In September of 2012 my brother told me of how they were trying to quit smoking using E-cigs.After seeing that him and his wife were 6 months free of smoking using E-Cigs my wife and i gave them a try.From May 5 2012 to date May 24 2013 we have both been smoke free. We had tried other alternatives in the past I.E nicotine gums,patch etc and none have the same power as the E-cig to help smokers quit. The E-cig can be used all day without provocation. I use mine actually more than the amount i smoked.I can vape it all day and never feel congested or even nausious as smoking does.E-cig are somewhere around 95% air using a vegetable glycerin oil base to give it a greater smoke in the air. Its been a full year and since i started on the E-cig i have not had 1 single cigarette and am saving alot of money from it.
