Which agency enforces the Controlled Substances Act?

• A. FDA
• B. Diversion
• C. Drug Enforcement Administration (DEA)
• D. Medical Director

Answer: (C)

The main idea is that enforcement of the Controlled Substances Act is carried out by a federal agency specifically dedicated to drug enforcement. The Drug Enforcement Administration (DEA) sits under the Department of Justice and is responsible for investigating illegal drug trafficking, preventing diversion of controlled substances from legitimate sources, and enforcing rules about how these substances are manufactured, distributed, and dispensed. This includes overseeing compliance across manufacturers, wholesalers, clinics, and pharmacies, and coordinating with other agencies when scheduling decisions or law enforcement actions are needed.

The FDA plays a crucial regulatory role in approving drugs and setting labeling and safety standards, but it does not enforce the Controlled Substances Act. Diversion is not an agency, and a Medical Director is a clinical leadership position, not a federal enforcement body. Scheduling decisions for controlled substances involve collaboration between the DEA and the Department of Health and Human Services, but the enforcement function itself is the DEA’s responsibility.
