How Long Does Alcohol Stay in Your System? Blood & Urine

Blood alcohol content (BAC), also known as a blood alcohol level, is the amount of alcohol in your blood. 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.

If you are concerned about how long alcohol may be detectable in your blood, it may be time to seek help. However, the safest option for nursing people is not to drink any alcohol. You may have heard it is okay to drink alcohol while breastfeeding or chestfeeding a baby in certain circumstances. Blood alcohol concentration (BAC) refers to the amount of alcohol in your blood to the amount of water in your blood. The results may also indicate “positive” or “negative,” meaning you did have alcohol in your blood or you had no alcohol in your blood, respectively.

Common Myths About Sobering Up

One of the primary differences is that blood tests are a lot more reliable and accurate. Breathalyzers can produce false positives because the test relies on a person blowing into the resting device. This can bring in alcohol that was in the person’s mouth, not their blood, and can cause false positives and reads that are too high.

Nothing you do will speed up the elimination process, including drinking coffee, drinking water, taking a shower, or even vomiting. Therefore, even if you consume only one drink per hour, your blood alcohol concentration (BAC) will continue to increase. If you drink more than one per hour, it rises much more rapidly.

In moderation, alcohol can be OK for people old enough to legally drink. However, if you drink excessive amounts of alcohol in a short amount of time and/or drink large amounts frequently, your health can be at risk. If you’re concerned about your drinking habits, reach out to your healthcare provider or a specialist. Together, you can come up with a plan to improve your habits and health. Regardless of how fast your body absorbs alcohol, it eliminates it at the average rate of 0.016 BAC per hour.

If you’ve been drinking heavily and/or regularly, suddenly stopping or cutting back on alcohol can cause physical and psychological symptoms of withdrawal. The severity will depend on how long you’ve been using alcohol and how much you normally drink. In severe cases, you can experience a possibly life-threating type of alcohol withdrawal known as delirium tremens (or DTs), which can occur from two days to up to a week after your last drink. The above times reflect the metabolism rate of a healthy, functioning liver.

However, the affect that one drink will have on the percentage of alcohol in your blood can vary greatly according to a complex group of personal factors. Consuming large amounts of alcohol in a short period of time can result in alcohol poisoning, which is a medical emergency. According to the Centers for Disease Control and Prevention, an average of six people per day die of acute alcohol poisoning. Genetic, environmental, and physical and mental health factors control alcohol metabolism and elevate your blood alcohol content — the percentage of alcohol in the blood.

From there, it hits your bloodstream and your brain, and you start feeling its effects. The organ breaks down the alcohol into acetaldehyde, a chemical the body recognizes as toxic. Acetaldehyde metabolizes into carbon dioxide, which the body can eliminate.

Why are alcohol blood tests used?

Blood alcohol level (BAC), is the amount of alcohol in your blood that develops from drinking beverages that contain alcohol. Levels can range from 0% (no alcohol) to over 0.4% (a potentially fatal level). Knowing how long alcohol (ethanol) remains in your system is important for avoiding dangerous interactions with medications as well as impairments in your physical and mental performance. While alcohol is not considered a controlled substance under the Controlled Substances Act (CSA), it is illegal to sell or serve to anyone under the age of 21 in the United States. Alcohol blood tests and breathalyzers are both used to measure intoxication, but there are key differences. When it comes to “passing” an alcohol test, there’s no guarantee.

But a 2007 study published in the journal Alcohol and Alcoholism found that ETG tests failed to detect alcohol more than 26 hours after consumption. 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. However, more advanced testing can measure alcohol in the urine 24 hours after drinking. 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.

1. However, different beers and wines can contain different percentages of alcohol.
2. The results are typically reported in the percentage of blood alcohol content (BAC) — for example, 0.03% BAC.
3. Drinking stronger alcoholic beverages can accelerate the absorption rate.
4. When you consume alcohol, the metabolising process is done primarily by your liver.

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. Saliva tests can detect alcohol two hours after consumption, and hair tests can detect alcohol for up to 90 days.

Can you “sober up” faster with food or coffee?

Urine tests can detect alcohol for between 12 hours and 24 hours. This length of time usually depends on how recently and how much you drank. Breathalyzers can detect alcohol in your breath up to 24 hours after drinking. Alcoholic beverages such as beer, wine and liquor break down differently in each person’s body.

False Positives

Although the legal limit for driving is .08% in all states, penalties vary sharply. Plus, in some states, drivers under the age of 21 have a different, much lower, legal BAC percentage threshold. There are several tests to measure the level of alcohol in your blood.

The use of some drugs, including prescription medications, can affect how alcohol is metabolized in the body. One of the most important factors that determine how long it takes for alcohol to leave the blood is how much you’ve had to drink. Alcohol can stay in the blood for about 12 to 24 hours on average, depending on how much you had to drink and various other factors. The rate at that alcohol can stay in your system depends on various factors. Keep your consumption to a few drinks per week, and avoid excessive consumption.
