United States Drug Enforcement Administration

All available indicators—including investigative intelligence, case initiations, seizure and arrest data, abuse indicators, and anecdotal information—indicate that opioids present the greatest illegal drug threat to the Drug Enforcement Administration (DEA) Chicago Field Division (CFD), which encompasses the states of Indiana, Minnesota, North Dakota, Wisconsin, and the Northern and Central U.S. Federal Judicial Districts in Illinois. Although this threat is affecting urban and suburban areas most severely, it has been expanding throughout almost every state.
