Like many positive studies about vaping, this one ALSO has been distorted beyond recognition by the press.
AFAIK, there was a *range* of voltages tested. Not just 5+ volts.
On the voltage range normal people would use a modest cartomizer (starting at around 3v), no "carcinogenics" were found.
After an increase of voltage, things that were not supposed to be there started to appear. Of course, if you apply 5v+ on a cartomizer, with much less liquid drainage than a RTA, the coil will dry and eventually burn. The pump used in the study did not cough or complain. If they gave that device for a vaper to try, they would understand that *no-one* could possibly use that cartomizer at 5 volts.
All the study has shown is that there are nasty things on *dry-puff* conditions. I already knew it, thankyouverymuch. There's no need for a fancy study to tell me that - I can taste and smell things, now that I have quit smoking for more than six years.
Of course, the media reported *all* e-cigs being as dangerous as if they were really used *always* in dry-puff conditions. And as if it was possible for *anyone* to use e-cigs in those conditions, without realizing that something was wrong, as if a dry-puff tasted just as good as your best premium e-liquid.
