The Role of Cannabidiol in Neurological Disorders.

None: Cannabis has been used for both recreational and medicinal purposes for more than 4 millennia. Cannabis has been studied in various medical disorders including neurological disorders. There are well-known risks of long-term use of cannabis, including low motivation, lowered cognitive capabilities, and diminished IQ and brain mass. Cannabinoids are compounds in cannabis that are known to have therapeutic potential. The most abundant chemicals in cannabinoids are delta-9-tetrahydrocannabinol and cannabidiol. Delta-9-tetrahydrocannabinol has psychotropic effects that limits its use as a pharmacotherapeutic agent. Cannabidiol is a nonpsychotropic chemical and therefore has become a compound of interest for clinical researchers to study its therapeutic potential. This article reviews the efficacy and safety of cannabidiol in various neurological disorders in humans.
