2.) I have diminished lung capacity due to an illness a couple years ago, so I really really have a hard time with him smoking. I don’t let him smoke in the house but do let him smoke outside, but I still smell it on him and his clothes. I have to have an air purifier going in the house 24/7 due to the smoke that clings to him and his clothes. I really don’t have a problem with my lungs/breathing unless I am around smoke (or exercising excessively).
