CBD—the abbreviation for cannabidiol, a substance that’s generally derived from the hemp plant—has skyrocketed in popularity over the last five years. In fact, according to some research, “CBD” as a Google search term remained stable from 2004 to 2014 but has since ballooned by up to 605%.

It’s important to point out that CBD is not regulated by the FDA and therefore dosages might not be accurate. It’s also difficult to know what an appropriate dose is the first time you try a new product.
Can Interact With Other Medications
“Since discovering the endocannabinoid system (ECS) in the body in the 1990s, CBD has been researched more extensively. The ECS is a central regulatory system restoring normal balance and homeostasis in a range of human physiologic systems throughout the body and brain and has cannabinoid receptors and chemicals in its function,” explains Dr. Matharu-Daley.
Also known as “cotton mouth,” CBD can potentially cause your mouth and eyes to feel very dry, notes Dr. Brent A. Bauer via Mayo Clinic. Though this side effect is more likely to occur with THC, it can happen with CBD, as well.
CBD is technically an unregulated substance in the United States and therefore it ought to be used with caution. This is especially important for those taking additional medications and/or those with ongoing medical issues. That said, preliminary research on CBD and its benefits are promising in relation to helping with mild to moderate health concerns and it is generally considered a safe substance. Health professionals do not consider CBD a cure-all for serious medical issues, including cancer.
She adds, “[Another difference is that] CBD is derived from hemp and has been classified as a legal substance. Hemp has <0.3% THC. Conversely, cannabis plants such as marijuana are grown to have much higher levels of THC and are still illegal according to the FDA, although individual states vary as to their use.”
So we thought we’d compile all the negative scientific evidence into one handy guide, to help you decide whether CBD is right for you. We’ll cover the different side effects you might encounter and what they could mean, as well as what current research says about trying CBD if you are:
These trials will double the number of preexisting clinical trials that have been carried out for cannabidiol, and it’s just the beginning. Will some of the promising benefits of CBD prove wrong when tested clinically? Most likely. People are currently trying to treat countless conditions with CBD, and it’s likely that a few of them might not be any more effective than placebo when tested with clinical trials.

Side effects based on high-dose clinical trials
Although CBD might be a new molecule to you, scientists have been studying it since the 1970’s, alongside its infamous sister molecule, THC. For the past few decades, lawyers, doctors, patients and politicians have all been pitting the medical potential of cannabis against its risk for recreational abuse. But all the while, evidence has been mounting that CBD offers similar — if not better — medical benefits without the downside of a “high” from THC.
