The United States Drug Enforcement Agency (DEA) requires that UCSF research labs submit an inventory of DEA Controlled Substances every two years.

The DEA requires that this inventory be submitted on a specific date and time. The specific inventory date will be announced by EH&S. All researchers must submit an on-hand physical inventory for controlled substances present in their lab. You must examine your Controlled Substances inventory, confirm on-hand stock, and submit the inventory via RIO.

Please be sure to file a hard copy of your inventory with your controlled substances records. Failure to comply with this DEA requirement may result in the Campus Procurement & Contracting Department suspending orders for Controlled Substances and termination of Controlled Substances Authorization (CSA).

If you are unfamiliar with online inventory submissions, please contact your Department Safety Advisor (DSA) for assistance.
