I would just address that, and since we are the Centre for Addiction and Mental Health, say that they are intertwined. We serve many people with concurrent disorders. They're not always seen together. The key is to have the most appropriate services for people, so you have to have accurate assessments of whether the person has only a mental illness, only an addiction problem, or both together. Where both together are assessed, they do need to be treated together. We don't have a good record of that in our system generally, so I wouldn't expect that it would be significantly different in correctional facilities.
We do find in our forensic programs that we have a higher representation of people with concurrent disorders than in the normal population of people who use mental health services. Substance use problems, I understand from your previous testimony, are about 80% in correctional facilities, so it's very likely you're going to find a pretty high percentage of concurrent disorders.
