No. HHC and HHC-O are named on Hawaii's enumerated list of prohibited synthetic cannabinoids under HAR Section 11-37-3, alongside CBD-isomerized delta-8, delta-10 THC, THC-O, THC-P, THC-H, and THCjd. Commercial HHC is produced through hydrogenation of hemp-derived CBD or delta-9, which is the exact production method Hawaii's rules target. HRS Section 328G-3 also bans inhalable hemp products, which independently removes HHC vapes and disposables from the lawful retail mix.
