New neurotransmitter system found in THC Distribution Study. Scientists attached radio active markers to the THC molecules that enable them to be photo graphed.
THC carried by the blood separates evenly throughout the brain, but surprisingly, the THC molecules quickly come to rest in specific areas of the brain. Why do our brains produce a natural receptor site for the THC? (All mammals have natural receptor sites for THC) There is barely a physiological system in which endocannaboids (natural) are not involved.
