‘In doses used as a food supplement, CBD poses few risks, and side effects are unusual but can include a dry mouth or drowsiness,’ reveals Dr Brewer. ‘Higher doses used medically are well tolerated, and there are no serious safety concerns. A World Health Organization report issued in 2017 concluded that cannabidiol does not appear to have abuse potential or cause harm.'

Not much, as far as humans are concerned—at least not yet. The vast majority of studies have been on animals, as of yet, and there are few high-quality studies on humans. Even the oil’s effect on pain—something that CBD oil is popularly used for—isn’t proven. “The studies available are small or not well designed,” says Dr. Devinsky. “There’s a lot of religion out there, but not a lot of data.”

It is important that you understand the basics of CBD, too. CBD is just one type of cannabinoid that is found in cannabis. Cannabis contains numerous cannabinoids, and CBD is just one of them. CBD is made from the stalks, leaves, and roots of the cannabis plant, unlike other strains that are all made in different ways. It also does not have any THC oil, which many of cannabis strains do. THC oil can induce sleepiness and a high just like it does in marijuana and weed. THC is also another strain belonging to the cannabis family again much like marijuana, weed, and hemp. Hemp has similar properties as CBD and it is also very much legal around the USA.
