E-cigarettes generate toxic chemicals similar to those found in tobacco and may harm the lungs and immune system, new research suggests.
The findings, from a study of mice, indicate that “vaping” is far from being a safe alternative to smoking tobacco.
In the experiments, mice exposed to e-cigarette fumes suffered mild damage to their lungs and became far more susceptible to respiratory infections.
Their immune responses to both viruses and bacteria were weakened by such an extent that some animals died.
