Glantz Asserts that Pulmonary Effects of Smoking May Be No Worse than those of Vaping

This study documents that while active smoking has immediate, clinically meaningful effects in reducing lung function, electronic cigarettes do not. 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."The main study finding was as follows: "The assessment of lung function demonstrated that neither a brief session of active e-cigarette smoking nor a 1 hour passive e-cigarette smoking session significantly interfered with normal lung function. On the other hand, acute active and passive tobacco cigarette smoking undermined lung function, as repeatedly shown in previous studies." The study concluded that: "e-cigarettes generate smaller changes in lung function but similar nicotinergic impact to tobacco cigarettes."In order to draw the conclusion that Dr. Glantz drew in his comment, one would have to completely ignore this study. Obviously, Dr. Glantz has done exactly that. He has based his comment on one narrow study and ignored the rest of the literature.But it doesn't end there.The Marini study demonstrates that electronic cigarettes do lead to a reduction in ...
