What is CBD?
CBD, short for cannabidiol, is a chemical compound from the cannabis plant. It's a naturally occurring substance that's used in products like oils and edibles to impart a feeling of relaxation and calm. Unlike its cousin tetrahydrocannabinol (THC), it's not psychoactive.
Will CBD get me high?
Nope. The cannabis plant is made up of two main players: CBD and THC. "CBD is the non-psychoactive portion of the plant, so what that means is you won't have any effects like euphoria," says Junella Chin, DO, an osteopathic physician and a medical cannabis expert for cannabisMD. "You won't feel sedated or altered in any way."
What are the health benefits of CBD?
The only CBD medication that is currently FDA-approved is Epidiolex, which the agency approved last year for the treatment of certain types of epilepsy. Many people swear CBD has helped with a slew of other health conditions, including back pain, osteoarthritis, even cancer.
"My practice has patients walking in every day asking about CBD," says Houman Danesh, MD, director of integrative pain management for the Mount Sinai Hospital in New York City. But while there's lots of anecdotal evidence, he says, "it's still very difficult to say" what the real benefits are due to a serious lack of research.
"Right now, you just have pharmacies trying to make some sort of sense out of it and say, 'Yes, it works for this,'" he says, "but that's not the way medicine is practiced—it should be based on evidence, and there's not a lot of evidence to really support these claims."
There are two possible exceptions to this. The first is that some people, for unknown reasons, just react differently to CBD. According to Dr. Chin, about 5% of people say they feel altered after taking CBD. "Usually they're the same people who have side effects from Advil or Tylenol," she says. You never know how your body will react to any new supplement, so when taking CBD for the first time, do so safely under supervision.
It's also crucial to buy third-party-tested CBD for quality assurance (more on this later). Because the FDA doesn't regulate CBD, it is possible to buy a product that is more or less potent than advertised, or even contains small amounts of THC.
