SUPPLEMENTARY INFORMATION: In this rule, the Drug Enforcement Administration (DEA) is permanently scheduling the following nine controlled substances including their isomers, esters, ethers, salts, and salts of isomers, esters, and ethers whenever the existence of such isomers, esters, ethers, and salts is possible, in schedule I of the Controlled Substances Act (CSA): PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 Federal Register citation * * • meta-fluorofentanyl (N-(3fluorophenyl)-N-(1-phenethylpiperidin4-yl)propionamide), • meta-fluoroisobutyryl fentanyl (N(3-fluorophenyl)-N-(1phenethylpiperidin-4-yl)isobutyramide), • para-methoxyfuranyl fentanyl (N(4-methoxyphenyl)-N-(1phenethylpiperidin-4-yl)furan-2carboxamide), • 3-furanyl fentanyl (N-(1phenethylpiperidin-4-yl)-Nphenylfuran-3-carboxamide), • 2′,5′-dimethoxyfentanyl (N-(1-(2,5dimethoxyphenethyl)piperidin-4-yl)-Nphenylpropionamide), • isovaleryl fentanyl (3-methyl-N-(1phenethylpiperidin-4-yl)-Nphenylbutanamide), • ortho-fluorofuranyl fentanyl (N-(2fluorophenyl)-N-(1-phenethylpiperidin4-yl)furan-2-carboxamide), • alpha′-methyl butyryl fentanyl (2methyl-N-(1-phenethylpiperidin-4-yl)N-phenylbutanamide), and • para-methylcyclopropyl fentanyl (N-(4-methylphenyl)-N-(1phenethylpiperidin-4yl)cyclopropanecarboxamide). 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 (1) on his own motion; (2) at the request of the Secretary of the Department of Health and Human Services (HHS); 1 or (3) on the petition of any interested party.2 This action was initiated on the Attorney General’s own motion, as delegated to the Administrator of the DEA (Administrator), and is supported by, inter alia, a recommendation from the Assistant Secretary for Health of HHS 1 As discussed in a memorandum of understanding entered into by the Food and Drug Administration (FDA) and the National Institute on Drug Abuse (NIDA), FDA acts as the lead agency within HHS in carrying out the Secretary’s scheduling responsibilities under the CSA, with the concurrence of NIDA. 50 FR 9518, Mar. 8, 1985.

