Missouri Constitutional Amendment 3 legalized recreational marijuana in November 2022, but consumption in public places, motor vehicles, and on federal property remains illegal in Kansas City, with municipal fines for violations.
Missouri voters approved Constitutional Amendment 3 in November 2022 legalizing recreational marijuana for adults 21 and older. The amendment, codified in Missouri §195.005 et seq., permits possession of up to three ounces and home cultivation of up to six flowering plants with a registration card. Public consumption remains prohibited statewide, including in parks, sidewalks, restaurants, bars, and motor vehicles. Kansas City Code Chapter 50 incorporates these limits, treating public consumption as a municipal infraction with fines up to $100. Open container in a vehicle exposes drivers to additional motor vehicle penalties. Federal property including KCI Airport, post offices, and VA facilities prohibits possession entirely under federal law.
Public consumption fines up to $100; vehicle open container adds traffic penalties; federal property possession can trigger federal misdemeanor charges.
