These new components may explain some of its effects on the brain.
You might think that by now marijuana would have been completely analyzed for any possible psychoactive ingredients. To date, almost 150 cannabinoids have been identified in the marijuana plant.
We do not know what all of them actually do in the body, but that has not concerned scientists because the levels of these other molecules are so low. The assumption was that the other cannabinoids were precursors to the two most interesting molecules, CBD and THC. Pharmacological dogma that has been written into the textbooks for decades is that THC produces euphoria.
In recent years, agricultural genetics research has made great progress in breeding plants that produce high amounts of CBD or THC. The assumption has been that these are the only two interesting molecules worth enhancing. Thus, today we have strains of cannabis that produce very high levels of both or either of these molecules.
Recently, two new exciting molecules have been discovered in a marijuana plant. They are variations on the familiar CBD and THC molecules; they have been named cannabidiphorol (CBDP) and Δ9-tetrahydrocannabiphorol (THCP). THCP appears to be thirty times more effective than THC at stimulating the brain’s type one cannabinoid receptor, CB1. This receptor is responsible for producing the euphoria, or the high, associated with marijuana. This means that THCP is thirty times more potent than THC. Therefore, although the level of THCP in the marijuana is quite low, its ability to stimulate CB1 receptors and produce euphoria is quite powerful.
