Scientific Study Proves Second-Hand Vapor is Not Harmful

A study titled “A rapid method for the chromatographic analysis of volatile organic compounds in exhaled breath of tobacco cigarette and electronic cigarette smokers” was performed by The Spanish Council of Scientific Research and published on Monday September 7th, 2015 in the Journal of Chromatography A.

Levels of several volatile organic compounds (VOC) were measured in indoor air, normal exhaled breath, smoke of tobacco cigarettes, exhaled breath of smokers after taking cigarette puffs, e-cigarette aerosol and exhaled breath of vapers after taking e-cigarette puffs.



The results of the study shown in the chart below (nd = not detected) indicate that e-cigarette aerosol alone contains less volatile organic compounds (VOC) than normal exhaled breath as well as normal indoor air.

Second hand vapor, or “Exhaled Breath” as referred to in the study, show that the volatile organic compounds are equal to or less than normal exhaled breath.

The amount of VOC’s in second hand vapor is so low that Dr. Konstantinos Farsalinos ,cardiologist and avid e-cigarette and vaping researcher, was quoted as saying “I calculated 17 and 25 VOCs in the 2 e-cigarettes tested, 36 VOCs in indoor air and 42 in normal (non-smoking, non-vaping) exhaled breath. Tobacco cigarette smoke contained 86 VOCs, and exhaled breath after smoking similarly contained a large number of VOCs. As I said, not all VOCs are toxic but, interestingly, there were cases of toxic compounds present in the exhaled breath but not in the e-cigarette aerosol. For example, isoprene, which is listed as a carcinogenic compound in California Proposition 65 (I hope the CEH is reading this comment), is present ONLY in exhaled breath (even in normal exhaled breath), but not in e-cigarette aerosol.”

Will this be the study that finally makes lawmakers and politicians’ realize that second hand vapor is not harmful?  Let us know in the comments section below!
