Clinically reviewed by the Sober Living Clinical Team (Medical Director & Clinical Director)
Medical detox is the supervised first stage of addiction treatment: a medical team helps your body clear alcohol or drugs while managing withdrawal symptoms safely. At Sober Living Recovery & Wellness Centre in Etobicoke, detox happens under 24/7 medical supervision and leads straight into residential therapy, so there is no gap between getting through withdrawal and starting recovery. We admit people from Toronto, the GTA and communities across Ontario, and our admissions team answers the phone 24 hours a day.
Key facts
- Medical detox manages withdrawal from alcohol, opioids (including fentanyl), benzodiazepines, stimulants and other substances under round-the-clock medical supervision.
- Withdrawal from alcohol and benzodiazepines can be life-threatening. Never stop suddenly on your own; speak to a doctor first.
- Alcohol detox usually takes about 5 to 7 days, benzodiazepine tapers can take weeks to months, and opioid timelines vary widely.
- Withdrawal is tracked with validated tools such as the CIWA-Ar scale for alcohol and the COWS scale for opioids, alongside regular vital signs.
- Detox alone is not treatment. At Sober Living it flows directly into a 30-, 45-, 60- or 90-day residential program.
- Some people are safer in hospital-based withdrawal management. We will tell you honestly during the pre-admission call.
What is medical detox?
Medical detox (also called medically supervised withdrawal management) is a short, structured period in which physicians and clinical staff monitor you as a substance leaves your body, treat withdrawal symptoms with appropriate medication, and keep you physically and emotionally safe. Its goal is medical stability, not a cure.
When someone has been drinking heavily or using drugs regularly, the brain and body adapt to the substance. Stopping suddenly throws that balance off, which produces withdrawal. Depending on the substance, withdrawal can range from uncomfortable (sweating, nausea, anxiety, poor sleep) to dangerous (seizures, severe confusion, heart rhythm problems). A medical setting means those risks are anticipated and managed rather than faced alone at home. Our medical team is led by a Medical Director who is a physician in addiction medicine, and the protocol is individualized to your history, your health and the substances involved, whether that is alcohol addiction, fentanyl and other opioids, benzodiazepine dependence or crystal meth and other stimulants.
Why does withdrawal need medical supervision?
Because some withdrawal syndromes can become medical emergencies quickly, and the person going through them is rarely in a position to judge that risk. Supervision lets complications be caught early and treated.
- Alcohol: heavy, long-term drinking can lead to withdrawal seizures and delirium tremens (DTs), a state of severe confusion, agitation, fever and a racing heart that can be fatal without treatment.
- Benzodiazepines: stopping suddenly after regular use can cause severe anxiety, insomnia and seizures, which is why these medications are tapered slowly.
- Opioids: withdrawal is intensely unpleasant (aches, vomiting, diarrhoea, restlessness) and can cause dehydration. The greatest danger comes afterwards: tolerance drops quickly, so returning to use, especially with an unpredictable fentanyl supply, carries a high risk of overdose.
- Stimulants: the physical effects are milder, but the crash can bring deep fatigue, low mood and, for some people, thoughts of suicide that need close attention.
Safety first: do not stop drinking or stop benzodiazepines “cold turkey” on your own. Speak to a doctor before making any change. If someone is having a seizure, is severely confused, is hallucinating or cannot stay awake, call 911 now.
What happens in medical detox, step by step?
Detox at Sober Living follows a clear sequence: a pre-admission call, a full medical and psychiatric assessment on arrival, monitoring with vital signs and withdrawal scales, medication where needed, nutrition and sleep support, and a planned transition into therapy. Here is what each step involves.
- Pre-admission call. Our 24/7 admissions team asks what you use, how much, how often and when you last used; whether you have had withdrawal seizures or DTs before; your medical conditions, current prescriptions and mental-health history. This tells us whether our setting is safe for you or whether hospital-based withdrawal management should come first. We also verify insurance benefits and help with travel. You can read more about this on our intake process page.
- Medical and psychiatric assessment. On arrival, the medical team reviews your history, performs a physical examination, records baseline vital signs and may order a urine drug screen and blood work. A mental-health screen, including questions about mood, anxiety, trauma and suicide risk, identifies concurrent mental-health disorders that need to be treated alongside substance use.
- Vital signs and withdrawal scales. Blood pressure, pulse, temperature and breathing are checked regularly. For alcohol, staff use the CIWA-Ar (Clinical Institute Withdrawal Assessment for Alcohol, revised), which scores ten signs including nausea, tremor, sweating, anxiety, agitation, disturbances of touch, hearing and vision, headache and orientation. For opioids, the COWS (Clinical Opiate Withdrawal Scale) scores signs such as resting pulse, pupil size, yawning, runny nose, gooseflesh, bone and joint aches and stomach upset. Scores guide how often you are checked and when medication is given.
