You're raising a very important point. It's very key to ensure that the mechanisms of support are in place for people who have drug addiction issues and who are leaving prison. Whether that's methadone replacement therapy, or whether it's Narcotics Anonymous, whatever supports they need should be put in place.
As I mentioned, Guthrie House which is in place in British Columbia is working extremely well in terms of reintegrating into the community people who have a drug addiction. That's a peer-supported model, a therapeutic community that was created actually on the grounds of the prison, before people are released back into the community.
There are ways to do it, and it's important that it be done.
