You should totally report them.

Report them if it isn't legal where they live (but be aware that they very well may take any resulting anger out on you- bipolar people aren't rations when they get very manic or very depressed, especially someone that is self medicating) and in the meal time try to find a cheap room heater that recirculates the air in a closed room.

Talking from living with two bipolar people full time for 20 years, one of whom was unmedicated, five unmedicated bipolar people that refused to medicate that barges in and out of the house with every cycle for fifteen years, and ten years of dealing with a bipolar renter-slash-neighbor who self medicated with marijuana. Pretty fucking well versed with bipolar people at this point, enough to know it's a valid concern after the unmedicated bipolar person I lived with beat the hell out of me on three separate occasions because he was manic.

Talk to the landlord. If he's no help, move - this can't turn out well.

Because everyone can break their lease, thus giving up their deposit, and move without a care in the world

Some people own houses too. Not as easy to just up and move.

but it isn't a house.

First off- putting someone in a position where they have no choice but to be exposed to a drug in a way that means it can get into their system, is not okay. Again, non-consensual drug exposure is NOT okay.
Second off- considering that OP could show as positive on a drug test from repeated exposure and LOSE THEIR JOB, they aren't being "a pussy." They are being responsible, as well as rationally upset that their neighbor is making them choose between courting hypothermia and drug exposure. In other words, they are using their brain, the organ that seems to be non-functional for you.

Maybe don't assume that he's assuming, he could know it for a fact. Why are there so many Internet justice seekers just looking for something to complain about?

Lefties.

Years ago I had an upstairs neighbor who chain smoked when home from work and weekends were a nightmare. I ended up taking downey fabric softener sheets and using a glue gun to glue the sheets over my vents that expelled air. Whenever I ran the heat or air after the modification, it smelled like fabric softener. Maybe give that shot.

Must not be por they're smoking if they're being bipolar and antisocial.

Call the police.

I think that's something to bring up to your landlord

Also, free losing their job for smelling like drugs and testing postive for something that isn't their fault. But, free drugs are completely worth losing your job and probably home, right? Some people also have respiratory problems that could make that very dangerous.
