                hearing as set forth in 21 CFR 1308.44(c).
                 All requests for a hearing and waivers of participation, together
                with a written statement of position on the matters of fact and law
                involved in such hearing, must be sent to DEA using the address
                information provided above.
                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 on his own motion. 21 U.S.C. 811(a).
                This proposed action is supported by a recommendation from the
                Assistant Secretary for Health of the Department of Health and Human
                Services (HHS) and an evaluation of all other relevant data by DEA. If
                finalized, this action would make permanent the existing temporary
                regulatory controls and administrative, civil, and criminal sanctions
                for schedule I controlled substances on any person who handles
                (manufactures, distributes, imports, exports, engages in research,
                conducts instructional activities or chemical analysis, or possesses)
                or proposes to handle N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8,
                or 4-chloro-[alpha]-PVP.
                Background
                 On July 18, 2019, pursuant to 21 U.S.C. 811(h)(1), DEA published an
                order in the Federal Register (84 FR 34291) temporarily placing N-
                ethylhexedrone, alpha-pyrrolidinohexanophenone ([alpha]-PHP), 4-methyl-
                alpha-ethylaminopentiophenone (4-MEAP), 4'-methyl-alpha-
                pyrrolidinohexiophenone (MPHP), alpha-pyrrolidinoheptaphenone (PV8),
                and 4'-chloro-alpha-pyrrolidinovalerophenone (4-chloro-[alpha]-PVP) in
                schedule I of the CSA upon finding that these synthetic cathinones pose
                an imminent hazard to the public safety. That temporary order was
                effective on the date of publication. Pursuant to 21 U.S.C. 811(h)(2),
                the temporary control of these substances is set to expire on July 18,
                2021. However, this same subsection also provides that, during the
                pendency of proceedings under 21 U.S.C. 811(a)(1) with respect to a
                substance, the temporary scheduling of that substance may be extended
                for up to one year. Proceedings for the scheduling of a substance under
                21 U.S.C. 811(a) may be initiated by the Attorney General (delegated to
                the Administrator of DEA (Administrator) pursuant to 28 CFR 0.100) on
                his own motion, at the request of the Secretary of HHS,\1\ or on the
                petition of any interested party. An extension of the existing
                temporary order is being ordered by the Administrator in a separate
                action, and is being simultaneously published elsewhere in this issue
                of the Federal Register.
                ---------------------------------------------------------------------------
                 \1\ Because the Secretary of HHS has delegated to the Assistant
                Secretary for Health (Assistant Secretary) the authority to make
                domestic drug scheduling recommendations, for purposes of this
                proposed rulemaking, all subsequent references to ``Secretary'' have
                been replaced with ``Assistant Secretary.''
                ---------------------------------------------------------------------------
                 The Administrator, on her own motion, is initiating proceedings
                under 21 U.S.C. 811(a)(1) to permanently schedule N-ethylhexedrone,
                [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP. DEA has
                gathered and reviewed the available information regarding the
                pharmacology, chemistry, trafficking, actual abuse, pattern of abuse,
                and the relative potential for abuse for these synthetic cathinones. On
                October 22, 2020, the Acting Administrator of DEA submitted a request
                to the Assistant Secretary for Health of HHS (Assistant Secretary) to
                provide DEA with a scientific and medical evaluation of available
                information and a scheduling recommendation for N-ethylhexedrone,
                [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP, in accordance
                with 21 U.S.C. 811(b) and (c). Upon evaluating the scientific and
                medical evidence, on July 8, 2021, the Assistant Secretary submitted to
                the Acting Administrator HHS's scientific and medical evaluation and
                scheduling recommendation for these substances. Upon receipt of the
                scientific and medical evaluation and scheduling recommendation from
                HHS, DEA reviewed the document and all other relevant data, and
                conducted its own eight-factor analysis of the abuse potential of N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP in accordance with 21 U.S.C. 811(c).
                Proposed Determination of Schedule N-Ethylhexedrone, [alpha]-PHP, 4-
                MEAP, MPHP, PV8, and 4-Chloro-[alpha]-PVP
                 As discussed in the background section, the Administrator is
                initiating proceedings, pursuant to 21 U.S.C. 811(a)(1), to add N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP permanently to schedule I. DEA has reviewed the scientific and
                medical evaluation and scheduling recommendation, received from HHS,
                and all other relevant data and conducted its own eight-factor analysis
                of the abuse potential of N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP,
                PV8, and 4-chloro-[alpha]-PVP pursuant to 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 the DEA and the HHS 8-Factor analyses and the Assistant
                Secretary's July 8, 2021 letter 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-495.''