This action continues the imposition of the regulatory controls and administrative, civil, and criminal sanctions of schedule I controlled substances on any person who handles or proposes to handle meta-fluorofentanyl, metafluoroisobutyryl fentanyl, paramethoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′-dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′-methyl butyryl fentanyl, and para-methylcyclopropyl fentanyl. Background On February 6, 2018, DEA published an order in the Federal Register (FR) (83 FR 5188) amending 21 CFR 1308.11(h), temporarily placing fentanyl-related substances, as defined in that order, in schedule I of the CSA based upon a finding that these substances pose an imminent hazard to the public safety and pursuant to the temporary scheduling provisions of 21 U.S.C. 811(h). The nine substances named in this final rule meet the existing definition of fentanyl-related substances, as they are not otherwise controlled in any other schedule (i.e., not included under another DEA Controlled Substance Code Number) and are structurally related to fentanyl by one or more of the five modifications listed under the definition. That temporary scheduling order was effective on the date of publication and was based on findings by the former Acting Administrator that the temporary scheduling of these substances was necessary to avoid an imminent hazard to the public safety pursuant to 21 U.S.C. 811(h)(1). Pursuant to 21 U.S.C. 811(h)(2), the temporary control of fentanyl-related substances, a class of substances as defined in the order, as well as these nine specific substances already covered by that order, was set to expire on February 6, 2020. However, on February 6, 2020, as explained in DEA’s April 10, 2020, correcting amendment (85 FR 20155), Congress extended that expiration date until May 6, 2021, by enacting the Temporary Reauthorization and Study of the Emergency Scheduling of Fentanyl Analogues Act (Pub. L. 116–114, sec. 2, 134 Stat. 103). This temporary order was subsequently extended multiple times, most recently on December 29, 2022, through the Consolidated Appropriations Act, 2023, which extended the order until December 31, 2024. Comment: One commenter stated that fentanyl and the list of related substances is a hazard due to the VerDate Sep<11>2014 16:11 Dec 06, 2023 Jkt 262001 overdose deaths that have been occurring. This commenter also referenced the National Institute on Drug Abuse, stating that fentanyl-related overdoses have been increasing in the United States. Lastly, this commenter stated that permanently placing fentanyl and the list of related substances in schedule I would improve public health and allow for regulation of these substances. DEA Response: DEA appreciates the comments in support of this rulemaking. One clarification to note is that fentanyl remains a schedule II substance. This final rule only applies to the fentanyl-related substances that are listed in this final order. Comment: One commenter stated the proposed rule would make it more difficult to produce and distribute these dangerous fentanyl-related substances, which would help combat the opioid epidemic in the United States. This commenter also referenced a news article by National Public Radio, stating that these nine fentanyl-related substances are not currently classified as controlled substances, making it easy to produce and distribute these substances without legal consequences. Lastly, this commenter recognized that this proposal could have significant impacts on the healthcare industry, such as increased oversight and regulation of fentanyl-related substances, which could prevent their misuse and abuse. DEA Response: DEA appreciates the comments in support of this rulemaking. One clarification to note based on the comment above is that, by temporary order on February 6, 2018, DEA placed these nine fentanyl-related substances under schedule I. 83 FR 5188. That temporary order defined a fentanyl-related substance to mean any substance not otherwise controlled in any schedule (i.e., not listed under another DEA Controlled Substance Code Number), and for which no exemption or approval is in effect under section 505 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 355), that is structurally related to fentanyl by one or more of five specified structural modifications. Therefore, these nine fentanyl-related substances are in fact already schedule I controlled substances. The final rule being issued today applies to nine fentanyl-related substances that were the subject of a February 6, 2018, temporary scheduling order. These nine substances will now be listed in 21 CFR 1308.11(b), as specified in the text of the rule that appears below. This final rule should not have a significant impact on the PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 85105 healthcare industry because these nine fentanyl-related substances have no medical use and they have already been added as schedule I controlled substances since 2018. Comment: One commenter discussed the direct and indirect effects on federal and state healthcare from this regulation. The commenter suggested that this regulation will boost federal oversight of manufacturing and disseminating harmful chemicals. In addition, this regulation would limit availability and expected use, ensure protection of residents, and increases confidence in the medical field. In addition, the commenter stated that is critical to restrict the use of ‘‘fentanyl replicates’’ to those who may need them for medical conditions. Lastly, the commenter stated that raising awareness of the risks of abusing these drugs benefits their prevention. DEA Response: DEA appreciates the comments in support of this rulemaking. As mentioned previously, FDA has not approved a marketing application for a drug product containing any of these nine substances for any therapeutic indication. These substances have no medical use in the United States. Comment: One commenter stated that this rule will affect federal healthcare because many federal agencies are trying to tackle the opioid crisis. The commenter discussed the rising number of pediatric deaths from fentanyl in 2021 and the surge in 2018 of fentanyl overdoses among older adolescents as well as in children younger than five. The commenter agrees with this final rule to schedule these fentanyl-related substances. The commenter also stated that fentanyl is highly addictive and that while fentanyl is prescribed for chronic pain or major surgery, it should be a last resort. DEA Response: DEA appreciates the comments in support of this rulemaking. Comment: One commenter agreed with this final rule to make permanent these nine specific fentanyl-related substances rather than continuing multiple temporary extensions. Once finalized, the commenter stated that the federal government could act against anyone handling these substances since over 150 people die each day from a fentanyl-related drug overdose. DEA Response: DEA appreciates the comments in support of this rulemaking. Again, DEA notes that fentanyl is a schedule II controlled substance that can be prescribed for approved medical uses. However, the nine fentanyl-related substances addressed in this rule are already E:\FR\FM\07DER1.SGM 07DER1 85106 Federal Register / Vol. 88, No. 234 / Thursday, December 7, 2023 / Rules and Regulations schedule I controlled substances and none of them have any medical use in the United States. Comment: One commenter stated that fentanyl should be placed in schedule I. The commenter compared this substance to marijuana, which is a schedule I drug and thought it was mind-blowing that fentanyl was not a schedule I substance. It was suggested that the rising number of deaths, the risk to public health, abuse potential, and dependency should classify fentanyl as a schedule I. DEA Response: DEA appreciates this comment. As stated previously, fentanyl remains a schedule II substance. Fentanyl has approved medical uses in the United States. This final rule only applies to the fentanyl-related substances that are listed in this final order. ddrumheller on DSK120RN23PROD with RULES1 Scheduling Conclusion After consideration of the relevant matter presented through public comments, the scientific and medical evaluation and accompanying recommendation of HHS, and after its own eight-factor evaluation, DEA finds that these facts and all other relevant data constitute substantial evidence of the potential for abuse of metafluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′methyl butyryl fentanyl, and paramethylcyclopropyl fentanyl. DEA is permanently scheduling these nine fentanyl-related substances as schedule I controlled substances under the CSA. Determination of Appropriate Schedule The CSA establishes five schedules of controlled substances known as schedules I, II, III, IV, and V. The CSA also specifies the findings required to place a drug or other substance in any particular schedule.3 After consideration of the analysis and recommendation of the Assistant Secretary for HHS and review of all other available data, the Administrator, pursuant to 21 U.S.C. 811(a) and 812(b)(1), finds the following: (1) The abuse potential of metafluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′methyl butyryl fentanyl, and paramethylcyclopropyl fentanyl is associated with each substance’s pharmacological similarity to other 3 21 U.S.C. 812(b). VerDate Sep<11>2014 16:11 Dec 06, 2023 Jkt 262001 schedule I and II mu-opioid receptor agonist substances which have a high potential for abuse. Similar to morphine (schedule II), fentanyl (schedule II), and several schedule I opioid substances that are structurally related to fentanyl, these nine fentanyl-related substances have been shown to bind and act as muopioid receptor agonists; (2) meta-Fluorofentanyl, metafluoroisobutyryl fentanyl, paramethoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′-dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′-methyl butyryl fentanyl, and para-methylcyclopropyl fentanyl, have no currently accepted medical use in treatment in the United States; 4 and (3) There is a lack of accepted safety for use of meta-fluorofentanyl, metafluoroisobutyryl fentanyl, paramethoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′-dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′-methyl butyryl fentanyl, and para-methylcyclopropyl fentanyl under medical supervision. Based on these findings, the Administrator concludes that metafluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′methyl butyryl fentanyl, and paramethylcyclopropyl fentanyl, including their isomers, esters, ethers, salts, and salts of isomers, esters, and ethers whenever the existence of such isomers, esters, ethers, and salts is possible, warrant control in schedule I of the CSA.5 This final rule does not affect the scheduling of fentanyl itself, which 4 Although there is no evidence suggesting that meta-fluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′-dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′methyl butyryl fentanyl, and paramethylcyclopropyl fentanyl have a currently accepted medical use in treatment in the United States, it bears noting that a drug cannot be found to have such medical use unless DEA concludes that it satisfies a five-part test. Specifically, with respect to a drug that has not been approved by FDA, to have a currently accepted medical use in treatment in the United States, all of the following must be demonstrated: i. The drug’s chemistry must be known and reproducible; ii. there must be adequate safety studies; iii. there must be adequate and well-controlled studies proving efficacy; iv. the drug must be accepted by qualified experts; and v. the scientific evidence must be widely available. 57 FR 10499 (1992). 5 21 U.S.C. 812(b)(1).

