    SUPPLEMENTARY INFORMATION:

    I. Background

    The United States is a party to the 1971 Convention on Psychotropic Substances (Psychotropic Convention). Section 201(d)(2)(B) of the CSA (21 U.S.C. 811(d)(2)(B)) provides that when the United States is notified under Article 2 of the Psychotropic Convention that the CND proposes to decide whether to add a drug or other substance to one of the schedules of the Psychotropic Convention, transfer a drug or substance from one schedule to another, or delete it from the schedules, the Secretary of State must transmit notice of such information to the Secretary of Health and Human Services (Secretary of HHS). The Secretary of HHS must then publish a summary of such information in the Federal Register and provide opportunity for interested persons to submit comments. The Secretary of HHS must then evaluate the proposal and furnish a recommendation to the Secretary of State that shall be binding on the representative of the United States in discussions and negotiations relating to the proposal.

    As detailed in the following paragraphs, the Secretary of State has received notification from the Secretary-General of the United Nations (the Secretary-General) regarding eight substances to be considered for control under the Psychotropic Convention. This notification reflects the recommendation from the 38th WHO Expert Committee for Drug Dependence (ECDD), which met in November 2016. In the Federal Register of September 19, 2016 (81 FR 64162), FDA announced the WHO ECDD review and invited interested persons to submit information for WHO's consideration.

    The full text of the notification from the Secretary-General is provided in section II of this document. Section 201(d)(2)(B) of the CSA requires the Secretary of HHS, after receiving a notification proposing scheduling, to publish a notice in the Federal Register to provide the opportunity for interested persons to submit information and comments on the proposed scheduling action.

    The United States is also a party to the 1961 Single Convention on Narcotic Drugs (1961 Single Convention). The Secretary of State has received a notification from the Secretary-General regarding two substances to be considered for control under this convention. The CSA does not require HHS to publish a summary of such information in the Federal Register. Nevertheless, in an effort to provide interested and affected persons an opportunity to submit comments regarding the WHO recommendations for narcotic drugs, the notification regarding these substances is also included in this Federal Register notice. The comments will be shared with other relevant Agencies to assist the Secretary of State in formulating the position of the United States on the control of these substances. The HHS recommendations are not binding on the representative of the United States in discussions and negotiations relating to the proposal regarding control of substances under the 1961 Single Convention.

    II. United Nations Notification

    The formal notification from the United Nations that identifies the drug substances and explains the basis for the recommendations is reproduced as follows (non-relevant text removed):

    NAR/CL.8/2016

    Annex II

    Extract From the Report of the 38th Expert Committee on Drug Dependence

    Substances recommended to be scheduled in Schedule I and Schedule IV of the Single Convention on Narcotic Drugs (1961), as amended by the 1972 Protocol:

    U-47700

    Chemically, U-47700 is 3,4-dichloro-N-(2-dimethylamino-cyclohexyl)-N-methyl-benzamide. U47700 has two chiral centres resulting in four isomers; cis and trans conformations each have two enantiomers [cis: are (1R,2R), and (1S,2S); trans are (1R,2S) and (1S,2R)].

    U-47700 was not previously pre-reviewed or critically reviewed by the Committee. A direct critical review is proposed based on information brought to the attention of the WHO that U-47700 is clandestinely manufactured, poses risk to public health and society, and has no recognized therapeutic use by any Party.

    U-47700 (3,4-dichloro-N-(2-dimethylamino-cyclohexyl)-N-methyl-benzamide) is a compound liable to similar abuse and with similar ill-effects to controlled opioids such as morphine and AH-7921 that are included in Schedule I of the 1961 Single Convention on Narcotic Drugs. It has no recorded therapeutic use, and its use has resulted in fatalities. There is sufficient evidence that it is being or is likely to be abused so as to constitute a public health and social problem warranting the placing of the substance under international control. Thus, because it meets the required condition of similarity, it is recommended that U-47700 be placed in Schedule I of the Single Convention on Narcotic Drugs, 1961, as consistent with Article 3, paragraph 3 (iii) of that Convention in that the substance is liable to similar abuse and productive of similar ill effects as drugs in Schedule I.

