I smoked for about 4 years then quit when I became pregnant, haven't smoked in over 3 years. The problem is, I switched out one habit with another, eating. I want to lose weight but even when I'm slightly agitated I eat. I noticed I eat now when I would've smoked back then. My question is, will non nicotine vaping affect my lungs. Has this helped any ex smokers who have started eating uncontrollably lose weight?
