The U.S. Drug Enforcement Agency is responsible for enforcing U.S. laws regarding controlled substances. This entails conducting criminal investigations into suspected drug traffickers and gangs that traffic controlled substances. The DEA also implements drug education and prevention programs designed to discourage people from using substances in an illegal or recreational manner by informing them of the significant dangers of doing so. If you become a DEA agent, it’s quite likely that no two days will look the same. You can expect to work closely with other federal, state and local agencies, as well as foreign entities in an attempt to identify and apprehend individuals and criminal organizations engaged in drug trafficking. Ultimately, DEA agents strive to apprehend suspects and confiscate controlled substances before they can reach the hands of potential users. In doing so, DEA agents may sometimes need to go undercover.
