The study found that: "Neither a brief session of active e-cigarette smoking (indicative: 3% reduction in FEV1/FVC) nor a 1 h passive e-cigarette smoking (indicative: 2.3% reduction in FEV1/FVC) significantly affected the lung function (p > 0.001). In contrast, active (indicative: 7.2% reduction in FEV1/FVC; p < 0.001) but not passive (indicative: 3.4% reduction in FEV1/FVC; p = 0.005) tobacco cigarette smoking undermined lung function."

When a meeting was confirmed for December 20, 2013, Nicoventures (wholly owned by BAT) wrote again, claiming it was motivated by wanting to help make smokers healthier.

"This is currently not the situation."

Dr. Glantz is simply wrong. There is abundant evidence which demonstrates that while vaping does cause some degree of respiratory irritation (and probably triggers a bit of inflammation), it is far safer than smoking and has far less of an effect on lung function.
