Sympathies to you. I once had swift success in evicting near-by dope heads when I bought to the attention of the leasing realtor that the residents were regularly drugged off their nut, that should police raid the premises they would without doubt find drugs, and on doing so the owner of the property not just the resident would be considered as much at fault and at real risk of police action. Even stand-off owner’s don’t want that and the offenders were gone the same day. That was all based on news reports at the time in Qld where a land owner was actually charged because renters of his property were found to be growing dope there even though this was unknown to the owner. Don’t be afraid to push things to get your way and you can often act anonymously should this better suit you. All the best, C.
