As a longtime tobacco user, I made the switch to vaping about 4 years ago. I agree with the above posters that speak of either cheap knock off batteries, and overly ambitious "Mods". I don't even like going into a vape store anymore and purchase anything I need online because of all the idiots toking on their drip mods with coils that they wound themselves, and that resemble the huge exhaust tips on some kids Ricer-mobile. They seem to think they everywhere they go is a cloud competition. I was grateful that vaping allowed me the opportunity to give up tobacco when nothing else worked, and as far as whether it's as harmful or not, time will tell. but common sense would dictate that inhaling something that is essentially on fire or at least smoldering is bound to be more harmful than water vapor with a little nicotine added. My bottom line is that its all about moderation, and whatever you do, you need to make sure you know what you're doing. I would bet money that every one of those 66 incidents involved either cheap knock-off hardware/batteries, or some idiot who was pushing the envelope and lost.
