In Canada, one in three people will experience mental illness in their lifetime.
Concurrent disorders are defined as co-occurring substance use disorders with other mental health conditions. For example, up to 40% of people who are diagnosed with Major Depressive Disorder will also have a co-occurring substance use disorder. Despite the prevalence of concurrent disorders, people who live with them tend to be under-diagnosed and under-treated. When care is provided, conditions are often treated separately rather than in an integrated way.
