Those were very stimulating comments. I think Intervention, the TV show, makes great television. It's not best practice, in terms of how to deal with families.
A fair bit of my work has been with families affected by concurrent disorders. We have to be careful here to not characterize family members as enablers in the way you described.
I don't know the percentage on this, but many families are concerned that ultimately they're going to be part of the solution people will need when they return to the community. Having social support and family engagement while people are incarcerated are positive things. The issue of detecting individuals who are collusive with an inmate who wants substances brought in or who think they're actually helping the inmate by doing that has a number of challenges against it, for sure.
Educating folks is an important thing in this regard, but I would frame it quite differently. We need to have more family engagement and support, including support for family members on a peer basis. You could create a culture where you would be promoting the message that the best solution for people with addiction issues in prison is to deal with the addiction, rather than feeding it while doing time.
