I've had a lot to say on the topic in the past. To sum up my view, context is key. A program like this can be an expression of despair, fear and/or contempt, or it can be a way to engage addicts and try to keep them healthier until the enter recovery.
Recovery is the key. I'd pose the following questions:
Does treatment on demand exist? If not, does the facility consider it their responsibility to advocate for treatment on demand?
Does the program view recovery as the ultimate goal?
Does the facility believe that it's clients can achieve recovery?
Are they capable of offering hope for recovery to their clients and the community?
Does the program view drug use by addicts as a life style choice, or as a symptom of the treatable illness of addiction?
Does the program represent the best use of scarce resources available to help addicts?
San Francisco does have a policy of treatment on demand, but it has never been anywhere near adequately funded.
