To throw on the anecdote pile... my brother was committed due to overreaction of an LSD trip. He had been up for days and was almost incoherent after being brought in to the emergency room by the police. They said it would be 2 days, then 5 days, then another week. I called and told them that his insurance had contacted me and said they weren't going to be paying for any additional time. He was released the same day.
