Cannabis and the brain: current research into potential medical applications.

"Cannabis" is found in various plants, which contain two molecules of interest: THC (tetrahydrocannabinol) and CBD (cannabidiol). These molecules can produce either "body highs" or "mind highs". Current research is trying to understand how these molecules act on the brain, in the hope to develop new medicines to treat patients for which current clinical treatments fall short. Here, the origin of "cannabis" will be explored, along data on recreational or medicinal/medical use in different countries. Furthermore, we will also explore how THC and/or CBD could be useful to treat some patients.
