I’ve been smoking since i was 14 years old now 55 . I smoked 2 to 3 packs a day, in august 2011 I went on vacation a girl friend & her son . Her son was complaining about OUR smoking , so bought an e-cig mod at a circle K since then i weeded myself off of cigarettes with vaping, my lungs have cleared up with that. I,m not coughing my brains out . I.m breathing a 100% better In short & long vaping has saved my life !!!!!!!! I have been smoke free for three and half years, i vape with a .03 nicotine. Yes i have used the patch ; gum ;counseling ,nothing worked but vaping is !!!!!!!!!!!!!!
