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.

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 FDA's list of plant-producible cannabinoids, due Feb 10, 2026, is still unpublished.
final June 1, 2026
