There are several isomers of this hydrogenated form of THC. HHC is to THC, what margarine is to butter. By saturating the molecule with hydrogen atoms, the shelf-life of this cannabinoid is extended substantially without affecting the effect profile too much.
HHC concentrate contains three different stereoisomers of HHC and less than 0.2% other cannabinoids. HHC is typically found in both the seeds and pollen of cannabis, meaning that it is a naturally occurring cannabinoid. HHC effects are very very similar to THC, but HHC does have differences. Some people claim it gives them the same euphoric feeling, pain-fighting, and anti nausea/vomiting effects that THC does. HHC is still very new, so there aren’t many studies available to evaluate its potential therapeutic effects — but so far, it seems this cannabinoid offers most of the same therapeutic effect profile as other forms of THC.
HHC has three chiral centers (enantiomers), meaning it has three different forms of it. The differences between the three enantiomers of HHC are important because they show that HHC can bind to two different receptors (CB1 and CB2), but it can only activate one of them (CB1). This means that HHC can potentially treat two conditions at once. Since HHC is not only a naturally occurring cannabinoid found in hemp, it's not a THC type like Delta-8. This means that HHC vapes, gummies, or edibles are currently legal on the federal level and will most likely remain legal on the state level as well.
