Delta-8 THC: 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.

Delta-9 THC: Michigan CRA summarily suspends Loud Labs of Michigan’s hemp processor-handler license and issues notice of intent to revoke over products testing above 0.3 percent delta-9 THC
Michigan · Enforcement action · License HPHL-000047 · Authority (Michigan Cannabis Regulatory Agency) · binds named parties only
Following a March 25, 2026 inspection and May 18, 2026 inventory audit, CRA alleges violation of Section 12(1)(a) of the Industrial Hemp Research and Development Act (intentional possession of cannabis above 0.3 percent delta-9 THC); revocation is required if proven at hearing.

THC-O Acetate: 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 November 12, 2026
HHC-P: Federal hemp redefinition, Nov 12 slice: cannabinoids the plant cannot produce, including HHC-P, leave 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)). HHC-P is not reported as produced by the plant, so on that reading products containing it leave the federal hemp definition on Nov 12, 2026. FDA's list of plant-producible cannabinoids, due Feb 10, 2026, is still unpublished.
