Which organization is primarily concerned with drug enforcement among U.S. agents overseas?

The Drug Enforcement Administration (DEA) is primarily concerned with drug enforcement among U.S. agents overseas. The DEA's mission is to enforce the controlled substances laws and regulations of the United States and to target the organizations involved in the illegal drug trade. This includes a focus on disrupting drug trafficking operations not only within the U.S. but also in other countries where these organizations operate.

The DEA works closely with international law enforcement agencies and other countries' drug enforcement units to combat drug trafficking and its associated crimes. Their presence overseas allows them to gather intelligence, establish cooperative agreements, and conduct joint operations aimed at dismantling drug trafficking networks that operate across borders. This specialized role differentiates the DEA from other agencies such as the FBI, Customs and Border Protection (CBP), and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), which have broader or different enforcement responsibilities that do not focus exclusively on drug-related crimes internationally.
