SUPPLEMENTARY INFORMATION:
I. Background
The United States is a party to the 1971 Convention on Psychotropic
Substances (Psychotropic Convention). Article 2 of the Psychotropic
Convention provides that if a party to the convention or WHO has
information about a substance, which in its opinion may require
international control or change in such control, it shall so notify the
Secretary-General of the United Nations (the U.N. Secretary-General)
and provide the U.N. Secretary-General with information in support of
its opinion.
Section 201 of the CSA (21 U.S.C. 811) (Title II of the
Comprehensive Drug Abuse Prevention and Control Act of 1970) provides
that when WHO notifies the United States under Article 2 of the
Psychotropic Convention that it has information that may justify adding
a drug or other substances to one of the schedules of the Psychotropic
Convention, transferring a drug or substance from one schedule to
another, or deleting it from the schedules, the Secretary of State must
transmit the notice to the Secretary of Health and Human Services
(Secretary of HHS). The Secretary of HHS must then publish the notice
in the Federal Register and provide opportunity for interested persons
to submit comments that will be considered by HHS in its preparation of
the scientific and medical evaluations of the drug or substance.
II. WHO Notification
The Secretary of HHS received the following notice from WHO (non-
relevant text removed):
Ref.: C.L.xx.2017
The World Health Organization (WHO) presents its compliments to
Member States and Associate Members and has the pleasure of
informing that the Thirty-ninth Expert Committee on Drug Dependence
(ECDD) will meet in Geneva from 6 to 10 November 2017 to review a
number of substances with potential for dependence, abuse and harm
to health, and will make recommendations to the U.N. Secretary-
General, on the need for and level of international control of these
substances.
At its 126th session in January 2010, the Executive Board
approved the publication ``Guidance on the WHO review of
psychoactive substances for international control'' (EB126/2010/
REC1, Annex 6) which requires the Secretariat to request relevant
information from Ministers of Health in Member States to prepare a
report for submission to the ECDD. For this purpose, a questionnaire
was designed to gather information on the legitimate use, harmful
use, status of national control and potential impact of
international control for each substance under evaluation. Member
States are invited to collaborate, as in the past, in this process
by providing pertinent information as requested in the questionnaire
and concerning substances under review.
It would be appreciated if a person from the Ministry of Health
could be designated as the focal point responsible for coordinating
and answering the questionnaire. (non relevant information from
letter not shown, see letter for text not shown here) The designated
focal point, and only this person, should access and complete the
questionnaires:
1. Ocfentanil
2. Furanyl fentanyl (Fu-F)
3. Acryloylfentanyl (Acrylfentanyl)
4. Carfentanil
5. 4-fluoroisobutyrfentanyl (4-FIBF)
6. Tetrahydrofuranylfentanyl (THF-F)
7. 4-fluoroamphetamine (4-FA)
8. AB-PINACA
9. AB-CHMINACA
10. 5F-PB-22
11. UR-144
12. 5F-ADB
13. Etizolam
14. Pregabalin
15. Tramadol
16. Cannabidiol
17. Ketamine
PDF versions of the questionnaire in English, French and Spanish
may be downloaded from the link http://www.who.int/medicines/access/controlled-substances/ecdd/en/. Please note that these versions are
for reference only and all questionnaires must be answered through
the online system. Further clarification regarding the questionnaire
may be obtained from the Secretariat by emailing:
[email protected].
Replies to the questionnaire must reach the Secretariat by 30
September 2017 in order to facilitate analyses and preparation of
the report before the planned meeting. Where there is a competent
National Authority under the International Drug Control Treaties, it
is kindly requested that the questionnaire be completed in
collaboration with such body.
The summary information from the questionnaire will be published
online as part of the report on the Web site for the Thirty-ninth
ECDD linked to the Department of Essential Medicines and Health
Products (EMP). The provisional agenda of the Thirty-ninth ECDD and
the list of psychoactive substances under review are also published
on Thirty-ninth ECDD Web page: http://www.who.int/medicines/access/controlled-substances/ecdd/en/.
Member States are also encouraged to provide any additional
relevant information (unpublished or published) that is available on
these substances to: [email protected]. This information will
be an invaluable contribution to the ECDD and all submissions will
be treated as confidential.
The World Health Organization takes this opportunity to renew to
Member States and Associate Members the assurance of its highest
consideration.
GENEVA, 7 July 2017
FDA has verified the Web site addresses contained in the WHO
notice, as of the date this document publishes in the Federal Register,
but Web sites are subject to change over time.
