Hemp delta-9 is legal in California, but AB 45 clarifies a lot of state law surrounding hemp products. Some important points established by the legislation include: making it so that adding industrial hemp to foods, beverages, dietary supplements and more doesn’t constitute “adulteration,” requiring a COA for any product sold, banning inhalable products until a tax structure can be implemented and applying the 0.3% THC by dry weight limit to any THC, effectively banning at least most delta-8 products on the market.
