"In terms of acute effects on respiratory function, active smoking is exactly equivalent to the effects of taking a math test."

The main difference between this study and those touted by Glantz as showing that e-cigarettes are ineffective is that unlike Glantz's cited studies, this one actually examines cessation rates among smokers who reported using e-cigarettes for smoking cessation. In other words, Brown et al. included smokers who reported having used e-cigarettes with the intention to quit smoking. In the studies cited by Glantz, smoking cessation rates for all e-cigarette users were examined, even if a smoker just tried a puff of an electronic cigarette to see what all the hype is about.

I believe that this story reveals the venom that many e-cigarette opponents have for the act of smoking and anything that looks like it. And that ideological venom is what is keeping them from forming opinions based on the actual scientific evidence. Professor Ashton's apparent hatred for vapers can only be rooted in an ideology that despises the physical act of smoking, regardless of whether what is being "smoked" contains tobacco or not or whether the behavior is killing the person or perhaps saving his life. In other words, this is a great example to demonstrate the way in which ideology, not science or public health, guides the opinions and statements of many electronic cigarette opponents.

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.
