Its primary mission is to combat the illegal drug trade and reduce the supply and demand for illicit drugs in the United States. The DEA works closely with other federal, state, and local agencies to investigate and prosecute drug-related crimes, as well as to disrupt and dismantle drug trafficking organizations. Through its efforts, the DEA aims to protect the health and safety of American citizens and communities from the devastating effects of drug abuse.
