I. The U.S. Drug Enforcement Administration (DEA) issued a final rule creating a 
specific listing for 1-(1,3-benzodioxol-5-yl)-2-(dimethylamino)pentan-1-one (other 
names: dipentylone, N,N-dimethylpentylone), 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 within the specific chemical 
designation, in schedule I of the Controlled Substances Act (CSA) effective August 
8, 2025. This final rule was published in the Federal Register, Volume 90, Number 
151, pages 38396-38398. 
Dipentylone is already a controlled substance in the United States under schedule I, 
as it is a positional isomer of the schedule I hallucinogen N-ethylpentylone. This 
scheduling action creates a specific listing for dipentylone. 
II. The DEA issued a temporary order placing 
2-(4-methoxybenzyl)-5-nitro-1-(2-(pyrrolidin-1-yl)ethyl)-1H-benzimidazole 
(commonly known as, N-pyrrolidinometonitazene or metonitazepyne) and 5-nitro­
2-(4-propoxybenzyl)-1-(2-(pyrrolidin-1-yl)ethyl)-1H-benzimidazole (commonly 
known as, N-pyrrolidino protonitazene or protonitazepyne), 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 
CSA effective August 15, 2025. This final rule was published in the Federal Register, 
Volume 90, Number 156, pages 39314-39319. 
This scheduling action was taken to avoid an imminent hazard to public safety and 
pursuant to N-pyrrolidino metonitazene and N-pyrrolidino protonitazene having: 
 
a high potential for abuse; 
 
no currently accepted medical use in treatment in the United States; and 
 
a lack of accepted safety for use under medical supervision. 
III. The DEA issued a temporary order extending the temporary schedule I status of 
seven specific fentanyl-related substances effective December 31, 2024. This 
temporary scheduling order was published in the Federal Register, Volume 89, 
Number 249, pages 106311-106315. The order extends the temporary scheduling

 
beta-methylacetyl fentanyl (N-phenyl-N-(1-(2-phenylpropyl)piperidin-4­

 
tetrahydrothiofuranyl fentanyl (N-(1-phenethylpiperidin-4-yl)-N­
phenyltetrahydrothiophene-2-carboxamide; other name: 
tetrahydrothiophene fentanyl). 
The DEA issued a final rule permanently placing these seven specific fentanyl­
related substances, including their isomers, esters, ethers, salts, and salts of 
isomers, esters, and ethers, in schedule I of the CSA effective September 18, 2025. 
This final rule was published in the Federal Register, Volume 90, Number 179, 
pages 44979-44984. 
This scheduling action was taken pursuant to beta-methylacetyl fentanyl, meta­
fluorofuranyl fentanyl, ortho-chlorofentanyl, ortho-methylcyclopropyl fentanyl, 
para-chlorofentanyl, para-fluoro valeryl fentanyl, and tetrahydrothiofuranyl fentanyl 
having: 
 
a high potential for abuse due to their analgesic effects that are mediated by 
mu-opioid receptor agonism; 
 
no currently accepted medical use in treatment in the United States; and 
 
a lack of accepted safety for use under medical supervision. 
IV. The DEA issued a temporary order extending the temporary schedule I status of 
five designer benzodiazepines effective July 26, 2025. This temporary scheduling
