A study has found that the fumes and sweet, tasty chemicals found in e-cigarettes are capable of causing harm to the lungs, with some unfortunate test mice suffering from damaged airways and showing an increase in respiratory infections.
The immune systems of the poor mice were so weakened by chemicals that some simply gave up and died, with the vape fumes found to contain the same dangerous "free radical" compounds that exists in pollution and last-gen fire-based cigarettes.
Professor Shyam Biswai, from the John Hopkins University in Baltimore, said: "Our findings suggest that e-cigarettes are not neutral in terms of the effects on the lungs. We have observed that they increase the susceptibility to respiratory infections in the mouse models." [Sky News]
