Alcohol Poisoning: How to Recognise It and What to Do in an Emergency

What Is Alcohol Poisoning?

Alcohol poisoning, also known as acute alcohol intoxication or alcohol overdose, occurs when a person consumes a toxic amount of alcohol in a short period of time. It is a medical emergency. When the body cannot process alcohol fast enough, the blood alcohol concentration (BAC) rises to a level that begins to interfere with basic bodily functions, including breathing, heart rate, and body temperature regulation.

Alcohol poisoning is not the same as being very drunk. It represents a point at which the body is in genuine physiological distress and can be fatal without prompt intervention. Understanding the difference, and knowing how to respond, is knowledge that can quite literally save a life.

It affects people of all ages, though it is most commonly associated with binge drinking episodes. Young adults, in particular, are at elevated risk due to social and cultural pressures around drinking, relative inexperience with alcohol, and the prevalence of drinking games and high-alcohol beverages in social settings.

How Alcohol Affects the Body

When you drink alcohol, it is absorbed through the stomach and small intestine into the bloodstream. The liver metabolises alcohol at a broadly consistent rate, roughly one standard drink per hour in most adults, though this varies significantly based on body weight, sex, age, food consumption, liver health, and individual genetic factors.

When alcohol is consumed faster than the liver can process it, the excess circulates in the blood and reaches the brain. Alcohol is a central nervous system depressant. At lower concentrations it produces feelings of relaxation and reduced inhibition. At higher concentrations it begins to impair coordination, judgement, and speech. At toxic concentrations, it suppresses the brain stem functions that control breathing, heart rate, and the gag reflex.

The gag reflex is particularly important in the context of alcohol poisoning. When this reflex is suppressed, a person who vomits can inhale the vomit into their lungs, leading to asphyxiation. This is one of the primary causes of death in alcohol poisoning cases.

Crucially, a person's BAC can continue to rise even after they have stopped drinking, as alcohol already in the stomach continues to be absorbed. Someone who appears to be merely very drunk at the time they stop drinking may reach dangerous BAC levels in the hour or so that follows.

Signs and Symptoms of Alcohol Poisoning

Recognising the signs of alcohol poisoning is essential. The following symptoms indicate a serious and potentially life-threatening situation.

Confusion or stupor is often one of the first indicators. A person who is severely confused, barely responsive, or seemingly drifting in and out of consciousness is showing warning signs that should not be dismissed as merely being very drunk.

Vomiting while unconscious or semi-conscious is a severe danger. A person who cannot sit upright and control their own airway is at immediate risk of choking on their own vomit.

Seizures can occur as a result of toxic blood alcohol levels or the accompanying dehydration and electrolyte imbalance.

Slow or irregular breathing is a critical warning sign. Normal breathing is approximately 12 to 20 breaths per minute. Fewer than eight breaths per minute, or gaps of more than ten seconds between breaths, constitute a medical emergency.

Blue-tinged or pale skin, particularly around the lips or fingertips, indicates that the body is not receiving adequate oxygen. This is a sign of severe distress.

Low body temperature (hypothermia) can develop rapidly, particularly in cold environments. A person with alcohol poisoning may feel cold to the touch and may stop shivering, which would normally be the body's response to cold.

Unconsciousness from which the person cannot be roused is a clear emergency. If you cannot wake someone up, do not assume they are sleeping it off. They need immediate medical attention.

The Recovery Position and Why It Matters

If a person is unconscious but breathing, placing them in the recovery position is one of the most important things you can do while waiting for emergency services. The recovery position keeps the airway open and reduces the risk of the person inhaling vomit.

To place someone in the recovery position, kneel beside them. Place the arm nearest to you at a right angle to their body, elbow bent with the palm facing upward. Bring their other hand to their cheek and hold it there. Use your other hand to pull the knee farthest from you upward until the foot is flat on the floor. Gently roll the person toward you onto their side, using their bent knee as a lever. Adjust the top arm so that the palm is still under their cheek. Make sure the top knee is bent at a right angle to prevent the person rolling forward. Tilt their head back gently to open the airway.

Once in the recovery position, monitor their breathing continuously until emergency services arrive. Do not leave them alone.

What to Do If You Suspect Alcohol Poisoning

If you believe someone has alcohol poisoning, call emergency services immediately. In the United Kingdom, call 999. In Australia, call 000. In the United States and Canada, call 911. In most of Europe, call 112. Do not delay making this call out of concern about getting someone in trouble. Emergency responders are there to save lives, not to pass judgement.