                 1. The Drug's Actual or Relative Potential for Abuse: Both the DEA
                and the HHS 8-factor analyses found that N-ethylhexedrone, [alpha]-PHP,
                4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP have abuse potential
                associated with its abilities to produce psychoactive effects that are
                similar to those produced by schedule I synthetic cathinones such as
                methcathinone, mephedrone, methylone, pentylone, and 3,4-
                methylenedioxypyrovalerone (MDPV) and schedule II stimulants such as
                methamphetamine and cocaine that have a high potential for abuse. In
                particular, the responses in humans to N-ethylhexedrone, [alpha]-PHP,
                4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP are stimulant-like and
                include paranoia, agitation, palpitations, tachycardia, hypertension,
                and hyperthermia.
                 N-Ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-
                [alpha]-PVP have no approved medical uses in the United
                [[Page 37721]]
                States but there have been reports of individuals experiencing adverse
                outcomes after taking these substances. Because these substances are
                not approved drug products, a practitioner may not legally prescribe
                them, and they cannot be dispensed to an individual. The use of these
                substances without medical advice leads to the conclusion that these
                synthetic cathinones are being abused for their psychoactive
                properties.
                 Reports from public health and law enforcement state that these
                substances are being abused and taken in amounts sufficient to create a
                hazard to an individual's health. This hazard is evidenced by emergency
                department admissions or deaths, representing a significant safety
                issue for those in the community. Further, from January 2012 through
                December 2020 (query date: May 3, 2021), the National Forensic
                Laboratory Information System (NFLIS) databases registered a total of
                2,289 reports by participating DEA, State, local, and other forensic
                laboratories, as applicable, pertaining to N-ethylhexedrone, [alpha]-
                PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP.\2\ NFLIS registered
                these reports identifying these substances in drug-related exhibits
                from more than 40 States. MPHP was first identified in June 2012 in
                seized drug evidence (although MPHP was identified in blood samples
                from a 27-year-old decedent in 2011), followed by 4-MEAP and PV8
                (August and December 2013, respectively), alpha-PHP (May 2014), 4-
                chloro-[alpha]-PVP (December 2015) and most recently N-ethylhexedrone
                (August 2016). Consequently, the data indicate that N-ethylhexedrone,
                [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP are being
                abused, and they present safety hazards to the health of individuals
                who consume them due to their stimulant properties.

                 \2\ NFLIS is a national drug forensic laboratory reporting
                system that systematically collects results from drug chemistry
                analyses conducted by state and local forensic laboratories across
                the country. The NFLIS participation rate, defined as the percentage
                of the national drug caseload represented by laboratories that have
                joined NFLIS, is over 97 percent. NFLIS includes drug chemistry
                results from completed analyses only.

                 2. Scientific Evidence of the Drug's Pharmacological Effects, if
                Known: As described by HHS, studies show that N-ethylhexedrone,
                [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP produce
                pharmacological effects that are similar to those produced by schedule
                I and II substances such as methamphetamine (II), cocaine (II),
                mephedrone (I), MDPV (I), and methylone (I). Similar to these schedule
                I and II substances, N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8,
                and 4-chloro-[alpha]-PVP bind to monoamine transporters for dopamine
                and norepinephrine, and block the uptake of these neurotransmitters at
                their transporters. N-Ethylhexedrone, [alpha]-PHP, and MPHP (4-MEAP,
                PV8, and 4-chloro-[alpha]-PVP were not tested in this assay) do not
                promote the release of these monoamines. Additionally, behavioral
                studies in animals demonstrate that N-ethylhexedrone, [alpha]-PHP, 4-
                MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP produce locomotor behavior
                and discriminative stimulus effects that are similar to those of
                methamphetamine and cocaine. Overall, these data indicate that N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP produce pharmacological effects and stimulant-like behaviors that
                are similar to those of other schedule I synthetic cathinones such as
                methcathinone, mephedrone, MDPV, and methylone, as well as schedule II
                stimulants methamphetamine and cocaine.
                 3. The State of Current Scientific Knowledge Regarding the Drug or
                Other Substance: N-Ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and
                4-chloro-[alpha]-PVP are designer drugs of the phenethylamine class and
                they are structurally similar to permanently controlled schedule I
                synthetic cathinones and schedule II stimulants like methamphetamine.
