I always vape at work but, keep a low profile. The vast majority of people are quite cool with it, even the non smokers. I have been asked; now that you have quit smoking, when are you going to give up vaping? I usually respond with, if I'm not vaping then I'll probably be smoking again, what would you have me do? Then I explain to them that I loved smoking, I just didn't like what it was doing to me, if it wasn't for e-cigs I would certainly smoke till the day I die. Having said that, those are the oddballs out there and do not reflect the majority of people that I meet. There is a mechanic that I work with (a non smoker) who told me that he would not have a problem with someone coming to his house and vaping. He added that he has a few smoking friends that he was going to be sure to tell them about e-cigs because he thought that they were such a good idea. Another co-worker (non smoker) was so interested that he bought his mother a kit that I recommended for christmas, and she has been vaping ever since. I look at this way, most non smokers are part of the solution, they all know a smoker or two, and can help converting their friends and family to vaping. Granted, your always going to have your hard line "quit or die" zealots, but in the end they're the ones who are going to look silly. It's all about harm reduction, for everyone, including the zealots.
