Restricted. THCA flower and high-potency concentrates cannot lawfully be sold at Hawaii hemp retail. The Department of Health interim rules at HAR Chapter 11-37 prohibit inhalable hemp products outright and limit allowable edible categories to 1 mg total THC per serving and 5 mg per container. THCA is captured because Hawaii applies a post-decarboxylation total-THC reading rather than the federal delta-9-only standard at harvest. The state's medical cannabis dispensary system under HRS Chapter 329D operates separately and does not stock THCA flower as a hemp product.
