Hello jsk
i don't live in the US, but in UK. As far as I'm aware, a person can only be involuntarily committed to a mental health hospital if they meet specific criteria. Drug/alcohol use disorder is not a criteria here.
Although it is heart wrenching, it is a difficult task to make someone stop drinking or drug taking, even when we know it may shorten their life. Especially when that person is an adult.
You can find out if it is possible where you are to have him committed against his will, but that doesn't guarantee that he won't start drinking again when he gets out.
This has been a long road you have travelled with him, and I know how utterly exhausting and destructive the impact of addiction can be on everyone.
Wishing you the best
Much Love
