Lung-in-the-lab reveals no DNA damage on exposure to e-cig vapor

(R&D at British American Tobacco) E-cigarette vapor does not damage DNA, even at doses 28 times that of equivalent smoke exposure.Scientists at British American Tobacco used lab-based cellular tests to examine the impact of cigarette smoke and Vype e-cigarette vapor on human lung cells. The most serious kind of DNA damage is double-strand break, which effectively means that both strands of the DNA molecule have been broken. This is a possible precursor to cancer and potentially lethal to the cell.
