The Food and Drug Administration is investigating dozens of reports of people who experienced seizures after using e-cigarettes.

The agency announced Wednesday that it has received 35 reports of people suffering seizures after vaping between 2010 and 2019. Most of those cases were in adolescents and young adults. And while it isn’t clear whether there is a direct link between e-cigarettes and the seizures, health officials said they found the reports troubling.

“While 35 cases may not seem like much compared to the total number of people using e-cigarettes, we are nonetheless concerned by these reported cases,” FDA Commissioner Scott Gottlieb and Principal Deputy Commissioner Amy Abernethy said in a statement.


Convulsions and seizures are known to be a potential side effect of nicotine poisoning, according to the FDA. The agency said it’s possible that some e-cigarette products make it possible for people to inhale a significant amount of nicotine quickly. E-cigarette users also might be inadvertently or deliberately inhaling more nicotine than normal. But the FDA said it’s also possible that other factors were behind the seizures.

“We want to be clear that we don’t yet know if there’s a direct relationship between the use of e-cigarettes and a risk of seizure. We can’t yet say for certain that e-cigarettes are causing these seizures,” Gottlieb and Abernethy said.

So far, the agency has not been able to establish a clear pattern among the reported cases. Some of the seizures were among first-time vapers, and others were among people who frequently used e-cigarettes. The seizures didn’t occur at the same point in time after vaping — some happened after a few puffs, and others up to a day after using an e-cigarette. The FDA said there also wasn’t enough data in many of the reports to identify the brand or sub-brand of e-cigarette that a person had used.

A few of the cases also occurred in people who had a history of seizures or who were also using marijuana or amphetamines.

Health officials are urging people who experience any health issues after using an e-cigarette to report the problem to a federal safety reporting portal. The FDA said more data might help the agency determine whether there is a link between seizures and vaping and if so, whether there are any common risk factors or e-cigarette designs that might be involved.

  • This issue is HUGE! The liquid in e-cigarettes is composed of more than 95% propylene glycol and/or glycerol. Both of those were classified as GRAS (Generally Recognized As Safe) by the FDA itself many years ago. Today those things can be found in our foods, cosmetics and other common products. The remaining 5% or less of e-liquid is common food flavouring and/or nicotine. No component in e-cigarette liquids should be causing seizures but if one or more of them are then the FDA should ban all use of propylene glycol, glycerine, food flavourings and nicotine immediately. If not sooner.
