This report, a product of the U.S. Attorney’s Office, Central District of Illinois, Drug Enforcement Administration (DEA), Illinois State Police, and the Illinois Criminal Justice Information Authority, examines the growth and use of methamphetamine (meth) within the state of Illinois between 2010 and 2018. Responding to requests from multiple federal, state, and local law enforcement agencies, the study is to provide a baseline understanding on the threat. The intent of this report is not to pinpoint or identify major meth traffickers, but instead examine long-term and recent developments related to meth in Illinois. This was achieved through an examination of the history, trends, and techniques related to methamphetamine use and distribution, as well as the impact it has on law enforcement in Illinois.
