------

    DEA has taken into consideration the Assistant Secretary's comments 
as required by subsection 811(h)(4). DEA has found that the control of 
these five benzodiazepines in schedule I on a temporary basis is 
necessary to avoid an imminent hazard to the public safety. Etizolam, 
flualprazolam, clonazolam, flubromazolam, and diclazepam 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 five 
benzodiazepine substances.
    As required by 21 U.S.C. 811(h)(1)(A), DEA published a notice of 
intent (NOI) to temporarily schedule etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam on December 23, 2022. 87 FR 
78887. That NOI discussed findings from DEA's three-factor analysis 
dated October 2022, which DEA made available on www.regulations.gov.
    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. 21 U.S.C. 811(h)(3). Consideration of 
these factors includes any information indicating actual abuse, 
diversion from legitimate channels, and clandestine importation, 
manufacture, or distribution of these substances. 21 U.S.C. 811(h)(3).
    Substances meeting the statutory requirements for temporary 
scheduling may only be placed in schedule I. 21 U.S.C. 811(h)(1). 
Substances in schedule I are those that have 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. 21 
U.S.C. 812(b)(1).
    DEA's October 2022 three-factor analysis and the Assistant 
Secretary's January 3, 2022 letter are available in their entirety

action at www.regulations.gov.

Five Benzodiazepine Substances: Etizolam, Flualprazolam, Clonazolam, 
Flubromazolam, and Diclazepam

    The dramatic increase in trafficking and abuse associated with 
novel psychoactive substances (NPS) of the benzodiazepine class, also 
known as designer benzodiazepines, in the United States has become a 
national public health concern in recent years. The availability of NPS 
benzodiazepine substances in the illicit drug market continues to pose 
an imminent hazard to the public safety. The Centers for Disease 
Control and Prevention (CDC) highlights this issue in their Morbidity 
and Mortality Weekly Report (MMWR) published on August 27, 2021.\3\ CDC 
indicated that from April 2019 to June 2020 prescription and illicit 
benzodiazepine-involved overdose deaths increased by 21.8 percent and 
519.6 percent respectively. Additionally, benzodiazepines were involved 
in nearly 7,000 overdose

[[Page 48114]]

deaths in 23 states from January 2019 to June 2020, accounting for 17 
percent of all drug overdose deaths. Adverse health effects associated 
with the abuse of such substances, their continued evolution, and 
increased popularity of these substances have been a serious concern in 
recent years.

2019-2020. Vol. 70, No. 34. August 27, 2021.
---------------------------------------------------------------------------

    The increase in the co-use of opioids with designer benzodiazepines 
has become a particular concern as the United States continues to 
experience an unprecedented epidemic of opioid misuse and abuse.\4\ 
CDC's 2021 MMWR further states that between January and June 2020, 92.7 
percent of benzodiazepine-involved deaths also involved opioids and 
66.7 percent involved illicitly manufactured fentanyl. The combination 
of benzodiazepines with opioids substantially enhances the potential 
for lethality. Etizolam, flualprazolam, clonazolam, flubromazolam, and 
diclazepam are benzodiazepine substances recently identified on the 
illicit drug market in the United States.

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

    The abuse of etizolam, flualprazolam, clonazolam, flubromazolam, 
and diclazepam has been associated with fatalities in recent years in 
the United States. The positive identification of these five substances 
in post-mortem cases is a serious concern to the public safety. 
Additionally, law enforcement data indicate that the substances at 
issue here have significant presence in the illicit drug market found 
in the United States. In light of the law enforcement encounters and 
fatalities associated with the abuse of etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam, these substances pose an 
imminent hazard to public safety.
    Available data and information for etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam, summarized below, indicate 
that these substances have high potential for abuse, no currently 
accepted medical use in treatment in the United States, and 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-989.

