It's been... interesting so far. Back when e-cigs came on the market, I looked at them in disdain. when my friend decided to go with them, I don't even want to echo the things I called him. Now here I am with one and I am proud as hell for it. My bartenders give me crud for it but they do it out of fun (and honestly appreciation). When it started raining, I took shelter under the entrance of an office building and the receptionist came outside to tell me that he would appreciate that I smoked elsewhere. I calmly was about to explain to him what I was actually doing before he said "oh that is an electric kind? nevermind!"
My only problems so far? Smokers. "What the hell are you smoking?" "Ehh, it's just not the same!" BLAHBLAHBLAH. Now I'm very young. And the ridicule I get from some people (my age mind you) is at times disgusting. But my mindset is hellbent on getting off cigs (and at twelve bucks a pack?) and I vape with pride. I found vaping a lot like fashion. There are people who follow the same crowd that has existed for eons and these people are the people that I have learned to not deal with. Say what you want, I'm saving money, I get to stay inside and socialize, my health is getting better, AND I can actually taste what I'm drinking now.
Screw the public, with time, everything will change for the better... as long as you participate in it.
