CBD oil, short for Cannabidiol, is a natural compound found naturally in the hemp plant. The legality of CBD oil and hemp is still under debate. Cannabis sativa is the origin of hemp and marijuana. However, marijuana has high levels of THC (tetrahydrocannabinol), a naturally occurring chemical compound that produces the psychoactive 'high' experienced when consumed. Hemp, on the other hand, has a very low THC content, which means that CBD does not have the capacity to intoxicate.
