Schedules of Controlled Substances: Temporary Placement of 2-Fluorodeschloroketamine in Schedule I

Official abstract: The Drug Enforcement Administration (DEA) issues this temporary order to schedule 2-(2-fluorophenyl)-2- (methylamino)cyclohexan-1-one (commonly known as 2- fluorodeschloroketamine or 2-FDCK), including its salts, isomers, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible within the specific chemical designation, in schedule I of the Controlled Substances Act. DEA bases this action on a finding that placing 2-fluorodeschloroketamine in schedule I is necessary to avoid an imminent hazard to public safety. This order imposes the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle this substance.
