I too am not thinking of replacing vaping anytime soon. Vaping (for me) is a harm reduction device, and while I can see the rationale of lowering nic percentages over time, even getting to zero, I doubt I will do so for several reasons: 1) I've seen people returning after "quitting" vaping and then returning to smoking, and I have No Doubt that would happen to me. For me, the idea of SIMPLY switching to vaping was so overwhelming in the beginning that I am simply *thrilled* to only be vaping, reducing my risks a great deal, and whatnot. I told myself that if I were ever able to "make the switch" as it were, I wouldn't pressure myself to stop vaping, ever. B) While heart disease runs in my family and it's my understanding that nicotine use can *slightly* elevate risk of heart disease etc., my heart health generally is surprisingly good and that's the least of my worries. If I drop dead of a heart attack at some point, fine with me. Also, Alzheimer's and ADHD run in my family, and nicotine has been shown, in some studies I believe, to lessen the risk of Alzheimer's, and having seen my granny go that way-- no thanks. Also, even if I could wean myself off nicotine, which I imagine I could, I wouldn't have the "organizing" factor of nicotine to help me out with that, and it's actually pretty powerful as I have tried quitting or reducing in the past.
With that said, if anyone wants to use an e-cig to transition to 0 nic and then quit, who am I to say that's a bad idea? I'd just avoid blanket statements, though, e-cigs are not always used as transitional devices for quitting, many people are now using them as a harm reduction products for the long term. I have to say, I've found my three (almost) months of vaping to be way more enjoyable than the 6 months I spent chewing nicotine gum, and it was less expensive, too, AND I went back to smoking once I tapered off them, as well. I'm just happy to have found a harm reduction device I can use-- and enjoy-- far more than smoking that will afford me *many but not all* of the harm reduction of not smoking, while still enjoying vaping. So, just as I don't say YOU must use vaping to eventually quit, it's not helpful to make blanket statements about what e-cigs "should" be used for. If I were told vaping would only be of use to me for a few months as I "tapered" my nicotine, I wouldn't have found them appealing *at all*.
Just my 02. cents.
