Cannabis and Neuropsychiatric Disorders: An Updated Review. Acta Neurol Taiwan. 2019 Jun 15;28(2):27-39 Authors: Chayasirisobhon S Abstract Cannabis plant has the scientific name called Cannabis sativa L. Cannabis plant has many species, but there are three main species including Cannabis sativa, Cannabis indica and Cannabis ruderalis. Over 70 compounds isolated from cannabis species are called cannabinoids (CBN). Cannabinoids produce over 100 naturally occurring chemicals. The most abundant chemicals are delta-9-tetrahydrocannabinol (THC) and Cannabidiol (CBD). THC is psychotropic chemical that makes people feel "high" while CBD is nonpsychotropic chemical. However, cannabinoid chemicals are not found only in the cannabis plant, they are also produced by the mammalian body, called endocannabinoids and in the laboratory, called synthesized cannabinoids. Endocannabinoids are endogenous lipid-based retrograde neurotransmitters that bind to cannabinoid receptors, and cannabinoid receptor proteins that are expressed throughout the mammalian central nervous system including brain and peripheral nervous system. There are at least two types of endocannabinoid receptors (CB1 and CB2) which are G-protein coupled receptors. CB1 receptors are particularly abundant in the frontal cortex, hippocampus, basal ganglia, hypothalamus and cerebellum, spinal cord and peripheral nervous system. They are present in inhibitory GABA-ergic neurons and excita...
