Thank you, Madam Chair. In the last Assembly, the social development committee spent quite a bit of time on the issue of aftercare for people returning from treatment in the south. One of the things that we grappled with, and I don't see here but is an important part, is how to measure success. There are people, as you know, go and start treatment and don't complete it. There are people who go and complete treatment and stay sober for the rest of their lives, and there is everything in between. Do you have some thoughts about how to evaluate the results of improving the services for aftercare for people who have addictions treatment? Thank you.