Factor 4. History and Current Pattern of Abuse

    The chemical synthesis of etizolam, flualprazolam, clonazolam, 
flubromazolam, and diclazepam was previously reported in the scientific 
literature; however, the research did not lead to any medically 
approved products in the United States. Since 2012, synthetic drugs 
belonging to the benzodiazepine class have begun to emerge in the 
illicit drug market as evidenced by the identification of these drugs 
in forensic drug exhibits reported to the National Forensic Laboratory 
Information System (NFLIS-Drug) \5\ and toxicology samples. Beginning 
in 2012, etizolam emerged on the illicit synthetic drug market as 
evidenced by its identification in drug seizures in the United States.
---------------------------------------------------------------------------

    \5\ NFLIS-Drug represents an important resource in monitoring 
illicit drug trafficking, including the diversion of legally 
manufactured pharmaceuticals into illegal markets. NFLIS-Drug is a 
comprehensive information system that includes data from forensic 
laboratories that handle more than 96 percent of an estimated 1.0 
million distinct annual state and local drug analysis cases. NFLIS-
Drug includes drug chemistry results from completed analyses only. 
While NFLIS-Drug data is not direct evidence of abuse, it can lead 
to an inference that a drug has been diverted and abused. See 76 FR 
77330, 77332, Dec. 12, 2011.
---------------------------------------------------------------------------

    In recent years, there has been a rise in the recreational use of 
etizolam. As evidenced by their identification in NFLIS-Drug, 
diclazepam emerged in the United States' illicit drug market in 2014, 
flubromazolam and clonazolam in 2015, and flualprazolam in 2017. While 
these substances are not approved for medical use in the United States, 
etizolam is approved for medical use in Italy, India, and Japan.\6\ In 
a letter dated January 3, 2022, the Assistant Secretary informed DEA 
that there are no INDs or FDA-approved NDAs for etizolam, 
flualprazolam, clonazolam, flubromazolam, and diclazepam in the United 
States. Hence, there are no legitimate channels for these substances as 
marketed drug products in the United States. These five benzodiazepine 
substances are likely to be abused in the same manner as other sedative 
hypnotics. They have been identified in tablet form, as white to beige 
powders, or in liquid forms, typically of unknown purity or 
concentration.
---------------------------------------------------------------------------

    \6\ Although there is no evidence suggesting that etizolam, 
flualprazolam, clonazolam, flubromazolam, or diclazepam has a 
currently accepted medical use in treatment in the United States, it 
bears noting that a drug cannot be found to have such medical use 
unless DEA concludes that it satisfies a five-part test. 
Specifically, with respect to a drug that has not been approved by 
FDA, to have a currently accepted medical use in treatment in the 
United States, all of the following must be demonstrated: 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. 57 FR 10499 (1992), pet. for rev. denied, Alliance for 
Cannabis Therapeutics v. DEA, 15 F.3d 1131, 1135 (D.C. Cir. 1994).
---------------------------------------------------------------------------

    Based on data from NFLIS-Drug, law enforcement often encounters 
etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam in 
counterfeit pills, liquid, or powder form. Substances often found in 
combination with some of these benzodiazepines include substances of 
abuse such as heroin (schedule I), fentanyl (schedule II), substances 
structurally related to fentanyl, other benzodiazepines (both FDA-
approved schedule IV benzodiazepines and other novel non-controlled 
benzodiazepines), and tramadol (schedule IV). Evidence suggests that 
individuals are using these substances to obtain ``legal highs'' \7\ or 
to self-medicate. Information gathered from case histories and autopsy 
findings shows that deaths involving etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam were predominantly associated 
with poly-drug use.
---------------------------------------------------------------------------

    \7\ Substances used as ``legal highs'' are psychoactive 
substances that are not controlled under the CSA, but can be used to 
obtain a desired psychoactive effect.
---------------------------------------------------------------------------

