I have one comment regarding that.
We don't have many in our program. I know Vancouver has quite a few and I don't know how many James does in Ottawa. We have a couple in our program and we have found success with them as well, but it is a lifelong drug that they're going to be on with methadone. It is harder to get off than any other drug. It is very similar to something like insulin for a diabetic. Once they're on it, they're on it for a lifetime.
