If current trends hold, the state is on pace to surpass $1.8 billion in total marijuana sales for the year, fueled by consistent demand from both residents and tourists, as well as gradually decreasing prices.

Illinois legalized marijuana in 2019, allowing those 21 and older to purchase up to 30 grams of dried marijuana, 5 grams of marijuana concentrates, and up to 500 milligrams of THC in marijuana-infused products. Non-residents are allowed to possess half these amounts. The tax rate on marijuana products varies between 10% and 25%, depending on the type of product, and is supplemented by the state’s 6.25% sales tax and local taxes of up to 3.5%.

Revenue from marijuana taxes, after covering the costs of running the state’s marijuana program, is allocated to various initiatives. 35% goes to the General Revenue Fund, 25% supports the Recover, Reinvest, and Renew (3R) Program, and 20% is directed to mental health services and substance abuse programs. An additional 10% is used to pay unpaid bills, another 10% is allocated to the Local Government Distributive Fund for law enforcement training and prevention efforts, and 2% funds public education and safety campaigns.