    Butyrfentanyl

    Chemically, butyrfentanyl is N-phenyl-N-[1-(2-phenylethyl)-4-piperidinyl]butanamide.

    Butyrfentanyl has not been previously pre-reviewed or critically reviewed by the Committee. A direct critical review is proposed based on information brought to the attention of the WHO that butyrfentanyl is clandestinely manufactured, poses risk to public health and society, and has no recognized therapeutic use by any Party.

    Butyrfentanyl (N-phenyl-N-[1-(2-phenylethyl)-4-piperidinyl]butanamide) is a compound liable to similar abuse and with similar ill-effects to controlled opioids such as morphine and fentanyl that are included in Schedule I of the 1961 Single Convention on Narcotic Drugs. It can be converted into fentanyl as well. It has no recorded therapeutic use and its use has resulted in fatalities. There is sufficient evidence that it is being or is likely to be abused so as to constitute a public health and social problem warranting the placing of the substance under international control. Thus, because it meets either of the required conditions of similarity or convertibility, it is recommended that butyrfentanyl be placed in Schedule I of the Single Convention on Narcotic Drugs, 1961, as consistent with Article 3, paragraph 3 (iii) of that Convention in that the substance is liable to similar abuse and productive of similar ill effects as drugs in Schedule I.

    Substances recommended to be scheduled in Schedule II of the Convention on Psychotropic Substances (1971):

    4-MEC (4-Methylethcathinone)

    Chemically, 4-methylethcathinone (4-MEC) is 2-(ethylamino)-1-(4-methylphenyl)propan-1-one. 4-MEC has a chiral centre giving rise to an enantiomeric pair of (S)-4-MEC and (R)-4-MEC isomers.Start Printed Page 3329

    A critical review report on 4-MEC was discussed in June 2014 at the 36th meeting of the WHO Expert Committee on Drug Dependence. The Committee recommended that 4-MEC not be placed under international control at that time due to insufficiency of data regarding dependence, abuse and risks to public health, but be kept under surveillance. 4-MEC continues to appear as a psychostimulant with monoamine transporter activity with indications of abuse liability. New data have emerged from in vitro and in vivo studies since the 36th ECCD meeting that has prompted the current critical review.

    The Committee considered that the degree of risk to public health and society associated with the abuse of 4-MEC (2-(ethylamino)-1-(4-methylphenyl)propan-1-one) is substantial. Therapeutic usefulness has not been recorded. It recognized that it has similar abuse and similar ill-effects as substances in Schedule II of the UN 1971 Convention on Psychotropic Substances. The Committee considered that there is sufficient evidence that 4-MEC is being or is likely to be abused so as to constitute a public health and social problem warranting the placing of the substance under international control. As per the Guidance on the WHO review of psychoactive substances for international control, higher regard was accorded to the substantial public health risk than to the lack of therapeutic usefulness. The Committee recommended that 4-MEC be placed in Schedule II under the UN 1971 Convention on Psychotropic Substances.

    Ethylone

    Chemically, ethylone is 1-(2H-1,3-benzodioxol-5-yl)-2-(ethylamino)propan-1-one. It is a chiral compound with isomers, and its hydrochloride salt can exist in two conformations (polymorphs) at the C-C bond linking the side chain to the aromatic ring.

    Ethylone was not previously pre-reviewed or critically reviewed. A direct critical review is proposed based on information brought to the attention of the WHO that ethylone is clandestinely manufactured, poses serious risk to public health and society, and has no recognized therapeutic use by any Party.

    The Committee considered that the degree of risk to public health and society associated with the abuse of ethylone (1-(2H-1,3-benzodioxol-5-yl)-2-(ethylamino)propan-1-one) is substantial. Therapeutic usefulness has not been recorded. It recognized that it has similar abuse and similar ill-effects as substances in Schedule II of the UN 1971 Convention on Psychotropic Substances. The Committee considered that there is sufficient evidence that ethylone is being or is likely to be abused so as to constitute a public health and social problem warranting the placing of the substance under international control. As per the Guidance on the WHO review of psychoactive substances for international control, higher regard was accorded to the substantial public health risk than to the lack of therapeutic usefulness. The Committee recommended that ethylone be placed in Schedule II under the UN 1971 Convention on Psychotropic Substances.