- Medications. Your physician prescribes based on your assessment. For alcohol withdrawal this commonly means a benzodiazepine given according to CIWA-Ar scores or on a set schedule. For opioid use disorder, many people start opioid agonist treatment such as buprenorphine-naloxone (Suboxone), which can later lead into our Sublocade program. Benzodiazepine dependence is usually managed with a gradual taper. Supportive medications may be used for nausea, diarrhoea, aches or sleep.
- Nutrition, hydration and thiamine. Withdrawal and heavy use often leave people dehydrated and undernourished. We encourage fluids, regular balanced meals and small frequent snacks if nausea is a problem. People withdrawing from alcohol are given thiamine (vitamin B1) to help protect against Wernicke’s encephalopathy, a serious brain condition linked to thiamine deficiency.
- Sleep and comfort. Poor sleep is one of the most common and persistent withdrawal symptoms. A quiet room, a predictable daily routine, gentle movement, breathing exercises and, where clinically appropriate, short-term medication help the body reset.
- 24/7 monitoring. Clinical staff are present around the clock. Check-ins become more or less frequent depending on your scores and how you feel, medication is adjusted as needed, and any sign of a complication is escalated immediately, including transfer to hospital if required.
- Transition into residential therapy. As withdrawal settles, you begin individual counselling, group sessions and skills work such as CBT and DBT, while the medical team keeps following you. Detox alone is not treatment: it clears the way for the psychological, emotional and social work that actually reduces the risk of relapse.

How long does detox take for different substances?
Most medically supervised detoxes last from a few days to about two weeks, but the answer depends on the substance, how much and how long it was used, and your overall health. The table below gives typical ranges used in clinical practice; your own timeline will be set by your physician.
| Substance | When withdrawal usually starts | Typical detox duration | Main clinical concerns |
|---|---|---|---|
| Alcohol | About 6 to 24 hours after the last drink | About 5 to 7 days; symptoms usually peak at 24 to 72 hours | Seizures, delirium tremens, dehydration; thiamine given routinely |
| Short-acting opioids (heroin, oxycodone, many fentanyl exposures) | Often 8 to 24 hours; fentanyl can be less predictable | Acute symptoms often last about 4 to 10 days; many people start opioid agonist treatment instead of stopping opioids entirely | Dehydration, severe discomfort, high overdose risk after tolerance falls |
| Long-acting opioids (e.g. methadone) | Often 1 to 3 days | Can last two weeks or longer; usually managed by slow taper or medication transition | Prolonged symptoms, cravings, overdose risk |
| Benzodiazepines | From about 1 day (short-acting, e.g. alprazolam) to a week or more (long-acting, e.g. diazepam) | Gradual taper over weeks to months, often continuing after the residential stay | Seizures if stopped abruptly, rebound anxiety and insomnia |
| Stimulants (cocaine, crystal meth) | Within hours to a day (the “crash”) | Acute crash lasts days; low mood, poor sleep and cravings can linger for weeks | Mostly psychological: depression, suicidal thoughts, cravings |
| Cannabis | Often within 1 to 2 days | Symptoms usually ease over about 1 to 2 weeks | Irritability, sleep problems, reduced appetite |

Alcohol detox in Toronto: what to expect
Alcohol detox usually means about a week of close monitoring, benzodiazepine medication guided by CIWA-Ar scores, thiamine and other vitamins, fluids and rest. The first three days are typically the most demanding, as tremor, sweating, anxiety, raised heart rate and poor sleep build and then begin to ease.
People with a history of heavy daily drinking, previous withdrawal seizures or DTs, or other health problems need particular caution. Once you are medically stable, you move into therapy that looks at why drinking took hold, how to manage cravings and triggers, and how to rebuild routines. Canada’s Guidance on Alcohol and Health (2023) is a useful reference for families trying to understand how much drinking carries risk.
Drug detox in Toronto: opioids, fentanyl, benzodiazepines and stimulants
Drug detox is shaped by the substance involved. For opioids, Canadian national guidance from CRISM advises against withdrawal management on its own because of the high risk of relapse and overdose afterwards; it recommends opioid agonist treatment, with buprenorphine-naloxone as a preferred first-line option for many people. People using fentanyl may need a carefully planned start on buprenorphine, sometimes with a low-dose approach, to avoid precipitated withdrawal.
Benzodiazepine dependence, whether from prescribed or non-prescribed use, is managed with a slow, individualized taper rather than rapid withdrawal. Stimulant detox focuses on rest, nutrition, mood monitoring and safety, since there is no medication specifically approved to treat stimulant withdrawal. Many people use more than one substance, and the protocol accounts for every one of them.
When is hospital-based withdrawal management the safer choice?