On February 6, 2018, DEA published an order to temporarily place fentanyl-related substances 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 metafluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′methyl butyryl fentanyl, and paramethylcyclopropyl fentanyl have already established and implemented the systems and processes required to handle these substances. As discussed in the NPRM, there are 108 registrations authorized to handle one or more of the following substances: meta-fluorofentanyl, metafluoroisobutyryl fentanyl, paramethoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′-dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′-methyl butyryl fentanyl, and para-methylcyclopropyl fentanyl, as well as a number of registered analytical labs that are authorized to handle schedule I controlled substances generally. These 108 registrations represent a maximum of 95 small entities. Therefore, DEA conservatively estimates as many as 95 small entities are affected by this rule. A review of the 108 registrations indicates that all entities that currently handle meta-fluorofentanyl, metafluoroisobutyryl fentanyl, paramethoxyfuranyl fentanyl, 3-furanyl fentanyl, 2′,5′-dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha′-methyl butyryl fentanyl, and para-methylcyclopropyl fentanyl, also handle other schedule I controlled substances and have established and implemented (or maintain) the systems and processes required to handle these substances. Therefore, DEA anticipates that this final 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 small entities. Therefore, DEA has concluded that this final 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 action would not result in any federal mandate that may result ‘‘in the expenditure by State, local, and Tribal Governments, in the aggregate, or by the private sector, of $100 million or more (adjusted annually VerDate Sep<11>2014 16:11 Dec 06, 2023 Jkt 262001 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 final rule does not impose a new collection or modify an existing collection of information under the Paperwork Reduction Act of 1995. 44 U.S.C. 3501–3521. Also, this final rule does not impose new or modify existing recordkeeping or reporting requirements on State or local governments, individuals, businesses, or organizations. However, this final rule does require compliance with the following existing OMB collections: 1117–0003, 1117–0004, 1117–0006, 1117–0008, 1117–0009, 1117–0010, 1117–0012, 1117–0014, 1117–0021, 1117–0023, 1117–0029, and 1117–0056. 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. Congressional Review Act This rule is not a major rule as defined by the Congressional Review Act (CRA), 5 U.S.C. 804. Pursuant to the CRA, DEA is submitting a copy of this final rule to both Houses of Congress and to the Comptroller General. Determination To Make Rule Effective Immediately As indicated above, this rule finalizes the schedule I control status of nine substances that has already been in effect. These nine substances all fall within the definition of fentanyl-related substances set forth in the February 6, 2018, temporary scheduling order (83 FR 5188). Through the Temporary Reauthorization and Study of the Emergency Scheduling of Fentanyl Analogues Act, which became law on February 6, 2020, Congress extended the temporary control of fentanyl-related substances until May 6, 2021. This temporary order was subsequently extended multiple times, most recently on December 29, 2022, through the Consolidated Appropriations Act, 2023, which extended the order until December 31, 2024.7 The February 2018 order was effective on the date of publication, and was based on findings by the then-Acting Administrator that the temporary scheduling of the fentanyl-related substances was necessary to avoid an imminent hazard to the public safety pursuant to 21 U.S.C. 811(h)(1). Because this rule 7 Public Law 117–328, Division O, Title VI, Sec. 601. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 finalizes the control status of nine substances that has already been in effect, it does not alter the legal obligations of any person who handles these substances. Rather, it merely makes permanent the current scheduling status and corresponding legal obligations. Therefore, since this rule does not change the current scheduling status and corresponding legal obligations, DEA is making the rule effective on the date of publication in the Federal Register, as any delay in the effective date is unnecessary and would be contrary to the public interest.

