Specific Listing for Hexahydrocannabinol, A Currently Controlled Schedule I Substance

Document 2026-08595 is a Final Rule published by the Department of Justice in the Federal Register on May 4, 2026, with an effective date of May 4, 2026. The Drug Enforcement Administration (DEA) is establishing a specific listing and DEA Controlled Substances Code Number (drug code) for 6,6,9-trimethyl-3-pentyl-6a,7,8,9,10,10a-hexahydro-6H- benzo[c]chromen-1-ol (also known as hexahydrocannabinol, and HHC) in schedule I of the Controlled Substances Act (CSA). Although hexahydrocannabinol 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 under drug code 7370 because it meets the definition of tetrahydrocannabinols, a schedule I hallucinogen. Therefore, DEA is simply amending the schedule I hallucinogenic substances list to separately include hexahydrocannabinol.
