Study finds e-cigarettes may harm users’ lungs

If you’re relying on electronic cigarettes (or e-cigarettes) as a safer alternative to smoking, a new study finds they may still be causing harm to your lungs.

E-cigarettes, which release a vaporised dose of liquid nicotine without smoke or tobacco, have been stirring up hot debate over their safety, with some experts urging that they be pulled from the shelves.

As part of the latest study, researchers from the University of Athens recruited eight people who had never smoked and 24 smokers, 11 with normal lung function and 13 with either asthma or chronic obstructive pulmonary disease.
