It's been hot out lately so I've been keeping the windows open (no one really has AC in the Seattle area since it never gets that hot). Our neighbors (who are renters) are constantly smoking in all day. My house smells like it whenever the window are open and I don't want my LO's to breathe it in. There are about 15 people living in the house and 10 of them are children under the age of 8. I don't know whether to call the police or let them be?

What would you do?
