Like others have said, I have had positive reactions from positive people. My carer is a lifelong non smoker and always wanted me to quit because it was what I wanted, and because of the smell, mess etc. She loves the vaping because it's not smelly and doesn't leave cig butts everywhere and all of that, plus it's better for me. She even likes the smell of some of the juices. On the other side, the only smokers I know either haven't seen me vape, or are now ex smokers and on the vape themselves...so I've had a pretty positive reaction. I haven't vaped that much in public, but will be sure to be the same as I was when I smoked, aware of people surrounding me and all of that.
The majority of us are ex smokers and one thing I didn't like as a smoking trying to quit or not, was the people who were so holier than thou because they'd broken the addiction and managed it. They seemed to forget how hard it was. I'm happy vaping and it's doing less damage than smoking cigs so I'm happy no matter what anyone else thinks.
