The thing is you own your home and can't move. If you call the police and the police don't catch them red handed they will figure one of the neighbors called and maybe blame you. If they do, you can bet people like this can and will make your life miserable. I would call the narcotics division anonymously and maybe they can start an investigation on the drug dealing. That way the cops won't blindly come out and then not be able to do anything.
