The Drug Enforcement Administration (DEA) is the primary federal agency responsible for enforcing the controlled substances laws and regulations of the United States. Established in 1973, the DEA focuses specifically on combating drug trafficking and abuse, which includes investigating and prosecuting drug offenses, regulating the manufacturing and distribution of controlled substances, and coordinating international drug enforcement efforts.

The DEA's role is crucial in addressing the complex issues surrounding drug-related crime and public health, making it the leading agency in this area. It also collaborates with other federal, state, local, and international law enforcement agencies to share intelligence and resources, enhancing the effectiveness of drug enforcement efforts across jurisdictions.

While the FBI, DHS, and Secret Service may have roles involving drug enforcement as part of their broader missions, these agencies do not specialize in drug law enforcement to the same extent as the DEA. The FBI addresses a wide array of criminal activities, DHS focuses on homeland security, including immigration and border protection, and the Secret Service is primarily concerned with protecting the president and investigating financial crimes. Thus, the specialized mandate and operations of the DEA establish it as the foremost agency in drug enforcement.