    Pentedrone (α-Methylaminovalerophenone)

    Chemically, pentedrone is 2-(methylamino)-1-phenylpentan-1-one. It has a chiral centre giving rise to two stereoisomers, (S)- and (R)- pentedrone.

    Pentedrone has not been previously reviewed or critically reviewed by the Expert Committee on Drug Dependence of the WHO. A direct critical review is proposed based on information brought to WHO's attention that pentedrone is clandestinely manufactured, poses serious risk to public health and society, and has no recognized therapeutic use by any Party.

    The Committee considered that the degree of risk to public health and society associated with the abuse of pentedrone (2-(methylamino)-1-phenylpentan-1-one) is substantial. Therapeutic usefulness has not been recorded. It recognized that it has similar abuse and similar ill-effects as substances in Schedule II of the UN 1971 Convention on Psychotropic Substances. The Committee considered that there is sufficient evidence that pentedrone is being or is likely to be abused so as to constitute a public health and social problem warranting the placing of the substance under international control. As per the Guidance on the WHO review of psychoactive substances for international control, higher regard was accorded to the substantial public health risk than to the lack of therapeutic usefulness. The Committee recommended that pentedrone be placed in Schedule II under the UN 1971 Convention on Psychotropic Substances.

    Ethylphenidate (EPH)

    Chemically, ethylphenidate is ethyl phenyl(piperidin-2-yl)acetate.

    Ethylphenidate was not previously pre-reviewed or critically reviewed. A direct critical review is proposed based on information brought to the attention of the WHO that ethylphenidate is clandestinely manufactured, poses serious risk to public health and society, and has no recognized therapeutic use by any Party.

    The Committee considered that the degree of risk to public health and society associated with the abuse of ethylphenidate (ethyl phenyl(piperidin-2-yl)acetate) is substantial. Therapeutic usefulness has not been recorded. It recognized that it has similar abuse and similar ill-effects as substances in Schedule II of the UN 1971 Convention on Psychotropic Substances. The Committee considered that there is sufficient evidence that ethylphenidate is being or is likely to be abused so as to constitute a public health and social problem warranting the placing of the substance under international control. As per the Guidance on the WHO review of psychoactive substances for international control, higher regard was accorded to the substantial public health risk than to the lack of therapeutic usefulness. The Committee recommended that ethylphenidate be placed in Schedule II under the UN 1971 Convention on Psychotropic Substances.

    MPA (Methiopropamine)

    Chemically, methiopropamine is N-methyl-1-(thiophen-2-yl)propan-2-amine. It has a chiral centre with two enantiomers.

    Methiopropamine was previously critically reviewed by the Committee at its 36th meeting. Owing to the insufficiency of data regarding dependence, abuse and risks to public health, the Committee recommended that methiopropamine not be placed under international control but be kept under surveillance. Subsequent data collected from the literature and from different countries indicated that this substance may cause substantial harm and that it has no medical use warranting an updated critical review.

    The Committee considered that the degree of risk to public health and society associated with the abuse of methiopropamine (N-methyl-1-(thiophen-2-yl)propan-2-amine) is substantial. Therapeutic usefulness has not been recorded. It recognized that it has similar abuse and similar ill-effects as substances in Schedule II of the UN 1971 Convention on Psychotropic Substances.

The Committee recommended that XLR-11 be placed in Schedule II under the UN 1971 Convention on Psychotropic Substances.

    Substance recommended for critical review:

    3-Methylmethcathinone (3-methyl-N-methylcathinone; 3-MMC)

    Chemically, 3-MMC is 2-(methylamino)-1-(3-methylphenyl)propan-1-one. 3-MMC contains a chiral centre at the C-2 carbon of the propane sidechain, so two enantiomers exist: (R)-3-MMC and (S)-3-MMC.

    3-MMC was not previously pre-reviewed or critically reviewed. A direct critical review is proposed based on information brought to the attention of the WHO that 3-MMC is clandestinely manufactured, poses serious risk to public health and society, and has no recognized therapeutic use by any Party.

