No, not specifically on 12-step programs, but there are models with regard to mental health services.
When people are under an Ontario Review Board order and they are transitioning into the community, the community providers actually will go into the forensic hospitals and work collaboratively with the hospital staff there so that there is greater continuity when the person transitions into the community.
Presumably, there could be parallels. That's with mental health. I could see parallels certainly being applied to an addictions context.
