HHC, which is short for hexahydrocannabinol, is a hydrogenated form of THC naturally present in varieties of cannabis. It’s thought to be roughly 70-80% the strength of THC, meaning it’s more potent than delta-8 and delta-10. Mild-to-moderate doses of HHC induce a euphoric high similar to THC but with more relaxing and sedative qualities akin to delta-8.