    The Committee deliberated at length regarding the information available pertinent to the degree of risk to public health and society associated with the abuse of 3-MMC (2-(methylamino)-1-(3-methylphenyl)propan-1-one). The Committee decided that the information as currently provided, and the ensuing discussions that had occurred, were inadequate to form a consensus and confident recommendation regarding the scheduling of 3-MMC. As per paragraph 59 of the Guidance on the WHO review of psychoactive substances for international control, and as supported by its procedural reference to the Thirty-fourth report of the WHO Expert Committee on Drug Dependence, “. . . in cases where additional information concerning the substance under review is required, the Committee may decide that it will reach a final opinion at a subsequent meeting.” “. . . then it should request another critical review in order to refer the matter to a subsequent Expert Committee.” As directed by these guidelines, the Committee requested that the Secretariat arrange another critical review of 3-MMC at a subsequent Expert Committee.

    Substance recommended for surveillance:

    JWH-073

    Chemically, JWH-073 is (1-butyl-1H-indol-3-yl)(1-naphthyl)methanone.

    During its 36th meeting, the WHO Expert Committee on Drug Dependence discussed the critical review report on JWH-073 and concluded that owing to the current insufficiency of data regarding dependence, abuse and risks to public health, JWH-073 should not be placed under international control at that time but be kept under surveillance. New information on its pharmacology and abuse potential warranted an update of the critical review report for discussion at the 38th ECDD.

    The available pharmacodynamic data related to JWH-073 (1-butyl-1H-indol-3-yl)(1-naphthyl)methanone) demonstrates that this substance has the capacity to produce some effects similar to its homologue, JWH-018, that is included in Schedule II of the UN 1971 Convention on Psychotropic Substances. However, the data currently available does not make it possible to establish a direct link between JWH-073 abuse and appearance of public health and social problems that would be a requirement for placing this substance under international control. It is therefore recommended not to place JWH-073 under international control but to continue to keep it under surveillance.

    Update on Cannabis and Cannabis resin:

    At the 37th ECDD meeting the Committee requested that Secretariat begin collecting data towards a pre-review of cannabis, cannabis resin, extracts and tinctures of cannabis at a future meeting. Consistent with this request, two updates on the scientific literature on cannabis were prepared and subsequently presented to the Expert Committee. Following its deliberations the Committee noted that the current Schedule I of the 1961 Convention groups together cannabis and cannabis resin, extracts and tinctures of cannabis. Cannabis plant and cannabis resin are also in Schedule IV of the 1961 Convention. The Committee further noted that there are natural and synthetic cannabinoids in Schedule I and Schedule II of the 1971 Convention. The Committee recognized:

    —An increase in the use of cannabis and its components for medical purposes;

    —The emergence of new cannabis-related pharmaceutical preparations for therapeutic use;

    —Cannabis has never been subject to a formal pre-review or critical review by the ECDD.

    The Committee requested that the Secretariat prepare relevant documentation in accordance with the Guidance on the WHO review of psychoactive substances for international control in order to conduct pre-reviews for the following substances:

    —Cannabis plant and cannabis resin;

    —Extracts and tinctures of cannabis;

    —Delta-9-tetrahydrocannabinol (THC);

    —Cannabidiol (CBD);

    —Stereoisomers of THC.

    The Committee recommended that these pre-reviews be evaluated at a specific ECDD meeting dedicated to cannabis and its component substances to be held within the next eighteen months from the 38th meeting.

    The purpose of the pre-review is to determine whether current information justifies an Expert Committee critical review. The categories of information for evaluating substances in pre-reviews are identical to those used in critical reviews. The pre-review is a preliminary analysis, and findings at this stage should not determine whether the control status of a substance should be changed.

    III. Discussion

    Although WHO has made specific scheduling recommendations for each of the drug substances, the CND is not obliged to follow the WHO recommendations. Options available to the CND for substances considered for control under the Psychotropic Convention include the following: (1) Accept the WHO recommendations; (2) accept the recommendations to control, but control the drug substance in a schedule other than that recommended; or (3) reject the recommendations entirely.

