Substance use disorders occur in situations of problematic substance use (alcohol and/or drugs) which lead to disruptions of daily living including health problems, disability, and failure to meet responsibilities. Substance use disorders are often diagnosed concurrent to other mental illnesses such as anxiety, and are often linked to prior stressful or traumatic events. Further information about substance use disorders is available from Canadian Centre on Substance Use and Addiction.

This page provides information about hospital admissions and emergency department visits related to acute intoxication, withdrawal, and other substance use disorders. Overdose-related hospitalizations and emergency department visits are not included in this analysis. Opioid poisoning-related emergency department visits, hospitalizations and deaths are available from our opioid HealthSTATS pages. An Opioid & Other Drug Overdose Syndromic Surveillance Report is produced weekly by the health unit to track emergency department visits related to unintentional overdose at Simcoe Muskoka hospitals. Information about occasional and routine cannabis and alcohol use are available, as well as details about the prevalence of high risk alcohol use.
