Federal posture

Federal gray area. THCa - federally contested: hemp on the statute's delta-9-only text, marijuana on DEA's post-decarboxylation reading; resolved against THCa Federal detail

Pending deadlines

  • 2026-11-12 · Federal · Federal hemp redefinition: Total THC = (THCa x 0.877) + delta-9 <= 0.3% + 0.4 mg total THC per container cap (H.R. 5371 (Pub. L. 119-37, Sec. 781))
    Effective Nov 12 2026: total-THC formula makes most THCa flower federally illegal (THCa is the prime target). DEA already applies a total-THC stance; OH SB56 + TX DSHS + 12 states moving.
  • 2026-12-11 · Federal · Federal hemp redefinition, Dec 11 piece: total THC 0.3% and 0.4 mg total THC per container (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.
