Watchenforcement date in 28 days (H.R. 6500 (Pub. L. 119-103) / Pub. L. 119-37 Sec. 781)
  • in 28 days
    Federal hemp redefinition, Dec 11 piece: total THC 0.3% and 0.4 mg total THC per container
    Federal · Enforcement date · H.R. 6500 (Pub. L. 119-103) / Pub. L. 119-37 Sec. 781
    Pub. L. 119-103 (continuing resolution, Sept 2, 2026) delayed the rest of the Pub. L. 119-37 sec. 781 hemp definition to Dec 11, 2026 (CRS IF13136, Sept 28, 2026): hemp is measured by total tetrahydrocannabinols including THCA (0.3% dry weight), and any final product over 0.4 mg combined total THC and cannabinoids with similar effects per container leaves hemp. A product that leaves hemp is marijuana, Schedule I, in every state.

    Federal hemp redefinition, Nov 12 slice: THC-O acetate, which the plant cannot produce, leaves hemp
    Federal · Enforcement date · H.R. 5371 (Pub. L. 119-37, Sec. 781)
    Pub. L. 119-103 sec. 2019 (Sept 2, 2026): until Dec 11, 2026 the Pub. L. 119-37 sec. 781 amendments apply only to products with cannabinoids not capable of being naturally produced by a Cannabis sativa plant (7 U.S.C. 1639o(1)(C)(ii)(I) and (iv)(I)). THC-O acetate is made only by acetylating THC outside the plant, so products containing it leave the federal hemp definition on Nov 12, 2026 and fall in the Schedule I tetrahydrocannabinols listing.
  • took effect
    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.