III. Substances Under WHO Review
Ocfentanil is a synthetically produced opioid that is structurally
related to fentanyl and approximately equipotent in effect. Reported
risks associated with use of ocfentanil include development of opioid
use disorder, overdose, and fatal overdose. It has no approved medical
use in the United States and is not a controlled substance in the
United States under the CSA.
Furanyl fentanyl (Fu-F) is a potent clandestinely produced
synthetic opioid that is an analog of fentanyl. Evidence suggests that
the pattern of abuse of fentanyl analogues, including furanyl fentanyl,
parallels that of heroin and
[[Page 37868]]
prescription opioid analgesics. Fu-F produces the typical opioid
effects that include respiratory depression and loss of consciousness.
Seizures of Fu-F have been encountered in powder form. Fu-F has been
connected to fatal overdoses, in which intravenous routes of
administration are documented. It has no approved medical use in the
United States. On November 29, 2016, the Drug Enforcement
Administration (DEA) issued a final order to temporarily schedule Fu-F
and its isomers, esters, ethers, salts and salts of isomers, esters and
ethers, into Schedule I pursuant to the temporary scheduling provisions
of the CSA.
Acryloylfentanyl (Acrylfentanyl) belongs to the 4-anilidopiperidine
class of synthetic opioids and is similar in structure to fentanyl.
Acryloylfentanyl is a clandestinely produced analog of fentanyl and
sold illegally as a research chemical on several Web sites.
Acryloylfentanyl has also been associated with adverse events typically
associated with opioid use such as respiratory depression, anxiety,
constipation, tiredness, hallucinations, and withdrawal. The use of
acryloylfentanyl has also been linked to the development of opioid use
disorder, overdose, and fatal overdose. Acryloylfentanyl has no
commercial or medical uses. On July 14, 2017, the DEA issued a
temporary order to temporarily schedule acryloylfentanyl, its isomers,
esters, ethers, salts and salts of isomers, esters, and ethers, into
Schedule I pursuant to the temporary scheduling provisions of the CSA.
Carfentanil, also known as 4-carbomethoxyfentanyl, is an extremely
potent synthetic opioid that is similar in structure to and
approximately 100 times more potent than fentanyl as an analgesic. At
one time legitimately produced, carfentanil is no longer manufactured,
marketed, or used in the United States; it is approved by FDA for use
under restricted conditions by veterinarians as a immobilizing agent
for certain large animals. Illicitly produced carfentanil is a
particularly harmful fentanyl analogue that is also being laced into
heroin or sold by itself and trafficked in the United States. It is not
approved for human use. Drug seizure data indicate that carfentanil is
typically used in small doses to cut heroin and other illicitly abused
drugs. The significant risk to public health associated with
carfentanil use stems from its respiratory depressive effects with very
small amounts. Several fatalities have been reported as the result of
carfentanil overdoses. On October 28, 1988, the DEA placed carfentanil
in Schedule II of the CSA.
4-fluoroisobutyrfentanyl is a clandestinely produced synthetic
opioid that is an analog of fentanyl. It has [micro]-receptor agonist
activity similar to that of fentanyl. This would result in effects
associated with opioid agonists such as analgesia, respiratory
depression, anxiety, constipation, tiredness, hallucinations,
withdrawal, the development of opioid use disorder, overdose, and fatal
overdose. The use of 4-fluoroisobutyrfentanyl has been implicated in
several cases of overdose and fatal overdoses. 4-fluoroisobutyrfentanyl
has not been approved for medical use in the U.S. On May 3, 2017, the
DEA issued a temporary order to temporarily schedule 4-
fluoroisobutyrfentanyl, its isomers, esters, ethers, salts and salts of
isomers, esters and ethers, into Schedule I pursuant to the temporary
scheduling provisions of the CSA.
Tetrahydrofuranylfentanyl (THF-F) is a synthetic opioid that is an
analog of fentanyl. It has [micro]-receptor agonist activity similar to
that of fentanyl, resulting in effects associated with opioid agonists
such as analgesia, respiratory depression, anxiety, constipation,
tiredness, hallucinations, withdrawal, the development of opioid use
disorder, overdose, and fatal overdose. THF-F is not approved for
medical use or controlled in the United States under the CSA.
