The Illinois Cannabis Market

Illinois was the first state to legalize recreational cannabis through its legislature rather than a ballot initiative, signing the Cannabis Regulation and Tax Act in June 2019. The law included some of the strongest social equity provisions in the country, directing 25% of tax revenue to community reinvestment in areas most impacted by the war on drugs.
