Obviously, I'm concerned about the harmful effects on mental health.
Dr. Sabet, I think that you mentioned increased risk of mental illness: schizophrenia, psychosis, depression, and anxiety. We are having a lot of incidents today of violence in workplaces: shootings, stabbings. In Nanaimo just last week four people were injured and two died. Those were shootings. There were stabbings in Calgary yesterday. These incidents are happening across the country, and it seems to me many factors may be involved in people cycling into violence with their mental health issues and their inability to resolve conflicts. It may be complicated, but I think we ought to be concerned that drug use is contributing to these things.
From your experience, can you comment further on the contribution of marijuana leading to psychosis and other mental health issues?
