My dad has been smoking tobacco for quite a long time. Probably going on 30 years by now. But he quit smoking 6 months ago and starting chewing tobacco instead... So anyway, my question is will his lungs repair themselves while he's chewing tobacco?

From smoking to chewing

I would think so. He's still getting nicotine in his system which keeps his addiction and it's certainly not good for the lips and gums, but I would think the lungs would recover with the lack of smoke.
