By now, you've probably heard someone mention CBD, especially if you live with a chronic condition like pain or anxiety.
As U.S. states begin to legalize both medical and recreational cannabis, the market has enjoyed an influx of readily available CBD. Despite all the publicity, though, many people are unsure of what CBD is, how it can help them, and if it's even legal.
If you're looking to try CBD but aren't sure where to start, we put together this quick, handy guide to answer your questions and help clear up some of the common misconceptions surrounding CBD and its uses.
What is CBD?
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, delta-9-tetrahydrocannabinol (THC), which is the major active ingredient in marijuana, CBD is not psychoactive.
You've probably heard the terms cannabis, marijuana, and hemp all tossed around in relation to CBD. The plant Cannabis sativa has two primary species, hemp and marijuana. Both contain CBD, but there's a much higher percentage in hemp, which also has very low (less than 0.3%) levels of THC compared to marijuana.
When people talk about hemp oil, they're referring to oil extracted from the seeds of the hemp plant. There are no cannabinoids—CBD or THC—in hemp oil. This ingredient is packed with healthy fats and often appears in beauty products for its moisturizing benefits.
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. But 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."
