Using Cannabis for a Child With Epilepsy

Research has shown that cannabis may help ease severe epilepsy in children. British scientists discovered that medical marijuana reduced epileptic seizures in children by 90% while also reducing the need for traditional medications.

Epilepsy in Children Overview

Approximately 3.4 million people in the United States have epilepsy. Of these 3.4 million individuals, 470,000 are children.

Epilepsy often has no known cause but is sometimes believed to be triggered by:


There are several different types of childhood epilepsy, but the ones that cannabis has shown the most promise in treating are:

  • Dravet syndrome
  • Lennox-Gastaut syndrome

Both Dravet and Lennox-Gastaut are severe forms of epilepsy characterized by frequent, violent seizures. In 2018, the Food and Drug Administration (FDA) approved Epidiolex as the first natural cannabis-derived medication to treat Dravet and Lennox-Gastaut syndromes. The FDA approval was groundbreaking, as up until 2018 only synthetically-derived cannabis medications (i.e. Dronabinol for people with cancer) had been approved.

Traditional Treatments

Traditional treatments for epilepsy include the following:

  • Seizure-reducing prescription medications like valproic acid
  • Nutritional therapy
  • Vagus nerve stimulation (VNS)

Prescription medications for epilepsy usually come with numerous side effects, such as stomach pain, nausea, diarrhea, headache, weight gain and thinning hair. The benefit of Epidiolex and other cannabis-based treatments is that they usually cause only mild side effects or no side effects at all.

How Medical Marijuana Helps Seizures and Epilepsy in Kids

Cannabis and CBD may help some children with epilepsy, especially treatment-resistant epilepsy. CBD’s efficacy derives from the distinct differences between CBD and THC (delta-9-tetrahydrocannabinol).

THC typically affects several of the body’s receptors and impacts our sense of pain, anxiety levels and memory, as well as affecting perception, learning and motor control. CBD, however,  does not interact in the same way with our body as THC, and does not interact with CB1 or CB2 receptors in the same way. When taken together, CBD can even dampen many of the effects THC has on the user, or elongate THC’s effects at the same time as blunting them.

CBD’s ability to inhibit the effects of THC seems to be related to CBD’s ability to inhibit seizures.

Multiple factors go into current theories for why CBD and medical marijuana effectively reduce the severity of intractable childhood seizure conditions.The experts aren’t precisely sure why CBD reduces convulsions in so many children suffering from chronic seizure conditions. However, Dr. Ben-Zeev of Sheba Medical Center in Israel, is certain that:

  1. A Facebook group of 150 parents reported an 84% reduction in seizure frequency after using CBD extracts to treat their children; 11% became seizure-free.
  2. In another online survey, 117 parents of children with epilepsy using CBD extract reported 85% responders, with 14% of the children achieving seizure freedom.
  3. A survey from Mexico tracked 53 patients aged 9 months to 18 years, reporting 83% of patients experienced improved seizure control, and 16% became seizure-free while using cannabis extract compounds.
  4. Based on parental reports and a medical chart review, one-third of 75 children and adolescents with Lennox–Gastaut syndrome and Dravet syndrome who received doses of oral cannabis extracts experienced more than a 50% reduction of seizures.
  5. A multicenter retrospective study from three epilepsy clinics in Israel treating 74 children for intractable epilepsy found that 52% of patients experienced more than 50% reduction in seizure frequency.
  6. A chart review on the effect of “artisanal” cannabis on 272 pediatric epilepsy patients from Washington and California noted a more than 50% reduction in seizure frequency in 45% of patients, with 10% becoming seizure-free.

Using Cannabis for Epilepsy in Children

There are several possible cannabis treatment options for children with epilepsy, including prescription medications, CBD products and medical marijuana strains.


Currently, Epidiolex is the only FDA-approved cannabis medication for childhood epilepsy. Unlike over-the-counter CBD products, most health insurance companies cover Epidiolex, which is an important benefit for many people as the drug can cost more than $32,000 annually out-of-pocket.

Not only can CBD-based medical cannabis treatment be used to treat children and adolescents with intractable epilepsy, but that use has happened for decades already.

In January 2020, the U.S. National Library of Medicine published an article titled “Medical Cannabis for Intractable Epilepsy in Childhood: A Review.” The entry provides an overview of studies conducted during the previous six years into the efficacy of using medical cannabis products to relieve the symptoms of intractable childhood seizure disorders.

The National Library of Medicine author Bruria Ben-Zeev, MD, a specialist in pediatric neurology, notes a long history of study, predating the discovery and isolation of CBD, that documents cannabis used as an epilepsy therapy.

Dr. Ben-Zeev also links Chinese historical records from 2700 BC and Sumerian and Akkadian tablets inscribed in 1800 BC to 19th century papers published by leading physicians of the day, all extolling the virtues of cannabis as an anticonvulsant.

Medical Strains

Dr. Ben-Zeev finds that studies of medical strains and THC’s effect on seizures have had mixed results, including THC triggering proconvulsant responses, “making it less attractive for clinical epilepsy treatment.”

According to a report from CBD Project, a non-intoxicating cannabinoid found in raw and live cannabis called THCA shows great promise in treating epilepsy. One presumed benefit of THCA is that lower doses would be required compared to other cannabis-derived epilepsy treatments. However, THCA research is at the preclinical stage, and though there is insufficient scientific data to recommend it as a current treatment, anecdotal experiences mark THCA as a treatment to watch in the future.