Some people need to go through withdrawal in a hospital, where emergency care and specialist teams are immediately available. A private residential centre is not the right first step for everyone, and we would rather say so than take a risk with your safety.
Hospital-based withdrawal management may be recommended if you have:
- A history of delirium tremens or withdrawal seizures combined with unstable medical conditions, such as advanced liver disease or significant heart disease.
- Signs of severe withdrawal right now: confusion, hallucinations, a seizure, a very fast heart rate or a high fever. This is an emergency: call 911.
- Heavy use of several sedatives together, such as alcohol with benzodiazepines or opioids.
- Pregnancy, where withdrawal must be coordinated with obstetric care.
- A recent head injury, serious infection or other acute illness.
- A mental-health crisis with immediate risk of suicide.
If any of these apply, our team will explain why, help you find hospital-based or public withdrawal management (ConnexOntario at 1-866-531-2600 can also help), and plan admission to residential treatment once you are medically stable.

What should I bring to medical detox?
Bring identification, your health and insurance cards, all current medications in their original containers, and about a week of comfortable clothing. Our admissions team will send an up-to-date list before you arrive.
- Ontario health card (OHIP) or provincial health card, and photo ID.
- Insurance or benefits card and any employee assistance program information.
- All prescription medications in the original pharmacy containers, plus a written list of doses and prescribers.
- Contact details for your family doctor, any psychiatrist or therapist, and an emergency contact.
- Comfortable, layered clothing for about a week, sleepwear and supportive shoes for walking and exercise.
- Alcohol-free toiletries (many mouthwashes, hand sanitizers and fragrances contain alcohol).
- Glasses, hearing aids, a CPAP machine or any other medical device you use.
- A journal or a book.
Leave at home: alcohol, non-prescribed drugs, valuables and large amounts of cash. Ask admissions about current guidelines for phones and other electronics.
How do I pay for medical detox in Ontario?
Private residential detox is usually paid through extended health benefits, employee assistance or disability plans, or privately. Publicly funded withdrawal management services also exist across Ontario and can be located through ConnexOntario, though availability and wait times vary.
We work with most major Canadian and international private insurers and benefit plans. Before admission, our team contacts your provider (with your permission) to confirm what is covered, so you know where you stand. Everything you share is kept confidential under Ontario’s health-privacy law, PHIPA. After detox, planning for aftercare and ongoing support begins well before discharge, and our Etobicoke location is about 15 minutes from Toronto Pearson for anyone travelling in.

Frequently asked questions
How long does medical detox take?
Most people complete the acute stage of detox in about 5 to 10 days. Alcohol detox is commonly around 5 to 7 days, opioid timelines vary with the type of opioid and whether you start opioid agonist treatment, and benzodiazepine tapers can take weeks to months. Your physician sets the timeline based on your assessment, and detox is followed by residential therapy rather than discharge.
Is alcohol detox dangerous?
It can be. After heavy, long-term drinking, withdrawal can cause seizures and delirium tremens, which can be fatal without treatment. Risk is higher if you have had these before or have other health problems. That is why alcohol detox should be medically supervised and why you should never stop suddenly on your own. Speak to a doctor first, and call 911 for seizures or severe confusion.
Can I detox at home?
For alcohol and benzodiazepines, detoxing at home without medical support is not safe for many people. Even for substances where withdrawal is rarely life-threatening, such as opioids or stimulants, home detox has high relapse rates, and a return to opioid use after tolerance falls greatly increases overdose risk. Talk to your doctor or our admissions team about the safest setting for you.
Do you use medication during detox?
Yes, when it is clinically appropriate. Medication choices depend on your assessment and may include benzodiazepines for alcohol withdrawal, buprenorphine-naloxone or other opioid agonist treatment for opioid use disorder, a gradual taper for benzodiazepine dependence, thiamine for people withdrawing from alcohol, and supportive medication for nausea, pain or sleep. Every prescription is reviewed by our medical team.
Can I detox from fentanyl at Sober Living?
Yes, where it is safe to do so. For most people with opioid use disorder, including fentanyl use, Canadian guidance recommends starting opioid agonist treatment rather than stopping opioids entirely, because detox alone carries a high risk of relapse and overdose. Our medical team can plan a buprenorphine start, which may later lead to monthly Sublocade injections, alongside residential therapy.
What happens after detox is finished?
You move straight into residential treatment, usually a 30-, 45-, 60- or 90-day program, with individual therapy, group work, CBT, DBT, family support and relapse-prevention planning. The medical team continues to follow you. Before discharge, we build an aftercare plan with ongoing check-ins, alumni support and connections to care in your home community.
Is detox at Sober Living confidential?
Yes. Your personal health information is protected under Ontario’s Personal Health Information Protection Act (PHIPA). We do not share information with your employer, family or anyone else without your consent, except where the law requires it. When we verify insurance benefits, we only do so with your permission.
