That's a really old-fashioned concern. It used to happen in the 50's and 60's, but patient rights have come a long way since then. The most anyone can do in CA is 5150 a relative, which is a 72 hour hold. That's not done more often because in 3 days and they're out on the street again, refusing to take meds. Mental health pros need to be able to hold someone longer and force a 30 day injection of psych meds. Paranoid schizophrenics usually won't take their meds because they don't trust the system naturally. They are unable to make a rational choice (obviously) So we just abandon them and ignore them.

Not in California. Impoverished people have access to basic free health care with Covered California. The mental health people I talked to at the local hospital were very well qualified. Too bad I was too screwed up to listen to them.
