The US Food and Drug Administration (FDA) said that health officials are investigating whether e-cigarettes may induce epilepsy in some users. However, the agency emphasized that it is still unclear whether e-cigarettes are responsible for this.
According to the report, the FDA is studying 35 cases of epileptic seizures among e-cigarette users, mostly young people. The FDA stated that they have concerns about this and encourage people to use the website to report related issues.
Related cases can be traced back to 2010, when the FDA Poison Control Center received relevant notifications from across the United States. Regulators stated that they have found that the number of seizures among e-cigarette users has increased since mid-2018, but it only accounts for a very small percentage of e-cigarette users.
According to reports, most e-cigarettes heat the flavored nicotine solution into inhalable vapor. Nicotine poisoning can cause seizures, convulsions, vomiting and brain injury. The FDA has warned that if infants and young children accidentally swallow nicotine solutions, it may cause fatal nicotine poisoning.
Epilepsy usually lasts a few seconds or minutes and rarely leaves long-term damage, but it is a sign of a neurological disorder and requires medical attention.
Animal experiments have found that nicotine is related to excessive brain excitement. Goniewicz, a toxicologist at a New York State Cancer Institute, said that it is now necessary to further understand which types of e-cigarettes may release nicotine concentrations that are sufficient to cause epilepsy.
American Electronic Cigarette Association spokesperson Kang Li believes that the relationship between e-cigarettes and a small number of epilepsy cases is unknown, and the FDA's statement is quite irresponsible. He said: "If millions of adult consumers of e-cigarettes have not reported any epilepsy problems in the past ten years, this is highly abnormal."
This is not the first time the FDA has proposed the health risks of e-cigarettes. Previously, the FDA had warned that e-cigarette batteries may be overheated, which may cause rare burns and explosions.
