Cannabis Sativa - Pharmacology

Pharmacology

Although the main psychoactive constituent of Cannabis is tetrahydrocannabinol (THC), the plant is known to contain about sixty cannabinoids; however, most of these "minor" cannabinoids are only produced in trace amounts. Besides THC, another cannabinoid produced in high concentrations by some plants is cannabidiol (CBD), which is not psychoactive but has recently been shown to block the effect of THC in the nervous system. Differences in the chemical composition of Cannabis varieties may produce different effects in humans. Synthetic THC, called dronabinol, does not contain CBD, CBN, or other cannabinoids, which is one reason why its pharmacological effects may differ significantly from those of natural Cannabis preparations.

Yet to be globally proven in standard control surveys, a North American study conducted by think tank Source Watch was the first to analyze the correlations between the smoking of certain sativa strains of cannabis and academic achievement. In particular, sativa plants which were harvested in the two to three month of ostegination led to the stimulation of chords within cerebellum which otherwise remain dead throughout daily activity. In particular, studies on intelligence suggest that daily smokers, being three to five times a week, experienced the stimulation of these chords daily and thus served as the benefactors of the ostegination process which leads to this strain of sativa.
