Schedules of Controlled Substances: Extension of Temporary Placement of Seven Specific Fentanyl-Related Substances in Schedule I of the Controlled Substances Act

The Administrator of the Drug Enforcement Administration is issuing this temporary scheduling order to extend the temporary schedule I status of seven specific fentanyl-related substances, as identified in this order, including their isomers, esters, ethers, salts, and salts of isomers, esters and ethers. These seven substances fall within the definition of fentanyl-related substances set forth in the February 6, 2018, temporary scheduling order. Through the Temporary Reauthorization and Study of 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. This temporary order will extend the temporary scheduling of seven specific fentanyl-related substances for one year, or until the permanent scheduling action for these substances is completed, whichever occurs first.
