How long can you keep someone in, if you hospitalise (I'd say 'section') them involuntarily?
If he'd been admitted in 2016, would he not have inevitably gotten out again before now?
Perhaps I'm being pessimistic in ruling out the idea that he'd have been 'cured'.
In Ma, we have two means of holding people, one is section 12 and the other section 35. From what I understood when I was dealing with it, Fl is the only other state that allows sectioning but I can't be sure, that was 3 years ago.
Section 12, a family member will usually take the person to a hospital for a mental health evaluation but anyone who deems you a credible threat, say through calling in a "wellness check" to the cops, could lead to a sectioning. I can tell you from experience, its quite easy to talk ones self out of the sectioning. You basically talk to one shrink and a whatever nurse is assigned to observe you for 24 hours. If they do keep you its for 3 nights and if they want to keep you ionger, they need to either solicit your consent or seek it through the court.
Section 35 can hold someone for 90 days but in reality because of a shortage of beds, its 30 days maximum. Mostly, you complete 32 classes regarding drug and alcohol abuse. Classes are set to 16/week so you're guaranteed at least 17 days or so depending on which gay you arrive and who your case worker is. That's important- they make it clear they aren't counselors, you have a case worker who's job it is to process you through. They will make some effort to see that you have a place to go AND that you're wanted there. No restraining orders etc. But, if you just tell them you have a place to go, you're good. If you tell them you're homeless, they arrange public transportation.
You're held in a jail although kept separate barracks. Some get out in 3 weeks, some are held for more but its more a test on whether you can follow a schedule and not get into fights. Fighting leads to the hole and more importantly missed classes that have to be made up when the class rotation comes back again so it could add way more than the 5 nights in the hole.
It still doesn't work for those who don't want help. And its used way more as a means to get addicts off the street.
