The Endocannabinoid System
Cannabidiol (CBD) is one of the naturally occurring cannabinoids found in cannabis plants. It is a 21-carbon terpenophenolic compound which is formed following decarboxylation from a cannabidiolic acid precursor, although it can also be produced synthetically.
There are two main cannabinoid (CB) receptors, CB1 which is primarily located in the central nervous system with some expression in peripheral tissues and CB2 receptors, which can be found in the periphery on cells with immune function and in the gastrointestinal tract and at low densities in the central nervous system. CBD may offer an option for treating different types of chronic pain,
anxiety, and for patients who suffer through the misery of insomnia, studies suggest that CBD may help with both falling asleep and staying asleep.
In humans, CBD exhibits no effects indicative of any abuse or dependence potential. To date, there is no evidence of recreational use of CBD or any public health-related problems associated with the use of pure CBD. Several countries have modified their national controls to accommodate CBD as a medicinal product, including the United States.
