On average, it takes about one hour for the body to eliminate one standard drink. Individuals who have higher tolerances to alcohol, such as people with alcohol addiction, may eliminate alcohol more quickly. In the short term, alcohol is processed through your liver in about an hour. Essentially, feeling “drunk” is when your liver becomes too overwhelmed to properly process alcohol, so it overflows temporarily into your bloodstream. This is what causes you to feel light-headed or tipsy after multiple alcoholic drinks. Alcohol can be detected in your body for hours, days, weeks, or even months after drinking.

- Regardless of how much you’ve had, it’s important not to get behind the wheel of a car (or a boat) when drinking.
- Binge drinking can lead to dangerously high BAC levels and severe health consequences, including alcohol poisoning.
This test is commonly used to see if a person has been drinking recently. The metabolism of alcohol has been studied in detail, but many factors determine how long alcohol shows up on a drug test and how long it takes to be eliminated from your body. Depending on the type of test used as well as your age, body mass, genetics, sex, and overall health, alcohol is detectable from 10 hours to 90 days.
Body Size
Consult a BAC chart to learn a healthy range for your situation. A study among morbidly obese adults in the U.S. found that those who had undergone bariatric surgery or gastric bypass took longer to become intoxicated. In contrast, those with extra weight but no surgery became intoxicated sooner.
If someone with alcohol problems also battles depression, their symptoms may worsen when drinking. Similarly, people with anxiety who drink heavily may experience stressful emotions that can cause a change in the stomach’s enzymes, which affects how a person breaks down alcohol. A healthy liver will eliminate one normal-sized alcoholic beverage in about one hour. After a night of heavy drinking your BAC may still be over the legal driving limit the next morning.
Time since the last drink
If your liver You Don’t Outgrow the Effects of an Alcoholic Parent has taken a hit from prolonged alcohol use, there are ways to give it — and the rest of your body — a break. Other factors affect the intoxication level that will cause BAC to rise more quickly and fall more slowly. Self-help support groups, such as Alcoholics Anonymous (AA), provide a safe and supportive environment to share stories and experiences.
How long does alcohol stay in your bloodstream?
It should not be used in place of the advice of your physician or other qualified healthcare provider. It should not be used in place of the advice of your physician or other qualified healthcare providers. Ethanol urine tests are not the most accurate, partly because the alcohol concentration in urine tends to lag behind the actual concentration of alcohol in the blood.
Since you metabolize alcohol over a set amount of time, drinking water between drinks allows your liver time to process the alcohol. While these techniques create the illusion of sobriety, they have no effect on BAC. Although eating before a night of drinking will slow down alcohol absorption, it will not keep you sober as you continue to drink. Eating after a few drinks will not reduce your level of intoxication because food does not have an effect on alcohol that has already been absorbed into the bloodstream.
How the body processes alcohol
A breathalyzer test measures the alcohol concentration in a person’s breath, known as breath alcohol content (BrAC). Frequently checked as part of routine breathalyzer testing, alcohol can be detected in the breath for up to 24 hours after the last drink. When someone is drinking alcohol particularly quickly, the liver cannot process all the alcohol at the same rate, so it remains in the body.
