what to do when neighbors smoke marijuana (apartment)

Ta

So we are currently living in an apartment. We havent got new neighbors or anything but recently (probably for the past week), the smell of marijuana is here. It upsets me so much because I'm pregnant and the smell of weed is a trigger for me of a past bad situation. I HATE it. I just want to cry :( Its not legal in our state and idk what to do. Idk which neighbor is smoking as we have neighbors attached on the left, right, and behind us. I want to let management know but idk if they will be able to do anything unless they actually know which unit it's coming from. What do you guys think?
