Myth ?
Here is my favorite :
One prefilled cartridge will last you the equivalent of (X) cigarettes !
(YMMV)
I think that's the biggest downside to e-cigs. You can take two pack a day smokers and they may go through totally different amounts of liqui d a day so it's harder starting out to know how much you will need.
Some people are so ignorant that the first physical symptom that they experience after starting to vape, must be caused by the vaping and not the years of smoking they've already done. Not to say her pancreatitis was caused by smoking either, who knows what caused it, but it was too late-she couldn't be convinced otherwise.
