Also, people in half way houses or assisted living absolutely should be sober so they don’t cause anyone else in the facility to regress, but it is a hard problem. These people often need intense rehabilitation and these programs are neither quick or cheap. Someone has to run the program and success is never guaranteed. Mandatory government funded rehab would be AMAZING, but imagine how many people would crow about their “freedom” to shoot up meth is being infringed if that happened at the federal level.
This is a very hard problem and there aren’t easy solutions. My opinion changed a bit after I married a girl with a masters in social work. This is very draining heavy emotional capital work.
