What Is Alcohol Use Disorder (AUD)?
Alcohol use disorder is a medical condition, not a moral failing. It affects an estimated 1 in 10 Canadians and exists on a spectrum from mild to severe. Understanding what it is, and what actually works to treat it, is the first step toward change.
Signs and Symptoms of AUD
The DSM-5 defines alcohol use disorder through 11 criteria. Meeting 2 to 3 criteria indicates mild AUD, 4 to 5 indicates moderate, and 6 or more indicates severe. You do not need to hit rock bottom to qualify for a diagnosis.
Here are six of the most common signs:
- 1.Drinking more, or for longer, than you originally intended.
- 2.A persistent desire to cut down, with repeated unsuccessful attempts.
- 3.Spending a significant amount of time obtaining, using, or recovering from alcohol.
- 4.Experiencing cravings or a strong urge to drink.
- 5.Failing to fulfill major obligations at work, school, or home because of drinking.
- 6.Continuing to drink despite ongoing relationship or health problems caused or worsened by alcohol.
If any of these feel familiar, it does not mean you are broken. It means your brain has adapted to alcohol in a way that is measurable, diagnosable, and treatable.
What Causes Alcohol Use Disorder?
AUD is not caused by a lack of willpower. It is driven by changes in brain chemistry, specifically the dopamine reward loop. Over time, repeated alcohol use rewires the brain's reward system so that it begins to prioritize drinking over other sources of pleasure or relief.
Genetic predisposition plays a significant role. Research shows that genetics account for roughly 50% of the risk for developing AUD. If alcohol problems run in your family, your brain may be more susceptible to these neurological changes.
Stress and trauma are also major contributors. Many people begin using alcohol as a coping mechanism for anxiety, grief, workplace pressure, or unresolved trauma. What starts as self-medication gradually becomes a pattern that is difficult to break without the right support.
Understanding the cause matters because it shapes the solution. AUD responds to medical treatment precisely because it is a medical condition.
How Is AUD Diagnosed?
A diagnosis is made through a physician or nurse practitioner assessment using the DSM-5 criteria. The conversation typically takes about 30 minutes and covers your drinking patterns, health history, and how alcohol is affecting your daily life.
At Heal@Home, no referral is needed. You can book a private medical intake directly and receive an assessment from the comfort of your own home.

Evidence-Based Treatment Options in Canada
Effective treatment for AUD is not limited to 28-day rehab programs. In fact, some of the most successful approaches happen entirely on an outpatient basis.
Therapy: Cognitive Behavioural Therapy (CBT) helps you identify the triggers and thought patterns that drive your drinking, and build healthier responses. Weekly sessions by video are just as effective as in-person therapy for alcohol use disorder.
Medication: Naltrexone is a non-addictive, FDA- and Health Canada-approved medication that reduces cravings by blocking the endorphin rush that alcohol produces. When used as part of The Sinclair Method (TSM), Naltrexone is taken one hour before drinking. Over time, the brain gradually unlearns the association between alcohol and reward. TSM has the highest published success rate of any single approach to reducing alcohol consumption.
Combined approaches: At Heal@Home, we pair medication with matched therapy because the evidence shows that the combination is more effective than either one alone. Learn more about our treatment programs.
Why Most Canadians With AUD Never Get Treatment
Fewer than 10% of Canadians with alcohol use disorder ever receive treatment. The reasons are systemic, not personal.
- Stigma: The belief that seeking help means admitting to a character flaw keeps millions of people silent.
- Privacy fears: Many worry that treatment will appear on health records, affect their job, or become known to colleagues and family.
- Waitlists: Publicly funded addiction services in Ontario can have wait times of 3 to 12 months.
- Cost: Private rehab programs often cost $10,000 to $50,000, putting them out of reach for most families.
- Lack of awareness: Most people have never heard of Naltrexone or The Sinclair Method, because the traditional treatment industry rarely promotes them.
Heal@Home was built to remove every one of these barriers: private, affordable, virtual, no referral, no waitlist.

Frequently Asked Questions About AUD
Is alcohol use disorder the same as alcoholism?
AUD is the modern clinical term. Alcoholism is an informal, older label. AUD is a medical diagnosis based on 11 specific criteria and covers a spectrum from mild to severe. It does not require physical dependence.
Can AUD be treated without going to rehab?
Yes. Evidence-based outpatient treatment, including medication like Naltrexone and weekly therapy, is clinically proven to be as effective as residential rehab for most people, with significantly less disruption to daily life.
How long does treatment take?
The Sinclair Method typically shows measurable results within 3 to 6 months. Many clients continue for 12 months or longer depending on their goals, whether that is moderation or full abstinence.
Is Naltrexone addictive?
No. Naltrexone is non-addictive. It does not create a high or a buzz, has no withdrawal effects, and is in a completely different pharmacological class from addictive substances. It is a tool, not a treatment you become dependent on.
Does private treatment show up on my health record?
At Heal@Home, treatment is private-pay and operates outside the provincial billing system. It does not appear in shared provincial health databases and is not reported to your family doctor or employer.
