Overview

Illinois became the first state to legalize recreational cannabis through legislative action (rather than a ballot initiative) when Governor J.B. Pritzker signed the Cannabis Regulation and Tax Act in June 2019. Sales began on January 1, 2020. The law includes notable distinctions between residents and non-residents: Illinois residents may possess up to 30 grams of flower, while visitors are limited to 15 grams. The state has a strong social equity program designed to repair the harms of the War on Drugs.
