DEPARTMENT OF JUSTICE

Drug Enforcement Administration

21 CFR Part 1308

[Docket No. DEA-1142]


Schedules of Controlled Substances: Placement of Ethylphenidate 
in Schedule I

AGENCY: Drug Enforcement Administration, Department of Justice.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: The Drug Enforcement Administration proposes placing the 
substance ethylphenidate (chemical name: ethyl 2-phenyl-2-(piperidin-2-
yl)acetate), including its salts, isomers, and salts of isomers, in 
schedule I of the Controlled Substances Act. This action is being 
taken, in part, to enable the United States to meet its obligations 
under the 1971 Convention on Psychotropic Substances. If finalized, 
this action would 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 
ethylphenidate.

    In accordance with 21 U.S.C. 811 and 812, the purpose of a hearing 
would be to determine whether ethylphenidate meets the statutory 
criteria for placement in schedule I.

Legal Authority

    The CSA provides that proceedings for the issuance, amendment, or 
repeal of the scheduling of any drug or other substance may be 
initiated by the Attorney General (delegated to the Administrator of 
DEA pursuant to 28 CFR 0.100) on his own motion.\4\ This proposed 
action is supported by a recommendation from the Assistant Secretary 
for Health of the Department of Health and Human Services (HHS).
---------------------------------------------------------------------------

    \4\ 21 U.S.C. 811(a).
---------------------------------------------------------------------------

    In addition, the United States is a party to the 1971 United 
Nations Convention on Psychotropic Substances (1971 Convention), 
February 21, 1971, 32 U.S.T. 543, 1019 U.N.T.S. 175, as amended. 
Procedures respecting changes in drug schedules under the 1971 
Convention are governed domestically by 21 U.S.C. 811(d)(2)-(4). When 
the United States receives notification of a scheduling decision 
pursuant to Article 2 of the 1971 Convention indicating that a drug or 
other substance has been added to a schedule specified in the 
notification, the Secretary of HHS (Secretary),\5\ after consultation 
with the Attorney General, shall first determine whether existing legal 
controls under subchapter I of the Controlled Substances Act (CSA) and 
the Federal Food, Drug, and Cosmetic Act meet the requirements of the 
schedule specified in the notification with respect to the specific 
drug or

[[Page 65332]]

substance.\6\ In the event that the Secretary did not so consult with 
the Attorney General, and the Attorney General did not issue a 
temporary order, as provided under 21 U.S.C. 811(d)(4), the procedures 
for permanent scheduling set forth in 21 U.S.C. 811(a) and (b) control. 
Pursuant to 21 U.S.C. 811(a)(1), the Attorney General (as delegated to 
the Administrator of DEA) may, by rule, add to such a schedule or 
transfer between such schedules any drug or other substance, if he 
finds that such drug or other substance has a potential for abuse, and 
makes with respect to such drug or other substance the findings 
prescribed by 21 U.S.C. 812(b) for the schedule in which such drug or 
other substance is to be placed.
---------------------------------------------------------------------------

    \5\ As discussed in a memorandum of understanding entered into 
by the FDA and the National Institute on Drug Abuse (NIDA), FDA acts 
as the lead agency within HHS in carrying out the Secretary's 
scheduling responsibilities under the CSA, with the concurrence of 
NIDA. 50 FR 9518 (March 8, 1985). The Secretary has delegated to the 
Assistant Secretary for Health of HHS the authority to make domestic 
drug scheduling recommendations. 58 FR 35460 (July 1, 1993).
    \6\ 21 U.S.C. 811(d)(3).
---------------------------------------------------------------------------

