E-cigarette vapor contains nicotine, NOT other toxins

Here is an interesting article posted on the Reuters website.

Thanks for sharing. Reuters is big !

Hmm...

"What we found is that non-users of e-cigarettes might be exposed to nicotine but not to many toxicants when they are in close proximity to e-cigarette users," said Goniewicz.

"It is currently very hard to predict what would be the health impact of such exposure," he added.

Really?

I'm still curious about tobacco flavors and how many alkaloids etc... are steeped out of tobacco and transfered through vapor. I'm sure the fact that those chemicals aren't combusted is a positive. But, I'm also not sure how legitimate my claim of being tobacco free is when the primary flavor I vape is derived from tobacco. I mention this because the methodology in the study cited makes no mention of what flavor, if any, was used in the test. Only that it used three different brands.

It should be fairly easy to predict the effect that inhaling 3.3 mcg per meter of nicotine might have on a bystander.

3.3 micrograms per meter converts to 0.00265397 parts per million

When pigs were fed food containing 1,884 times more nicotine, their weight decreased.

A level of 5 p.p.m. of nicotine sulfate in the ration fed to pigs from weaning until market weight significantly decreased (P<.05) the depth of loin fat in two of three experiments in which it was tested and slightly increased the carcass protein: fat ratio in all experiments. A level of 20 p.p.m. was as effective as 5 p.p.m. but higher levels of 40 and 80 p.p.m. had no effect on carcass quality. The fat content of the livers of pigs fed 5 p.p.m. of nicotine sulfate was found to be 8 to 10 per cent higher than that of controls in the two experiments in which it was measured. Higher levels of nicotine had little or no effect on liver lipids. Plasma cholesterol levels of pigs were not increased by the feeding of nicotine sulfate at levels of 5, 20 and 80 p.p.m. Further Studies on the Use of Nicotine to Promote Leanness in Pigs

But that was oral ingestion. What about inhalation?

Abstract

Tobacco smoking has been reported to be associated with increased risk of cardiovascular disease and cancer, particularly of the lungs. In spite of extensive research on the health effects of tobacco smoking, the substances in tobacco smoke exerting these negative health effects are not completely known. Nicotine is the substance giving the subjective pleasure of smoking as well as inducing addiction. For the first time we report the effect on the rat of long-term (two years) inhalation of nicotine. The rats breathed in a chamber with nicotine at a concentration giving twice the plasma concentration found in heavy smokers. Nicotine was given for 20 h a day, five days a week during a two-year period. We could not find any increase in mortality, in atherosclerosis or frequency of tumors in these rats compared with controls. Particularly, there was no microscopic or macroscopic lung tumors nor any increase in pulmonary neuroendocrine cells. Throughout the study, however, the body weight of the nicotine exposed rats was reduced as compared with controls. In conclusion, our study does not indicate any harmful effect of nicotine when given in its pure form by inhalation.

Based on this information, my prediction is that inhaling someone's exhaled vapor containing 3.3 micrograms per meter (0.00265397 parts per million) of nicotine would have no observable or measurable effect whatsoever.

Outstanding argument, Vocalek. All I'd add is Q.E.D.