While waiting for emergency services, stay with the person. Do not leave them alone under any circumstances. If they are conscious, try to keep them awake and upright or sitting forward. If they are unconscious or semi-conscious, place them in the recovery position as described above.

Try to gather information that will be useful for the paramedics: what they have been drinking, how much, over what period of time, and whether they have taken any other substances including prescription or over-the-counter medication. If possible, keep any bottles or containers nearby for the paramedics to see.

Keep the person warm. Alcohol causes blood vessels to dilate near the skin, which accelerates heat loss. A person with alcohol poisoning can develop dangerous hypothermia quite quickly, particularly outdoors or in a cold environment. Cover them with a coat or blanket.

Do not give them food, water, or coffee. These will not speed up the metabolising of alcohol and may cause them to vomit, which creates a choking risk. Do not give them any other substances.

Do not put them in a cold shower. The sudden cold can cause a shock response and will not sober them up.

Common Myths That Cost Lives

A number of widely believed myths about alcohol intoxication can have fatal consequences if acted upon.

The most dangerous myth is that someone who is very drunk should be left to "sleep it off." A person whose BAC is rising can slip from unconsciousness into a life-threatening state while sleeping. People have died from alcohol poisoning while others assumed they were sleeping normally and did not seek help.

The idea that coffee or food will sober someone up is also false. There is nothing that meaningfully speeds up the liver's metabolism of alcohol. Time is the only effective remedy for alcohol intoxication, and in a poisoning situation, time may not be available.

Some people believe that walking someone around will help. It will not speed up the processing of alcohol and risks falls and further injury in a person with severely impaired coordination.

The belief that you should not call an ambulance because you or the person who is ill will "get in trouble" is a myth with potentially fatal consequences. In many countries, Good Samaritan laws provide legal protection for people who call for medical help in good faith during a drug or alcohol emergency. Even where such protections are less explicit, saving a life is always the right priority. Emergency responders understand the circumstances in which they are called, and their focus is on medical care, not enforcement.

Factors That Increase the Risk

Certain factors significantly increase the risk of alcohol poisoning, and being aware of them helps in assessing risk situations.

Drinking on an empty stomach causes alcohol to be absorbed much more rapidly into the bloodstream. A person who has not eaten before drinking can reach dangerous BAC levels with fewer drinks than someone who has had a meal.

Mixing alcohol with other substances, including prescription medications, recreational drugs, and even some over-the-counter medicines, can dramatically amplify the effects of alcohol and increase the risk of overdose. Sedatives, opioids, and antihistamines are among the substances with particularly dangerous interactions.

High-strength alcoholic drinks and large volumes consumed rapidly, as in drinking games or competitions, concentrate the intake in a short window that the liver cannot keep pace with. Pre-mixed spirits and cocktails can also obscure the true amount of alcohol being consumed.

Smaller body weight generally means faster increases in BAC for the same amount of alcohol. Young people who are of smaller stature, or who have less experience with alcohol and therefore less awareness of their own tolerance, may reach dangerous levels more quickly than they expect.

Looking After Yourself and Others in Social Settings

Being the person in a social group who is watching out for others is not always easy, but it is genuinely important. Looking out for signs that someone is deteriorating beyond ordinary drunkenness, staying with them if they become unwell, and being willing to call for help even in social situations where that feels awkward, is how lives are saved.

Agree on a system with your friends before a night out. Designate someone who will stay relatively sober, make sure everyone knows where they are going, and establish a simple check-in arrangement so that no one ends up in difficulty alone.

If you are concerned about your own relationship with alcohol, or about that of a friend, there are resources available in most countries that offer confidential support and guidance without judgement. Alcohol charities, GP services, university health centres, and national helplines are all accessible starting points.

After an Alcohol Poisoning Incident

If someone you know has experienced alcohol poisoning and received medical treatment, it is worth following up with care and support after the immediate emergency has passed. The experience can be frightening and disorienting, and many people feel embarrassed or ashamed in the aftermath.

Approaching the conversation with compassion rather than judgement is more likely to open up a productive dialogue about what happened and whether any changes to drinking habits might be beneficial. In some cases, an episode of alcohol poisoning is a signal that a person is struggling with something beyond a single bad night, and connecting them with appropriate support can make a meaningful long-term difference.

Understanding alcohol poisoning, recognising its signs, and knowing how to respond correctly are skills that belong in every young adult's repertoire. The knowledge is simple to acquire and can make the difference between life and death.
