The Diversion Investigator position is a core series position within the DEA. Diversion Investigators enforce the Controlled Substances Act (CSA) and the Chemical Diversion and Trafficking Act (CDTA) regarding the manufacture, distribution and dispensing of legally produced controlled substances and listed chemicals in order to prevent diversion of controlled substances and listed chemicals into the illicit market, while ensuring an adequate, uninterrupted supply of pharmaceutical controlled substances and listed chemicals to meet the legitimate medical, commercial and scientific needs of the public.

The mission of the Drug Enforcement Administration (DEA) is to ensure the safety and health of American communities by combating criminal drug networks bringing harm, violence, overdoses, and poisonings to the United States. To accomplish this mission, the DEA employs approximately 10,000 personnel throughout the world – Special Agents, Diversion Investigators, Intelligence Analysts, Chemists, and professional staff – across 241 domestic offices in 23 Divisions and 93 foreign offices across the globe.
