Little late to the party here. Started Vaping Sept 2016. Can't remember the day though.
Still eternally grateful to my fellow coworkers who talked me in to doing it. Only a week of dual use and i haven't had a smoke since.
I can't talk anyone else into it though. My best friend still spends around $120 a week on smokes. Over 6 grand a year and he won't even try a vape.
