Your premise here seems to be that these programs are somehow meant to "solve" addiction, when in reality they're mostly critically underfunded, understaffed, attempts to paper over multiple sucking chest wounds.

The opioid crisis created a LOT of addicts, the rise of fentanyl is killing a lot of people, and combined with the mental health problems you tend to find in and around addict populations, this is a genuinely huge problem. Without a suitable mental health infrastructure, all you have left are the prisons, streets, and programs like this.

I agree that this is an inefficient way to address the problem and that a major re-evaluation is required, but probably in quite the opposite way you mean it.
