I smoked 2 packs a day of unfiltered Pall Malls for over 40 years. I tried to quit numerous times using the patches, pills, etc. without success. I tried an electronic cigarette just to see what they were all about. That very day I quit cigarettes and have been smoke free for 2 years and 11 month as of 7/29/2013. I have talked with my heart and lung doctors several times about using e-cigarettes and both say they are better than cigarettes and if an e-cigarette keeps me from smoking then just go for it. My experience with the stop smoking pills, patches, and etc. led to a 100% failure rate for these high priced alternatives to smoking. My success rate with an e-cigarette is a 100% success rate. My quality of life has also improved since I no longer smoke tobacco cigarettes.
