Thank you, Mr. Chair.
The only one that comes to mind right now.... We've talked about this a lot, we've had a lot of drug issues, and I found this in my previous career. There's a huge interplay between mental health, drug addiction and substance abuse in general. We know that a very large proportion of drug use is by those with underlying and as yet undiagnosed mental health issues who are attempting to self-medicate, even teenagers.
We've diagnosed schizophrenia in teenagers brought on because of their drug use, and it turns out they were taking drugs because they were hearing voices. In this population it's very hard to track meth in particular, and as you said, Dr. Young, these people are often under-represented in surveys.
Do we have any idea of the proportion of those who are addicted to methamphetamine right now that have underlying mental health issues, whether it's a severe mental health diagnosis like schizophrenia, bipolar illness or anything like that?
