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