– Dr. Farsalinos and Scientific Data Regarding Levels of Aldehydes in Vapor

E-cigarettes generate high levels of aldehydes only in “dry puff” conditions (irrespective of the power levels)

Finally!  Some real information and scientific evidence (and by that I mean research that has been done and peer reviewed).  When an earlier study done earlier in 2015 by the New England Journal of Medicine showed that there were levels of formaldehyde in the e-liquid vapor at specific conditions, I was immediately skeptical.  Considering there are only a few ingredients typically used in the production of e-liquid (propelene glycol, vegatable glycerin, nicotine liquid which isn’t used in 0mg liquids, and a combination of flavorings), most people should be able to reasonably conclude that there really isn’t anything harmful in the vapor emitted.

Dr. Farsalinos helped proved my own thoughts on this.  The original study had a couple startling issues.  First, they used older style refillable tanks that aren’t typically used much in the industry.  They are pretty limited to older “starter kits” and cheaper brands that keep to the eGo style devices.  While this alone isn’t too concerning, how they tested the devices was.

The NEJM specifically ran the devices and tanks at such a high voltage that the coils were running in what’s called a dry puff or dry hit condition.  This happens when the liquid isn’t being fed fast enough to the wick and coil inside the tank.  Any vaper within the first week knows what this is, how to prevent it, and what it tastes like.  And no vaper will willfully run their device to this point, especially for extended amounts of time (something the original testing did as well).  At this point of the test, the study was most likely burning the wicks inside the tank and the flavor alone would be nearly impossible to get rid of and warrant a replacement coil (or entire tank if it’s considered disposable).

The new study used a much newer set of tanks, the popular Kayfun Lite.  This tank is made specifically for vapers who want to get the best flavor out of their liquid and be able to go through a good amount of liquid before having to be refilled.  It is only rebuildable as there is no option for prebuilt coils like many other tanks on the market.  The study also ran the tests at much more reasonable power levels from 6w to 10w (again, typical for this type of tank) and for a more reasonable

The study showed that at at reasonable and usable power levels plus a more typical vaporization time that there was minimal aldehyde levels in the vapor.  Compared to standard cigarettes, the levels were 30 to 250 times lower.  Let me be clear on that.  30 to 250 times LOWER than a standard cigarette.

At this point, a large reduction in these aldehyde levels show how much safer e-liquid vapor can be.  Obviously, more studies need to be done but this is a very good sign at proving scientifically that vaping is a much healthier alternative to smoking.