    U-47700 is a synthetic opioid drug developed in the 1970s. U-47700 is structurally related to the opioid AH-7921. U-47700 is selective for the µ-opioid receptor. U-47700 has never been studied on humans, but would be expected to produce effects similar to those of other potent opioid agonists, including strong analgesia, sedation, euphoria, constipation, itching, and respiratory depression which could be harmful or fatal. Overdoses and Start Printed Page 3331overdose fatalities have been directly attributed to U-47700 misuse. There have been reports of U-47700 being encountered in counterfeit pills. On November 14, 2016, the U.S. Drug Enforcement Administration (DEA) temporarily scheduled U-47700 into schedule I pursuant to the temporary scheduling provisions of the Controlled Substances Act. As such, additional permanent controls will be necessary to fulfill U.S. obligations if U-47700 is controlled under Schedule I of the 1961 Single Convention.

    Butyrfentanyl (butyrylfentanyl) is a synthetic opioid and analog of fentanyl. Fentanyl is controlled in Schedule II of the CSA, and an active ingredient in drug products approved for medical use and marketed in the United States. Butyrylfentanyl has a pharmacological profile similar to that of fentanyl and other µ-opioid receptor agonists. Risks associated with abuse of butyrylfentanyl include development of substance use disorder, overdose, and death similar to that of other µ-opioid agonists. The DEA is aware of at least 40 confirmed fatalities associated with butyrylfentanyl. It has no approved medical use in the United States. On May 12, 2016, butyrylfentanyl was temporarily placed into Schedule I of the CSA for 2 years upon finding that it posed an imminent hazard to the public safety. The Attorney General, though, may extend this temporary scheduling for up to 1 year. As such, additional permanent controls will be necessary to fulfill U.S. obligations if butyrylfentanyl is controlled under Schedule I of the 1961 Single Convention.

    4-Methylethcathinone (4-MEC), 3-Methylmethcathinone (3-methyl-N-methylcathinone; 3-MMC): 3-methyl-methcathinone (3-MMC), pentedrone, and ethylone (3,4-methylenedioxy-N-ethylcathinone; bk-MDEA; MDEC) are synthetic cathinones that are structurally and pharmacologically similar to amphetamine, 3-4 methylenedioxymethamphetamine (MDMA), cathinone, and other related substances. These substances are central nervous system stimulants with psychoactive properties similar to Schedule I and II amphetamine type substances. Public health risks associated with the use of synthetic cathinones suggest that these substances are associated with cardiac, psychiatric, and neurological symptoms that may lead to emergency department admissions, violent behaviors causing harm to self or others, or death. 4-MEC and pentedrone have no known medical use in the United States. On March 7, 2014, the DEA published a final order in the Federal Register amending 21 CFR 1308.11(h) to temporarily place 4-MEC and pentedrone into Schedule I of the CSA pursuant to the temporary scheduling provisions of 21 U.S.C. 811(h). On March 4, 2016, the temporary Schedule I status of 4-MEC and pentedrone was extended for 1 year, or until permanent scheduling is completed. Permanent scheduling for 4-MEC and pentedrone was initiated on March 4, 2016, upon publication of the notice of proposed rulemaking. As such, additional permanent controls will be necessary to fulfill U.S. obligations if 4-MEC and pentedrone is controlled under Schedule II of the 1971 Convention on Psychotropic Substances.

    In the United States, ethylone has been sold as the street drug “Molly” and encountered as a replacement for methylone. Ethylone has no known medical use in the United States. As a positional isomer of the controlled drug butylone, ethylone is considered a Schedule I controlled substance under the CSA. As such, no additional controls will be necessary to fulfill U.S. obligations if ethylone is controlled under Schedule II of the 1971 Convention on Psychotropic Substances.

    Ethylphenidate is structurally related to methylphenidate. Methylphenidate is controlled in Schedule IV of the CSA, and an active ingredient in drug products approved for medical use and marketed in the United States. Ethylphenidate is not approved for medical use in the United States. Ethylphenidate is structurally related to methylphenidate are being marketed as novel psychoactive substances with psychoactive effects similar to methylphenidate, therefore posing similar health risks to the users. Ethylphenidate is a controlled substance in several European countries, and is not a controlled substance in the United States under the CSA. As such, additional permanent controls will be necessary to fulfill U.S. obligations if ethylphenidate is controlled under Schedule II of the 1971 Convention on Psychotropic Substances.

