I live in Chicago in rented apartment above illigaly rented basement. My neighbors from that basement are smoking cigaretes inside and all the smoke comes to my place. I tried talking to them and they always say they will stop but they still do it. I talked to my landlord but she said I have to take care of that. Is there anything I can about it ? When I was signing lease landlord asked me if I smoke or not because she doesn't want people smoking inside. There is nothing on the lease about smoking.Please help because my place smells like an ashtray.
