Substance Use Disorder Treatment: Medication Costs in Canada
Medications for opioid, alcohol, and tobacco use disorders are effective and increasingly covered. Here is what they cost and how to access them in Canada.
Medication-Assisted Treatment: Breaking Down Costs
Substance use disorders affect over 6 million Canadians in some form, and medication-assisted treatment (MAT) is one of the most effective approaches. Yet many people do not access treatment because they are unsure about costs or coverage. The reality is that most substance use medications are affordable and increasingly covered by provincial health plans.

Cannabis Use Disorder
There are currently no approved medications specifically for cannabis use disorder. Off-label treatments being studied include:
- N-acetylcysteine (NAC): $15–$25/month OTC — some evidence in adolescents
- Gabapentin: $10–$25/month — early evidence for withdrawal symptoms
Accessing Treatment
Step 1: Talk to Your Doctor
Any physician can prescribe naltrexone, acamprosate, or smoking cessation medications. For opioid agonist therapy, physicians need an exemption under the Controlled Drugs and Substances Act (or equivalent provincial authorization), though this requirement has been simplified in recent years.
Step 2: Confirm Provincial Coverage
Call your provincial drug plan or check their formulary online. All OAT medications are covered. For alcohol and tobacco medications, coverage varies.
Step 3: Compare Pharmacy Prices
Use TransparentMedz to compare costs, especially for medications with co-pays. The difference between pharmacies can be $10–$30/month for medications like Suboxone.
Step 4: Check Specialized Programs
- Canadian Mental Health Association: Connects individuals to local treatment resources
- Connex Ontario / provincial equivalents: Free helplines for substance use treatment referrals
- Health Canada Special Access Program: For medications not yet approved in Canada
The Bottom Line
Medication-assisted treatment for substance use disorders is effective, affordable, and increasingly covered across Canada. Opioid agonist therapy is free in every province, alcohol medications cost $25–$70/month generic, and smoking cessation programs offer free medications in many provinces. Use TransparentMedz to find the lowest pharmacy prices and remove cost as a barrier to recovery.
