The chemical, called delta-8 THC, is mostly synthesized from CBD, a non-intoxicating chemical that’s prevalent in hemp.
District Attorney Patsy Austin-Gatson said in January that the possession, sale or distribution of delta-8 is illegal under state law, according to the suit by the firm, Pate, Johnson & Church.
The suit says the district attorney has interpreted “hemp” and “hemp products” incorrectly under state law.