Factor 5. Scope, Duration, and Significance of Abuse

    Etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam 
are novel benzodiazepines and evidence suggests they are abused for 
their sedative effects (see Factor 6). In death investigations 
involving polysubstance use, the co-appearance of benzodiazepines and 
opioids in toxicological analysis was common. Between August 2019 and 
January 2020, flualprazolam and etizolam were identified in seven and 
six postmortem blood specimens, respectively, out of 18 deaths 
associated with the abuse of isotonitazene, a schedule I opioid that 
was recently controlled.\8\ These cases corresponded to four states--
Illinois (9), Indiana (7), Minnesota (1), and Wisconsin (1). Most (12) 
of the decedents were male. The ages ranged from 24 to 66 years old 
with an average age of 41 years.\9\

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

    In another recent publication, 20 forensic postmortem cases were 
reviewed and analyzed for the presence of metonitazine, NPS 
benzodiazepines, and opioids. Clonazolam was positively identified in 
four cases, etizolam in two cases, flualprazolam in two cases, and

[[Page 48115]]

pyrazolam in one case.\10\ Law enforcement encounters of etizolam, 
flualprazolam, clonazolam, flubromazolam, and diclazepam as reported to 
NFLIS-Drug include 34,781 drug reports since 2014 (queried 01/13/2022). 
NFLIS-Drug registered three encounters of etizolam in 2012 (first year 
of encounter) and 3,022 reports in 2021. Flualprazolam was first 
encountered in 2017 when one report was identified in NFLIS-Drug, and 
then in 2021, 1,305 encounters were reported. A similar trend was seen 
with clonazolam. During 2015 (its first year of encounter), 57 cases 
were reported in NFLIS-Drug, while 3,994 drug reports were identified 
in 2021. NFLIS-Drug registered five diclazepam encounters in 2014 (its 
first year of encounter) and 54 encounters in 2021. Flubromazolam 
encounters totaled 14 in 2015 (its first year of encounter) and 414 in 
2021.

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

    The population likely to abuse etizolam, flualprazolam, clonazolam, 
flubromazolam, and diclazepam appears to be the same as those abusing 
prescription benzodiazepines, barbiturates, and other sedative hypnotic 
substances. This is evidenced by drug user reports associated with 
these substances. Because abusers of etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam 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 benzodiazepines have been demonstrated and 
are well-characterized.\11\ According to the most recent data from the 
National Survey on Drug Use and Health (NSDUH),\12\ as of 2020, an 
estimated 4.8 million people aged 12 years or older misused 
prescription benzodiazepines in the past year. This included 1.1 
million young adults aged 18 to 25, 3.5 million adults aged 26 or 
older, and 157,000 adolescents aged 12 to 17. This population abusing 
prescription benzodiazepines is likely to be at risk of abusing 
etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam. 
Individuals who initiate use of these five substances (i.e., use a drug 
for the first time) are likely to be at risk of developing substance 
use disorder, overdose, and death at rates similar to that of other 
sedative hypnotics (e.g., alprazolam, etc.). Law enforcement or 
toxicology reports demonstrate that the five substances at issue are 
being distributed and abused.

    \12\ The National Survey on Drug Use and Health (NSDUH), 
formerly known as the National Household Survey on Drug Abuse 
(NHSDA), is conducted annually by the Department of Health and Human 
Services Substance Abuse and Mental Health Services Administration 
(SAMHSA). It is the primary source of estimates of the prevalence 
and incidence of nonmedical use of pharmaceutical drugs, illicit 
drugs, alcohol, and tobacco use in the United States. The survey is 
based on a nationally representative sample of the civilian, non-
institutionalized population 12 years of age and older. The survey 
excludes homeless people who do not use shelters, active military 
personnel, and residents of institutional group quarters such as 
jails and hospitals. The NSDUH provides yearly national and state 
level estimates of drug abuse, and includes prevalence estimates by 
lifetime (i.e., ever used), past year, and past month abuse or 
dependence. The 2020 NSDUH annual report is available at https://www.samhsa.gov/data/ (last accessed February 8, 2022).
---------------------------------------------------------------------------

