The caveats that matter

  • Since July 23, 2023, products with any detectable amount of THC (including THCA-rich hemp) may only be sold by LCB-licensed cannabis retailers
  • Applies regardless of hemp origin or delta-9 percentage — 'detectable THC' standard is stricter than total-THC states
  • Non-intoxicating CBD without detectable THC remains lawful at general retail

Enforcement, in practice

WSLCB treats unlicensed sale of detectable-THC hemp products as unlicensed cannabis sales.

Last checked 2026-08-06 — laws change. This is decision support, not legal advice.