Final rule. AGENCY: ACTION: The Department of State (‘‘Department’’) is amending its regulation governing immigrant visas by removing the section which allows a consular officer to conduct an informal evaluation of the family members of an immigrant visa applicant to identify potential grounds of ineligibility. The existing regulation was promulgated in 1952, at a time when a consular officer could more readily assess a family member’s potential qualification for a visa without a formal visa application. Assessing eligibility for an immigrant visa is now a more complex task and not one which can be accomplished accurately with an informal evaluation.

The rule will eliminate 22 CFR 42.68 in its entirety. The regulatory amendment was discussed in detail in the proposed rule, and that discussion is adopted by reference in this final rule. The Department received two responsive comments, both in support of eliminating 22 CFR 42.68. The Department is now promulgating a final rule with no changes from the proposed rule. This rule results in no change for applicants, as the authority granted by 22 CFR 42.68 was no longer used by consular officers.1 Analysis of Comments The proposed rule was published in the Federal Register on March 17, 2023. The comment period closed May 16, 2023. The Department received two responsive comments, both in favor of the proposed elimination of 22 CFR 42.68, and one non-responsive comment. One of the two responsive comments advocated for replacing 22 CFR 42.68 with ‘‘supportive and accessible eligibility screenings for noncitizens seeking visas,’’ while the other comment only expressed its support for the proposed elimination. The Department has considered these comments. Considering the complexity required to evaluate a noncitizen’s eligibility for a visa, and limited resources to reliably 1 See PO 00000 the proposed rule for further discussion. Frm 00017 Fmt 4700 Sfmt 4700 assess eligibility absent a visa application, the Department is unable to offer any eligibility screenings. Noncitizens who wish to receive a nonimmigrant or immigrant visa must formally apply for a visa to allow a consular officer to assess their eligibility for the visa. Regulatory Findings A. Administrative Procedure Act As this rule involves amending visa policy, which is a foreign affairs function of the United States, it is exempt from both the delayed effective date and notice and comment requirements of 5 U.S.C. 553 per subsection (a)(1). Notwithstanding the applicability of the foreign affairs exception to this rule, the Department, for its own benefit, sought public comment on the proposed elimination of 22 CFR 42.68. See, e.g., Hoctor v. U.S. Dep’t of Agric., 82 F.3d 165, 171–72 (7th Cir. 1996) (observing that there is nothing in the APA that forbids an agency’s use of notice-and-comment procedures even if not required under the APA, and that courts should attach no weight to an agency’s varied approaches involving similar rules). Though this rule is not subject to 5 U.S.C. 553(d), the Department is also choosing to delay the effective date of this rule for 30 days. B. Regulatory Flexibility Act As this rulemaking is not required to be published for notice and comment under 5 U.S.C. 553, it is exempt from the regulatory flexibility analysis requirements set forth by the Regulatory E:\FR\FM\07DER1.SGM 07DER1

Schedules of Controlled Substances: Placement of Nine Specific 
Fentanyl-Related Substances in Schedule I

AGENCY: Drug Enforcement Administration, Department of Justice.

ACTION: Final rule.

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

SUMMARY: With the issuance of this final rule, the Drug Enforcement 
Administration places nine fentanyl-related substances, as identified 
in this final rule, including their isomers, esters, ethers, salts, and 
salts of isomers, esters, and ethers whenever the existence of such 
isomers, esters, ethers, and salts is possible, in schedule I of the 
Controlled Substances Act. These nine fentanyl-related substances are 
currently listed in schedule I pursuant to a temporary scheduling 
order. This action makes permanent the imposition of the regulatory 
controls and administrative, civil, and criminal sanctions applicable 
to schedule I controlled substances on persons who handle (manufacture, 
distribute, import, export, engage in research, conduct instructional 
activities or chemical analysis with, or possess), or propose to handle 
these nine specific fentanyl-related controlled substances.

DATES: Effective date: December 7, 2023.

FOR FURTHER INFORMATION CONTACT: Dr. Terrence L. Boos, Drug and 
Chemical Evaluation Section, Diversion Control Division, Drug 
Enforcement Administration; Telephone: (571) 362-3249.

