Thanks again to all. Sure, later I'd like to post some reviews (maybe?) or at least how my vaping experience goes. And yes, if possible I want to have my lungs back like they were before I started smoking. My doctor once said that 5 years after a smoker stops smoking, his lung can get back to pink like those of a teenage non-smoker (not brown or black like other smokers). I don't know if he was just trying to persuade me to quit smoking (which I did not not then) or if it's true. Does anyone know about it?
