Five designer benzodiazepines now Schedule I
Starting April 1, 2026, clonazolam, diclazepam, etizolam, flualprazolam, and flubromazolam (and their salts/isomers) are permanently placed in Schedule I of the Controlled Substances Act. That means these substances are legally treated as having high abuse potential, no accepted medical use in the United States, and are subject to Schedule I controls.
Unauthorized possession and handling unlawful
Possession or handling of clonazolam, diclazepam, etizolam, flualprazolam, or flubromazolam in any manner not authorized by the CSA is unlawful as of April 1, 2026, and may subject the person to administrative, civil, and/or criminal sanctions. Retail sales to the general public of Schedule I substances are not allowed under the CSA.
Registration required to handle these drugs
Any person who handles (manufactures, distributes, imports/exports, engages in research, conducts instructional activities or chemical analysis with, or possesses) these five substances must be registered with DEA under 21 U.S.C. 822, 823, 957, and 958 and comply with 21 CFR parts 1301 and 1312. Anyone currently handling these substances who is not registered must submit a registration application and may not continue to handle them unless DEA approves the application.
Research allowed but requires DEA permission
Placement in Schedule I does not preclude academic or scientific research, but anyone who wishes to conduct research on clonazolam, diclazepam, etizolam, flualprazolam, or flubromazolam must seek and obtain DEA permission and appropriate registration before handling them.
Schedule I regulatory controls apply (security, records)
As Schedule I substances, clonazolam, diclazepam, etizolam, flualprazolam, and flubromazolam must be handled under Schedule I security requirements, labeling and packaging rules, quotas for manufacture, biennial inventories, recordkeeping and reporting, DEA order-form requirements, and import/export controls per the CSA and implementing CFR parts (e.g., 21 CFR parts 1301, 1302, 1303, 1304, 1312, and 1317).
Surrender or transfer of existing stocks before effective date
Any person unwilling or unable to obtain a Schedule I registration must surrender or transfer all quantities of these five substances to a DEA-registered person before the effective date of the final scheduling action, and any disposal must follow 21 CFR part 1317 and applicable laws. The effective date for the permanent scheduling is April 1, 2026.
