The caveats that matter

  • A lawful 'hemp product' is capped at 1.25-1.75 mg THC per serving with a CBD:THC ratio of at least 15:1 — THCA flower (100+ mg total THC per gram) cannot qualify
  • Intoxicating cannabinoid products are only lawful through the licensed marijuana system
  • Total THC (delta-9 + THCA) is the operative measure in enforcement actions

Enforcement, in practice

Colorado AG sued a Greeley hemp company in 2024 over THCA/delta-8/delta-9 products exceeding limits; CDPHE and AG actively enforce.
