Last verified October 24, 2026 · Last major change May 2026
Illegal. Illegal; voters rejected adult-use legalization (State Question 820) in March 2023.
Legal. Physicians may recommend a medical license without a list of qualifying conditions; a 2026 law (House Bill 4454) adds edible packaging, labeling and shape rules effective Nov. 1, 2026.
Patients can buy flower, vapes, concentrates, edibles, tinctures and topicals at licensed dispensaries, and from Nov. 1, 2026 newly made edibles may not be shaped or packaged to look like candy or appeal to children. Limits: No statewide THC potency or per-serving cap found. HB 4454 (effective Nov 1, 2026) requires edible and drink labels to show servings and THC per serving but sets no mg limit. Possession limits: 3 oz on the person, 8 oz at home, 1 oz concentrate, 72 oz edibles, 72 oz topicals, and 6 mature plus 6 seedling plants.
Hemp-derived delta-8 products and THC drinks are sold over the counter; a 2026 bill to bar hemp drink sales to people under 21 (House Bill 4248) did not become law. A federal 0.4 mg total THC per container cap starts Dec. 11, 2026.
Legal. Hemp-derived delta-8 and delta-10 are sold at general retail; in an April 29, 2025 letter, the governor asked state agencies to coordinate enforcement against psychoactive hemp products such as delta-8.
Possession without a patient license is a misdemeanor with up to 1 year in jail and a $1,000 fine; up to 1.5 oz by a person who can state a medical condition is fine-only, up to $400.
In danger. Federal law excludes cannabinoids the plant cannot produce naturally (such as THC-O) from hemp on Nov. 12, 2026, and converted cannabinoids such as delta-8 made from CBD, plus hemp products over 0.4 mg total THC per container, on Dec. 11, 2026. House Bill 4454's edible packaging rules take effect Nov. 1, 2026.
In danger on this tracker: In a state where recreational cannabis is not legal, an enacted law, court ruling or enforcement action is removing THC products adults can legally buy today.
