JUN 2023REFORM
Automatic expungement deadline
Courts work toward Amendment 3βs mandate to automatically review and expunge eligible nonviolent cannabis convictions. More than 140,000 records are ultimately cleared β among the most comprehensive expungement provisions written directly into a legalization measure.
FEB 3, 2023LEGALIZATION
Adult-use retail sales begin
Existing medical dispensaries begin adult-use sales just 87 days after the vote β one of the fastest voter-approval-to-retail transitions in the country. DHSS issued licenses a day earlier than its announced February 6 date.
SOURCE βDEC 8, 2022LEGALIZATION
Possession legal; Amendment 3 takes effect
Adults 21+ may possess up to three ounces and home-cultivate with a registration card. Because legalization is enshrined in the state constitution, the legislature cannot amend or repeal it β only another voter amendment can.
NOV 8, 2022LEGALIZATION
Voters approve Amendment 3
Missouri voters legalize adult-use cannabis 53% to 47% via constitutional amendment, also creating an equity-focused microbusiness license category and a 6% retail excise tax.
SOURCE βOCT 2020PROCEDURAL

Missouriβs first licensed medical cannabis sales launch, building the dispensary and cultivation infrastructure later converted to adult-use.
NOV 2018LEGALIZATION
Voters approve medical cannabis (Amendment 2)
Missouri voters approve Amendment 2 with about 66% support, establishing a constitutional medical cannabis program under the Department of Health and Senior Services.
