This is kind of tricky. Although HHC isn’t technically a THC, it does produce similar effects—if you use enough of it. 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. Manufacturers haven’t yet figured out a cost-effective way to separate high-potency HHC from its low-potency twin, so commercial HHC—which is a mix of the two forms—may be something of a crapshoot for the buyer. But HHC does have noticeable effects. Reports from users generally describe the HHC high as being somewhere between delta 8 and delta 9 THC. Pretty much everything we know about HHC’s effects and side effects is anecdotal. That said, users report the same set of side effects familiar to delta 9 THC users: anxiety and paranoia, dry mouth, dry and red eyes, hunger, and insomnia.
