HHC was discovered in 1944 by the American chemist Roger Adams while experimenting with the hydrogenation process with the THC molecule in marijuana. To get HHC, it has to undergo a chemical process called hydrogenation, which replaces the carbon bond with hydrogen molecules. The result is a more stable compound with a longer shelf-life that's less potent. HHC made in a lab is semi-synthetic, but it is found to occur naturally in high-potency cannabis plants, making it a minor cannabinoid.  The...
