According to the National Cancer Institute, Delta-8-THC can be defined as: “An analogue of tetrahydrocannabinol (THC) with antiemetic, anxiolytic, appetite-stimulating, analgesic, and neuroprotective properties. [Delta-8-THC] binds to the cannabinoid G-protein coupled receptor CB1, located in the central nervous system…This agent exhibits a lower psychotropic potency than [delta-9-THC], the primary form of THC found in cannabis.” Delta-8-THC is chemically different from delta-9-THC, by only a few atomic bonds and still offers a potent high of its own. While delta-8-THC only exists naturally in fractions of a percent, companies are finding value in concentrating esoteric cannabinoids for their unique effects and applications.