SUPPLEMENTARY INFORMATION: In this rule, the Drug Enforcement 
Administration (DEA) is permanently scheduling the following nine 
controlled substances including their isomers, esters, ethers, salts, 
and salts of isomers, esters, and ethers whenever the existence of such 
isomers, esters, ethers, and salts is possible, in schedule I of the 
Controlled Substances Act (CSA):
     meta-fluorofentanyl (N-(3-fluorophenyl)-N-(1-
phenethylpiperidin-4-yl)propionamide),
     meta-fluoroisobutyryl fentanyl (N-(3-fluorophenyl)-N-(1-
phenethylpiperidin-4-yl)isobutyramide),
     para-methoxyfuranyl fentanyl (N-(4-methoxyphenyl)-N-(1-
phenethylpiperidin-4-yl)furan-2-carboxamide),
     3-furanyl fentanyl (N-(1-phenethylpiperidin-4-yl)-N-
phenylfuran-3-carboxamide),
     2',5'-dimethoxyfentanyl (N-(1-(2,5-
dimethoxyphenethyl)piperidin-4-yl)-N-phenylpropionamide),
     isovaleryl fentanyl (3-methyl-N-(1-phenethylpiperidin-4-
yl)-N-phenylbutanamide),
     ortho-fluorofuranyl fentanyl (N-(2-fluorophenyl)-N-(1-
phenethylpiperidin-4-yl)furan-2-carboxamide),
     alpha'-methyl butyryl fentanyl (2-methyl-N-(1-
phenethylpiperidin-4-yl)-N-phenylbutanamide), and
     para-methylcyclopropyl fentanyl (N-(4-methylphenyl)-N-(1-
phenethylpiperidin-4-yl)cyclopropanecarboxamide).

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 (1) on his own motion; (2) at the 
request of the Secretary of the Department of Health and Human Services 
(HHS); \1\ or (3) on the petition of any interested party.\2\ This 
action was initiated on the Attorney General's own motion, as delegated 
to the Administrator of the DEA (Administrator), and is supported by, 
inter alia, a recommendation from the Assistant Secretary for Health of 
HHS

[[Page 85105]]

(Assistant Secretary) and an evaluation of all relevant data by DEA. 
This action continues the imposition of the regulatory controls and 
administrative, civil, and criminal sanctions of schedule I controlled 
substances on any person who handles or proposes to handle meta-
fluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl 
fentanyl, 3-furanyl fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl 
fentanyl, ortho-fluorofuranyl fentanyl, alpha'-methyl butyryl fentanyl, 
and para-methylcyclopropyl fentanyl.
---------------------------------------------------------------------------

    \1\ As discussed in a memorandum of understanding entered into 
by the Food and Drug Administration (FDA) and the National Institute 
on Drug Abuse (NIDA), FDA acts as the lead agency within HHS in 
carrying out the Secretary's scheduling responsibilities under the 
CSA, with the concurrence of NIDA. 50 FR 9518, Mar. 8, 1985. The 
Secretary of HHS has delegated to the Assistant Secretary for Health 
of HHS the authority to make domestic drug scheduling 
recommendations. 58 FR 35460, July 1, 1993.
    \2\ 21 U.S.C. 811(a).
---------------------------------------------------------------------------

