Specific Listing for 3-Chloromethcathinone, A Currently Controlled Schedule I Substance

The Drug Enforcement Administration (DEA) is establishing a specific listing and DEA Controlled Substances Code Number (drug code) for 1-(3-chlorophenyl)-2-(methylamino)propan-1-one (3- chloromethcathinone; 3-CMC) in schedule I of the Controlled Substances Act (CSA). Although 3-chloromethcathinone is not specifically listed in schedule I of the CSA with its own unique drug code, it is a schedule I controlled substances in the United States because it is a positional isomer of 4-chloromethcathinone, which is a schedule I hallucinogen. Therefore, DEA is simply amending the schedule I hallucinogenic substances list in its regulations to separately include 3- chloromethcathinone.
