How often must a complete inventory of all controlled substances be conducted?

• A. Every year
• B. Every 2 years (biannually)
• C. Every 3 years
• D. Every 5 years

Answer: (B)

A complete inventory of all controlled substances must be conducted biennially. The DEA requires a full, accurate count of every controlled substance on hand at the registered location at least once every two years, covering all schedules (I through V). This snapshot of stock creates a paper trail to verify accountability, helps detect diversion, and ensures records align with purchases, dispositions, and serial numbers. The inventory date is recorded and the records must be kept for a minimum of two years from that date, ready for inspection.
