There was also a 10% and 44% increase, respectively, in the risk of coronary artery disease and circulatory problems, including blood clots.
"… These data are a real wake-up call and should spur more action and awareness about the dangers of electronic cigarettes," said lead author Mohinder Vindhyal, an assistant professor at the university. .
"Regardless of how often people use electronic cigarettes every day or every day, they are always more likely to have a heart attack or coronary heart disease," Vindhyal added.
