Missouri AG sends cease-and-desist letters to 33 unlicensed 'dispensaries' and smoke shops selling intoxicating cannabinoid products outside the Article XIV framework
Missouri · Cease and desist · Attorney General (Missouri Attorney General Catherine Hanaway) · guidance to the sector, not self-executing
33 retailers in the St. Louis (18), Kansas City (13) and Springfield (2) regions were ordered to stop selling intoxicating cannabis products, stop child-appealing or confusing packaging and stop selling adulterated products, under the Missouri Merchandising Practices Act; letters cited total-THC above 0.3 percent and contaminants.

Intoxicating Cannabinoid Control Act, RSMo 195.900
Missouri · Effective date · HB 2641 (2026)
Tier 1 (195.900.11(1)(a)) becomes marijuana-only, no contingency: synthesized or non-natural cannabinoids (HHC, converted D8, THCP, EPN class), THCA smokable flower or bud, solid edibles with hemp D9 above natural plant concentration. Manufacturing, testing, transportation and retail sale reserved to Article XIV licensees statewide; $5,000 per unit sold plus class D felony; AG has primary enforcement. No grandfathering or sell-through. Zero-THC products (0.4 mg or less total THC per container, no synthesized cannabinoids) are outside the mandate per the State’s litigation position, ambiguous on the literal text. See law text RSMo 195.900 in the state drawer. The separate federal-timing provision can apply to beverages with naturally produced cannabinoids that do not meet a tier 1 criterion; beverages containing synthesized cannabinoids can be tier 1. Under the current federal extension, products outside tier 1 are generally deferred to December 11, 2026, subject to the statute's federal-contingency condition.
