The Administrator of the Drug Enforcement Administration is issuing this notice of intent to publish a 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.
