A team of researchers from the University of Southern California finds that teenage users of e-cigarettes are twice more likely to get bronchitis compared to children who have never smoked electronic cigarettes.

For their study, the scientists analyzed the responses from more than 2,000 older teenagers, asking for symptoms of chronic bronchitis such as a daily cough for three months straight.

Researchers found that those teenagers who vape had 71% higher risk of the condition which was connected to the risk of damaging lungs.

Dr Rob McConnell, a professor of preventive medicine at the Keck School of Medicine, within the University of Southern California, says: “E-cigarettes are known to deliver chemicals toxic to the lungs, including oxidant metals, glycerol vapour, diketone flavouring compounds and nicotine. However, there has been little study of the chronic health effects of e-cigarettes.”
