If you look at the polls, it's somewhere above 82% of people responding that have completely stopped using combustible cigs (including me, 14 weeks without smoking a cigs). Three's also a percentage of people that vape 0 mg, or very low nicotine (not me though). The people who've completely stopped vaping tend not to stay around on the forum, but I've seen a few farewell posts.
I'm glad to avoid the tar, arsenic, etc., etc. in combustible cigs.That's enough for me right now. I can see myself, maybe, slowly cutting down the nicotine and weaning myself off- but very, very slowly if at all. I'm not convinced that nicotine alone is such a horrible thing.
BTW, there's a move to shift the guidelines for NRTs to use for up to 6 months after smoking cessation. Wonder if that will help that route to have better success than it currently does