Background

    Ethylphenidate is a central nervous system (CNS) stimulant and 
shares structural and pharmacological similarities with other schedule 
II stimulants such as methylphenidate. On April 21, 2017, the 
Secretary-General of the United Nations advised the Secretary of State 
of the United States that during its 60th session, on March 16, 2017, 
the Commission on Narcotic Drugs voted to place ethyl 2-phenyl-2-
(piperidin-2-yl)acetate (ethylphenidate) in Schedule II of the 1971 
Convention (CND Dec/60/7). Because the procedures in 21 U.S.C. 
811(d)(3) and (4) for consultation and issuance of a temporary order 
for ethylphenidate, discussed in the above legal authority section, 
were not followed, DEA is utilizing the procedures for permanent 
scheduling set forth in 21 U.S.C. 811(a) and (b) to control 
ethylphenidate. Such scheduling would satisfy the United States' 
international obligations.
    Article 2, paragraph 7(b), of the 1971 Convention sets forth the 
minimum requirements that the United States must meet when a substance 
has been added to Schedule II of the 1971 Convention. Pursuant to the 
1971 Convention, the United States must require licenses for the 
manufacture, export and import, and distribution of ethylphenidate. 
This license requirement is accomplished by the CSA's registration 
requirement as set forth in 21 U.S.C. 822, 823, 957, 958 and in ance 
with 21 CFR parts 1301 and 1312. In addition, the United States must 
adhere to specific export and import provisions set forth in the 1971 
Convention. This requirement is accomplished by the CSA's export and 
import provisions established in 21 U.S.C. 952, 953, 957, 958 and in 
accordance with 21 CFR part 1312. Likewise, under Article 13, 
paragraphs 1 and 2, of the 1971 Convention, a party to the 1971 
Convention may notify through the UN Secretary-General another party 
that it prohibits the importation of a substance in Schedule II, III, 
or IV of the 1971 Convention. If such notice is presented to the United 
States, the United States shall take measures to ensure that the named 
substance is not exported to the notifying country. This requirement is 
also accomplished by the CSA's export provisions mentioned above. Under 
Article 16, paragraph 4, of the 1971 Convention, the United States is 
required to provide annual statistical reports to the International 
Narcotics Control Board (INCB). Using INCB Form P, the United States 
shall provide the following information: (1) in regard to each 
substance in Schedule I and II of the 1971 Convention, quantities 
manufactured in, exported to, and imported from each country or region 
as well as stocks held by manufacturers; (2) in regard to each 
substance in Schedule II and III of the 1971 Convention, quantities 
used in the manufacture of exempt preparations; and (3) in regard to 
each substance in Schedule II-IV of the 1971 Convention, quantities 
used for the manufacture of non-psychotropic substances or products. 
Lastly, under Article 2 of the 1971 Convention, the United States must 
adopt measures in accordance with Article 22 to address violations of 
any statutes or regulations that are adopted pursuant to its 
obligations under the 1971 Convention. Persons acting outside the legal 
framework established by the CSA are subject to administrative, civil, 
and/or criminal action; therefore, the United States complies with this 
provision.
    DEA notes that there are differences between the schedules of 
substances in the 1971 Convention and the CSA. The CSA has five 
schedules (schedules I-V) with specific criteria set forth for each 
schedule. Schedule I is the only possible schedule in which a drug or 
other substance may be placed if it has high potential for abuse and no 
currently accepted medical use in treatment in the United States. See 
21 U.S.C. 812(b). In contrast, the 1971 Convention has four schedules 
(Schedules I-IV) but does not have specific criteria for each schedule. 
The 1971 Convention simply defines its four schedules, in Article 1, to 
mean the correspondingly numbered lists of psychotropic substances 
annexed to the Convention, and altered in accordance with Article 2.

Proposed Determination To Schedule Ethylphenidate

    On April 3, 2019, the Drug Enforcement Administration (DEA) 
requested that the Department of Health and Human Services (HHS) 
conduct a scientific and medical evaluation and provide a scheduling 
recommendation for ethylphenidate. On October 26, 2020, HHS provided 
DEA a scientific and medical evaluation (dated August 25, 2020) 
entitled ``Basis for the recommendation to place ethylphenidate in 
schedule I of the Controlled Substances Act'' and a scheduling 
recommendation. Pursuant to 21 U.S.C. 811(b), following consideration 
of the eight-factors and findings related to the substance's abuse 
potential, legitimate medical use, safety, and dependence liability, 
HHS recommended that ethylphenidate be controlled in schedule I of the 
CSA under 21 U.S.C. 812(b). Upon receipt of the scientific and medical 
evaluation and scheduling recommendation from HHS, DEA reviewed the 
documents and all other relevant data and conducted its own eight-
factor analysis in accordance with 21 U.S.C. 811(c). Included below is 
a brief summary of each factor as analyzed by HHS and DEA, and as 
considered by DEA in its proposed scheduling action. Please note that 
both DEA and HHS eight-factor analyses are available in their entirety 
under the tab ``Supporting Documents'' of the public docket of this 
rulemaking action at http://www.regulations.gov, under docket number 
``DEA-1142.''
    1. The Drug's Actual or Relative Potential for Abuse: The term 
``abuse'' is not defined in the CSA. However, the legislative history 
of the CSA suggests that DEA consider the following criteria when 
determining whether a particular drug or substance has a potential for 
abuse: \7\
---------------------------------------------------------------------------

