Rates of substance use are higher in people with mental health problems compared to the general population and particularly in people with bipolar disorder, with cannabis the street drug most frequently used. Estimates suggest that up to 64% of this group have tried cannabis at least once in their lives, against about 30% of those without the disorder, despite only being about 2% of the overall population.

Specific reasons for the high levels of cannabis use in bipolar disorder are not yet fully understood. Retrospective studies (using case histories and qualitative interviews) suggest that individuals see cannabis as sometimes useful for managing symptoms of mania and depression. However, a number of large scale research studies have found that cannabis use is associated with significantly more manic and depressive episodes.

In today’s media reports about mental illness, there is a tendency to emphasise a supposed risk between violence and mental illness.  News stories regularly suggest that there is a strong connection between mental illness and crime.  In fact, people with a mental illness are more likely to be the victims, rather than the perpetrators of violence.”

“Recent studies have showed that alcohol and substance abuse far outweigh mental illness in contributing to violence.  A 1996 Health Canada review of scientific articles found that the strongest predictor of violence and criminal behaviour is not major mental illness, but past history and criminality.”

On the question of does mental illness cause violence?  The CMHA does go on to say:

“Mental illness plays no part in the majority of violent crimes committed in our society.  The assumption that any and every mental illness carries with it an almost certain potential for violence has been proven wrong in many studies.
