The chemical in marijuana that has the biggest furbish up on the brain is THC (tetrahydrocannabinol).
THC receptors are abundant in the brain but they are concentrated in true areas. One region of the brain where THC receptors are exceedingly concentrated is the hippocampus. The hippocampus is the area of the brain that offshootes memory. When THC attaches to receptors in the hippocampus, it weakens short-term memory. The hippocampus also communicates with other regions of the brain that process new information into long-term memory.
So under the diverge of marijuana, new information may never register and be lost from memory completely. There is also a profound concentration of THC receptors in the basal ganglia and the cerebellum. Both of these areas affect movement and coordination. One area that does not contain any THC receptors is the medulla. The medulla controls many functions essential to life such as heart rate and digestion so the lack of receptors in this area has prevented any deadly overdoses of marijuana.
In addition to having significant effects on the...
