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, a-PHP, 4MEAP, MPHP, PV8, or 4-chloro-a-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 Nethylhexedrone, alphapyrrolidinohexanophenone (a-PHP), 4methyl-alphaethylaminopentiophenone (4-MEAP), 4′methyl-alpha-pyrrolidinohexiophenone
(MPHP), alphapyrrolidinoheptaphenone (PV8), and 4′chloro-alpha-pyrrolidinovalerophenone
(4-chloro-a-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.
The Administrator, on her own
motion, is initiating proceedings under
21 U.S.C. 811(a)(1) to permanently
schedule N-ethylhexedrone, a-PHP, 4MEAP, MPHP, PV8, and 4-chloro-aPVP. 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,
a-PHP, 4-MEAP, MPHP, PV8, and 4chloro-a-PVP, in accordance with 21
U.S.C. 811(b) and (c). Upon evaluating
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

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, a-PHP,
4-MEAP, MPHP, PV8, and 4-chloro-aPVP in accordance with 21 U.S.C.
811(c).
Proposed Determination of Schedule
N-Ethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-Chloro-a-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, aPHP, 4-MEAP, MPHP, PV8, and 4chloro-a-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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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 https://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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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 3,4methylenedioxypyrovalerone (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, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP are
stimulant-like and include paranoia,
agitation, palpitations, tachycardia,
hypertension, and hyperthermia.
N-Ethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP have
no approved medical uses in the United

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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP.2
NFLIS registered these reports
identifying these substances in drugrelated 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), 4chloro-a-PVP (December 2015) and most
recently N-ethylhexedrone (August
2016). Consequently, the data indicate
that N-ethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP are
being abused, and they present safety
hazards to the health of individuals who
consume them due to their stimulant
properties.
2. Scientific Evidence of the Drug’s
Pharmacological Effects, if Known: As
described by HHS, studies show that Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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
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.

I and II substances, N-ethylhexedrone,
a-PHP, 4-MEAP, MPHP, PV8, and 4chloro-a-PVP bind to monoamine
transporters for dopamine and
norepinephrine, and block the uptake of
these neurotransmitters at their
transporters. N-Ethylhexedrone, a-PHP,
and MPHP (4-MEAP, PV8, and 4-chloroa-PVP were not tested in this assay) do
not promote the release of these
monoamines. Additionally, behavioral
studies in animals demonstrate that Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP
produce locomotor behavior and
discriminative stimulus effects that are
similar to those of methamphetamine
and cocaine. Overall, these data indicate
that N-ethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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, a-PHP, 4MEAP, MPHP, PV8, and 4-chloro-a-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, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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,
a-PHP, 4-MEAP, MPHP, PV8, and 4chloro-a-PVP for any therapeutic
indication, nor is HHS aware of any
reports of clinical studies or claims of
accepted medical use for Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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, a-PHP,
4-MEAP, MPHP, PV8, and 4-chloro-aPVP 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, aPHP, 4-MEAP, MPHP, PV8, and 4chloro-a-PVP. Taken together with
HHS’s conclusion, DEA finds that there
is no legitimate medical use for Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP in the
United States.
4. History and Current Pattern of
Abuse: Available evidence suggests that
the history and pattern of abuse of Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP
parallel that of permanently controlled
schedule I cathinone stimulants. Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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, Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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, a-PHP, 4MEAP, MPHP, PV8, or 4-chloro-a-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

