After reading some research about vaping affecting people's lung capacitys I thought I would conduct my own research into it so who has noticed increased lung capacity from quitting smoking to vaping do you have any evidence to back this up ie has a doctor told you or do you just generally feel better and on the other side does anyone feel like it has made no differance or even a negative differance not limited to just lung function ? Will post link to the research as soon as I'm on my pc thanks
