How long does Alcohol stay in your Body?

Alcohol is a depressant that has a short life span in the body. Once alcohol has entered your bloodstream, your body will begin to metabolize it at a rate of 20 milligrams per deciliter (mg/dL) per hour. That means that if your blood alcohol level were 40 mg/dL, it would take about two hours to metabolize the alcohol.

Alcohol is metabolized at a constant rate, but some people may feel the effects of alcohol for longer amounts of time. That’s because blood alcohol concentrations can vary among people and situations. Blood alcohol concentration (BAC) refers to the amount of alcohol in your blood in relation to the amount of water in your blood. For example, if two people each have blood alcohol levels of 20 mg/dL, the alcohol will metabolize in about an hour in each person, but their BACs can be very different.

It’s also important to know how much alcohol is in your drink, because that will determine how long it takes to metabolize your drink. For example, some beers have a higher alcohol content, which affects how much alcohol you’re consuming from one drink.

The following are general estimates for how long it takes to metabolize different alcoholic beverages, though these times will vary depending on the amount of alcohol in the beverage:

Type of alcoholic beverage     Average time to metabolize

small shot of liquor                 1 hour

pint of beer                              2 hours

large glass of wine                  3 hours

a few drinks                            several hours

There are certain steps you can take to help reduce the effects of alcohol.

Food may help your body absorb alcohol.

Water can help reduce your BAC, though it will still take one hour to metabolize 20 mg/dL of alcohol.

Avoid caffeine. It’s a myth that that coffee, energy drinks, or any similar beverages alleviate intoxication quicker.

How is alcohol metabolized?

When you consume alcohol, it first enters the digestive system. Alcohol isn’t digested like food and other drinks, however. About 20 percent of the alcohol from a single drink moves directly to the blood vessels. From there, it’s carried to your brain. The rest of the 80 percent goes to your small intestine, then directly to your bloodstream.

The final step of the alcohol life cycle is its removal from the body through the liver. Any issues with your liver can slow down this process.

Urine vs. breath tests

Urine tests can detect alcohol long after you’ve had your last drink. These tests look for traces of alcohol metabolites. The average urine test can detect alcohol between 12 and 48 hours after drinking. More advanced testing can measure alcohol in the urine 80 hours after you drink.

Breath tests for alcohol can detect alcohol within a shorter time frame. This is about 24 hours on average. A small machine called a breathalyzer measures your BAC. Any number above 0.02 is considered unsafe for driving or other safety-based tasks.

Alcohol can stay in your hair for up to 90 days. It can also temporarily be detected in saliva, sweat, and blood.

Test     How long after drinking can it detect alcohol?

urine    12–48 hours

breath  24 hours

hair      90 days

Breastfeeding and alcohol

There’s a misconception that tracking the amount of alcohol you drink and the time your body takes to get rid of it can help keep breast milk safe. No amount of alcohol is safe to drink when you’re breastfeeding. Babies who are exposed to alcohol are at risk for decreased motor skills and other developmental delays.

While the Mayo Clinic says that alcohol takes a few hours to clear breast milk on average, the process varies in the same way as it does for women who aren’t breastfeeding.

If you do drink alcohol while breastfeeding, consider the following ways to keep your baby safe:

breastfeed before you have a drink

pump extra milk ahead of time so that you can feed your baby with expressed milk

wait 2-3 hours after a shot or a 12-ounce glass of beer or wine before breastfeeding again

Alcohol poisoning

Alcohol poisoning is an emergency medical condition. It occurs when a large amount of alcohol is consumed and your body can’t break it down quickly enough. Binge drinking is the most common cause of alcohol poisoning.

Symptoms include:

vomiting

reduced blood temperature

slower breathing

passing out

Oftentimes, a person with alcohol poisoning passes out before they realize what’s happened. If you suspect alcohol poisoning in a friend or loved one, call your local emergency services right away. To prevent choking from vomit, turn the person on their side. Never leave a friend with alcohol poisoning by themselves.

The quicker you seek help, the more likely you are to minimize potentially fatal complications, such as:

cardiac arrest

brain damage

seizure

asphyxiation

extremely low blood pressure
