CBD oil is created by extracting CBD from the cannabis plant and diluting it with a carrier oil, such as coconut or hemp seed oil. It's gaining traction in the health and wellness sector, with some scientific studies indicating that it may alleviate symptoms of diseases such as chronic pain and anxiety. However, you can't buy CBD oil at your local grocery store; it's legal in all 50 states but remains illegal at the federal level. The main difference between hemp and marijuana comes down to THC levels. Marijuana contains high amounts of THC, while hemp contains low amounts of THC. The government regulates how much THC can be in a mixture of THC and CBD, which is why you don't find any traces of THC in CBD products. This also means that you cannot get high off of CBD alone without also ingesting THC (which is present in small amounts in both hemp and marijuana plants). Real CBD oil is extracted from industrial hemp and its purity is verified by testing for contaminants including cannabinoids, amino acids, fats, sugars, fibers, proteins, polysaccharides, and vitamins. Because it's not derived from marijuana, CBD does not contain any of the psychoactive substances associated with marijuana use including THC, CBN, and delta-9-tetrahydrocannabinol. Cannabis has been used for medicinal purposes since before modern medicine existed.
