Specific Listing for 4F-MDMB-BINACA, a Currently Controlled Schedule I Substance

The Drug Enforcement Administration is establishing a specific listing and Administration Controlled Substances Code Number (drug code) for 4F-MDMB-BINACA (also known as 4F-MDMB-BUTINACA or methyl 2- (1-(4-fluorobutyl)-1H-indazole-3-carboxamido)-3,3-dimethylbutanoate) in schedule I of the Controlled Substances Act (CSA). Although 4F-MDMB- BINACA is not specifically listed in schedule I of the CSA with its own unique drug code, it has been controlled in the United States since April 2017 as a positional isomer of 5F-AMB, a schedule I hallucinogen. Therefore, DEA is simply amending the schedule I hallucinogenic substances list in its regulations to separately include 4F-MDMB- BINACA.
