In 2013, Tonya Taylor says, she was suicidal because her epileptic seizures kept coming even though she was taking a long list of medications.
Then a fellow patient at a Denver neurologist’s office mentioned something that gave Taylor hope: a CBD oil called Charlotte’s Web. The person told her the oil helped people with uncontrolled epilepsy. The doctor, however, would discuss it only “off the record” because cannabidiol was illegal under federal law, and he worried about his hospital losing funding, Taylor said.

The federal government has since legalized CBD, and it has become a multibillion-dollar industry. The Food and Drug Administration also has approved one cannabis-derived prescription drug, Epidiolex, for three rare seizure disorders.
But not much has changed for people with other forms of epilepsy like Taylor who want advice from their doctors about CBD. Joseph Sirven, a Florida neurologist who specializes in epilepsy, said all of his patients now ask about it. Despite the buzz around it, he and other physicians said they are reluctant to advise patients on over-the-counter CBD because they do not know what is in the bottles.
The FDA does little to regulate CBD, so trade groups admit that the marketplace includes potentially harmful products and that quality varies widely. They say pending bipartisan federal legislation would protect those who use CBD. But some consumer advocacy groups say the bills would have the opposite effect.
Caught in the middle are Taylor and other patients desperate to stop losing consciousness and having convulsions, among other symptoms of epilepsy. They must navigate the sometimes-murky CBD market without the benefit of regulations, guidance from doctors or coverage from health insurers. In short, they are “at the mercy and the trust of the grower,” said Sirven, who practices at the Mayo Clinic in Jacksonville, Fla.
Although the CBD industry is new territory for the FDA, people have used cannabis to treat epilepsy for centuries, according to a report co-written by Sirven in the journal Epilepsy & Behavior.
More than 180 years ago, Irish physician William Brooke O’Shaughnessy administered drops from a hemp tincture to an infant experiencing severe convulsions. “The child is now in the enjoyment of robust health, and has regained her natural plump and happy appearance,” O’Shaughnessy wrote at the time.
Much of the recent interest in CBD stemmed from the 2013 CNN documentary “Weed,” which featured Charlotte Figi, then 5, who had hundreds of seizures each week. With the use of CBD oil, her seizures suddenly stopped, CNN reported. After that, hundreds of families with children like Charlotte migrated to Colorado, which had legalized marijuana in 2012. Then in 2018, the federal government removed hemp from the controlled substances list, which allowed companies to ship CBD across state lines and meant families no longer needed to relocate.
CBD Products May Help People with Epilepsy Better Tolerate Anti-Seizure Medications

Artisanal (non-pharmaceutical) cannabidiol (CBD) products have become popular in recent years for their apparent therapeutic effects. CBD — a naturally occurring compound of the cannabis plant legally derived from hemp — is used widely as a naturopathic remedy for a number of health conditions, including epilepsy and seizure disorders. Now, Johns Hopkins Medicine researchers, in collaboration with the Realm of Caring Foundation and other institutions, have conducted an observational study with participant-reported data to better understand the impact these products may have on people with epilepsy.
They found that CBD may reduce the adverse effects associated with anti-seizure medications, and seems to improve other aspects of health and quality of life for patients.
“The potential of CBD products for the treatment of seizure disorders goes beyond seizure control alone,” says Ryan Vandrey, Ph.D., professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine. “In our study, we saw clinically significant improvements in anxiety, depression and sleep when patients with epilepsy initiated therapeutic use of artisanal CBD products.”
Epilepsy, one of the most common nervous system disorders affecting people of all ages, is a neurological condition characterized by recurrent seizures. Treatment for epilepsy includes anti-seizure medications and diet therapy, such as forms of the ketogenic diet. Surgery may be an alternative treatment, especially when medications or diet fail to control seizures, or if drug side effects — including dizziness, nausea, headache, fatigue, vertigo and blurred vision — are too difficult for a patient to tolerate.
Epidiolex, a pharmaceutical formulation of CBD is approved by the FDA to treat three types of rare seizure disorders (Dravet syndrome, Lennox-Gastaut syndrome and tuberous sclerosis complex), but is not approved for the many other types of epilepsy. As a result, patients with other forms of epilepsy often seek alternative forms of CBD, including those evaluated in the new study.
For their evaluation, the researchers analyzed data gathered between April 2016 and July 2020 from 418 participants — 230 women and 188 men — with 205 (49%) at least age 18 and 213 (51%) age 18 or younger. The participants included 71 adults with epilepsy who used artisanal CBD products for medicinal purposes and 209 who were caregivers of children or dependent adults to whom artisanal CBD products were given. The control group consisted of 29 adults with epilepsy who were considering the use of CBD products and 109 caregivers who were considering it for a dependent child or adult patient.
Participants completed a web-based survey that included questions regarding quality of life, anxiety and depression, and sleep. They were prompted via email to complete follow-up surveys at three-month intervals for 14 months.
Compared with the control group, artisanal CBD users reported lower epilepsy medication-related adverse effects (13% lower) and had greater psychological health satisfaction (21% greater) at the beginning of the study. They also reported lower anxiety (19% lower) and depression (17% lower).
Both adult and youth (18 years or younger) CBD users reported better quality sleep, compared with their peers in the control groups.
Caregivers of patients currently using CBD products reported significantly less burden and stress, compared with caregivers in the control group (13% less).
Importantly, 27 patients in the control group at the start of the study started using artisanal CBD products later in the study. After starting CBD, these patients reported significant improvements in physical and psychological health, as well as reductions in anxiety and depression.
Participants also were asked about possible adverse effects related to their CBD use. Among the 280 users, the majority (79%) did not report any adverse effects. The remaining reported negative factors such as drowsiness (11%), high or prohibitive product cost (4%), worsening of epilepsy symptoms (4%), concerns about legal issues (3%) and worries about problematic drug interactions (1%).
Vandrey says further research is needed to understand how these findings can best be applied to helping people with epilepsy. In the interim, he says, patients should consult with their physician before trying CBD products.
“Our hope is to do controlled clinical trials to better inform clinical decision making and identify specific formulations that are most beneficial to patients,” he says.
