Upgradeitis!
And some end up vaping more than they used to smoke, like myself, but I have found when I can't vape it isn't a big deal not like if I was in the same situation when I smoked. If I was in a situation where I couldn't smoke I would only be able to think about that next cig and when I can get out for one.
Research on it has been limited, but people that have switched have experienced health benefits (over/in lieu of smoking) and some of those people have confirmed those benefits by their doctors. I would recommend you do the same if possible.
