Missouri Marijuana Laws: A Complete 2026 Guide
Missouri has a medical and recreational use cannabis program, both of which are regulated under Article XIV of the Missouri Constitution. This guide will outline marijuana possession limits, growing regulations, penalties for violation, and the distinction between medical and recreational users in Missouri as of 2026.
Is Marijuana Legal in Arizona?
Yes. Medical marijuana has been legalized in Arizona since the year 2010 through the passing of Proposition 203, and recreational marijuana was legalized through Proposition 207, “Smart and Safe Arizona Act” in November 2020. Under the recreational marijuana law, Arizona citizens and non-citizens who are 21 years or above can legally grow, use, and purchase cannabis without a medical card.
Is Marijuana Legal in Missouri?
Yes. Missouri legalized medical marijuana in November 2018 under Amendment 2 to the constitution and legalized adult-use marijuana in November 2022 under Amendment 3. In addition, Amendment 3 repealed the medical cannabis-only amendment and replaced it with an amended version under Article XIV of the Missouri Constitution, which governs both markets.
Missouri Marijuana Possession Limits
The amount of cannabis that is permitted to be possessed by a person in Missouri would depend on whether one is considered an adult-use user or a registered medical cannabis patient in Missouri.
For adult-use users who are 21 years old and above:
- Up to 3 ounces of dried and unprocessed cannabis or its equivalent
For registered medical cannabis patients:
- Up to 60 days’ supply that may be extended up to 90 days if the excess quantity is kept in a Department-approved, enclosed, and locked facility.
State residency is not required in Missouri for a person to be registered as a medical cannabis patient.
Missouri Marijuana Cultivation Laws
Missouri permits home cultivation for recreational and medical users, although a special cultivation permit is necessary in each case. Recipients of the medical card can get another permit known as the patient cultivation card at the cost of an extra $50, enabling the individual to cultivate the drug on his/her own at home with plants not exceeding the set limit by the department. Cultivation of the drug without the appropriate permit is illegal in Missouri.
Missouri Marijuana Penalties
The state of Missouri has already made changes to the penalties surrounding cannabis before legalization:
- If an adult over 21 years old possesses cannabis at or below the legal limit, there will be no penalty at all.
- If you possess up to 10 grams outside the legal framework, it will be considered a class D misdemeanor (infraction) that includes a fine of $250 to $1,000 without jail time if it is your first offense.
- If the amount is higher, or you grow/sell cannabis without a license, things become more serious.
Where You Can Use Cannabis in Missouri
Using cannabis in Missouri is legal privately but regulated publicly:
- The act of smoking or vaping marijuana is usually banned or restricted by municipal law in most Missouri cities and towns.
- The use of cannabis in a moving automobile is prohibited whether one is driving or being a passenger.
- Property owners and employers may continue to regulate cannabis use on their premises or in the workplace.
Driving and Cannabis in Missouri
Operating a vehicle while intoxicated with marijuana is a crime in Missouri and is treated with the same severity as alcohol DWI. No particular numeric concentration of THC for driving is required in Missouri; however, the level of impairment is determined based on officer assessment and, if necessary, drug recognition evaluation. The existence of a medical card is no defense to an impaired driving violation.
Who Can Legally Recommend Medical Cannabis in Missouri?
Only a physician (MD or DO) or a nurse practitioner who is eligible to practice in Missouri can recommend a patient to use medical marijuana. Debilitating psychiatric conditions such as PTSD can be diagnosed only by a state-licensed psychiatrist. There are no restrictions concerning previous crimes for registration as a patient or caregiver.
Missouri Edibles, CBD, and Product Laws
Cannabis edible products can be sold to medicinal as well as recreational users within the state of Missouri. The hemp-based CBD products with no more than 0.3% THC content are legal in the entire state.
Who Can Legally Recommend Medical Cannabis in Arizona?
Medical marijuana can be recommended by physicians authorized to practice in the Arizona Department of Health Services, namely MDs, DOs, NPs, and NMDs. To participate in the Arizona Medical Marijuana Program, patients have to qualify as eligible according to the Arizona Medical Marijuana Act and receive the registry identification card.
Arizona Edibles, CBD, and Product Laws
Edibles made from cannabis are legal in Arizona according to the Smart and Safe Arizona Act; these edibles can be obtained by both medical marijuana users and recreational marijuana users from dispensaries that have licenses. Another product that is legal in Arizona is the CBD oil that is made from hemp and does not exceed 0.3% of THC.
