Hi there. I need help. I am extremely sensitive to smoke and can smell it a mile away and smoke irritates me. We own a duplex which shares a wall with our neighbors. It only started this year with smoking all the time inside the house. The mother, daughter and son all smoke in there. If the kids have friends over, even more smoking happens. It's so bad that when my husband goes there for a meter reading he comes back smelling like smoke and I go into a coughing fit. I think I am developing a chronic cough from having to inhale the smoke all day long. We have bought an air purifier and changed the filters on our house. Nothing seems to be working and I just break down and cry sometimes from all this coughing. Nothing we can do legally since they own their side and we have already subtly suggested that their smoking is causing me issues and they still continue. Is there anything anyone can suggest that might be able to help? Maybe there's something out there I don't know about. Also, moving is not an option sadly.
