Permanent Schedule I: Criminal Penalties
The DEA proposes to permanently place 4F-MDMB-BUTICA, ADB-4en-PINACA, 5F-EDMB-PICA, and MMB-FUBICA in Schedule I. If finalized, anyone who manufactures, distributes, imports, exports, possesses, or uses these drugs would be subject to the CSA's schedule I administrative, civil, and criminal sanctions.
Registrants Face Schedule I Compliance Rules
If these four substances are permanently scheduled, manufacturers, distributors, importers, exporters, and researchers handling them must register with DEA and comply with Schedule I rules for security, labeling, quotas, inventories, records and reports, order forms, and import/export requirements. DEA identified 11 suppliers of these substances (expects 10 affected) and states most entities already implemented required systems; DEA certified the rule will not have a significant economic impact on a substantial number of small entities.