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

    The increase in benzodiazepine-related overdose deaths in the 
United States has been exacerbated recently by the availability of NPS 
benzodiazepines in the illicit drug market. Etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam have been described as 
derivatives of other known benzodiazepines, each possessing various 
degrees of potency. Evidence suggests these substances are being abused 
for their sedative/hypnotic effects (see DEA 3-Factor Analysis). Public 
health risks associated with the five substances at issue here relate 
to their pharmacological similarities with known benzodiazepines. Thus, 
risk to the public health is associated with adverse reactions in 
humans, which are expected to include CNS depressant-like effects, such 
as slurred speech, ataxia, altered mental state, and respiratory 
depression.
    Etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam 
have been increasingly identified in toxicology reports, death 
investigations, and driving under the influence of drugs (DUID) cases 
since their first appearance in law enforcement seizures. According to 
the Center for Forensic Science Research and Education (CFSRE), a non-
profit organization in collaboration with the Department of Justice and 
CDC between 2020 and 2021, etizolam was the most identified NPS 
benzodiazepine accounting for 697 total toxicology cases in 2020, many 
of which were co-identified with fentanyl. In 2021, etizolam was 
identified in 1,012 toxicology cases, while flualprazolam, clonazolam, 
flubromazolam, and diclazepam were associated with 432, 331, 170, and 
four toxicology cases, respectively (CSFRE Quarterly Trend Reports: NPS 
Benzodiazepines in the United States).
    Death investigations associated with four of the five NPS 
benzodiazepines at issue here have increased in recent years. In a 2021 
publication by the Orange County Crime Lab in Santa Ana, California, 
flualprazolam was identified as serving a contributory role in the 
death of 13 of 24 cases analyzed in the study.\13\ In another recently 
published study, between August 2019 and January 2020, flualprazolam 
and etizolam were identified in seven and six postmortem blood 
specimens respectively, out of 18 deaths associated with the abuse of 
isotonitazene, a schedule I opioid.\14\ Then, a study published in 2021 
which compiled data from 254 reports published between 2008 and 2021, 
identified: 33 deaths associated with etizolam, 20 flualprazolam-
related deaths, six emergency department (ED) visits associated with 
clonazolam, 14 flubromazolam-related ED visits, and one death, 12 DUID 
cases, and four ED visits associated with diclazepam.\15\ Additionally, 
in 2020, the European Monitoring Centre for Drugs and Drug Addiction 
reported 34 deaths associated with diclazepam use, which were 
determined through the analysis of biological samples.\16\ Furthermore, 
the National Poison Data System reported that between January 2014 and 
December 2017, clonazolam was the second most common benzodiazepine 
associated with poison control center calls, accounting for 50 
incidents.\17\

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

    Impaired driving is another risk factor associated with the use and 
abuse of etizolam, flualprazolam, clonazolam, flubromazolam, and 
diclazepam. In a recent published report from the

[[Page 48116]]

Sedgwick County Regional Forensic Science Center in Wichita, Kansas, 12 
DUID case samples were analyzed. Etizolam was positively identified in 
three cases, while flubromazolam was identified in nine of these 
cases.\18\ In a 2021 publication, similar involvement of flubromazolam 
in drug-impaired driving was reported in Canada where flubromazolam was 
detected in 10 percent of 113 case samples.\19\ Diclazepam has also 
been implicated in DUID cases domestically and internationally. In a 
Norwegian study conducted between July 2013 and May 2016, diclazepam 
was identified in 15 of 77 analyzed samples taken from impaired drivers 
and individuals involved in other criminal offenses. Then, in 2019, a 
study of Norwegian drivers was conducted using 575 samples taken 
predominantly from intoxicated drivers and individuals who committed 
other criminal offenses.\20\ Notably, 334 samples were found to contain 
diclazepam. Additionally, in a 2021 publication from Orange County 
Crime Laboratory in Santa Ana, California, researchers identified 22 
samples that tested positive for flualprazolam in samples obtained from 
DUID investigations between August 2018 and September 2020.\21\