    \7\ Comprehensive Drug Abuse Prevention and Control Act of 1970, 
H.R. Rep. No. 91-1444, 91st Cong., Sess. 1 (1970); reprinted in 1970 
U.S.C.C.A.N. 4566, 4603.
---------------------------------------------------------------------------

    (a) There is evidence that individuals are taking the drug or drugs 
containing such a substance in amounts sufficient to create a hazard to 
their health or to the safety of other individuals or to the community; 
or
    (b) There is significant diversion of the drug or drugs containing 
such a substance from legitimate drug channels; or
    (c) Individuals are taking the drug or drugs containing such a 
substance on their own initiative rather than on the basis of medical 
advice from a practitioner licensed by law to

[[Page 65333]]

administer such drugs in the course of his professional practice; or
    (d) The drug or drugs containing such a substance are new drugs so 
related in their action to a drug or drugs already listed as having a 
potential for abuse to make it likely that the drug will have the same 
potentiality for abuse as such drugs, thus making it reasonable to 
assume that there may be significant diversions from legitimate 
channels, significant use contrary to or without medical advice, or 
that it has a substantial capability of creating hazards to the health 
of the user or to the safety of the community.
    Both DEA and HHS eight-factor analyses found that ethylphenidate 
has abuse potential associated with its abilities to produce 
psychoactive effects that are similar to those produced by schedule II 
stimulants such as methylphenidate that have a high potential for 
abuse. In particular, the responses in humans to ethylphenidate are 
stimulant-like and include tachycardia, anxiety, hallucinations, 
impaired thinking, paranoia and hypertension.
    Ethylphenidate does not have an approved medical use in the United 
States. Thus, because this substance is not an approved drug product, a 
practitioner may not legally prescribe it, and it cannot be dispensed 
to an individual. DEA and HHS conclude that ethylphenidate is being 
abused for its psychoactive properties because it is being used without 
medical advice.
    Reports from the public health sector and law enforcement suggest 
that ethylphenidate is being abused and taken in amounts sufficient to 
create a hazard to an individual's health. This hazard is evidenced by 
deaths associated with ethylphenidate use which represents a safety 
issue for those in the community. Further, ethylphenidate was first 
reported to the National Forensic Laboratory Information System (NFLIS-
Drug) \8\ database in 2013; a January 2023 query of this database for 
ethylphenidate reports indicated a total of 191 such reports through 
2022 from 23 states by participating Federal, State, and local forensic 
laboratories. Consequently, the data indicate that ethylphenidate is 
being abused, and presents safety hazards to the health of individuals 
who consume it due to its stimulant properties, making it a hazard to 
the safety of the community.
---------------------------------------------------------------------------

    \8\ NFLIS 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 the nation's drug analysis cases. NFLIS-Drug 
participation rate, defined as the percentage of the national drug 
caseload represented by laboratories that have joined NFLIS-Drug, is 
currently 98.5 percent. 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, December 12, 2011. 
NFLIS data were queried on January 20, 2023.
---------------------------------------------------------------------------