                 Pharmacokinetic studies show that humans, in general, metabolize
                synthetic cathinones to their corresponding amphetamines followed by
                reduction of the beta-keto group to the corresponding alcohol which can
                involve hydrogenation, deethylation, demethylation, or hydroxylation.
                Given that N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-
                chloro-[alpha]-PVP are synthetic cathinones, it is likely that these
                six synthetic cathinones are also metabolized to their corresponding
                amphetamines and alcohols.
                 Neither DEA nor HHS is aware of any currently accepted medical use
                for N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-
                [alpha]-PVP. According to HHS's 2021 scientific and medical evaluation
                and scheduling recommendation, the Food and Drug Administration (FDA)
                has not approved marketing applications for drug products containing N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP for any therapeutic indication, nor is HHS aware of any reports of
                clinical studies or claims of accepted medical use for N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP in the United States.
                 A drug has a ``currently accepted medical use'' if 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.\3\ Based on this analysis, N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP have no currently accepted medical use in the United States.
                Furthermore, DEA has not found any references regarding clinical
                testing of these substances in the scientific and medical literature.
                Although the chemistry of synthetic cathinones, in general, is known
                and has been reproduced, as mentioned above there are no clinical
                studies involving N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and
                4-chloro-[alpha]-PVP. Taken together with HHS's conclusion, DEA finds
                that there is no legitimate medical use for N-ethylhexedrone, [alpha]-
                PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP in the United States.

                 4. History and Current Pattern of Abuse: Available evidence
                suggests that the history and pattern of abuse of N-ethylhexedrone,
                [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP parallel that
                of permanently controlled schedule I cathinone stimulants. N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP are synthetic cathinones of the phenethylamine class and they are
                structurally and pharmacologically similar to schedule I and II
                substances such as methcathinone (I) and methamphetamine (II). Like
                these schedule I and II substances, N-ethylhexedrone, [alpha]-PHP, 4-
                MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP are most likely ingested by
                swallowing capsules or tablets or snorted by nasal insufflation of the
                powder tablets. As reported by DEA and HHS, products containing N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, or 4-chloro-[alpha]-
                PVP, similar to schedule I synthetic cathinones, are likely to be
                falsely marketed as ``research chemicals,'' ``jewelry cleaner,''
                ``stain remover,'' ``plant food or fertilizer,'' ``insect repellants,''
                or ``bath salts;'' sold at smoke shops, head shops, convenience stores,
                adult book stores, or gas stations; and purchased on the internet. Like
                those seen with commercial products
                [[Page 37722]]
                that contain synthetic cathinones, the packages of products that
                contain N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, or 4-chloro-
                [alpha]-PVP also probably contain the warning ``not for human
                consumption,'' most likely in an effort to circumvent statutory
                restrictions for these substances. Law enforcement data indicate that
                N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP are available for illicit use and are being abused. Demographic
                data collected from published reports and mortality records suggest
                that the main users of N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP,
                PV8, and 4-chloro-[alpha]-PVP, similar to other schedule I synthetic
                cathinones permanently placed in schedule I, are young adults.
                Toxicology reports also revealed that N-ethylhexedrone, [alpha]-PHP, 4-
                MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP are being ingested with other
                substances including other synthetic cathinones, common cutting agents,
                or other recreational substances. Consequently, products containing
                synthetic cathinones, including N-ethylhexedrone, [alpha]-PHP, 4-MEAP,
                MPHP, PV8, or 4-chloro-[alpha]-PVP, are distributed to users, often
                with unpredictable outcomes. Thus, the recreational abuse of N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP is a significant concern. These data indicate that N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP have a history and current pattern of abuse.
                 5. Scope, Duration and Significance of Abuse: N-ethylhexedrone,
                [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP are
                recreational drugs that emerged on the United States' illicit drug
                market after the scheduling of other synthetic cathinones (e.g., N-
                ethylpentylone, ethylone, mephedrone, methylone, pentylone, and MDPV)
                (see DEA's Eight Factor Analysis for a full discussion). Forensic
                laboratories have confirmed the presence of N-ethylhexedrone, [alpha]-
                PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP in drug exhibits
                received from Federal, State, and local law enforcement agencies. MPHP
                was first identified in June 2012 in seized drug evidence (although
                MPHP was identified in blood samples from a 27-year-old decedent in
                2011--see Factor 6 for details), followed by 4-MEAP and PV8 (August and
                December 2013, respectively), alpha-PHP (May 2014), 4-chloro-[alpha]-
                PVP (December 2015) and most recently N-ethylhexedrone (August 2016).