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/or abuse of 
etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam 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, 
21 U.S.C. 811(h)(1), may only be placed in schedule I. Substances in 
schedule I are those that 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 etizolam, flualprazolam, clonazolam, flubromazolam, and 
diclazepam indicate that these five synthetic benzodiazepine substances 
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.
    As required by 21 U.S.C. 811(h)(4), the Administrator transmitted 
to the Assistant Secretary for Health, via a letter dated October 27 
2021, notice of her intent to place etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam in schedule I on a temporary 
basis. HHS had no objection to the temporary placement of these 
substances in schedule I.
    DEA subsequently published a NOI on December 23, 2022. 87 FR 78887.

Conclusion

    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 place 
etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam in 
schedule I of the CSA and finds that such placement is necessary to 
avoid an imminent hazard to the public safety.
    This temporary order scheduling these substances will be effective 
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. 21 U.S.C. 
811(h)(1) and (2).
    The CSA sets forth specific criteria for scheduling drugs or other 
substances. Permanent scheduling actions in accordance with 21 U.S.C. 
811(a) are subject to formal rulemaking procedures done ``on the record 
after opportunity for a hearing'' conducted pursuant to the provisions 
of 5 U.S.C. 556 and 557. 21 U.S.C. 811. The permanent scheduling 
process of formal rulemaking affords interested parties with an 
appropriate process and the government any additional relevant 
information needed to make determinations. Final decisions that 
conclude the permanent scheduling process of formal rulemaking are 
subject to judicial review. 21 U.S.C. 877. Temporary scheduling orders 
are not subject to judicial review. 21 U.S.C. 811(h)(6).

Requirements for Handling

    Upon the effective date of this temporary order, etizolam, 
flualprazolam, clonazolam, flubromazolam, and diclazepam will be 
subject to the regulatory controls and administrative, civil, and 
criminal sanctions applicable to the manufacture, distribution, reverse 
distribution, importation, exportation, possession of, and engagement 
in research and conduct of instructional activities or chemical 
analysis with, schedule I controlled substances, including the 
following:
    1. Registration. Any person who handles (possesses, manufactures, 
distributes, reverse distributes, imports, exports, engages in 
research, or conducts instructional activities or chemical analysis 
with) or desires to handle, etizolam, flualprazolam, clonazolam, 
flubromazolam, and diclazepam must be registered with DEA to conduct 
such activities, pursuant to 21 U.S.C. 822, 823, 957, and 958, and in 
accordance with 21 CFR parts 1301 and 1312, as of July 26, 2023. Any 
person who currently handles etizolam, flualprazolam, clonazolam, 
flubromazolam, and diclazepam and is not registered with DEA must 
submit an application for registration and may not continue to handle 
etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam as 
of July 26, 2023, unless DEA has approved that application for 
registration pursuant to 21 U.S.C. 822, 823, 957, and 958, and in 
accordance with 21 CFR parts 1301 and 1312. Retail sales of schedule I 
controlled substances to the general public are not allowed under the 
CSA. Possession of any quantity of these substances in a manner not 
authorized by the CSA on or after July 26, 2023 is unlawful, and those 
in possession of any quantity of these substances may be subject to 
prosecution pursuant to the CSA.
    2. Disposal of stocks. Any person who does not desire or is unable 
to obtain a schedule I registration to handle etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam must surrender all currently 
held quantities of these five substances.
    3. Security. Etizolam, flualprazolam, clonazolam, flubromazolam, 
and diclazepam are subject to schedule I security requirements and must 
be handled in accordance with 21 CFR 1301.71-1301.93, as of July 26, 
2023.
    4. Labeling and Packaging. All labels, labeling, and packaging for 
commercial containers of etizolam, flualprazolam,

