Being truthful, I really don't know. I would definitely go to another nic source first, like the gum, snus, or if I still had my nic base, utilizing it in an oral absorption method. If all my nic and gear were suddenly gone and irreplaceable, that is really the only scenario I can imagine being unable to vape, so that would be because of some major tragedy or unforeseen life circumstances. If it were for health reasons, I'd like to think I would have he strength to abstain from smoking , but my past history had me smoking days after release from the hospital for cancer surgery.
It would really depend on the mental state I would be in, at such a crossroad. I smoked from age twelve till age fifty two, so more of my life was spent as a smoker than a non smoker, and I have been smoke free and vaping for four years, the longest smoke free period of my life since starting, so there is that...
Also to note, I liked smoking, and had accepted the fact that after a year and a half quit attempt I suddenly caved in a moment of weakness and got right back on that train, and at that point had resigned myself to just being a smoker till I died.
If I was told tomorrow that I had two weeks to live...I'd probably fire one up just because.
