Thanks for all the replies! I told her that if it continued I would have to call the landlord and/or cops and she told me that I was being very insensitive and rude. Whatever! I know they're still smoking but i haven't smelled it for the past couple of days, however I have the feeling as it warms up outside it'll get worse. Its been cool and rainy here so i think the moisture in the air helps keep the smell at bay, as they say vaporizors do. So anyway I'm sure ill end up having to call eventually. Like I said I don't care that they do it, that's their business. But I do care that it sinks down into my apartment and reeks. It's good to know you all feel the same way, I appreciate your responses! Thank you!
