Cannabidiol is a controversial treatment because it is one of the components of marijuana, a widely known recreational drug. There are strong opinions about the drug, and proponents advocate for its legalization for medical uses, while some advocate for the legalization of recreational use as well.
A 2017 study published in JAMA found that 26 percent of products purchased online contained less CBD than their labels claimed.

If you have questions regarding whether cannabidiol is an appropriate treatment for you or someone you know, talk to your healthcare provider first. You can use our Doctor Discussion Guide below to help start that conversation about treatment options and more.

It’s possible that CBD may raise the blood level of certain other anticonvulsants such as Topamax and Onfi (clobazam), and may result in side effects.
The short answer is yes. CBD can help prevent some types of seizures in some people and animals. Clinical trials have demonstrated a significant reduction in seizures for people taking CBD to treat Lennox-Gastaut, Dravet syndrome, or tuberous sclerosis complex. Research in other areas is still in early stages, but there are indications that CBD may help prevent other types of seizure or increase the efficacy of other antiepileptic medications. Early clinical trials suggest that CBD may dramatically reduce seizures in people with CDKL5 deficiency disorder, Aicardi syndrome, Doose syndrome, and Dup15q syndrome. In addition, CBD appeared to retain its efficacy over the length of the clinical trial.
Does CBD help seizures?
Yes, but not all CBD oils and not all types of seizures. Currently, Epidolex, a prescription form of CBD, is approved to treat seizures caused by Lennox-Gastaut, Dravet syndrome, and tuberous sclerosis complex.
Is CBD approved by the FDA to treat seizures?
Studying neuroscience is challenging. While scientists can take a hands-on approach to discover how other…
For many who have used CBD oil, the newly available treatment has provided relief when all else failed. About two thirds of epilepsy patients will respond to the first or second medicine they’re given for epilepsy. But once an epilepsy patient has taken two different medicines without relief, the odds that a third medication will work are less than 1 percent, doctors say. That leaves other options, such as special diets, surgeries, device implementation—or CBD oil.
Despite taking a slew of medications, and despite having a device implanted under the skin of his chest that sends electrical impulses to his brain to reduce the number and severity of his seizures, Trysten’s symptoms persisted.
He often felt nauseous and he’d vomit every few days. Because exercise triggered his seizures, his school stopped allowing him to participate in physical education, leading to weight gain. His grades were dropping and his memory was fading, too.
“I really wanted this medicine to work because of how many times pills have failed me,” said Trysten, who takes drops of the oil orally. “Once I started taking it, I felt so much better. I don’t have seizures.”
Under the state’s compassionate use law, patients’ medicine must contain at least 10 percent CBD oil and no more than 0.5 percent THC. For context, recreational marijuana might measure 20 percent THC. Those restrictions ensure Texas CBD oil makers maximize the compounds that provide symptom relief while minimizing those that can cause side effects or a high (Trysten Pearson, for his part, said he experiences no side effects from CBD oil).
They were astounded by how quickly, and how well, the treatment worked.
For the Pearsons, cannabis was a last resort to relieve Trysten’s epilepsy after years of other treatments failed to provide relief.
