Never smoked, never will, however I am awe of the guy who came up with these things.
My observations so far has been that people aren't kicking the habit really, they are subbing real cigs for these less toxic, electric ones, which is great for their health, but no less addictive. Soooo the guy who invented these has invented a non-deadly way to get people hooked on something which they have to buy repeatedly. Brilliant!
(I say non toxic, we don't know that yet, but I'm sure they aren't as bad as real cancer sticks)
I know people who havnt smoked, but then too up e-cigs because they seem cooler now. So no doubt they are now addicted to them. *facepalm*
