Cannabis Laws in Missouri

In 2018, voters approved Amendment 3 which legalized medicinal marijuana and recreational marijuana for adults 21 years or older. Cannabis Laws in Missouri may purchase up to three ounces of cannabis in one transaction at licensed dispensaries. Adults may also cultivate up to six plants at home for their own personal use, as long as they comply with state cultivation regulations. It is illegal to possess more than three ounces of cannabis in public, in moving vehicles, or in public schools.

Cultivation, testing, and production facilities must be fully compliant with all applicable laws and regulations to maintain operational approval. They must also provide quality assurance systems and establish procedures for addressing any issues that arise. Signs and advertising must be consistent with all state laws, including restrictions on content that is attractive to children and prohibition of false or misleading statements. Facilities must also have a designated agent responsible for inventory management and record keeping.

Cannabis Laws in Missouri: What You Should Know Before You Buy

Employers may still set policies that restrict the possession or consumption of cannabis on their property, but they cannot discriminate against employees based on their medical marijuana card status. This is similar to how Missouri employers may handle alcohol use on the job.

The passage of Amendment 3 has also set in motion the expungement of records for thousands of Missourians who have been convicted of nonviolent marijuana-related offenses. This is an important step to help people whose previous offenses have made it difficult for them to find work, especially in the growing marijuana industry.
