Symptoms of Alcohol Intoxication: What to Know

Alcohol intoxication, commonly referred to as being “drunk,” occurs when a person consumes more alcohol than their body can process. As blood alcohol concentration (BAC) rises, it begins to affect the brain and body in predictable ways. Recognizing the symptoms of alcohol intoxication is important not only for personal awareness but also for keeping friends, family, and community members safe.

Early Symptoms of Alcohol Intoxication

At lower levels of intoxication, a person may show mild changes that can be easy to overlook:

• Lowered inhibitions – behaving more freely or impulsively than usual
• Mild euphoria – feeling relaxed or happier than normal
• Slight impairment of coordination – difficulty with balance or clumsiness
• Slurred speech – early signs of slowed brain-to-muscle communication

Moderate Symptoms

As alcohol continues to affect the central nervous system, the symptoms become more pronounced:

• Poor judgment – risky decisions or lack of awareness of danger
• Delayed reaction times – slower responses to questions or situations
• Noticeable loss of balance – stumbling, swaying, or difficulty walking
• Blurry vision – inability to focus or track objects clearly
• Increased emotional changes – from exaggerated happiness to irritability or sadness

Severe Symptoms of Alcohol Intoxication

At higher levels of intoxication, alcohol can cause dangerous or life-threatening effects:

• Confusion or stupor – inability to stay awake or respond coherently
• Vomiting – risk of choking if the person is unconscious
• Seizures – in severe cases due to changes in brain activity
• Irregular or slow breathing – fewer than eight breaths per minute may signal alcohol poisoning
• Blue-tinged or pale skin – sign of oxygen deprivation
• Unresponsiveness – inability to wake the person even with stimulation

When to Seek Emergency Help

Severe intoxication can progress to alcohol poisoning, a medical emergency. Call 911 immediately if someone:

• Is unresponsive or hard to wake
• Has slow or irregular breathing
• Has seizures
• Shows signs of hypothermia (low body temperature)

Frequently Asked Questions (FAQ)

Can you die from alcohol intoxication?

Yes. Severe intoxication can lead to alcohol poisoning, which may cause respiratory failure, choking, seizures, or death if untreated. Immediate medical attention is critical.

What’s the difference between alcohol intoxication and alcohol poisoning?

Alcohol intoxication refers to the range of symptoms caused by drinking, from mild impairment to severe confusion. Alcohol poisoning is a medical emergency that happens when BAC is dangerously high and the body can no longer function normally.

How long do the symptoms of alcohol intoxication last?

It depends on how much alcohol was consumed, body weight, metabolism, and other factors. Symptoms may last a few hours but can extend longer if large amounts of alcohol were consumed.

At what BAC do symptoms appear?

For most people, symptoms of alcohol intoxication begin around a BAC of 0.02% to 0.03% (mild effects). Severe symptoms and risk of alcohol poisoning usually appear at 0.15% or higher.

Can you sober up quickly?

No. Coffee, cold showers, or exercise may make someone feel more alert, but they do not reduce BAC. Only time allows the body to metabolize alcohol.

Why Recognizing the Symptoms Matters

Understanding the symptoms of alcohol intoxication helps reduce risks such as drunk driving, accidents, or alcohol poisoning. Whether at a party, a bar, or a family gathering, being aware of the warning signs allows you to step in, support safer choices, and call for medical help when necessary.
