How is vaping better than nicotine patch, assuming that the poison is not considered a feature?
We haven't done much research on vaping as a smoking cessation tool. We've done a bit on other forms of nicotine replacement, and they are more effective when they're delivered as a package of treatment, and less effective if they're used alone with nothing else. Some smokers who've switched to vaping are now in a weird super-position state: they don't smoke right now because they vape, but take the vaping away from…
That's not likely, unless their vapes were just ripped away without warning (even less likely). People that want(ed) to quit, including myself, gradually taper their nicotine to zero, and then one day just put down the vape and don't go back to nicotine in any form.
