US regulators said Wednesday they are investigating reports that e-cigarettes – increasingly widespread in America and elsewhere – may cause seizures.
“We have reports indicating that some people who use e-cigarettes, especially youth and young adults, are experiencing seizures following their use,” the Food and Drug Administration (FDA) said in a statement.
The FDA has reviewed “voluntary adverse event reports,” finding “a total of 35 reported cases of seizures following the use of e-cigarettes between 2010 and early 2019,” it said.
“We believe these 35 cases warrant scientific investigation into whether there is, in fact, a connection.”
The use of e-cigarettes – colloquially known as vaping – began to take off among young Americans in the 2010s, and overtook cigarette smoking in 2014.
The US categorises e-cigarettes – which deliver nicotine, often as part of fruit- or sweets-flavoured vapour – as tobacco products, a definition not shared by all countries.