                From January 2012 through December 2020 (query date: May 3, 2021),
                NFLIS database registered a total of 2,289 reports from forensic
                laboratories pertaining to the 6 synthetic cathinones (N-
                ethylhexedrone, 613 reports; [alpha]-PHP--984 reports; 4-MEAP--131
                reports; MPHP--92 reports; PV8--174 reports; and 4-chloro-[alpha]-PVP--
                295 reports). HHS reported that there were 13,238 calls to United
                States poison control centers (PCCs) \4\ involving synthetic cathinones
                from 2010 to 2019 and 39 mentions of cathinones of which 23 were for
                [alpha]-PHP on the Dashboard \5\ from July 2018 to July 2020.
                Accordingly, concerns over the continuing abuse of synthetic cathinones
                have led to the control of many synthetic cathinones. A full
                presentation of the NFLIS reports by substance and year, PCC, and
                Dashboard data are available in both DEA's and HHS's eight-factor
                analyses within the Supporting Documents section of the public docket
                available at http://www.regulations.gov.
                ---------------------------------------------------------------------------
                 \4\ PCC data are derived from the National Poison Data System, a
                database managed by the American Association of Poison Control
                Centers (AAPCC). AAPCC is a nationwide network of PCCs that receive
                calls from individuals, healthcare professionals, and other
                interested persons in the general U.S. population regarding
                exposures to prescription drugs and other substances.
                 \5\ The Dashboard is an online, interactive tool that reports on
                the identification of certain novel psychoactive substances in de-
                identified sample extracts from forensic investigations, including
                medicolegal death investigations and toxicology testing. The
                Dashboard was accessed on February 26, 2021.

                 6. What, if Any, Risk There Is to the Public Health: HHS reported
                that the public health risks of N-ethylhexedrone, [alpha]-PHP, 4-MEAP,
                MPHP, PV8, and 4-chloro-[alpha]-PVP result from their ability to induce
                stimulant-like responses, which may lead to impaired judgement and
                dangerous behavior. Adverse health effects associated with the abuse of
                N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP include a number of stimulant-like adverse health effects such as
                diaphoresis, insomnia, mydriasis, hyperthermia, vomiting, agitation,
                disorientation, paranoia, and abdominal pain. Serious adverse events
                such as acute kidney failure, cardiac arrest, rhabdomyolysis, and coma
                have been associated with the use of N-ethylhexedrone, [alpha]-PHP, 4-
                MEAP, and PV8. In addition, N-ethylhexedrone, [alpha]-PHP, MPHP, and
                PV8 have been involved in the deaths of individuals. The identification
                of N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, or 4-chloro-
                [alpha]-PVP in toxicological samples associated with fatal and non-
                fatal overdoses as reported in the medical and scientific literature,
                forensic laboratory reports, and public health documents confirms these
                adverse effects of N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, or
                4-chloro-[alpha]-PVP. Like schedule I synthetic cathinones, N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP have caused acute health problems leading to emergency department
                (ED) admissions, violent behaviors causing harm to self or others, and/
                or death. Specifically, evidence demonstrate that all six synthetic
                cathinones have resulted in ED visits that required medical attention,
                but only N-ethylhexedrone, [alpha]-PHP, MPHP, and PV8 abuse have been
                associated with the deaths of individuals. It remains highly likely
                that additional cases of adverse health effects involving N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP in the United States have occurred and will continue to be under-
                reported as these substances are not part of standard panels for
                toxicological analyses of biological specimens. Thus, the abuse of N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP, like that of the abuse of schedule I synthetic cathinones and
                stimulant drugs, poses significant adverse health risks including
                death.
                 Furthermore, because abusers of synthetic cathinones obtain these
                substances through unregulated sources, the identity, purity, and
                quantity are uncertain and inconsistent. These unknown factors pose an
                additional risk for significant adverse health effects to the end user.
                 Based on information received by DEA, the abuse of N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP has led to, at least, the same qualitative public health risks as
                other schedule I synthetic cathinones and the schedule II stimulant
                methamphetamine. The public health risks attendant to the abuse of
                synthetic cathinones, including N-ethylhexedrone, [alpha]-PHP, 4-MEAP,
                MPHP, PV8, or 4-chloro-[alpha]-PVP, are well established and have
                resulted in large numbers of ED visits and fatal overdoses.