[[Page 48117]]

clonazolam, flubromazolam, and diclazepam must comply with 21 U.S.C. 
825 and 958(e) and 21 CFR part 1302. Current DEA registrants will have 
30 calendar days from July 26, 2023 to comply with all labeling and 
packaging requirements.
    5. Inventory. Every DEA registrant who possesses any quantity of 
etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam on 
the effective date of this order must take an inventory of all stocks 
of these substances on hand pursuant to 21 U.S.C. 827 and 958, and in 
accordance with 21 CFR 1304.03, 1304.04, and 1304.11. Current DEA 
registrants will have 30 calendar days from the effective date of this 
order to comply with all inventory requirements. After the initial 
inventory, every DEA registrant must take an inventory of all 
controlled substances (including etizolam, flualprazolam, clonazolam, 
flubromazolam, and diclazepam) on hand on a biennial basis pursuant to 
21 U.S.C. 827 and 958 and in accordance with 21 CFR 1304.03, 1304.04, 
and 1304.11.
    6. Records. All DEA registrants must maintain records with respect 
to etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam 
pursuant to 21 U.S.C. 827 and 958(e) and in accordance with 21 CFR 
parts 1304, 1312, and 1317, and section 1307.11. Current DEA 
registrants authorized to handle these five substances shall have 30 
calendar days from the effective date of this order to comply with all 
recordkeeping requirements.
    7. Reports. All DEA registrants must submit reports with respect to 
etizolam, flualprazolam, clonazolam, flubromazolam, and diclazepam 
pursuant to 21 U.S.C. 827 and in accordance with 21 CFR parts 1304, 
1312, and 1317, and sections 1301.74(c) and 1301.76(b), as of July 26, 
2023. Manufacturers and distributors must also submit reports regarding

accordance with 21 CFR part 1303, as of July 26, 2023.
    11. Liability. Any activity involving etizolam, flualprazolam, 
clonazolam, flubromazolam, and diclazepam not authorized by or in 
violation of the CSA, occurring as of July 26, 2023, is unlawful and 
may subject the person to administrative, civil, and/or criminal 
sanctions.

Regulatory Matters

    The CSA provides for expedited temporary scheduling actions where 
necessary to avoid imminent hazards to the public safety. Under 21 
U.S.C. 811(h), the Administrator, as delegated by the Attorney General, 
may, by order, temporarily schedule 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 for Health of HHS, as delegated 
by the Secretary of HHS. 21 U.S.C. 811(h)(1).
    Inasmuch as section 811(h) directs that temporary scheduling 
actions be issued by order (as distinct from a rule) 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, which are applicable to rulemaking, 
do not apply to this temporary scheduling order. 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.'' 5 U.S.C. 551(6) (emphasis added). 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), Congress authorized the issuance of 
temporary scheduling actions by order rather than by rule.
    Alternatively, even if this action was 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 
imminent hazards to public safety.
    Although DEA believes this 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 notice 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. 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.
    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 classifies a 
``significant regulatory action,'' requiring review by the Office of 
Management and Budget, as any regulatory action that is likely to 
result in a rule that may: (1) Have an annual effect on the economy of 
$100 million or more or adversely affect in a material way the economy; 
a sector of the economy; productivity; competition; jobs; the 
environment; public health or safety; or State, local, or tribal 
governments or communities; (2) create a serious inconsistency or 
otherwise interfere with an action taken or planned by another agency; 
(3) materially alter the budgetary impact of entitlements, grants, user 
fees, or loan

[[Page 48118]]

programs, or the rights and obligations of recipients thereof; or (4) 
raise novel legal or policy issues arising out of legal mandates, the 
President's priorities, or the principles set forth in the E.O. 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 
(Federalism), it is determined that this action does not have 
sufficient federalism implications to warrant the preparation of a 
Federalism Assessment.
