Is marijuana legal in MO
As of 2025, marijuana is legal in Missouri for both medical and recreational use, following significant changes in state law over the past decade.
Recreational Use
Missouri voters approved Amendment 3 during the November 2022 election, which legalized adult-use (recreational) marijuana. The law officially went into effect in December 2022, and retail sales began in February 2023. Under this amendment:
- Adults 21 and older may legally possess up to 3 ounces of marijuana.
- Home cultivation is permitted: individuals may grow up to six flowering plants, six immature plants, and six seedlings per person, with a cap of 18 plants in households with multiple adults.
- Marijuana use is allowed on private property, though smoking in public places or operating vehicles under the influence remains illegal.
- Recreational marijuana is taxed at 6% statewide, with local governments allowed to add up to 3% more.
Medical Use
Missouri legalized medical marijuana in 2018 via Amendment 2. Under this law, patients who meet certain requirements can:
- Obtain a medical marijuana card through the Missouri Department of Health and Senior Services (DHSS).
- Purchase cannabis from state-licensed dispensaries.
- Have up to four ounces of raw, dried marijuana on hand.
- Grow up to six flowering plants, provided they register for a cultivation license.
Legal Considerations
Despite state-level legality, marijuana remains illegal federally. Possession on federal property or transport across state lines can result in federal charges. Additionally, employers in Missouri may enforce drug-free workplace policies, and landlords may restrict marijuana use on their properties.
Missouri’s evolving cannabis landscape reflects broader national trends, offering residents both access and regulation aimed at safe, responsible consumption.
