I think the disposables are better than nothing or a real cigarette once you quit. I'd probably go for Nicorette gum over a smoke, but I've quit for almost a year and a half now. Really no desire whatsoever.
While not true for everyone, it probably wouldn't be the end of the world after quitting to have a cigarette or two to hold you over. If you are like me you'll prefer
vaping to smoking, so it'd be easy to pick back up with it later. During past quits, I enjoyed the cheat cigarettes and after a few days, I was back to where I was before I quit. I just can't imagine that happening if
vaping is available. It is truly a miracle.
I hope it works as well for you. Check the social forums and see if there is a vaping group near you. Seems like other vapers might be better in a pinch. Most vendors are less than 24 hours away with overnight shipping.
