Missouri Marijuana Laws

Missouri Marijuana Laws: Overview

Marijuana (cannabis) is no longer illegal in all states, although state laws legalizing its medical or recreational use remain in conflict with federal drug policy. And while Missouri still has some of the toughest marijuana laws in the nation, voters approved a constitutional amendment legalizing medical marijuana in 2018 (enacted on Dec. 6, 2018, but the infrastructure for setting up licensing, dispensaries, etc. will take longer).

First-time offenders who possess up to 10g may have to pay a fine of up to $500 but won't face the possibility of incarceration. Sentences for those convicted of sales, trafficking, or cultivation are much stiffer. For instance, you may be sentenced to as many as seven years in prison for selling less than five grams of cannabis. Selling 30 or more kilograms can get you life in prison, while penalties for cultivation are based on the weight of the plants (which are substantially heavier before being processed).

While you may be able to get probation or a reduced sentence for your first simple possession offense, conviction on marijuana charges could dramatically derail your life plans.
