vapour cigarettes

Alot of smokers i know have been using these instead of smoking, i had stopped untill earlier this year my dad had a heart attack & we heard nothing for about 5 hours so i bought some cigs (silly i know) i decided to try a vapour cig & cannot believe how well they work i have not had a normal cigarette for 1 week since trying this. I know i haven't actually stopped as in still inhailing nocotine but the shop keeper said you gradually reduce the strength of the oil that goes in them untill you reach zero nicotine, the best thing is the vapour smells of whatever flavour you use, just now in using blueberry then ill be trying banoffee pie
