Thank you, Mr. Chair.
Thank you, everyone, for coming.
I'm a physician. I've practised emergency medicine for 17 years, so of course, we would often see the different aspects of mood disorders either previously diagnosed presenting or sometimes we would see a first diagnosis. Mr. Upshall and then Mr. Gallson, in reference to mood disorders, one of the things we have always known about is the link—in young people, particularly, but in all groups—between substance abuse and mental illness. The link is clear; the causality isn't as clear as a chicken-and-egg thing. We do know, and I've diagnosed this on more than one occasion, that when a young person is brought in with a drug problem, it turns out their symptoms of mental illness actually predated the drug use.
