On June 25, 2019 Illinois Governor JB Pritzker signed the Illinois Cannabis Regulation and Tax Act, “The Cannabis Act” which legalized recreational cannabis beginning January 1, 2020 for adults aged 21 years and older. Illinois residents are permitted to possess 30 grams of cannabis flower, 5 grams of cannabis concentrate, and 500 milligrams of THC contained in a cannabis-infused product. The possession limits are to be considered cumulative. The legalization of adult-use marijuana for recreational purposes in Illinois does not modify the state’s medical cannabis pilot program.
