smoking in household

Hello ladies i have a question. My son is 9weeks old. I live with roommates and my bf and my other roommate smoke hookah. But my bf also smokes weed but outside of the house. Im wondering if the smell of hookah will cause asthma to my 9week old baby? Also i sleep in the room upstairs with my son and dont take him out of the room at all and the smoke or smell dont come in the room. Is it bad for the baby to live in the house where they smoke hookah? I have talked to my bf about it and the other guy but still nothing. What can i do? I dont want to hurt my son and cause him to get asthma.
