Prior to this study, the most significant health concern regarding passive vaping was the possibility of exposure to carcinogenic and toxic aldehydes and pyrolysis products including formaldehyde, acrolein, and acetone. However, this study found no increase in concentrations of any of these pollutants under realistic (real-life) conditions.

What the story demonstrates is that Dr. Glantz has a pre-determined set of conclusions about electronic cigarettes and the tobacco companies' role in inappropriately marketing these products to addict a new generation of kids. When presented with information, he jumps to an immediate interpretation and conclusion that supports his pre-determined schema. Instead of exercising critical judgment and objective evaluation of the evidence, he immediately twists the facts to support his pre-existing position. Dr. Glantz is just one example of a phenomenon that characterizes a number of researchers and tobacco control groups that are vehement opponents of electronic cigarettes for ideological, rather than valid scientific reasons.

"While we have heard from former smokers who say e-cigarettes helped them quit, we have to ignore their statements because we just can't bring ourselves to admit that something which looks like a cigarette could possibly be a good thing and could have positive benefits like helping a smoker get off of tobacco cigarettes."

Instead, the study examines the percentage of quitting among all smokers who have ever tried electronic cigarettes - for any reason - in the past month.
