FDA evaluation of e-cigarettes
Read the Study (Or the Summary)
The FDA analyzed the contents of 18 e-cigs from two different brands. They were looking for carcinogens called nitrosamines and other contaminants.
What It Found
There were low levels of nitrosamines in five of these products. One of them also contained 1 percent diethylene glycol – an ingredient in antifreeze.
The study was conducted in 2009, but people are still citing it.
What’s Wrong With it?
In the six years since this study was released, there have been many, many similar studies. Diethylene glycol has never been detected again. Since it was only found in one sample (at a low concentration) it can hardly be treated as a common problem in e-liquid.
It’s also an ingredient added to cigarettes. Finally, even if the levels found by the FDA were present in every e-cigarette, it probably still wouldn’t be a major health concern.
