No. Hawaii prohibits synthetic and chemically converted cannabinoids at hemp retail. HAR Chapter 11-37 names delta-8 THC produced by converting CBD on the list of banned synthetic cannabinoids, alongside delta-10, THC-O, HHC, and HHC-O. The only delta-8 that can lawfully appear in a manufactured hemp product in Hawaii is delta-8 naturally present in the hemp plant and extracted without isomerization, which is a vanishingly small fraction of the commercial market. HRS Section 328G-3 also independently prohibits inhalable hemp products, which removes most delta-8 vapes and cartridges regardless of cannabinoid origin.
