How Long Does Alcohol Stay in Your System? Testing Timeline

There are five different tests used for detecting alcohol in your body. If you’re more of a moderate to occasional drinker, you may find the hardest part of stopping drinking to be the social pressures. Of all your body’s organs, your liver takes the biggest hit when it comes to alcohol. Medications can significantly impact the way you metabolize alcohol. First, some medications compete for attention from your liver enzymes. This means those enzymes are not available to help with alcohol breakdown when you drink.

How frequently and how fast you drink, as well as the alcohol content in your beverage, can all influence how long ethanol stays in your system. Roughly 20% of the ethanol in liquor is absorbed into the blood from the stomach and the rest from the small intestine. The longer alcohol stays in the stomach, the longer it takes to be absorbed and the slower the rate of intoxication. Eating before drinking, and continuing to snack while you consume alcohol, will slow the absorption and reduce its impact, but prolong the detection period. Urine tests can detect alcohol long after you’ve had your last drink by testing for traces of alcohol metabolites. The average urine test can detect alcohol up to 12 hours after drinking.

Short-term risks

Alcohol can be detected in your body in five main ways, and the type of test used depends on the situation. Of course, we all want a simple, achievable number for how long we should abstain from alcohol in order for our bodies to fully heal from its effects. However, regular how long does alcohol stay in your system use of alcohol is not without risk, and the alcohol can remain in the system for quite a while, depending on several factors. Pumping breast milk will not eliminate alcohol from the milk any quicker. How long alcohol is detected in the system depends on what is being tested.

• A cocaine drug test (often called a drug screen) can detect the drug by using urine, blood, hair or saliva.
• That means you may feel soberer than you actually are, according to your blood alcohol content.
• On average, a person will metabolise the equivalent of one alcoholic drink per hour, but this can vary based on your weight, height, gender and body composition.
• Testing your blood for evidence of alcohol requires drawing the blood and testing it, typically in a lab.
• Breath tests are fast and typically easy when the right equipment, such as a Breathalyzer, is on hand.

A person’s body size and composition are also factors that can impact how fast alcohol is processed. Low-water fatty tissue cannot absorb alcohol to the extent that high-water muscle tissue can, meaning individuals with more body fat generally have higher BAC. Correspondingly, an individual that is extremely muscular but of shorter stature will have a higher BAC than someone taller than them of the same composition.

If you’re keeping up with this average (or less), the damage from alcohol is most likely minimal. Depending on how much you drink, it can take 6 to 24 hours for your body to metabolize alcohol. A saliva test measures the amount of alcohol in a person’s saliva. The detection window for saliva tests is usually shorter than for breath or blood tests. Alcohol detection times vary depending on the person and the test used. In most cases, alcohol can stay in your system for 6 to 72 hours.

If you have diabetes, a yeast infection or if you’re producing ketones like on the keto diet, your body can naturally create enough ethanol to trigger a false positive. This is especially true if the urine sample is left out at room temperature, where the microorganisms can continue to ferment glucose and create more alcohol. When you take a test that measures how much alcohol is in your system, it’s not the total amount of alcohol drunk that’s measured. Alcohol tests measure your blood/breath alcohol concentration (BAC) levels. Your BAC shows the amount of alcohol in your bloodstream or breath, shown by how much ethanol (in grams) is in 100 millilitres of blood or 210 litres of breath.

Saliva Tests (12 to 24 hours)

Alcohol is transported throughout the body through the blood, and as a result there are many possible tests to detect its presence. To see how long various tests will detect alcohol, please consult the table below. However, the biomarkers — or physical evidence — that you consumed alcohol can be present for days or even weeks and are detectable by other specialty tests. After a drink, this is how long can you expect the alcohol to stay in your blood, urine and other areas of the body. The liver breaks alcohol into ketones at about 0.015 g/100mL/hour (reduces BAC by 0.015 per hour).

The amount of alcohol in various alcoholic beverages can be seen in the table below. A third enzyme, catalase, which is present in cells throughout the body, also metabolizes a small amount of alcohol. These scientists believe that the presence of tetrahydroisoquinolines can be used to determine whether someone is an addicted drinker or a social drinker. The factors that impact how long alcohol stays in your system are at play again here. These factors can also affect how fast you’ll feel the effects of alcohol.

However, more advanced testing can measure alcohol in the urine 24 hours after drinking. If someone’s blood alcohol content is 0.08, it would take about five hours and 20 minutes for the body to metabolize the alcohol. It typically takes a person with a BAC of 0.20 anywhere from 12 to 14 hours to reach sobriety. Women have less dehydrogenase, an enzyme that breaks down alcohol in the stomach. This contributes to women reaching higher blood alcohol levels than men despite drinking the same amount of alcohol.

• Carbonated beverages, such as champagne or a whiskey mixed with soda, are absorbed faster.
• If you don’t have enough ADH or ALDH, your stomach will send the alcohol directly to the small intestine.
• Most of the alcohol you consume is metabolized in the liver, but about 5% of the alcohol you drink is excreted by the body through sweat, breath, urine, feces, and saliva.
• For most people, alcohol is absorbed into the system more rapidly than it is metabolized.
