Although hemp and marijuana come from the same species of cannabis plant, hemp has little to no THC. This means that consuming hemp is legal in the U.S. and will not cause you to become intoxicated or impaired.
Potential Risks of Hemp Oil

Hemp oil is made from hemp seeds. In one serving of hemp seeds (3 tablespoons), you’ll find the following:
However, it is not clear whether it would be advisable to consume higher doses of CBD than is currently in these products. “I do worry that if people believe a small amount is good and it’s completely safe, they may believe a large amount is better, says Dr Sarah Jarvis, GP and Clinical Director of Patient Info."
Coffees and cakes may contain between 5–10mg of CBD. But clinical trials administer doses of around 100–1,500mg per day, with medical supervison.
"CBD is actually hard to cook with. It has a disgusting taste", says Greg Hanger, head chef at Kalifornia Kitchen in London, who has created an entire CBD afternoon tea . Greg pays attention to the type of oil that the CBD is mixed with, saying "coconut oil CBD is great in Thai cooking balanced with coriander, ginger and lime. Olive oil CBD is great for Middle Eastern foods like hummus or you could even mask the flavour with rosemary and put it in cheesy sauce or mashed potatoes ."
"But there is no good scientific evidence that these consumer products have any real benefits.
“When you cook with CBD, you have to be careful not to heat the mixture at too high a temperature”, advises Meg. A search on CBD websites brings up details of CBD evaporating and losing its 'health' properties past 160–180C, though "there is also little understanding of what happens to CBD when you cook it or add it to a drink", says Professor Sumnall.
"Many of the CBD products available on the high street contain so little CBD that you would need to consume vast quantities to even approach some of the doses that are administered in clinical trials of medicines", concludes Sumnall.
"There is a greater public awareness of the potential therapeutic uses of medical cannabis and cannabinoids such as CBD, particularly in light of the UK government decision to permit some cannabis prescriptions in response to high-profile campaigns by the families of children affected by severe epilepsy," says Professor Sumnall.
It's not the psychoactive cannabinoid that gets you high, called THC. Instead it's a product believed by its high-street users to have medicinal properties, such as relaxation and pain-, nausea- and anxiety-relief, although studies are not conclusive.
