Involuntary Rehab for addicts?

I don't think so, my Aunt was forced into rehab every time she went to prison and that never stopped her from using once she was out,

People need to save themselves for it to really stick

How to do this is still a mystery

Educating and letting people know what is available is all I can think of.

If they break the law, mandatory work programs are also all I can think of...

It doesnt work.. Sure you can force them to dry out. But you cant make them not want to start using again.. You have to wait for them to want that..😷

For it to be efficient, rehab needs to be voluntary.

No one will quit unless they want to

No. Rehabs where people go wanting to have a less than 50% success rate at all.
