Thank you for your reply. These people stand right outside the apartment building , smoke weed and use threats to intimidate residents coming and going to their apartments. I originally thought this was a knee-jerk reaction for the people but now I believe it's done to keep people from reporting their illegal behavior. To do this right outside someone's residence is the ultimate disrespect and a major safety issue for everyone.

ALL solutions that could be thought of have been considered in-depth, including a number of novel legal methods. These people are extremely aggressive, inconsiderate, persistent and frustrating causing but my best guess is they will not be allowed to live here much longer. It may take law enforcement physically wrangling them out. It's really that bad.

Also, I will add, just for societal sake, drug education, including casual "education", teaches that "drugs are bad", for health. Obviously they are but what the education does not tell is the truth that in addition to bad health illegal drugs cause MAJOR NUISANCE. I'm living it and have seen it, particularly with "weed". It's a myth that it makes everyone peaceful, happy, loving etc.. It makes some people highly aggressive, inconsiderate, loud, reckless and threatening, just like my neighbors. In The Netherlands, cannabis is not legal, it's "tolerated" and what many people do not know is that if there is any nuisance associated with cannabis there can be substantial legal issues for those causing it or facilitating it. That country got it right decades ago but even they still have major issues with all drugs.
