Since it was established through an Executive Order in 1973 as part of the "global war on the drug menace," the Drug Enforcement Administration (DEA) has been tasked with enforcing controlled substance laws and regulations in the United States. It also works with U.S. and international bodies to combat illicit growing, manufacture, and distribution of controlled substances.  It also recommends and supports  non-enforcement programs designed to reduce the availability of illicit controlled substances on domestic and international markets.
