Which U.S. agency is responsible for regulations related to controlled substances?

The U.S. Drug Enforcement Administration (DEA) is the primary agency responsible for enforcing the controlled substances laws and regulations. This agency plays a crucial role in combating drug trafficking and abuse, as well as regulating the manufacture, distribution, and dispensation of controlled substances in the United States. It oversees the enforcement of the Controlled Substances Act, ensuring that both legitimate medical and scientific uses of these substances are protected while preventing illegal activities.

The DEA conducts investigations, coordinates with other law enforcement agencies, and administers drug enforcement programs. Its focus on controlled substances distinguishes it from other federal agencies that may deal with different regulatory areas, such as alcohol and tobacco, aviation safety, or transportation safety. Each of these agencies has distinct missions that do not overlap with the specific responsibilities of the DEA in relation to controlled substances.