Background

    On February 6, 2018, DEA published an order in the Federal Register 
(FR) (83 FR 5188) amending 21 CFR 1308.11(h), temporarily placing 
fentanyl-related substances, as defined in that order, in schedule I of 
the CSA based upon a finding that these substances pose an imminent 
hazard to the public safety and pursuant to the temporary scheduling 
provisions of 21 U.S.C. 811(h). The nine substances named in this final 
rule meet the existing definition of fentanyl-related substances, as 
they are not otherwise controlled in any other schedule (i.e., not 
included under another DEA Controlled Substance Code Number) and are 
structurally related to fentanyl by one or more of the five 
modifications listed under the definition. That temporary scheduling 
order was effective on the date of publication and was based on 
findings by the former Acting Administrator that the temporary 
scheduling of these substances was necessary to avoid an imminent 
hazard to the public safety pursuant to 21 U.S.C. 811(h)(1). Pursuant 
to 21 U.S.C. 811(h)(2), the temporary control of fentanyl-related 
substances, a class of substances as defined in the order, as well as 
these nine specific substances already covered by that order, was set 
to expire on February 6, 2020. However, on February 6, 2020, as 
explained in DEA's April 10, 2020, correcting amendment (85 FR 20155), 
Congress extended that expiration date until May 6, 2021, by enacting 
the Temporary Reauthorization and Study of the Emergency Scheduling of 
Fentanyl Analogues Act (Pub. L. 116-114, sec. 2, 134 Stat. 103). This 
temporary order was subsequently extended multiple times, most recently 
on December 29, 2022, through the Consolidated Appropriations Act, 
2023, which extended the order until December 31, 2024.
    Comment: One commenter stated that fentanyl and the list of related 
substances is a hazard due to the overdose deaths that have been 
occurring. This commenter also referenced the National Institute on 
Drug Abuse, stating that fentanyl-related overdoses have been 
increasing in the United States. Lastly, this commenter stated that 
permanently placing fentanyl and the list of related substances in 
schedule I would improve public health and allow for regulation of 
these substances.
    DEA Response: DEA appreciates the comments in support of this 
rulemaking. One clarification to note is that fentanyl remains a 
schedule II substance. This final rule only applies to the fentanyl-
related substances that are listed in this final order.
    Comment: One commenter stated the proposed rule would make it more 
difficult to produce and distribute these dangerous fentanyl-related 
substances, which would help combat the opioid epidemic in the United 
States. This commenter also referenced a news article by National 
Public Radio, stating that these nine fentanyl-related substances are 
not currently classified as controlled substances, making it easy to 
produce and distribute these substances without legal consequences. 
Lastly, this commenter recognized that this proposal could have 
significant impacts on the healthcare industry, such as increased 
oversight and regulation of fentanyl-related substances, which could 
prevent their misuse and abuse.
    DEA Response: DEA appreciates the comments in support of this 
rulemaking. One clarification to note based on the comment above is 
that, by temporary order on February 6, 2018, DEA placed these nine 
fentanyl-related substances under schedule I. 83 FR 5188. That 
temporary order defined a fentanyl-related substance to mean any 
substance not otherwise controlled in any schedule (i.e., not listed 
under another DEA Controlled Substance Code Number), and for which no 
exemption or approval is in effect under section 505 of the Federal 
Food, Drug, and Cosmetic Act (21 U.S.C. 355), that is structurally 
related to fentanyl by one or more of five specified structural 
modifications. Therefore, these nine fentanyl-related substances are in 
fact already schedule I controlled substances.
    The final rule being issued today applies to nine fentanyl-related 
substances that were the subject of a February 6, 2018, temporary 
scheduling order. These nine substances will now be listed in 21 CFR 
1308.11(b), as specified in the text of the rule that appears below. 
This final rule should not have a significant impact on the healthcare 
industry because these nine fentanyl-related substances have no medical 
use and they have already been added as schedule I controlled 
substances since 2018.
    Comment: One commenter discussed the direct and indirect effects on 
federal and state healthcare from this regulation. The commenter 
suggested that this regulation will boost federal oversight of 
manufacturing and disseminating harmful chemicals. In addition, this 
regulation would limit availability and expected use, ensure protection 
of residents, and increases confidence in the medical field. In 
addition, the commenter stated that is critical to restrict the use of 
``fentanyl replicates'' to those who may need them for medical 
conditions. Lastly, the commenter stated that raising awareness of the 
risks of abusing these drugs benefits their prevention.
    DEA Response: DEA appreciates the comments in support of this 
rulemaking. As mentioned previously, FDA has not approved a marketing 
application for a drug product containing any of these nine substances 
for any therapeutic indication. These substances have no medical use in 
the United States.
    Comment: One commenter stated that this rule will affect federal 
healthcare because many federal agencies are trying to tackle the 
opioid crisis. The commenter discussed the rising number of pediatric 
deaths from fentanyl in 2021 and the surge in 2018 of fentanyl 
overdoses among older adolescents as well as in children younger than 
five. The commenter agrees with this final rule to schedule these 
fentanyl-related substances. The commenter also stated that fentanyl is 
highly addictive and that while fentanyl is prescribed for chronic pain 
or major surgery, it should be a last resort.
    DEA Response: DEA appreciates the comments in support of this 
rulemaking.
    Comment: One commenter agreed with this final rule to make 
permanent these nine specific fentanyl-related substances rather than 
continuing multiple temporary extensions. Once finalized, the commenter 
stated that the federal government could act against anyone handling 
these substances since over 150 people die each day from a fentanyl-
related drug overdose.
    DEA Response: DEA appreciates the comments in support of this 
rulemaking. Again, DEA notes that fentanyl is a schedule II controlled 
substance that can be prescribed for approved medical uses. However, 
the nine fentanyl-related substances addressed in this rule are already

[[Page 85106]]

schedule I controlled substances and none of them have any medical use 
in the United States.
    Comment: One commenter stated that fentanyl should be placed in 
schedule I. The commenter compared this substance to marijuana, which 
is a schedule I drug and thought it was mind-blowing that fentanyl was 
not a schedule I substance. It was suggested that the rising number of 
deaths, the risk to public health, abuse potential, and dependency 
should classify fentanyl as a schedule I.
    DEA Response: DEA appreciates this comment. As stated previously, 
fentanyl remains a schedule II substance. Fentanyl has approved medical 
uses in the United States. This final rule only applies to the 
fentanyl-related substances that are listed in this final order.

