HHC is partially legal in Hawaii. HHC is not textually banned in Hawaii as a cannabinoid. However, this state prohibits smokable and inhalable hemp, so hemp flower, hemp leaf, cigarettes, and vapes are illegal.
This regulation also prohibits cannabinoid-infused foods and beverages, such as gummies. For the time being, the only products allowed in Hawaii are tablets, capsules, tinctures, and soft gels that do not exceed the 0.3% THC threshold.
Most US states don’t have any laws covering HHC. Despite this compound being around for decades, it seems lawmakers haven’t heard of it yet. Because of this, HHC is legal in most but not all US states. Here’s a snapshot of the current state of HHC legality in the United States.
