Hemp oil does have a number of uses and is often marketed as a cooking oil or a product that is good for moisturizing the skin. It is also used in the production of certain soaps, shampoos, and foods. It is also a basic ingredient for bio-fuel and even a more sustainable form of plastic. Hemp has been cultivated and used for roughly 10,000 years, and it definitely has useful purposes. However, a lack of cannabinoids, namely CBD, means that it has little therapeutic value.
Many people still use CBD vape oil from marijuana like UFC fighter Nate Diaz but they are still at risk of failing a drug test. This is because these CBD vape pens made from marijuana contain too much THC. If you are concerned about passing a drug test or don't want to get high you should buy CBD vape oil made from all-natural hemp plants that contain active CBD components, without the psychotropic effects of Tetrahydrocannabinol (THC).
Realistically, you’re going to be looking at a minimum dose of about 40mg CBD if you want to feel effects, at least that’s in my experience. That said, I’ve noticed that dosing can be kind of sensitive – if I take over about 80mg, it seems to start effecting me negatively while a 40-50 mg dose works wonders for me joint pain and sleep. Just my two cents. Best of luck
