Medical cannabis is legal in Missouri, any registered patient or caregiver may possess up to 4 ounces of cannabis. A registered patient or caregiver over the age of 18 may apply for a home cultivation license. Patients may also purchase up to 4 ounces of cannabis, or its equal in other forms, per 30 day period from state licensed retailers. Missouri does not recognize out of state medical cannabis cards. Over the years, Missouri has continued to show flexibility in regard to their qualifying conditions list, allowing doctors to use their professional judgment as to whether or not medical cannabis may assist a patient. Details on how these laws apply to patients and medical professionals can be found below.

Although cannabis expungement has not occurred in Missouri, Amendment 3 was passed in 2022 to legalize marijuana use for adults. This prevents individuals from being subject to criminal prosecution and began movements towards cannabis expungement in the state of Missouri.

Home cultivation is allowed in Missouri, for medical cannabis patients and caregivers. Six flowering marijuana plants, six non-flowering marijuana plants (over fourteen inches tall), and six clones (plants under fourteen inches tall) at any given time in a single enclosed facility. Growers must apply for a separate Patient Cultivation Card and pay a $53 fee. The card is separate from a medical marijuana card.

NOTICE: It can be challenging for patients to determine which businesses offering cannabis products are licensed and approved by the state. Review this list of medical cannabis retailers and/or a list of adult use retailers to find out where to purchase regulated cannabis in Missouri.
