How often must a DEA registrant take a complete inventory of all controlled substances on hand?

Giải thích

Federal law requires a biennial inventory, meaning a complete count of controlled substances on hand at least every 2 years, in addition to the initial inventory taken when the registrant begins handling controlled substances. Annual, semiannual, and five-year cycles are not the federal standard, although some states require inventories more often. Schedule II records must be kept separate from all other records and all controlled substance records must be readily retrievable and kept at least 2 years; this is a federal minimum and some states are stricter.
