Watchenforcement paused for named businesses only in 6 days (ILHAA v. Raoul, N.D. Ill. No. 1:26-cv-13799); enforcement date in 28 days (H.R. 6500 (Pub. L. 119-103) / Pub. L. 119-37 Sec. 781)

    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 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.

    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    Nov 12, 2026: the Industrial Hemp Act is repealed and replaced.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.
