Cigarette Smoke Damage affecting health

[Cora Robertson]

The new neighbors smoke marijuana and cigarettes for hours on end every day causing a hostile living environment. My son and I are both affected by secondhand tobacco smoke. Secondhand smoke has been seeping into my and other people's units via the ventilation systems. For the past three years, I have had a positive rapport with my neighbors and never had any issues until they moved in.
The smoke triggered my asthma and made my son cough uncontrollably. Smoking is against the rules of our community. Furthermore, the behavior is causing me mental, physical, and financial stress. The cigarette smoke is so strong that it is seeping into both my son's and my hair, clothing, and valuable items. I went to work with a strong nicotine odor embedded in my clothing. (Which is prohibited in the medical field) My son and I are unable to open the heat vent because the smell of marijuana and cigarette smoke coming through the ventilation system is too strong. I attempted to resolve the problem by politely asking the down stair unit to follow the building's no-smoking policy. She denied smoking and claimed it was a candle before aggressively slamming the door in my face. Later, neighbors admitted that they were having a problem with the smoke coming into their unit as well and stated that it started when they moved in about two weeks ago. I have high-end items and furniture that may be damaged because cigarette smoke has been embedded into the fabric. I have bought products and I have to keep my window open which is raising my heat bill. I had to take my son to the pediatrician and I had to go to the doctor because my asthma was flaring up. I have reached out to my landlord which reached out to her landlord and we have not heard anything and she has not offered any assistance. Who is liable for the damages?

I've contacted the management team and my landlord, but it appears that I'm being ignored. This neighbor constantly complains about my son's every sound, even though he's gone for eight hours a day and sometimes two days a week, but will not stop smoking cigarettes/ marijuana and destroying my property. Despite her demands that my son is quiet and not make any noise. She turns on her television at full volume until 4 a.m.

Find another place to live. This woman won't improve her behavior and your Landlord won't fix the problem for you. Finding a new place to live is the best solution.