    2. Scientific Evidence of the Drug's Pharmacological Effects, if 
Known: As described by HHS, studies show that ethylphenidate produces 
pharmacological effects that are similar to those produced by 
methylphenidate, a schedule II substance. Similar to these schedule II 
substances, ethylphenidate binds to monoamine transporters for dopamine 
and norepinephrine and blocks the uptake of these neurotransmitters at 
their transporters. Functionally, ethylphenidate, similar to 
methylphenidate and cocaine, inhibits norepinephrine and dopamine 
uptake. The potency of ethylphenidate in inhibiting norepinephrine 
uptake is about 6.75-fold less than that of methylphenidate and 1.7-
fold less than cocaine. With respect to behavioral data, according to 
HHS, while ethylphenidate is pharmacodynamically similar to 
methylphenidate, it is less potent than methylphenidate in the 
locomotor activity assay. Specifically, ethylphenidate is approximately 
80% as effective as methylphenidate in producing locomotor effect. 
Self-reports by users of ethylphenidate demonstrate that the drug 
produces typical stimulant-like effects, including euphoria and 
psychological and psychomotor stimulation. Overall, these data indicate 
that ethylphenidate produces stimulant-like pharmacological effects and 
behaviors that are similar to those of schedule II substances 
methylphenidate and methamphetamine.
    3. The State of Current Scientific Knowledge Regarding the Drug or 
Other Substance: Ethylphenidate is structurally similar to the schedule 
II substance methylphenidate. As stated in the HHS review, 
ethylphenidate is chemically known as ethyl 2-phenyl-2-piperidin-2-
ylacetate, (RS)-ethyl 2-phenyl-2-(piperidin-2-yl)acetate and dl-
ethylphenidate. Another name for ethylphenidate is EPH.
    Ethylphenidate user reports suggest that following insufflation, 
the pharmacokinetics of the drug are relatively rapid, with the onset 
of effects occurring approximately 13 minutes after administration 
(with a range of 0 to 35 minutes). Additionally, following oral 
ingestion, the mean onset of action is 23 minutes (ranging from 5 to 31 
minutes). According to published scientific literature, the mean 
duration of action of ethylphenidate is approximately 2 hours.
    As stated by HHS, there are no published clinical or nonclinical 
toxicology studies using ethylphenidate. Furthermore, the only evidence 
of the toxicological effects of ethylphenidate come from anecdotal user 
reports and fatal overdoses that implicated its role in a death.
    Neither DEA nor HHS is aware of any currently accepted medical use 
for ethylphenidate. According to HHS's August 2020 scientific and 
medical evaluation and scheduling recommendation, the Food and Drug 
Administration (FDA) has not approved a marketing application for a 
drug product containing ethylphenidate for any therapeutic indication, 
nor is HHS aware of any reports of clinical studies or claims of an 
accepted medical use for ethylphenidate in the United States.
    Although there is no evidence to suggest ethylphenidate 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, all of the 
following must be demonstrated: the drug's chemistry is known and 
reproducible; there are adequate safety studies; there are adequate and 
well-controlled studies proving efficacy; the drug is accepted by 
qualified experts; and the scientific evidence is 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 this 
analysis, ethylphenidate has no currently accepted medical use in the 
United States. Furthermore, DEA has not found any references regarding 
clinical testing of ethylphenidate in the scientific and medical 
literature. Taken together with HHS's conclusion, DEA finds that there 
is no legitimate medical use for ethylphenidate in the United States.
    4. History and Current Pattern of Abuse: As described by DEA and 
HHS, ethylphenidate is a stimulant and is structurally and 
pharmacologically similar to the schedule II substance, 
methylphenidate. Ethylphenidate has been trafficked and abused in North 
America and Europe since its first report of abuse in 2011. In 
addition, ethylphenidate has been identified in law enforcement 
seizures in the United States since 2013 and has persisted through 2020 
(There were no ethylphenidate-related NFLIS-Drug reports in 2021 and 
2022). Thus, ethylphenidate abuse occurs worldwide.

[[Page 65334]]

