Illinois Medical Cannabis Guide

Illinois legalised adult-use cannabis on January 1, 2020, becoming the first state to do so through legislative action (rather than a ballot measure). The Cannabis Regulation and Tax Act (SB 1557) includes strong social equity provisions, with a significant share of licences reserved for applicants from communities most harmed by the war on drugs.
