Imports of Synthetic Opioid Restricted
The Drug Enforcement Administration has issued a final order that temporarily schedules the synthetic opioid N-(4-fluorophenyl)-N-(1-phenethylpiperidin-4-yl)isobutyramide (4-fluoroisobutyryl fentanyl or para-fluoroisobutyryl fentanyl) and its isomers, esters, ethers, salts and salts of isomers, esters and ethers into schedule I pursuant to the temporary scheduling provisions of the Controlled Substances Act. As a result, this substance is subject to the regulatory controls and administrative, civil and criminal sanctions applicable to the manufacture, distribution, reverse distribution, possession, importation, exportation, research and conduct of instructional activities and chemical analysis of schedule I controlled substances. This order became effective on 23 March and will be in effect for two years, with a possible extension of one year, pending completion of the permanent scheduling process.
According to the DEA, available data and information indicate that 4-fluoroisobutyryl fentanyl has 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.
