HHC, or Hexahydrocannabinol, was discovered in 1944 by American chemist Roger Adams when he added a hydrogen molecule to Delta-9 THC during the hydrogenation process. This substance was illegal until today as it was made from THC.
Then, HHC was found to be one of the many natural cannabinoids in the cannabis plant and in 2020. The de Las Heras team analysed a lipid extract of Cannabis Sativa L. CBD (Cannabidiol) seeds, and discovered 43 cannabinoids in it, one of which was HHC (Hexahydrocannabinol).
Hexahydrocannabinol activates CB1 neuroreceptors in the brain creating a feeling of euphoria. The difference with D-9 THC lies in the fact that it tends to provide more of a sense of relaxation than a feeling of psychostimulation.
