So after almost 9 months of living neighbor-free, we now have neighbors. Overall they seem to be OK...no loud music, no shouting, no slamming doors or anything like that. But...there is one major issue...they like to smoke pot, every single day. Personally, I don't really care what people do in the privacy of their own home as long as they are not causing any harm to me (or innocent children or something of that nature). The problem is, the weather has been really nice since they moved in so we have all the windows open every day and the smell of it consumes our house. They don't smoke outside but the smell from inside the house is so strong that it permeates the air when they open their windows or doors. At this point in time, that just annoys the hell out of me...but we're having a baby in a few weeks and we're going to have loads of visitors (including the MWs and health visitors). I really don't need them thinking we are smoking pot in our house and possibly reporting us for this (and yes, the smell is so strong that it does basically smell like someone is smoking inside our house).
I'm really torn about what to do here. I don't know these people at all but apparently MIL "kind of" knows them because they are friends of one of DHs cousins. Us confronting them would probably end bad because I'm an overly-hormonal 9 month pregnant woman and DH has a pretty bad temper. If I was back in the US, I would just call the police and report it...but I'm wondering if that is too extreme. MIL doesn't know them well enough to say anything and we don't really speak to the cousin that is their friend.
Any fairly peaceful suggestions?