that contain synthetic cathinones, the
packages of products that contain Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, or 4-chloro-a-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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP,
similar to other schedule I synthetic
cathinones permanently placed in
schedule I, are young adults. Toxicology
reports also revealed that Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP are
being ingested with other substances
including other synthetic cathinones,
common cutting agents, or other
recreational substances. Consequently,
products containing synthetic
cathinones, including Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, or 4-chloro-a-PVP, are
distributed to users, often with
unpredictable outcomes. Thus, the
recreational abuse of N-ethylhexedrone,
a-PHP, 4-MEAP, MPHP, PV8, and 4chloro-a-PVP is a significant concern.
These data indicate that Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP have a
history and current pattern of abuse.
5. Scope, Duration and Significance
of Abuse: N-ethylhexedrone, a-PHP, 4MEAP, MPHP, PV8, and 4-chloro-a-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, aPHP, 4-MEAP, MPHP, PV8, and 4chloro-a-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 27year-old decedent in 2011—see Factor 6
for details), followed by 4-MEAP and
PV8 (August and December 2013,
respectively), alpha-PHP (May 2014), 4chloro-a-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
VerDate Sep<11>2014
16:52 Jul 15, 2021
Jkt 253001
of 2,289 reports from forensic
laboratories pertaining to the 6 synthetic
cathinones (N-ethylhexedrone, 613
reports; a-PHP—984 reports; 4-MEAP—
131 reports; MPHP—92 reports; PV8—
174 reports; and 4-chloro-a-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 a-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 https://
www.regulations.gov.
6. What, if Any, Risk There Is to the
Public Health: HHS reported that the
public health risks of N-ethylhexedrone,
a-PHP, 4-MEAP, MPHP, PV8, and 4chloro-a-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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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 Nethylhexedrone, a-PHP, 4-MEAP, and
PV8. In addition, N-ethylhexedrone, aPHP, MPHP, and PV8 have been
involved in the deaths of individuals.
The identification of N-ethylhexedrone,
a-PHP, 4-MEAP, MPHP, PV8, or 4chloro-a-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
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.

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

documents confirms these adverse
effects of N-ethylhexedrone, a-PHP, 4MEAP, MPHP, PV8, or 4-chloro-a-PVP.
Like schedule I synthetic cathinones, Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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, aPHP, 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, aPHP, 4-MEAP, MPHP, PV8, and 4chloro-a-PVP in the United States have
occurred and will continue to be underreported as these substances are not part
of standard panels for toxicological
analyses of biological specimens. Thus,
the abuse of N-ethylhexedrone, a-PHP,
4-MEAP, MPHP, PV8, and 4-chloro-aPVP, 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, aPHP, 4-MEAP, MPHP, PV8, and 4chloro-a-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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, or 4-chloro-a-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 Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP is
demonstrated by their positive abuserelated studies in animals and reported
stimulant effects in humans. The results
from two behavioral studies (drug
discrimination and locomotor studies)
demonstrate that N-ethylhexedrone, aPHP, 4-MEAP, MPHP, PV8, or 4-chloroa-PVP produced behavioral effects that
are similar to those of substances with

stimulant effects such as the schedule II
stimulants cocaine and
methamphetamine. Thus, based on the
structural and pharmacological
similarities of N-ethylhexedrone, a-PHP,
4-MEAP, MPHP, PV8, and 4-chloro-aPVP to schedule II stimulant substances
that have demonstrated psychic or
physiological dependence liability, it is
anticipated that the stimulant properties
of N-ethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP
produce psychic dependence liability.
8. Whether the Substance is an
Immediate Precursor of a Substance
Already Controlled Under the CSA: NEthylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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 eightfactor analysis, DEA finds that the facts
and all relevant data constitute
substantial evidence of the potential for
abuse of N-ethylhexedrone, a-PHP, 4MEAP, MPHP, PV8, and 4-chloro-aPVP. As such, DEA hereby proposes to
permanently schedule Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP as
controlled substances 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. N-ethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-PVP have a
high potential for abuse;
2. N-ethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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, a-PHP, 4MEAP, MPHP, PV8, and 4-chloro-a-PVP
under medical supervision.
Based on these findings, the
Administrator concludes that Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, and 4-chloro-a-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, a-PHP, 4-MEAP,
MPHP, PV8, and 4-Chloro-a-PVP
If this rule is finalized as proposed, Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, or 4-chloro-a-PVP would
continue 6 to be subject to the CSA’s

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,
a-PHP, 4-MEAP, MPHP, PV8, and 4-
chloro-a-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, aPHP, 4-MEAP, MPHP, PV8, or 4-chloroa-PVP. There are currently 34 unique
registrations authorized to handle Nethylhexedrone, a-PHP, 4-MEAP,
MPHP, PV8, or 4-chloro-a-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, a-PHP, 4MEAP, MPHP, PV8, or 4-chloro-a-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, aPHP, 4-MEAP, MPHP, PV8, and 4chloro-a-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.
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.

