Grandfather to-be smokes, what effects could this have on my baby?

My kid suffer from 7 cases of bronchitis in her first year of life because of her Grandfather (my fil) smoke in front of her. Even though we move out when she is 4 months old, she is still suffering from second-hand and third-hand smoke as they continue to smoke in front of her when we meet (twice a month) which resulting her in having cough and lung infection every month after the meet-up. It is best the Grandfather quit smoking and have his house a total clean-up.
