In 2004, the State of Illinois received a grant from the United States Department of Health and Human Services (HHS) Substance Abuse and Mental Health Services Administration's (SAMHSA) Center for Substance Abuse Treatment (CSAT) to implement a client choice, voucher program for substance abuse clinical treatment and recovery support services. This program, Access to Recovery (ATR), provided substance abuse treatment and recovery support services to over 8,600 individuals in Illinois between 2004 and 2007.

In March 2007, CSAT announced the availability of a second round of funding to support ATR programs in States, Territories, the District of Columbia, and Tribal Organizations. Illinois submitted an application to continue ATR-supported services in Cook County and the 5th and 6th Illinois Judicial Districts, as well as to expand services to the 10th Judicial District in West-Central Illinois. A notice of acceptance of this application was received in September 2007, and the Illinois Office of the Governor delegated responsibility for administration of the Illinois ATR-II Program to the Illinois Department of Human Services, Division of Alcoholism and Substance Abuse (DHS/DASA). Since that time Illinois has also expanded methamphetamine treatment to include DuPage County and Southern Illinois, in the 1st, 2nd, 4th and 20th Judicial Districts.
