It is FDA-approved for consumption (for adults over 21 in the U.S.) but is also regulated due to its potential for abuse. Alcohol is rapidly absorbed into the bloodstream, primarily through the small intestine, and its effects are felt within minutes. Drinking on an empty stomach results in faster absorption of alcohol, whereas having food in your how long does alcohol stay in your system stomach before consuming alcohol slows down absorption. Food assists with the dilution of alcohol and induces enzyme activity in the liver.

Long-term drinkers develop alcohol tolerance that allows their bodies to metabolize alcohol more quickly than nondrinkers or social drinkers.

Body Weight and Build

The body follows a pretty straightforward process when digesting and metabolizing alcohol. Therefore, the amount of time that a drink will stay in someone’s system has more to do with how much a person drinks than any other factor. Dr. Christine Traxler MD is a Minnesota-based Drug rehabilitation family practitioner and writer, having written dozens of medical texts, study guides, and scientific articles. She currently practices medicine in Kailua-Kona, Hawaii, and writes books in her spare time.
Why are alcohol blood tests used?
If someone drinks too much, too often, that person can develop liver disease, otherwise known as Cirrhosis. Genetics, alcohol tolerance, and the amount of alcohol consumed all affect the time it takes for alcohol to be processed in the body. Drinking water helps to replace some of the water lost during alcohol consumption, decreasing your chances of becoming dehydrated. Ensuring you stay hydrated can help reduce the severity or likelihood of you getting a headache or dry mouth, but it won’t speed up how quickly your body can get rid of the alcohol.

This means it takes longer for BAC to reach peak levels compared to drinking alcohol on an empty stomach, and may even lower the peak BAC. The same effect is seen in women, who have more subcutaneous fat than men. In short, it can take longer for the body to metabolize and eliminate the alcohol from our bodies. Depending on the urine testing kit being used, alcohol can be detectable in urine from 12 hours to 4 days.

A special test, known as the EtG test, is often given to confirm abstinence in a person who is required to maintain sobriety for legal or medical reasons. The EtG test measures a metabolite of alcohol known as ethyl glucuronide, which can be found in blood, hair, and nails, but it is typically done with a urine test. The EtG test can detect this alcohol metabolite for 3 to 5 days after consuming alcohol but does not accurately indicate if someone is currently intoxicated.
Factors that affect how long alcohol stays in your system
Unlike other blood tests, EtG tests can’t determine how much alcohol you’ve consumed. However, more advanced urine tests have much longer detection windows. These tests look for ethyl glucuronide (EtG), a by-product of ethanol metabolism, and glucuronide, a compound produced by the liver to bind to toxins to enable their excretion. Common misconceptions about water and alcohol elimination include believing that increased urination flushes alcohol faster. While you eliminate small amounts of alcohol through urine (2-10% of total consumption), the liver handles 90-98% of alcohol breakdown. Increased urination from water consumption doesn’t significantly change this ratio.
