Which DEA form is used to report lost or stolen controlled substances?

The correct choice for reporting lost or stolen controlled substances is DEA Form 106. This form is specifically designed for registrants to report the theft or significant loss of controlled substances to the Drug Enforcement Administration (DEA). The requirement to report such incidents is critical for maintaining the security and accountability of controlled substances, which are strictly regulated due to their potential for abuse and the dangers they pose to public health.

When a registrant discovers that controlled substances are missing, they must complete the DEA Form 106 and send it to the DEA promptly. This form requires details regarding the circumstances of the loss or theft, including the type and quantity of the controlled substances involved. This process helps law enforcement track potential drug diversion and hold involved parties accountable.

The other form options do not serve this specific purpose. For example, DEA Form 104 is used for applications to register as a manufacturer under the Controlled Substances Act, while Form 105 is related to the registration of an exports/imports of controlled substances. DEA Form 107 addresses the disposal of controlled substances rather than reporting theft or loss. Therefore, the specificity of DEA Form 106 in addressing the issue of lost or stolen controlled substances makes it the correct answer.
