How Long Does Alcohol Stay in Your System? Blood & Urine
Determining exactly how long alcohol is detectable in the body depends on many variables, including which kind of drug test is being used. Alcohol can be detected for a shorter time with some tests but can be visible for up to three months in others. You can start to feel the effects of alcohol in a matter of minutes. When ingested, alcohol is rapidly absorbed from the stomach and small intestine into your bloodstream before it travels to the central nervous system (brain and spinal cord). As a central nervous system depressant, alcohol impairs the communication of messages in your brain, altering your perceptions, emotions, movement, and senses. When you drink alcohol, it is quickly absorbed in the stomach and small intestines.
Factors such as body fat percentage, gastric absorption, and genetic differences influence these variations. Women have less water in their bodies to dilute alcohol, causing their BAC to rise more quickly. Additionally, women produce lower levels of the enzymes needed to break down ethanol, leading to more alcohol stored in the body. Based on the standard alcohol detection window for hair testing, alcohol can be detected in a hair test up to 90 days after the last drink. Currently, there is a test that can detect alcohol use up to 80 hours, or 3 to 4 days, after the last drink a person had. If you’ve been drinking heavily and/or regularly, suddenly stopping or cutting back on alcohol can cause physical and psychological symptoms of withdrawal.

Your liver doesn’t register a glass of wine any differently from a mixed cocktail—it only processes alcohol. If one drink has a higher ABV than the other, your liver will have to work harder. A breath test uses breathalyzer devices sun rocks thc to measure a person’s BAC from their breath.
Recent Food Consumption
If a medical doctor performs the test, it’s often done with a blood sample. In a situation like a traffic accident or suspicion of driving under the influence (DUI), it may be a breath test. You have to pay attention to the type and amounts of alcohol you consume. As discussed, alcohol metabolization starts in the stomach. When it reaches the small intestine, it’s absorbed into your bloodstream.
- Breath tests for alcohol can detect alcohol within a shorter time frame, at about 4-6 hours.
- Alcohol can be detected in the hair for around 90 days after an alcoholic drink was consumed.
- 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.
- Lastly, if you eat before drinking, you’ll be able to keep your BAC lower since it prevents the alcohol from moving to the small intestine too quickly.
- A faster metabolism can help keep your BAC level lower, while a slower one will increase your BAC level.
- It’s characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences.
Can you “sober up” faster with food or coffee?
It’s recommended to wait 20 min after the last sip of the alcoholic drink for testing alcohol in oral fluids. In the U.S. alone, over 300,000 people are arrested annually for public intoxication, and more than 10,000 lives are lost each year due to drunk driving. As well, binge drinking can damage several organs, including the brain, gastrointestinal tract, liver, and heart. On average, the liver can process 1 ounce of alcohol every hour. It may be possible to detect it in the blood for several hours, and in the urine for several days.
This is because alcohol dehydrogenase (ADH) is lower in women than men (men have 40 percent more). A faster metabolism can help keep your BAC level lower, while a slower one will increase your BAC level. It tells the average amount of alcohol consumption over the three month period. Hair follicle tests detect alcohol up to three months after consumption. As you can see, EtG tests are more accurate than other tests.
Women have less dehydrogenase, which is a liver enzyme that breaks down alcohol, than men. There are instances where urine alcohol tests may be inaccurate. In some cases, alternative tests — such as a breath, hair, or blood test — may be more appropriate and valuable. Although urine tests are a relatively inexpensive and noninvasive way to test for alcohol, they may be inaccurate in some cases.
