I am in my mid 50's and had smoked since I was seventeen. My son recently converted me to vaping by buying me a Kangertech Topbox mini. I am really liking it over smoking tobacco and already have noticed some positive changes the first was that my fingers were no longer yellow! I also breathe alot better already even though it has only been a few weeks. I also no longer smell like cigs but at the current moment smell like banana candy!
