What’s different in Missouri

Missouri's cannabis rules are in the state constitution, Article XIV. Section 1 covers medical marijuana and Section 2 covers adult use. The current text of both took effect on December 8, 2022. One agency, the Department of Health and Senior Services' Division of Cannabis Regulation (DCR), licenses growers, makers, testing labs and dispensaries, and issues patient, caregiver and home-grow ID cards.

A city or county can ban adult-use dispensaries only by a public vote. The vote can happen only at the November general election in a presidential election year, and at least 60 percent must vote yes.

Using cannabis in a public place is against state law, unless it is an area licensed for it. Smoking in public can bring a fine of up to $100. You also can't use cannabis at a dispensary or drive under its influence.

Adult-use purchases carry a 6% state tax, and cities and counties may add up to 3%. Medical purchases carry a 4% state tax.

Hemp products are changing. DCR says delta-8, delta-10, THCA and similar products sold in gas stations and smoke shops are outside its authority and have not been tested by a licensed marijuana lab. A 2026 state law (HB 2641) says that from November 12, 2026, hemp-derived cannabinoid products may be made and sold only by businesses that DHSS licenses.

Licensed does not mean risk-free. DCR has recalled licensed products, including pre-rolls that failed testing for mold (Aspergillus) in September 2026.
