Dual using to be a moderate smoker, like I am, strikes me as actual cheating. I'm a smoker who isn't addicted to smoking (because of vaping). That, I reckon is cheating among even people in this thread.
But as one who's done cold turkey before, I can relate to how ANY version of NRT would be seen as cheating and why vaping might be perceived in that vein even more. To which a person who likes nicotine would be like, 'and so? What's the problem?'
But for those who are all high and mighty on quitting is so praiseworthy, then I think NRT is cheating your way toward whatever the alleged goal is. You are taking a journey toward that goal by trying to have your cake (or nicotine) and eat it too (use while claiming to be a quitter). But stipulate it all with "at least I don't smoke anymore." To which my dual using self that's done the full liberation thing previously is like, "so, what's your point?"
