While I have helped convert a good many people from smoking to vaping, the most personally satisfying conversion was to get my 70 yr old mother, a smoker for over 50 yrs, to get off the stinkies....I was a hard smoking 33 year 2-plus pack a dayer and when she saw me switch overnite to vaping and never puff another analog that's all it took to convince her that there is something to this vaping thing. She asked me questions, was able to get what she needed, and hasn't smoked since...
