Just a laymans thought on this. E-cigs are marketed as those devices that are pre packaged, with pre filled atomisers that you see advertised in the press and for sale at the kiosk/tobacco counter of your local supermarket. They look like a traditional cigarette and are intended to keep that purchaser buying that same brand of e-cigarette, much like the tobacco companies do with their product. Now anyone with a suspicious mind must already get where I am heading with this, with regard to THOSE SPECIFIC E-CIGS. It may actually be the case that the manufacturers are putting additives into the atomisers, other than the ingredients we, as vapers, use, simply to promote addiction. I have always thought that there should be a definite division and difference between e-cigs and 'personal vapourisers'. That is just my two penneth and I know I do not need to elaborate for you all to get my drift.