                 7. Its Psychic or Physiological Dependence Liability: According to
                HHS, the psychic or physiological dependence liability of N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP is demonstrated by their positive abuse-related studies in animals
                and reported stimulant effects in humans. The results from two
                behavioral studies (drug discrimination and locomotor studies)
                demonstrate that N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, or
                4-chloro-[alpha]-PVP produced behavioral effects that are similar to
                those of substances with
                [[Page 37723]]
                stimulant effects such as the schedule II stimulants cocaine and
                methamphetamine. Thus, based on the structural and pharmacological
                similarities of N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and
                4-chloro-[alpha]-PVP to schedule II stimulant substances that have
                demonstrated psychic or physiological dependence liability, it is
                anticipated that the stimulant properties of N-ethylhexedrone, [alpha]-
                PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP produce psychic
                dependence liability.
                 8. Whether the Substance is an Immediate Precursor of a Substance
                Already Controlled Under the CSA: N-Ethylhexedrone, [alpha]-PHP, 4-
                MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP are not immediate precursors
                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 N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP. As such, DEA hereby proposes to permanently schedule N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP as controlled substances under the CSA.
                Proposed Determination of Appropriate SSchedule
                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. N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-
                [alpha]-PVP have a high potential for abuse;
                 2. N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-
                [alpha]-PVP have no currently accepted medical use in treatment in the
                United States; and
                 3. There is a lack of accepted safety for use of N-ethylhexedrone,
                [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-PVP under medical
                supervision.
                 Based on these findings, the Administrator concludes that N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP, including their salts, isomers, and salts of isomers, whenever the
                existence of such salts, isomers, and salts of isomers is possible
                within the specific chemical designation, warrant control in schedule I
                of the CSA. 21 U.S.C. 812(b)(1).
                Requirements for Handling N-Ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP,
                PV8, and 4-Chloro-[alpha]-PVP
                 If this rule is finalized as proposed, N-ethylhexedrone, [alpha]-
                PHP, 4-MEAP, MPHP, PV8, or 4-chloro-[alpha]-PVP would continue \6\ to
                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, research, and conduct of instructional activities
                involving the handling of schedule I controlled substances including
                the following:

                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
                [[Page 37724]]
                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. 601-612, 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. On July 18, 2019, DEA published
                an order to temporarily place N-ethylhexedrone, [alpha]-PHP, 4-MEAP,
                MPHP, PV8, and 4-chloro-[alpha]-PVP in schedule I of the CSA pursuant
                to the temporary scheduling provisions of 21 U.S.C. 811(h). DEA
                estimates that all entities handling or planning to handle these
                substances have already established and implemented the systems and
                processes required to handle N-ethylhexedrone, [alpha]-PHP, 4-MEAP,
                MPHP, PV8, or 4-chloro-[alpha]-PVP. There are currently 34 unique
                registrations authorized to handle N-ethylhexedrone, [alpha]-PHP, 4-
                MEAP, MPHP, PV8, or 4-chloro-[alpha]-PVP specifically, as well as a
                number of registered analytical labs that are authorized to handle
                schedule I controlled substances generally. From review of entity
                names, DEA estimates these 34 registrations represent 29 entities. Some
                of these entities are likely to be large entities. However, since DEA
                does not have information of registrant size and the majority of DEA
                registrants are small entities or are employed by small entities, DEA
                estimates a maximum of 29 entities are small entities. Therefore, DEA
                conservatively estimates as many as 29 small entities are affected by
                this proposed rule.
                 A review of the 34 registrations indicates that all entities that
                currently handle N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, or
                4-chloro-[alpha]-PVP also handle other schedule I controlled
                substances, and thus they have established and implemented (or
                maintain) the systems and processes required to handle N-
                ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-[alpha]-
                PVP as a schedule I substance. Therefore, DEA anticipates that this
                proposed rule will impose minimal or no economic impact on any affected
                entities, and, thus, will not have a significant economic impact on any
                of the 29 affected small entities. Therefore, DEA has concluded that
                this proposed rule will not have a significant economic impact 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
                proposed 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 $100,000,000 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 proposed action does not impose a new collection of
                information under the Paperwork Reduction Act of 1995. 44 U.S.C. 3501-
                3521. This proposed action would not impose recordkeeping or reporting
                requirements on State or local governments, individuals, businesses, or
                organizations. An agency may not conduct or sponsor, and a person is
                not required to respond to, a collection of information unless it
                displays a currently valid OMB control number.

                Reporting and recordkeeping requirements.
                 For the reasons set out above, DEA proposes to amend 21 CFR part
                1308 as follows:
