Cannabis in Illinois
Illinois made history in June 2019 when it became the first state to legalize recreational cannabis through the legislature rather than a voter ballot measure. The Cannabis Regulation and Tax Act was signed by Governor J.B. Pritzker and included robust social equity provisions.
Recreational sales launched on January 1, 2020, with long lines at dispensaries across the state. Chicago and its suburbs are home to the majority of dispensaries, with additional locations throughout the state.
Resident vs. Non-Resident Limits
One important distinction in Illinois: purchase limits differ based on residency. Illinois residents can buy up to 30g of flower, 5g of concentrate, or 500mg of THC in edibles. Non-residents (including tourists) are limited to exactly half those amounts.
This means out-of-state visitors can purchase up to 15g of flower, 2.5g of concentrate, or 250mg of THC in infused products per transaction.
