I have become an accoster of strangers smoking in public places ... more times than not, when I see someone smoking outside of a store or restaurant, I'll go up to them (non-aggressively) vaping on my pv, and hand some literature to them on vaping. Not once have I been rebuffed for it. I just believe that if I hadn't heard about vaping from another person (non-smoking husband), I NEVER would've known. Well ... maybe after I had smoked for "x" number more years.......
