Observation

Illinois and Michigan, two Midwest states that have legalized cannabis, both had approximately 4.6% and 3.9% increases in any past year use between 2018-2019 and 2021 among residents 12 years of age or older, respectively. Other Midwest states showed a 3.7% increase over the same time, while there was only a 2% increase across all US states. However, in Illinois there has been no apparent effect of legalizing recreational cannabis use on past-year initiation among those 12 or older over the same time. The initiation rates were comparable to other Midwest states and the U.S.

— Annual Project Reports

Each year in August, as required by statute (410 ILCS 705/55-80), an annual report is produced and submitted to the Illinois Adult Use Cannabis Health Advisory Committee. This committee reports to and advises the Governor's Office on cannabis policy. The annual report summarizes the evaluation project findings of the past-year public health effects of legalizing recreational cannabis. Downloadable copies of the most recent (2022-2023) and previous annual reports in pdf format are available below.
