Smoke comes through the ventilation system

I am smelling marijuana smoke in my apartment right now which is circulating through the common heating system. This has been a persistent issue since June 2020, and has dramatically increased since August of this year and has become unbearable in the winter months when I am unable to prop the windows open to air my apartment. It is unacceptable that non-smoking residents of Van Ness are subjected to constant second-hand smoke - this is a health hazard. There is acrid smoke in my kitchen and bathroom every evening that comes in through the ventilation system because of which I am unable to enter those areas.
