Scientists Uncover Worrying Link Between Frequent Cannabis Use and Seizures
Researchers at the Washington University School of Medicine have identified a potential link between frequent cannabis use and the worsening of seizures in patients with treatment-resistant epilepsy. The study suggests that cannabis users experienced faster progression of severe epilepsy, prompting calls for further clinical investigation.
Why it matters
As cannabis use becomes more prevalent, understanding its impact on neurological conditions like epilepsy is critical for patient safety and medical guidance.
Cannabis has arguably become the most popular recreational drug in the U.S. in recent years—with more Americans now consuming it daily than cigarette smoking and even alcohol. Research out today highlights a possible dark side to frequent cannabis use for at least some people, however: a greater risk of worsening seizures.
Researchers at the Washington University School of Medicine in St. Louis studied people with treatment-resistant epilepsy, and found that people who reported frequent cannabis use were more likely to have severe seizures, while the progression to severe epilepsy was significantly faster in this group as well. The results, while not firm proof of a causative connection, merit more study and potential caution surrounding cannabis among those with epilepsy, the researchers say.
