The federal hemp THC ban (November 12 and December 11, 2026): what’s banned, what’s still legal, and how to keep legal THC in your state

Key takeaways
- The federal hemp ban is a redefinition of “hemp” in Public Law 119-37 (Section 781). Products that no longer fit the definition become marijuana under the Controlled Substances Act.
- Two dates: November 12, 2026 for cannabinoids the plant cannot naturally produce (THC-O and similar); December 11, 2026 for everything else, including the 0.4 mg total THC per container cap (delayed from Nov 12 by H.R. 6500, Public Law 119-103).
- Delta-8, delta-10, THCA flower, hemp-derived delta-9 gummies and THC drinks all fail the 0.4 mg cap. CBD with no more than 0.4 mg total THC per container survives; full-spectrum is a gray zone.
- State medical and adult-use programs are not affected. Dispensary products are already marijuana under state law. Texas, Ohio and California had restricted intoxicating hemp before the federal dates.
- Bills to delay to 2028 (H.R. 7024 / S. 3686), repeal (H.R. 6209) or regulate (H.R. 9830, H.R. 10079) are all stuck in committee as of October 2026.
- In medical-only states the medical card is the legal route that remains; in adult-use states it is one of two.
