HHC, or hexahydrocannabinol, is a cannabinoid that occurs naturally in cannabis plants, but in amounts too small to make extraction cost-effective. It can also be synthesized from compounds found in legal hemp plants. HHC is a minor cannabinoid that has started to garner more interest in terms of research for medicinal use. HHC is considered a semi-synthetic cannabinoid because the process of creating HHC is more intensive than a simple hemp extraction. The process of hydrogenating hemp-derived cannabinoids under pressure with a catalyst like palladium produces a "semi-synthetic" cannabis compound. Although HHC isn’t technically a THC, it does produce similar effects if used enough. When it’s produced in the lab, an HHC batch is a mix of active and inactive HHC molecules. The active HHC binds well with your body’s cannabinoid receptors; the others don’t. HHC is sold openly as a replacement to cannabis and THC products in a range of highly attractive branded and unbranded products, including low-THC cannabis (hemp) flowers and resin, vape pens, e-liquids and e-liquid cartridges for use in e-cigarettes, and edibles and oils.
