Cannabidiol (CBD) is a cannabinoid oil that is derived from the cannabis plant. As a result, inflammation and pain may be reduced. As it is not legal in all states, there may be dangers associated with it. In June, the FDA approved the use of Epidiolex, a refined form of CBD oil, for the treatment of two separate forms of epilepsy. In other states, marijuana can be used in a variety of ways.
