    Hemp Act not enforced against the businesses suing over it until Nov 19
    Illinois · Enforcement paused for named businesses only · ILHAA v. Raoul, N.D. Ill. No. 1:26-cv-13799
    Applies only to the six plaintiffs in ILHAA v. Raoul (N.D. Ill. No. 1:26-cv-13799), among them the Illinois Healthy Alternatives Association and its roughly 250 member companies. The state agreed not to take any enforcement action under the Hemp Act against them until Nov 19, when a federal judge hears their request for a temporary restraining order and preliminary injunction. The law itself still takes effect Nov 12, and it applies to every other business from that date.

    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.

    Illinois Hemp Act: 0.4 mg per container cap, total THC, smokable and vape hemp banned
    Illinois · Effective date · SB 3222 (P.A. 104-463)
    Nov 12, 2026: the Industrial Hemp Act is repealed and replaced. Hemp is measured by total THC including THCA (0.3% dry weight); a final hemp-derived product over 0.4 mg combined THC and similar cannabinoids per container is not hemp and is treated as cannabis; final consumer products cannot be intended for smoking or vaping; cannabinoids made outside the plant are excluded; lab testing, child-resistant packaging and a manufacturer license apply. 21+ has applied since June 12, 2026. This Illinois date does not move with the federal Dec 11 delay.
  • 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.

What is Delta-10 THC?

Delta-10 tetrahydrocannabinol, a double-bond position isomer of delta-9 THC. Commercial delta-10 is made by acid conversion of hemp CBD, so state law reaches it through converted and synthetic cannabinoid bans, named isomer lists and total-THC definitions. Federally it rides the hemp definition until the Pub. L. 119-37 sec. 781 change.