    5. Scope, Duration and Significance of Abuse: Forensic laboratories 
have confirmed the presence of ethylphenidate in drug exhibits received 
from State, local, and Federal law enforcement agencies. Law 
enforcement data show that ethylphenidate first appeared in the illicit 
drug market in 2013 with 10 encounters. Overall, from 2013 through 
2022, NFLIS registered 191 reports from Federal, State and local 
forensic laboratories identifying this substance in drug-related 
exhibits from 23 states. Thus, ethylphenidate abuse is wide-spread.
    6. What, if Any, Risk There Is to the Public Health: Based on the 
review of both HHS and DEA, public health risks of ethylphenidate 
result from its ability to induce stimulant-like responses, which may 
lead to adverse events that include psychological and cognitive 
impairment. Furthermore, risk to the public health is associated with 
adverse reactions in humans, which include hallucinations, impaired 
thinking, and paranoia. Nineteen deaths in the United Kingdom involving 
ethylphenidate have occurred between July 2013 and December 2014. A 
majority of these deaths involved males from East of Scotland with a 
history of current or previous heroin abuse. Additionally, according to 
the 2016 WHO Critical Review, these cases were almost exclusively 
associated with poly-drug use, with benzodiazepines, methadone, and 
other opioids being the most commonly detected drugs. Thus, the public 
health risks associated with ethylphenidate are confirmed by the 
pharmacological profile along with the fatalities associated with 
ethylphenidate use.
    7. Its Psychic or Physiological Dependence Liability: According to 
HHS, the psychic or physiological dependence liability of 
ethylphenidate can be inferred based on case reports and from data on 
substances that have similar pharmacological actions. As noted by HHS, 
scientific literature of published case reports demonstrate the 
propensity of ethylphenidate re-dosing by its users. Furthermore, 
according to self-reports users of ethylphenidate typically experience 
stimulant-like behavioral effects. In addition, DEA notes that because 
ethylphenidate shares pharmacological properties with schedule II 
stimulant substances such as methylphenidate and methamphetamine, 
ethylphenidate likely has a dependence profile similar to these 
substances, which are known to cause substance dependence.
    In summary, data suggests that ethylphenidate produces behavioral 
effects in animals and humans similar to those of schedule II 
stimulants. Although there are no clinical studies evaluating 
dependence liabilities specific for ethylphenidate, the pharmacological 
profile of this substance suggests that it possesses dependence 
liabilities qualitatively similar to schedule II substances such as 
methylphenidate and methamphetamine.
    8. Whether the Substance is an Immediate Precursor of a Substance 
Already Controlled Under the CSA: Ethylphenidate is not an immediate 
precursor of any controlled substance under the CSA as defined by 21 
U.S.C. 802(23).
    Conclusion: After considering the scientific and medical evaluation 
conducted by HHS, HHS's scheduling recommendation, and DEA's own eight-
factor analysis, DEA finds that the facts and all relevant data 
constitute substantial evidence of the potential for abuse of 
ethylphenidate. As such, DEA hereby proposes to permanently schedule 
ethylphenidate as a schedule I controlled substance under the CSA.

Proposed Determination of Appropriate Schedule

    The CSA establishes five schedules of controlled substances known 
as schedules I, II, III, IV, and V. The CSA also outlines the findings 
required to place a drug or other substance in any particular schedule. 
21 U.S.C. 812(b). After consideration of the analysis and 
recommendation of the Assistant Secretary for Health of HHS and review 
of all other available data, the Administrator of DEA, pursuant to 21 
U.S.C. 811(a) and 812(b)(1), finds that:
    1. Ethylphenidate has a high potential for abuse.
    Ethylphenidate, similar to the schedule II stimulants 
methylphenidate and methamphetamine, is a stimulant with a high 
potential for abuse. In animals, behavioral locomotor studies show that 
ethylphenidate produces stimulation similar to that of methylphenidate. 
Additionally, typical stimulant effects such as euphoria, psychomotor 
stimulation, and anxiety have been described from self-reports of 
ethylphenidate abusers. These effects are similar to those of schedule 
II stimulant such as methylphenidate and methamphetamine. These data 
collectively indicate that ethylphenidate has a high potential for 
abuse similar to other substances in schedule II such as 
methylphenidate and methamphetamine.
    2. Ethylphenidate currently has no accepted medical use in 
treatment in the United States.
    According to HHS, FDA has not approved a marketing application for 
a drug product containing ethylphenidate for any therapeutic 
indication. As HHS states, there are also no clinical studies or 
petitioners that claim an accepted medical use in the United States. In 
addition, as discussed above in the Factor 3 analysis, ethylphenidate 
does not satisfy DEA's five-part test for having a currently accepted 
medical use in treatment in the United States.
    3. There is a lack of accepted safety for use of ethylphenidate 
under medical supervision.
    Currently, ethylphenidate does not have an accepted medical use as 
noted by HHS. Because ethylphenidate has no approved medical use in 
treatment in the United States and has not been investigated as a new 
drug, its safety for use under medical supervision has not been 
determined. Thus, there is a lack of accepted safety for use of 
ethylphenidate under medical supervision.
    Although the first finding shows ethylphenidate to have similar 
effects to schedule II substances such as methylphenidate and 
methamphetamine, it bears reiterating that there is only one possible 
schedule in the CSA--schedule I--to place ethylphenidate since it has 
no currently accepted medical use in treatment in the United States. 
See the background section for additional discussion.
    Based on these findings, the Administrator concludes that 
ethylphenidate (chemical name: ethyl 2-phenyl-2-(piperidin-2-
yl)acetate), including its salts, isomers, and salts of isomers, 
warrants control in schedule I of the CSA. 21 U.S.C. 812(b)(1). More 
precisely, because of its stimulant-like effects, DEA is proposing to 
place ethylphenidate in 21 CFR 1308.11(f) (the stimulants category of 
schedule I). As such, the proposed control of ethylphenidate also 
includes its salts, isomers, and salts of isomers.