Scheduling Conclusion

    After consideration of the relevant matter presented through public 
comments, the scientific and medical evaluation and accompanying 
recommendation of HHS, and after its own eight-factor evaluation, DEA 
finds that these facts and all other relevant data constitute 
substantial evidence of the potential for abuse of meta-fluorofentanyl, 
meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl 
fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl fentanyl, ortho-
fluorofuranyl fentanyl, alpha'-methyl butyryl fentanyl, and para-
methylcyclopropyl fentanyl. DEA is permanently scheduling these nine 
fentanyl-related substances as schedule I controlled substances under 
the CSA.

Determination of Appropriate Schedule

    The CSA establishes five schedules of controlled substances known 
as schedules I, II, III, IV, and V. The CSA also specifies the findings 
required to place a drug or other substance in any particular 
schedule.\3\ After consideration of the analysis and recommendation of 
the Assistant Secretary for HHS and review of all other available data, 
the Administrator, pursuant to 21 U.S.C. 811(a) and 812(b)(1), finds 
the following:
---------------------------------------------------------------------------

    \3\ 21 U.S.C. 812(b).
---------------------------------------------------------------------------

    (1) The abuse potential of meta-fluorofentanyl, meta-
fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl 
fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl fentanyl, ortho-
fluorofuranyl fentanyl, alpha'-methyl butyryl fentanyl, and para-
methylcyclopropyl fentanyl is associated with each substance's 
pharmacological similarity to other schedule I and II mu-opioid 
receptor agonist substances which have a high potential for abuse. 
Similar to morphine (schedule II), fentanyl (schedule II), and several 
schedule I opioid substances that are structurally related to fentanyl, 
these nine fentanyl-related substances have been shown to bind and act 
as mu-opioid receptor agonists;
    (2) meta-Fluorofentanyl, meta-fluoroisobutyryl fentanyl, para-
methoxyfuranyl fentanyl, 3-furanyl fentanyl, 2',5'-dimethoxyfentanyl, 
isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, alpha'-methyl 
butyryl fentanyl, and para-methylcyclopropyl fentanyl, have no 
currently accepted medical use in treatment in the United States; \4\ 
and
---------------------------------------------------------------------------

    \4\ Although there is no evidence suggesting that meta-
fluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl 
fentanyl, 3-furanyl fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl 
fentanyl, ortho-fluorofuranyl fentanyl, alpha'-methyl butyryl 
fentanyl, and para-methylcyclopropyl fentanyl have a currently 
accepted medical use in treatment in the United States, it bears 
noting that a drug cannot be found to have such medical use unless 
DEA concludes that it satisfies a five-part test. Specifically, with 
respect to a drug that has not been approved by FDA, to have a 
currently accepted medical use in treatment in the United States, 
all of the following must be demonstrated:
    i. The drug's chemistry must be known and reproducible;
    ii. there must be adequate safety studies;
    iii. there must be adequate and well-controlled studies proving 
efficacy;
    iv. the drug must be accepted by qualified experts; and
    v. the scientific evidence must be widely available.
    57 FR 10499 (1992).
---------------------------------------------------------------------------

    (3) There is a lack of accepted safety for use of meta-
fluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl 
fentanyl, 3-furanyl fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl 
fentanyl, ortho-fluorofuranyl fentanyl, alpha'-methyl butyryl fentanyl, 
and para-methylcyclopropyl fentanyl under medical supervision.
    Based on these findings, the Administrator concludes that meta-
fluorofentanyl, meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl 
fentanyl, 3-furanyl fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl 
fentanyl, ortho-fluorofuranyl fentanyl, alpha'-methyl butyryl fentanyl, 
and para-methylcyclopropyl fentanyl, including their isomers, esters, 
ethers, salts, and salts of isomers, esters, and ethers whenever the 
existence of such isomers, esters, ethers, and salts is possible, 
warrant control in schedule I of the CSA.\5\
---------------------------------------------------------------------------

    \5\ 21 U.S.C. 812(b)(1).
---------------------------------------------------------------------------

    This final rule does not affect the scheduling of fentanyl itself, 
which remains a schedule II controlled substance.

Regulatory Analyses

Executive Orders (E.O.) 12866 (Regulatory Planning and Review), 13563 
(Improving Regulation and Regulatory Review), and 14094 (Modernizing 
Regulatory Review)

    This action is not a significant regulatory action as defined by 
Executive Order (E.O.) 12866 (Regulatory Planning and Review), section 
3(f), and the principles reaffirmed in E.O. 13563 (Improving Regulation 
and Regulatory Review); and, accordingly, this action has not been 
reviewed by the Office of Management and Budget (OMB). This action 
makes no change in the status quo, as meta-fluorofentanyl, meta-
fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl 
fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl fentanyl, ortho-
fluorofuranyl fentanyl, alpha'-methyl butyryl fentanyl, and para-
methylcyclopropyl fentanyl are already listed as a schedule I 
controlled substances.

