The answer is not straightforward, as CBD and CBN are two different cannabinoids that have different origins and effects. CBD is derived from the hemp plant and is non-psychoactive, meaning it does not make you feel high. CBN is the product of the oxidization of THC, the psychoactive chemical in marijuana. CBN is also non-psychoactive, but it has more sedative properties than CBD. CBD oil may contain trace amounts of CBN, but not enough to produce significant effects. To get the benefits of both cannabinoids, some people use products that combine CBD and CBN in a specific ratio, such as 1:1 or 3:1.
