I am 50 years old and smoked 1.5 to 2 packs a day for over 30 years. In August of 2013 i switched to ecigs completely and haven’t looked back. I feel better than i have in many years. I have tried quitting several times and the only thing that worked for me is electronic cigarettes. I started with the V2 cigalikes, switched to ego type battery and protanks. Now use mech mod with rebuildable atomizer.