4-Fluoroamphetamine (4-FA) is a psychoactive substance of the
phenethylamine and substituted amphetamine chemical classes and
produces stimulant effects. WHO reports that 4-FA is clandestinely
produced, and its use is associated with fatal and non-fatal
intoxications. 4-FA was reviewed at the 37th ECDD (2015) and, while not
placed under international control due to insufficient data, was kept
under surveillance. 4-FA is not approved for medical use in the United
States and it is not controlled under the CSA.
AB-PINACA is a clandestinely produced synthetic cannabinoid agonist
approximately 1.5 times as potent as delta-9-tetrahydrocannabinol.
Adverse effects produced by cannabinoid agonists include tachycardia,
agitation, hallucination, chest pain, seizure, anxiety, acute
psychosis, and death. AB-PINACA has been detected in illicit synthetic
cannabinoid substances, and reported in cases of overdose and
hospitalizations. It has not been approved for medical use in the
United States. On January 27, 2017, the DEA published a Notice of
Proposed Rulemaking to permanently control AB-PINACA as a Schedule I
substance under the CSA.
AB-CHMINACA is a clandestinely produced synthetic cannabinoid
agonist that is approximately 16 times more potent than delta-9-
tetrahydrocannabinol. Adverse effects produced by cannabinoid agonists
include tachycardia, agitation, hallucination, chest pain, seizure,
anxiety, acute psychosis, and death. AB-CHMINACA has been detected in
illicit synthetic cannabinoid substances and found in cases of overdose
and hospitalizations. AB-CHMINACA has not been pre-reviewed or
critically reviewed by the WHO. On January 27, 2017, the DEA published
a Notice of Proposed Rulemaking to permanently control AB-CHMINACA as a
Schedule I substance under the CSA.
5F-PB-22 is a synthetic cannabinoid agonist with similar effects to
delta-9-tetrahydrocannabinol, one of the main psychoactive components
of cannabis. Adverse effects produced by cannabinoid agonists include
tachycardia, agitation, hallucination, chest pain, seizure, anxiety,
acute psychosis, and death. 5F-PB-22 is clandestinely produced. It has
been found laced on plant material and marketed as herbal products, and
is smoked for its psychoactive effects. According to the WHO, 5F-PB-22
has been associated with fatal intoxications. On September 6, 2016, the
DEA issued a final rule to permanently place 5F-PB-22 into Schedule I
of the CSA.
UR-144 is a clandestinely produced synthetic cannabinoid agonist.
In general, adverse effects produced by cannabinoid agonists include
tachycardia, agitation, hallucination, chest pain, seizure, anxiety,
and acute psychosis. UR-144 has been detected in herbal smoking blends
that are sold as herbal incense. In June 2014, the 36th (2014) ECDD
reviewed UR-144 and recommended that it be placed under surveillance.
On May 11, 2016, the DEA issued a final rule to permanently schedule
UR-144 into Schedule I of the CSA.
5F-ADB is a clandestinely produced synthetic cannabinoid agonist.
In general, adverse effects produced by cannabinoid agonists include
tachycardia, agitation, hallucination, chest pain, seizure, anxiety,
and acute psychosis. 5F-ADB has been identified in overdose and/or
cases involving death attributed to their abuse. Adverse health effects
reported from incidents involving 5F-ADB and other synthetic
cannabinoids have included: Nausea, persistent vomiting, agitation,
altered mental status, seizures, convulsions, loss of consciousness,
and/or cardio toxicity. On April 10, 2017, the DEA issued a temporary
scheduling order to
[[Page 37869]]
temporarily schedule 5F-ADB, its isomers, esters, ethers, salts and
salts of isomers, esters, and ethers into Schedule I pursuant to the
temporary scheduling provisions of the CSA.
Etizolam belongs to a class of substances known as benzodiazepines.
Benzodiazepines produce central nervous system depression and are
commonly used to treat insomnia, anxiety, and seizure disorders.
Etizolam is currently prescribed in some countries to treat generalized
anxiety disorder with depressive symptoms, but is not approved for
medical use or controlled in the United States under the CSA. WHO
reported that non-fatal intoxications that include cases of driving
under the influence of drugs have been linked to etizolam. The ECDD at
its 37th (2015 meeting reviewed etizolam and recommended that a
critical review of etizolam is warranted.
Pregabalin is an anticonvulsant-type drug used to treat pain
generated from the nervous system. It is available as an oral capsule
and oral solution and approved for medical use in the United States for
the management of neuropathic pain associated with diabetic peripheral
neuropathy, post-herpetic neuralgia, and adjunctive therapy for partial
onset seizures, fibromyalgia, and neuropathic pain associated with
spinal cord injury. Although the mechanism of action of pregabalin is
unknown, studies in animals suggest that binding to the nervous system
tissues may be involved in its pain-relieving and anti-seizure effects.
