Again, I am not a specialist on methadone.
Some people on methadone will phase it out and won't need methadone any more. I guess that is the purpose and the target. But there are people who will have to stay on methadone for a long period of time. It depends on the importance of their addiction and on the personal resources they have. It's a very complex question, and I don't have a satisfying answer for you. I'm very sorry about that. We know that we have people on methadone who are less violent. They are away from substance abuse, and it is having an effect on their behaviour. So for safety inside and outside, it's helping them.
I cannot go further. If you need more information on methadone, I will....
