In my opinion, living a 100% healthy life kind of defeats the purpose of living at all.
I'm thrilled with my results after I started vaping. From 3 packs a day, and feeling like I was addicted for life, to six months of not smoking. And I've cut the nicotine level down to less than half of what I started at.
If I vape the rest of my life, I'm fine with that. I'm so much better off than when I was smoking, I certainly can't complain.
But I'd like to be able to stop vaping. You seem to be assuming that the only reason to quit would be health benefits, and I disagree with that. I'm obviously saving a lot of money compared to smoking 3 packs a day, but I'd save even more if I quit vaping, so there's that. The most important thing is that, at least for now, I'm still addicted to nicotine, and the "it's time to vape" habit just took over the "it's time to smoke" habit.
I'd very much like to be able to not vape and not go through withdrawal. If I leave the house and forget my PV, it would be nice if I didn't need to go back and get it. If I'm someplace where I can't openly vape for 8 hours straight, it would be nice to not have to sneak vapes in the bathroom. Essentially, I'd like to not be addicted.
So far, slowly cutting down the nic level on my juice has worked well. As long as that continues, I'll drop the nic until I get to 0mg, and then I'll see how I do if I just set the PV aside and don't vape.
The health aspects of vaping don't worry me at all, and wouldn't influence me to quit. Those were a major motivator to get off the cigs. But it would be very nice to get rid of the addiction.
