E-cigarette vapour is much less harmful to lung cells than cigarette smoke. Lab tests show that, unlike tobacco smoke, which causes oxidative stress and cell death, e-cigarette vapour does not. Oxidative stress and cell death are driving factors in the development of many smoking-related diseases such as COPD and lung cancer. Vapour from e-cigarettes has…
