“Second hand mist from an e-cigarette is not smoke at all, and does not contain any substance known to cause death, short or long term, in the quantities found. It becomes invisible within a few seconds, and is not detectable by smell.


Exhaled breath after e-cigarette use has been tested for CO only. No increase in CO was found.
The e-cigarette does not create side-stream smoke.


Exhaled breath after e-smoking contains even less nicotine per puff, as much of the nicotine inhaled is absorbed. Similarly, propylene glycol is largely absorbed and little is exhaled. 

No harm found in e-cigarette mist”

Raman Minhas, technical officer of WHO’s Tobacco Free Initiative, says, “Dr. Laugesen is a respected tobacco control researcher.” (http://www.newscientist.com/article/mg20126951.700-electronic-cigarettes-a-safe-substitute.html)

 

“All that's happening is you're heating up a liquid to the point of becoming a vapor. So referring to it as smoke doesn't make sense at all. Therefore, considering it subject to a smoking ban doesn't really make sense, either.”

“As one who experiences severe headaches, sneezing, watery eyes and other sinus problems from exposure to very little secondhand tobacco smoke (a key reason I’ve been an outspoken smokefree indoor policy/law activist since 1986), I’m delighted and relieved to report that I experienced NO adverse reactions during or after my mega exposure to e-cigarette vapor.”

—  William T. Godshall, Executive Director, Smokefree Pennsylvania, from a report on attending a conference for electronic cigarette consumers

 

 “There is no existing evidence that e-cigarettes pose a risk for nonsmokers. The nicotine exposure from the exhaled vapor produced is likely to be extremely small and there is no reason to think that it poses a danger for nonsmokers. But there is certainly no evidence to suggest that it poses a hazard.”

—   Dr. Michael Siegel, Professor of Social and Behavioral Sciences, Boston University School of Public Health, who also has 20 years of experience in Tobacco Control (TobaccoAnalysis.blogspot.com)

 

“The claim that the trivial amount of vapor would be much of a risk seems ridiculously far-fetched.”

—   Dr. Carl Phillips, TobaccoHarmReduction.org



“There is substantial and compelling scientific research documenting that consuming the ingredients in e-cigarettes (nicotine, propylene glycol, water and flavors) is vastly safer than burning tobacco and inhaling 3000+ toxic by-products. Claiming that e-cigarettes are dangerous for non-smokers is about as credible as claiming that air travel is dangerous for people who never set foot in an airplane.”
