H Aych See or Hexahydrocannabinol is another cannabinoid with similar effects to Delta-9 THC. H Aych See is the doomsday prepper’s dream as it is resistant to oxidation, heat, and UV light. Being resistant to these means it loses its potency at a MUCH slower rate than Delta-9 THC. H Aych See is a hydrogenated form of THC. Hydrogenation is the process of adding hydrogen atoms to a chemical structure to stabilize it. Many users report that HHC gives a euphoric type of high along with a gradual increase in mood, and activity stimulation, all while still having the ability to remain in control.
