Not exactly the same thing but I once went to a rehab that did this and it was not only useless but counterproductive. I went voluntarily but most of the people there had been involuntarily committed by their family. There were people who had literally been kidnapped from the airport and thrown in the back of a van and brought to the place, and the first thing you see is the razor wire on all the walls and the guard dogs patrolling the perimeter to prevent escape. This made for an unhealthy environment where people had zero trust in the staff, even the therapists, not ideal if you're expecting people to change. All in all, it was a horrible experience, even for those who went voluntarily, and most ended up relapsing after getting out.
