Technically, cannabinoids from marijuana and cannabinoids from hemp are the same, meaning that they have the same properties. However, as previously explained in this FAQ, hemp contains very little to no THC. Perhaps just 10ths of one percent. Marijuana on the other hand is very high in THC (usually between 10% and 25%) and makes you high. This is why you should opt for hemp CBD oil if you intend to use it as a food supplement. If you take THC with CBD, the effects of THC will be diminished as CBD attaches to the same receptors in the endocannabinoid system.
