Hexahydrocannabihexol (HHCH) is a semi-synthetic
cannabinoid derivative. It was first synthesised by
Roger Adams in 1942 and found to be more potent than either the pentyl or heptyl homologues, or the unsaturated
tetrahydrocannabinol analogue.[1][2]
Legality
HHCH is classified as an "intoxicating cannabinoid" in
Colorado
and requires a license for its manufacture or distribution.[3]
In
Japan, after several people who had eaten gummy candies containing HHCH fell ill, this chemical was officially added to the list of designated substances. And since 2 December 2023, it has been illegal to possess, use, or sell it.[4]
