The smoke residue on clothes will probably not penetrate into the lungs like actual second hand smoke can. But, as you have experienced, the smoke odor from the residue on clothes can also hit you like a ton of bricks and will irritate the nasal passages and eyes. This irritation can make a person more susceptible to infections. It will be important for your husband to use a “smoking jacket” that he can take off after smoking.
“Is smoke odor on your hands and clothes considered second hand smoke? My daughter continues to get sick and I am beginning to wonder if it is the smell from my husband’s clothes and hands that could be the culprit. He does not smoke inside but when he comes in from smoking the smell can just about knock you out.”
