are e cigarettes harmful to your lungs
E-cigarettes contain some toxic chemicals and are not a safe alternative to smoking tobacco, US research suggests. In experiments on mice, scientists found that e-cigarette vapour could harm the lungs and make them more susceptible to respiratory infections. The PLOS One study also found traces of free radical toxins similar to those found in cigarette smoke.
Chemicals in e-cigarettes can damage lung tissue, provoking inflammation. That damage can reduce the ability of the lungs to keep out germs and other harmful substances, new studies show. Yet teens seem largely unaware of â or unconcerned by â the emerging data on these risks.
