If a controlled substance is stolen or lost, which DEA form must be used to report it?

• A. DEA Form 106
• B. DEA Form 41
• C. DEA Form 222
• D. DEA Form 510

Answer: (A)

The main idea is knowing how to report a theft or loss of controlled substances to the DEA. The form designed for this purpose is the one used to file a Report of Theft or Loss of Controlled Substances. It is specifically built to capture all the details needed by the DEA, such as what was stolen, how much, the exact substance (name, form, strength), where and when the loss was discovered, the circumstances of the incident, and any police or other incident numbers. Submitting this form promptly is required to keep federal regulators informed and to help protect public safety.

This form is the best choice because it targets theft or loss directly and ensures the regulator has the complete information needed to start any necessary investigations or follow-up actions. The other forms serve different purposes—destruction or disposal of controlled substances, ordering Schedule I or II substances, or registration-related tasks—and are not appropriate for reporting a theft or loss.
