Federal hemp status ends for non-naturally-producible cannabinoid products
First of two federal hemp dates now fixed in statute. H.R. 6500 (the Continuing Appropriations and Extensions Act, 2027, signed September 2, 2026) delayed most of the November 2025 hemp redefinition to December 11, 2026 — but products containing cannabinoids "not capable of being naturally produced by a Cannabis sativa L. plant" lose federal hemp status on the original date, November 12, 2026. Cannabinoids the plant can produce but that are converted or synthesized outside it (much of the delta-8 market) stay covered until December 11. See the December 11 entry for the main effective date.
