Public Act 101-27
(Cassidy, D-Chicago; Steans, D-Chicago) decriminalizes possession of small amounts of cannabis and replaces it with a tax and regulation system. A resident of Illinois (21 or older) may purchase cannabis products and possess 30 grams of cannabis flower, no more than 500 mg of THC in cannabis-infused product, and five grams of cannabis concentrate. It creates an automatic expungement through the governor’s clemency process for convictions up to 30 grams. For amounts of 30-500 grams, the state’s attorney or the individual can petition the court to vacate the conviction. Makes other changes. Effective January 1, 2020.
