doing this openly in the compound clubhouse. The drinking alone, let alone the smoking and injecting drugs.

You said you were "made aware" of and "supposedly" ....sounds like you were not the actual witness to such events. I would suggest keeping an eye on things for now, and finding the person who actually saw it happen (and can verify that they were drinking REAL beer and not the non-alcoholic stuff, that they weren't just smoking cigarettes, for example, or goofing around with someone's insulin needles, making it appear like they were injecting drugs).

People here are quick to jump to conclusions with little evidence (and most of that is circumstantial). I would caution you to gather FACTS before creating a huge incident.

I completely understand your desire not to have your family near elements like this, but I am doubtful of the story.