Pregabalin binds with high affinity to the alpha 2-delta receptor site
(a subunit of voltage-gated calcium channels) in the central nervous
system. The binding of pregabalin at this site is thought to be
responsible for its therapeutic effect on neuropathic pain. Reports
indicate that patients are self-administering higher than recommended
doses to achieve euphoria, especially patients who have a history of
substance abuse, particularly opioids, and psychiatric illness. While
effects of excessively high doses are generally non-lethal,
gabapentinoids such as pregabalin are increasingly being identified in
post-mortem toxicology analyses. Pregabalin is a Schedule V controlled
substance in the United States under the CSA.
Tramadol is an opioid analgesic that produces its primary opioid-
like action through an active metabolite referred to as the M1
metabolite (O-desmethyltramadol). Tramadol was first approved for
marketing in the United States in 1995 and is available as immediate-
release, extended-release, and combination products for the treatment
of moderate to moderately severe pain. On July 2, 2014, the DEA
published a final rule in the Federal Register controlling tramadol as
a Schedule IV substance of the CSA effective from August 18, 2014.
Tramadol was pre-reviewed by the ECDD at its 28th (1992) and 32nd
(2000) meetings, and critically reviewed at the 33rd (2002) meeting and
not recommended for international control but placed on surveillance.
Tramadol was pre-reviewed again by the ECDD at its 34th (2006) meeting;
however, the ECDD concluded that there was not sufficient evidence to
justify a critical review. At the 36th (2014) meeting, the ECDD
considered updated information on tramadol, but again concluded that
there was insufficient evidence to warrant a critical review.
Cannabidiol (CBD) is one of the active cannabinoids identified in
cannabis. CBD has been shown to be beneficial in experimental models of
several neurological disorders, including those of seizure and
epilepsy. In the United States, CBD-containing products are in human
clinical testing in three therapeutic areas, but no such products are
approved by FDA for marketing for medical purposes in the United
States. CBD is a Schedule I controlled substance under the CSA. At the
37th (2015) meeting of the ECDD, the committee requested that the
Secretariat prepare relevant documentation to conduct pre-reviews for
several substances, including CBD.
Ketamine is classified as a rapid-acting general anesthetic agent
used for short diagnostic and surgical procedures that do not require
skeletal muscle relaxation. It is marketed in the United States as a
solution for injection. Ketamine is controlled in Schedule III of the
CSA in the United States. It is not controlled internationally under
the Convention on Psychotropic Substances or the Single Convention on
Narcotic Drugs. The ECDD reviewed ketamine at its 34th (2006), 35th
(2012), and 36th (2014) meetings. On March 13, 2015, the Commission on
Narcotic Drugs (CND) decided by consensus to postpone the consideration
of a proposal concerning the recommendation to place ketamine in
Schedule IV of the Psychotropic Convention. The CND requested
additional information from the WHO. The ECDD reviewed updated
information at its 37th (2015) meeting and found no reason to recommend
a new pre-review or critical review of ketamine that could potentially
change its standing 2014 recommendation that ketamine should not be
placed under international control.
IV. Opportunity To Submit Domestic Information
As required by section 201(d)(2)(A) of the CSA, FDA, on behalf of
HHS, invites interested persons to submit comments regarding the 17
named drug substances. Any comments received will be considered by HHS
when it prepares a scientific and medical evaluation of these drug
substances. HHS will forward a scientific and medical evaluation of
these drug substances to WHO, through the Secretary of State, for WHO's
consideration in deciding whether to recommend international control/
decontrol of any of these drug substances. Such control could limit,
among other things, the manufacture and distribution (import/export) of
these drug substances and could impose certain recordkeeping
requirements on them.
Although FDA is, through this notice, requesting comments from
interested persons, which will be considered by HHS when it prepares an
evaluation of these drug substances, HHS will not now make any
recommendations to WHO regarding whether any of these drugs should be
subjected to international controls. Instead, HHS will defer such
consideration until WHO has made official recommendations to the
Commission on Narcotic Drugs, which are expected to be made in early
2018. Any HHS position regarding international control of these drug
substances will be preceded by another Federal Register notice
soliciting public comments, as required by section 201(d)(2)(B) of the
CSA.
