NADDIS

The Narcotics and Dangerous Drugs Information System, or NADDIS, is a data index and collection system operated by the United States Drug Enforcement Administration (DEA). Comprising millions of DEA reports and records on individuals, NADDIS is a system by which intelligence analysts, investigators and others in law enforcement retrieve reports from the DEA's Investigative Filing and Reporting System (IFRS). NADDIS is thought to have become the most widely used, if least known, tool in drug law enforcement.
