I smoked since 1992 and I finally quit Jan 2010 using e-cigarettes. Nothing worked. I tried going cold turkey and I have an allergic reaction to the patches. My Drs now say my lungs sound great. When I use to smoke I had a chronic cough and always congested. They are clear an so far no signs that I smoked. I can smell and taste food again. I started off with extra high liquid nicotine and now I’m at low to medium. I started with cigarette flavor and weaned my way off that which I no longer crave the taste. I do not smoke any cigarettes at all. The smell repulses me. That would have not been possible with any other method for me. E cigarettes have been nothing but positive for me in my life. Very thankful they exist.