Executive Order 12988, Civil Justice Reform

    This action 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 rulemaking does not have federalism implications warranting 
the application of E.O. 13132. The 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 rule does not have tribal implications warranting the 
application of E.O. 13175. It does not have substantial direct effects 
on one or more Indian tribes, on the relationship between the Federal 
Government and Indian tribes, or on the distribution of power and 
responsibilities between the Federal Government and Indian tribes.

Regulatory Flexibility Act

    The Administrator, in accordance with the Regulatory Flexibility 
Act, 5 U.S.C. 601-602, has reviewed this final rule and, by approving 
it, certifies that it will not have a significant economic impact on a 
substantial number of small

[[Page 85108]]

entities. On February 6, 2018, DEA published an order to temporarily 
place fentanyl-related substances 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 meta-fluorofentanyl, 
meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl 
fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl fentanyl, ortho-
fluorofuranyl fentanyl, alpha'-methyl butyryl fentanyl, and para-
methylcyclopropyl fentanyl have already established and implemented the 
systems and processes required to handle these substances.
    As discussed in the NPRM, there are 108 registrations authorized to 
handle one or more of the following substances: meta-fluorofentanyl, 
meta-fluoroisobutyryl fentanyl, para-methoxyfuranyl fentanyl, 3-furanyl 
fentanyl, 2',5'-dimethoxyfentanyl, isovaleryl fentanyl, ortho-
fluorofuranyl fentanyl, alpha'-methyl butyryl fentanyl, and para-
methylcyclopropyl fentanyl, as well as a number of registered 
analytical labs that are authorized to handle schedule I controlled 
substances generally. These 108 registrations represent a maximum of 95 
small entities. Therefore, DEA conservatively estimates as many as 95 
small entities are affected by this rule.
    A review of the 108 registrations indicates that all entities that 
currently handle meta-fluorofentanyl, meta-fluoroisobutyryl fentanyl, 
para-methoxyfuranyl fentanyl, 3-furanyl fentanyl, 2',5'-
dimethoxyfentanyl, isovaleryl fentanyl, ortho-fluorofuranyl fentanyl, 
alpha'-methyl butyryl fentanyl, and para-methylcyclopropyl fentanyl, 
also handle other schedule I controlled substances and have established 
and implemented (or maintain) the systems and processes required to 
handle these substances. Therefore, DEA anticipates that this final 
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 small entities. Therefore, DEA has concluded that this final 
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 
action would not result in any federal mandate that may result ``in the 
expenditure by State, local, and Tribal Governments, in the aggregate, 
or by the private sector, of $100 million or more (adjusted annually 
for inflation) in any 1 year * * * .'' Therefore, neither a Small 
Government Agency Plan nor any other action is required under UMRA of 
1995.

Paperwork Reduction Act of 1995

    This final rule does not impose a new collection or modify an 
existing collection of information under the Paperwork Reduction Act of 
1995. 44 U.S.C. 3501-3521. Also, this final rule does not impose new or 
modify existing recordkeeping or reporting requirements on State or 
local governments, individuals, businesses, or organizations. However, 
this final rule does require compliance with the following existing OMB 
collections: 1117-0003, 1117-0004, 1117-0006, 1117-0008, 1117-0009, 
1117-0010, 1117-0012, 1117-0014, 1117-0021, 1117-0023, 1117-0029, and 
1117-0056. 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.

Congressional Review Act

    This rule is not a major rule as defined by the Congressional 
Review Act (CRA), 5 U.S.C. 804. Pursuant to the CRA, DEA is submitting 
a copy of this final rule to both Houses of Congress and to the 
Comptroller General.

Determination To Make Rule Effective Immediately

    As indicated above, this rule finalizes the schedule I control 
status of nine substances that has already been in effect. These nine 
substances all fall within the definition of fentanyl-related 
substances set forth in the February 6, 2018, temporary scheduling 
order (83 FR 5188). Through the Temporary Reauthorization and Study of 
the Emergency Scheduling of Fentanyl Analogues Act, which became law on 
February 6, 2020, Congress extended the temporary control of fentanyl-
related substances until May 6, 2021. This temporary order was 
subsequently extended multiple times, most recently on December 29, 
2022, through the Consolidated Appropriations Act, 2023, which extended 
the order until December 31, 2024.\7\ The February 2018 order was 
effective on the date of publication, and was based on findings by the 
then-Acting Administrator that the temporary scheduling of the 
fentanyl-related substances was necessary to avoid an imminent hazard 
to the public safety pursuant to 21 U.S.C. 811(h)(1). Because this rule 
finalizes the control status of nine substances that has already been 
in effect, it does not alter the legal obligations of any person who 
handles these substances. Rather, it merely makes permanent the current 
scheduling status and corresponding legal obligations. Therefore, since 
this rule does not change the current scheduling status and 
corresponding legal obligations, DEA is making the rule effective on 
the date of publication in the Federal Register, as any delay in the 
effective date is unnecessary and would be contrary to the public 
interest.