Requirements for Handling Ethylphenidate

    If this rule is finalized as proposed, ethylphenidate would be 
subject to the CSA's schedule I regulatory controls and administrative, 
civil, and criminal sanctions applicable to the manufacture, 
distribution, reverse distribution, importation, exportation, 
engagement in research, and conduct of instructional activities or 
chemical analysis with, and possession of schedule I controlled 
substances including the following:
    1. Registration. Any person who handles (manufactures, distributes, 
reverse distributes, imports, exports, engages in research, or conducts

[[Page 65335]]

instructional activities or chemical analysis with, or possesses) 
ethylphenidate, or who desires to handle ethylphenidate, is required to 
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 the effective date of a final scheduling action. Any person 
who currently handles ethylphenidate, and is not registered with DEA, 
would need to submit an application for registration and may not 
continue to handle ethylphenidate as of the effective date of a final 
scheduling action, unless DEA has approved that application for 
registration pursuant to 21 U.S.C. 822, 823, 957, 958, and in 
accordance with 21 CFR parts 1301 and 1312.
    2. Disposal of stocks. Any person who does not desire or is not 
able to obtain a schedule I registration would be required to surrender 
all quantities of currently held ethylphenidate or to transfer all 
quantities of currently held ethylphenidate to a person registered with 
DEA before the effective date of a final scheduling action, in 
accordance with all applicable Federal, State, local, and Tribal laws. 
As of the effective date of a final scheduling action, ethylphenidate 
would be required to be disposed of in accordance with 21 CFR part 
1317, in addition to all other applicable Federal, State, local, and 
Tribal laws.
    3. Security. Ethylphenidate would be subject to schedule I security 
requirements and would need to be handled and stored pursuant to 21 
U.S.C. 821, 823, 871(b) and in accordance with 21 CFR 1301.71-1301.93 
as of the effective date of a final scheduling action. Non-
practitioners handling ethylphenidate would also need to comply with 
the employee screening requirements of 21 CFR 1301.90 -1301.93.
    4. Labeling and Packaging. All labels, labeling, and packaging for 
commercial containers of ethylphenidate would need to be in compliance 
with 21 U.S.C. 825 and 958(e) and be in accordance with 21 CFR part 
1302 as of the effective date of a final scheduling action.
    5. Quota. Only registered manufacturers would be permitted to 
manufacture ethylphenidate in accordance with a quota assigned pursuant 
to 21 U.S.C. 826 and in accordance with 21 CFR part 1303 as of the 
effective date of a final scheduling action.
    6. Inventory. Every DEA registrant who possesses any quantity of 
ethylphenidate on the effective date of a final scheduling action would 
be required to take an inventory of ethylphenidate on hand at that 
time, pursuant to 21 U.S.C. 827 and 958 and in accordance with 21 CFR 
1304.03, 1304.04, and 1304.11(a) and (d).
    Any person who becomes registered with DEA to handle ethylphenidate 
on or after the effective date of a final scheduling action would be 
required to have an initial inventory of all stocks of controlled 
substances (including ethylphenidate) on hand on the date the 
registrant first engages in the handling of controlled substances 
pursuant to 21 U.S.C. 827 and 958, and in accordance with 21 CFR 
1304.03, 1304.04, and 1304.11(a) and (b).
    After the initial inventory, every DEA registrant must take an 
inventory of all controlled substances (including ethylphenidate) on 
hand every two years, pursuant to 21 U.S.C. 827 and 958, and in 
accordance with 21 CFR 1304.03, 1304.04, and 1304.11.
    7. Records and Reports. Every DEA registrant would be required to 
maintain records and submit reports with respect to ethylphenidate 
pursuant to 21 U.S.C. 827 and 958(e) and in accordance with 21 CFR 
parts 1304 and 1312, as of the effective date of a final scheduling 
action. Manufacturers and distributors would be required to submit 
reports regarding ethylphenidate to the Automation of Reports and 
Consolidated Order System pursuant to 21 U.S.C. 827 and in accordance 
with 21 CFR parts 1304 and 1312, as of the effective date of a final 
scheduling action.
    8. Order Forms. Every DEA registrant who distributes ethylphenidate 
would be required to comply with the order form requirements, pursuant 
to 21 U.S.C. 828 and in accordance with 21 CFR part 1305, as of the 
effective date of a final scheduling action.
    9. Importation and Exportation. All importation and exportation of 
ethylphenidate would need to be in compliance with 21 U.S.C. 952, 953, 
957, and 958, and in accordance with 21 CFR part 1312, as of the 
effective date of a final scheduling action.
    10. Liability. Any activity involving ethylphenidate not authorized 
by, or in violation of, the CSA or its implementing regulations would 
be unlawful, and may subject the person to administrative, civil, and/
or criminal sanctions.

