How Long Does Alcohol Intoxication Last? Duration, Factors, and Recovery

Understanding Alcohol Intoxication

Alcohol intoxication occurs when the central nervous system is impaired by ethanol, leading to symptoms such as slurred speech, impaired judgment, loss of coordination, and slowed reaction time. The duration of intoxication depends largely on blood alcohol concentration (BAC) and how quickly the body processes alcohol.

How Long Does Alcohol Intoxication Last?

On average, alcohol intoxication can last anywhere from 2 to 8 hours. In general, the body metabolizes one standard drink (roughly 14 grams of pure alcohol) per hour. However, this rate can vary, meaning intoxication may last longer for some individuals.

The peak effects of intoxication usually occur within 30 to 90 minutes after drinking. Once drinking stops, symptoms gradually decrease as alcohol is metabolized, though drowsiness, dehydration, and cognitive impairment may linger into the next day.

Factors That Influence Duration

Several factors determine how long intoxication lasts:

• Amount of alcohol consumed: Larger quantities extend intoxication.
• Body weight and composition: People with lower body mass usually feel intoxicated longer.
• Metabolism: Faster metabolic rates reduce intoxication duration.
• Food intake: Drinking on an empty stomach leads to faster intoxication.
• Tolerance: Frequent drinkers may recover quicker, though liver damage over time can impair alcohol processing.

When Does Intoxication Become Dangerous?

Mild intoxication typically resolves within several hours, but severe intoxication can be life-threatening. A BAC above 0.30% may result in loss of consciousness, respiratory depression, or even death. Anyone who is unresponsive, breathing irregularly, or has seizures after heavy drinking needs immediate medical attention.

Tips for Recovery

• Hydrate with water or electrolyte drinks to counteract dehydration.
• Rest in a safe environment to allow the body to metabolize alcohol.
• Eat light, nutritious foods to support recovery.
• Avoid caffeine or “sobering up” myths—only time reduces intoxication.

Key Takeaway

Alcohol intoxication typically lasts a few hours but can stretch into the next day depending on how much you drink and personal factors. Since only time can fully sober you up, pacing your drinking, staying hydrated, and knowing your limits are the safest strategies to minimize risk.
