I have smoked for over 30 years and my wife is from Germany, she tells me that her parents let her smoke at home from the time she was 3 years old, by age ten she was over a pack a day, at 50 she had bad lung problems and still could not quit, after I got her a E-cig she has not touched a ciggerett since! thank god for that, while I'm still not sure just how good or bad E-cigs are for you, but they are definitely better than tobacco. we have both used them for about over a year now. and we love them.
