How often must the controlled substance inventory list be updated?

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

Answer: (B)

Regular verification of controlled substances is required to keep accurate records and prevent loss or diversion. This verification is done as a biennial inventory—every two years. On a designated date, you perform a physical count of all Schedule I and II substances and reconcile that count with the records, updating the inventory to reflect any additions, disposals, or discrepancies since the last inventory. This interval balances ensuring accountability with avoiding excessive administrative burden. More frequent inventories would exceed what regulations require, while longer intervals would allow discrepancies to go undetected.