    Methiopropamine (MPA) is a structural analogue of the Schedule II controlled substance methamphetamine. Pharmacologically, it functions as a norepinephrine-dopamine reuptake inhibitor and, secondarily, as a serotonin reuptake inhibitor. MPA is a thiophene based analog of methamphetamine. It has stimulant properties as an inhibitor of dopamine, norepinephrine transporters in the central nervous system. MPA is not approved for medical use or controlled in the United States under the CSA. As such, additional permanent controls will be necessary to fulfill U.S. obligations if MPA is controlled under Schedule II of the 1971 Convention on Psychotropic Substances.

    MDMB-CHMICA is an indole-based synthetic cannabinoid that is a potent full agonist at cannabinoid type 1 (CB1) receptors and mimics functionally (biologically) the effects of the structurally unrelated delta-9-tetrahydrocannabinol, a Schedule I substance, and the main active ingredient of marijuana. Synthetic cannabinoids are marketed under the guise of “herbal incense,” and promoted by drug traffickers as legal alternatives to marijuana. MDMB-CHMICA use is associated with serious adverse events including death in several European countries. There are no commercial or approved medical uses for MDMB-CHMICA. MDMB-CHMICA is not controlled under the CSA, but may be treated as a “controlled substance analogue” under the CSA pursuant to 21 U.S.C. 802(32)(A) and 813, and is a controlled substance in the State of Louisiana. As such, additional permanent controls will be necessary to fulfill U.S. obligations if MDMB-CHMICA is controlled under Schedule II of the 1971 Convention on Psychotropic Substances.

    5F-APINACA (5F-AKB48) is a synthetic cannabinoid belonging to a chemical structural class with an indazole core. In vitro studies show that it binds to the CB1 receptors and displays agonist properties in functional assays, suggesting that it would share in vivo effects with delta-9-THC and various synthetic cannabinoids. There are no commercial or medical uses for 5F-APINACA. Synthetic cannabinoids are marketed under the guise of “herbal incense,” and promoted by drug traffickers as legal alternatives to marijuana. SF-APINACA is not a controlled substance under the CSA, but may be treated as a “controlled substance analogue” under the CSA pursuant to 21 U.S.C. 802(32)(A) and 813. As such, additional permanent controls will be necessary to fulfill U.S. obligations if SF-APINACA is controlled under Schedule II of the 1971 Convention on Psychotropic Substances.

    XLR-11 (5-Fluoro-UR-144, 5F-UR-144) is an indole-based synthetic cannabinoid and acts as an agonist at CB1 receptors. Animal studies indicate that it mimics functionally (biologically) the effects of the structurally unrelated delta-9-THC, a Schedule I substance, and the main active ingredient of marijuana and numerous other Start Printed Page 3332Schedule I synthetic cannabinoids. Synthetic cannabinoids are marketed under the guise of “herbal incense,” and promoted by drug traffickers as legal alternatives to marijuana. On May 11, 2016, XLR11 was permanently controlled as a Schedule I substance under the CSA. As such, additional permanent controls will not be necessary to fulfill U.S. obligations if XLR-11 is controlled under Schedule II of the 1971 Convention on Psychotropic Substances.

    FDA, on behalf of the Secretary of HHS, invites interested persons to submit comments on the notifications from the United Nations concerning these drug substances. FDA, in cooperation with the National Institute on Drug Abuse, will consider the comments on behalf of HHS in evaluating the WHO scheduling recommendations. Then, under section 201(d)(2)(B) of the CSA, HHS will recommend to the Secretary of State what position the United States should take when voting on the recommendations for control of substances under the Psychotropic Convention at the CND meeting in March 2017.

    Comments regarding the WHO recommendations for control of U-47700 and Butyrylfentanyl under the 1961 Single Convention will also be forwarded to the relevant Agencies for consideration in developing the U.S. position regarding narcotic substances at the CND meeting.

    IV. Opportunity for Public Meeting

    FDA does not presently plan to hold a public meeting. If any person believes that, in addition to written comments, a public meeting would contribute to the development of the U.S. position on the substances to be considered for control under the Psychotropic Convention, a request for a public meeting and the reasons for such a request should be sent to James R. Hunter (see FOR FURTHER INFORMATION CONTACT) on or before January 23, 2017.