Regulatory Analyses

Executive Orders 12866 (Regulatory Planning and Review) and 13563 
(Improving Regulation and Regulatory Review)

    In accordance with 21 U.S.C. 811(a), this proposed scheduling 
action is subject to formal rulemaking procedures performed ``on the 
record after opportunity for a hearing,'' which are conducted pursuant 
to the provisions of 5 U.S.C. 556 and 557. The CSA sets forth the 
criteria for scheduling a drug or other substance. Such actions are 
exempt from review by the Office of Management and Budget (OMB) 
pursuant to section 3(d)(1) of Executive Order (E.O.) 12866 and the 
principles reaffirmed in E.O. 13563.

Executive Order 12988, Civil Justice Reform

    This proposed regulation meets the applicable standards set forth 
in sections 3(a) and 3(b)(2) of E.O. 12988 to eliminate drafting errors 
and ambiguity, minimize litigation, provide a clear legal standard for 
affected conduct, and promote simplification and burden reduction.

Executive Order 13132, Federalism

    This proposed rulemaking does not have federalism implications 
warranting the application of E.O. 13132. The proposed rule does not 
have substantial direct effects on the States, on the relationship 
between the national government and the States, or the distribution of 
power and responsibilities among the various levels of government.

Executive Order 13175, Consultation and Coordination With Indian Tribal 
Governments

    This proposed rule does not have tribal implications warranting the 
application of E.O. 13175. It does not have substantial direct effects 
on one or more Indian tribes, on the relationship between the Federal 
government and Indian tribes, or on the distribution of power and 
responsibilities between the Federal government and Indian tribes.

Regulatory Flexibility Act

    The Administrator, in accordance with the Regulatory Flexibility 
Act, 5 U.S.C. 601-602, has reviewed this proposed rule and by approving 
it certifies that it will not have a significant economic impact on a 
substantial number of small entities.
    DEA proposes placing the substance ethylphenidate (chemical name: 
ethyl 2-phenyl-2-(piperidin-2-yl)acetate), including its salts, 
isomers, and salts of isomers, in schedule I of the CSA. This action is 
being taken to enable the United States to meet its obligations under 
the 1971 Convention on Psychotropic Substances. If finalized, this 
action would impose the regulatory controls and administrative, civil, 
and criminal sanctions applicable to

[[Page 65336]]

schedule I controlled substances on persons who handle (manufacture, 
distribute, reverse distribute, import, export, engage in research, 
conduct instructional activities or chemical analysis with, or 
possess), or propose to handle, ethylphenidate.
    According to HHS, ethylphenidate has a high potential for abuse, 
has no currently accepted medical use in treatment in the United 
States, and lacks accepted safety for use under medical supervision. 
DEA's research confirms that there is no legitimate commercial market 
for ethylphenidate in the United States. Therefore, DEA estimates that 
no United States entity currently handles ethylphenidate and does not 
expect any United States entity to handle ethylphenidate in the 
foreseeable future. DEA concludes that no legitimate United States 
entity would be affected by this rule if finalized. As such, the 
proposed rule will not have a significant effect on a substantial 
number of small entities.

Unfunded Mandates Reform Act of 1995

    In accordance with the Unfunded Mandates Reform Act (UMRA) of 1995, 
2 U.S.C. 1501 et seq., DEA has determined and certifies that this 
action would not result in any Federal mandate that may result ``in the 
expenditure by State, local, and tribal governments, in the aggregate, 
or by the private sector, of $100 million or more (adjusted annually 
for inflation) in any 1 year * * *.'' Therefore, neither a Small 
Government Agency Plan nor any other action is required under UMRA of 
1995.

Paperwork Reduction Act of 1995

    This action does not impose a new collection of information under 
the Paperwork Reduction Act of 1995. 44 U.S.C. 3501-3521.
