— Annual Project Reports

Update: A revised report has been posted that corrects technical errors but not the substantive conclusions expressed in the original 2023 report. Details on the changes and review process are provided in the preface to the revised report as well as in an addendum.

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.
