Substance Use Service/Addictions Medicine

A collaboration with Addictions Medicine and Addictions Psychiatry

“Addiction” refers to a pattern of behaviour or substance use that is characterized by the “4Cs:

  • Craving
  • Loss of Control of amount or frequency of use
  • Compulsion to use
  • Use despite Consequences

Substance Use Disorder, the current terminology, is a chronic condition in which repeated drug or alcohol use causes changes in brain circuitry which lead to biological, psychological, social and spiritual manifestations (American Society of Addiction Medicine, 2011)

Our service takes a holistic approach to the assessment and ongoing management of all substance use disorders, including alcohol, opioids, cocaine, tobacco and cannabis.

Your Care

This program offers an integrated approach for patients who have problematic use of alcohol, opioids, benzodiazepines, cannabis or other drugs, including:

  • Assessment of substance use concerns and review of treatment options
  • Brief individual counseling and psychotherapy
  • Management of acute alcohol and opioid withdrawal
  • Outpatient tapering of patients on high dose opioids or benzodiazepines
  • Medication assisted treatment for alcohol use disorder, opioid use disorder and  cannabis use disorder
  • Group counselling:  Early Recovery group, Seeking Safety group
  • Referral to longer-term treatment programs
  • Reintegration support for patients who have completed residential treatment
  • Education on overdose prevention and use of naloxone

Our Clinics

Our Substance Use Clinic operates Monday through Thursday, between 9 a.m and 4 p.m. We accept patients by self-referral as well as referral from their physician.
An initial consultation is followed by treatment planning and follow-up, including medication, counselling, referral to community programs, and ongoing support to the patient's primary care physician. 

The Rapid Access Addiction Medicine Clinic (RAAM) is a clinic where patients who are in urgent need of an assessment can be seen without a booked appointment and without a physician referral. Clients will be assessed by our Addictions Nurse, Irene Njoroge and directed to an Addictions Physician immediately for assistance with stabilization.

Clinic Hours:
Monday, Tuesday, Thursday 10:00AM-12:00 PM
Walk-in (no appointment necessary) but please arrive before 11:30 for registration.

These guides should be given to patients that have been diagnosed with an alcohol use disorder or an opioid use disorder. They provide information about the causes of addiction, outline treatment options, and offer some suggestions for dealing with cravings in early recovery.
