From wikipedia:
So to sum:
1. All e-juices/e-cigs aren't free from cancer causing agents.
2. "Nicotine free" e-juices can have nicotine.
3. Nicotine levels might be random and not what is advertised.
There's more and more brands and manufacturers coming to the business and you never know for sure what you inhale.
The thing that bugs me most is that I'm planning to buy nicotine free e-cigs for weekend use, but now it looks that I might end up inhaling nicotine juice after all
I hope that there will be some big e-juice manufacturers in Europe in the future whose e-juices are fully tested and don't include any surprises. China stuff scares me a bit.
In May 2009, the Food and Drug Administration (USFDA) Division of Pharmaceutical Analysis tested the contents of 19 varieties of electronic cigarette cartridges produced by two vendors (njoy and Smoking Everywhere)http://en.wikipedia.org/wiki/Electronic_cigarette#cite_note-Zezima-6. Diethylene glycol was detected in one of the cartridges manufactured by Smoking Everywhere. In addition, tobacco-specific nitrosamines (TSNAs), known cancer-causing agents, were detected in all of the cartridges from one brand and two of the cartridges from the other brand. The study found that the actual nicotine levels did not always correspond to the amount of nicotine the cartridges purported to contain. The analysis found traces of nicotine in some cartridges that claimed to be nicotine-free.