SUMMARY:
VerDate Sep<11>2014
16:52 Jul 15, 2021
Jkt 253001
The Namekagon and St. Croix Rivers
flow through some of the most scenic
and least developed country in the
Upper Midwest. The free-flowing
character and exceptional water quality
of these waterways serve as a unique
ecological corridor in northwest
Wisconsin and eastern Minnesota that
sustains a diversity of aquatic and
terrestrial wildlife and habitats.
In 1968, to preserve, protect, and
enhance this unique national resource
for the benefit and enjoyment of present
and future generations, Congress
established the St. Croix National
Scenic Riverway, a 230-mile long
protected area that includes the
Namekagon River, as one of the original
eight rivers protected under the national
Wild and Scenic Rivers Act. In 1972, the
Lower St. Croix National Scenic
Riverway was added to the National
Wild and Scenic Rivers System.
Together, these areas form the Riverway.
Today, the rivers continue to flow
unimpeded for considerable distances
as they have for millennia, through the
river corridor, growing and changing in
character from their headwaters to the
St. Croix’s confluence with the
Mississippi. The Riverway offers
exceptional recreational opportunities
for visitors to paddle, boat, camp, hike,
fish, explore, and find solitude in a
natural setting close to the major
metropolitan area of Minneapolis-Saint
Paul. The National Park Service (NPS)
and state partners work with local
communities to maintain the aquatic,
cultural, recreational, riparian, scenic–
aesthetic, and geologic values of the
rivers for the benefit and enjoyment of
more than 600,000 annual visitors.
Cable Connector Trail Environmental
Assessment
The NPS proposes to construct a 0.25mile connector trail through the
PO 00000
Frm 00039
Fmt 4702
Sfmt 4702

Riverway near Cable, Wisconsin. The
trail would be designed for hiking, trail
running, and bicycle and electric
bicycle (e-bike) use, and silent sports in
the winter such as fat-tire bicycling,
snowshoeing, and cross-country skiing.
It would be the first trail at the Riverway
open to bicycle use. Construction of the
trail would respond to a specific
opportunity identified by the NPS and
local partners to create a link across
public land to provide direct access to
the Riverway and new recreational
opportunities within the Riverway and
on the Chequamegon Area Mountain
Bike Association (CAMBA) trail
network in Bayfield County, Wisconsin.
The trail would be built from the end of
a segment of CAMBA’s Wild River Trail
on a former railroad grade near the
Town of Cable, connecting to Parker
Road. The trail would provide a critical
link to adjoining trails and would serve
an important role providing
connectivity for several local trail
running and biking events that start or
finish in the Cable area. The bare soil
trail would be built using sustainable
trail construction techniques to protect
natural and cultural resources. The trail
would utilize landforms and natural
features exhibiting the natural beauty of
the area and would feature a slight
crown, shallow grades, open sight lines,
and gentle turns to support user safety,
provide adequate drainage to minimize
braiding, seasonal muddiness, and
erosion, and reduce the overall
maintenance costs associated with more
complex trail features. Signage would
clearly indicate allowed uses on the
trail. Equestrian and motorized use
would not be allowed.
On September 22, 2020, the NPS
published the Cable Connector Trail
Environmental Assessment (EA). The
EA describes one action alternative (the
preferred alternative) and the no-action
alternative. Under the preferred
alternative, the NPS would construct the
0.25 mile Cable Connector Trail to
accommodate bicycle and e-bike use.
The EA evaluates (1) the suitability of
the Cable Connector Trail for bicycle
and e-bike use; and (2) life cycle
maintenance costs, safety
considerations, methods to prevent or
minimize user conflict, and methods to
protect natural and cultural resources
and mitigate impacts associated with
bicycle and e-bike use on the trail. The
EA contains a full description of the
purpose and need for taking action, the
alternatives considered, a map of the
affected area, and the environmental
impacts associated with the project.

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 https://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 https://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 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. 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:
---------------------------------------------------------------------------
\6\ N-ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-
chloro-[alpha]-PVP are currently subject to schedule I controls on a
temporary basis, pursuant to 21 U.S.C. 811(h). 84 FR 34291, July 18,
2019. An order extending the temporary scheduling of N-
ethylhexedrone, [alpha]-PHP, 4-MEAP, MPHP, PV8, and 4-chloro-
[alpha]-PVP for one year is published elsewhere in this issue of the
Federal Register, on the same day as this notice of proposed
rulemaking.
---------------------------------------------------------------------------

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.
