Teenagers are more likely to get bronchitis if they use e-cigarettes, according to a new study.

The study by University of Southern California found that those who vape have a 71 percent higher risk of the condition, which risks damaging the lungs.
Researchers analyzed study responses from more than 2,000 older teenagers, asking for symptoms of chronic bronchitis, such as a daily cough for three months straight.
They found those who currently used e-cigarettes were 85 percent more likely to have had the lung infection – or 71 per cent when those who smoked regular cigarettes or were exposed to tobacco smoke were taken into account.
Dr Rob McConnell, professor of preventive medicine at the Keck School of Medicine, within the University of Southern California, said:”‘E-cigarettes are known to deliver chemicals toxic to the lungs, including oxidant metals, glycerol vapor, diketone flavoring compounds and nicotine.
“However, there has been little study of the chronic health effects of e-cigarettes.
“The Children’s Health Study provided an opportunity to examine bronchitic symptoms common among smokers to see if the risk was also increased in users of e-cigarettes.”
This comes after separate researchers found formaldehyde in e-cigarette flavorings.
The latest research, published in the American Journal of Respiratory and Critical Care, is authoritative because it adjusts findings based on cigarette smoke to ensure the effect of only e-cigarette vapor is shown in the results.
But it is based on self-reported questionnaires of bronchitis symptoms.
In the UK, young people under 18 are banned from buying e-cigarettes.
Dr. McConnell said: “Our results suggest that these regulations and an environment that discourages the initiation of any tobacco product may reduce the burden of chronic respiratory symptoms in youth. However, because e-cigarettes are relatively new, additional study is needed to fully understand their long-term effects.”
