ScienceDirect – Cigarette/Electronic Cigarette/Air Study

ScienceDirect – Comparison of select analytes in aerosol from e-cigarettes with smoke from conventional cigarettes and with ambient air

Disclaimer: The link above is a scientific article describing in detail testing procedures and methods of comparing standard cigarettes, multiple electronic cigarettes, and standard air.  Much of the article is outside my higher learning background but I will do my best to explain some of the details and conclusions brought forth in the research.

Some more research has come forward that shows very positively that electronic cigarettes are an order of magnitude healthier compared to regular ol’ cigarettes and shows data that the second-hand vapor is comparable to regular air that anyone would breathe.

For the testing procedures, the scientists analyzed the liquid component of 5 different electronic cigarette “cigalikes” and 3 different cigarettes of varying brands.  Multiple nicotine levels were also used in the sample set.  An analysis of the eliquid showed varying levels of glycerin and propylene glycol, water, nicotine, and flavoring.  ‘

For the actual vapor and smoke portion, 7-9 puffs of cigarettes were used and 99 puffs of electronic cigarettes were utilized (approximately 11x the puffs in comparison).  I’ve always been under the impression that one cigarette puff was closer to 5 puffs of an electronic cigarette.  I’ll probably be revising this for the future.

The study shows that a standard electronic cigarette test of 90-99 puffs yielded between 50-900x less measurable HPHC’s (harmful and potentially harmful constituents) in 5 cases.  Phenol was measured 900 times lower in one case.  N-Nitrosoanatabine in 1 product was 50 times lower.  Lastly, 3 carbonyls were measured at 86-544 times lower.  The other 50 measured HPHC’s were measured in so low quantities (if at all) that they would not be quantifiably significant compared to the standard air tested.

So what does this mean?  The scientists who conducted this test concluded that electronic cigarettes measured similarly to the air tested.  Furthermore, electronic cigarette vapor provides “markedly reduced exposure to hazardous and potentially harmful smoke constituents in smokers who use such products as an alternative to cigarettes.”

While this study is one of many, it is yet another piece of SCIENTIFIC evidence that electronic cigarettes are significantly less harmful than cigarettes and potentially extremely safe around the general population.  I highly encourage you to read this study to see how the test was done and how the different HPHC levels compared through the numbers.
