Despite strong evidence that vaping is much safer than smoking, that e-cigarettes do not contain any tobacco or involve any combustion, that tens of thousands of smokers are successfully using these products to quit smoking or cut down substantially on the amount they smoke, and that smokers with obstructive lung disease who switch to electronic cigarettes experience and immediate improvement in their respiratory symptoms, it appears that the American College of Chest Physicians and its partner organizations in FIRS would rather see tens of thousands of vapers return to cigarette smoking than to maintain a much healthier, smoke-free or greatly smoke-reduced lifestyle.

Regardless of where you stand on these separate debates, the fact that in less than a decade electronic cigarettes have become one of the “big players” in shifting state and federal legislation, shows just how important electronic cigarettes are to changing the smokers market now as well as in the future.

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."
