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

Too many alcoholic drinks doesn’t just contribute to not-fun next-day effects like a raging hangover. It’s also tied to mental health conditions like depression and anxiety. Your body processes alcohol at the rate of around one standard-sized drink per hour, but booze can be detected in your blood, breath, and pee for a long time afterwards. A urine test can usually pick up alcohol up to 24 hours after drinking, but a 2007 study showed that some tests can potentially detect alcohol for much longer.

After a drink, this is how long can you expect the alcohol to stay in your blood, urine and other areas of the body. If you’re struggling with alcohol addiction, seeking professional treatment can be the first step toward a healthier and happier future. Heavy drinkers can also experience more severe health consequences due to heavy drinking habits. A BAC of .08% is equivalent to four drinks consumed by a 160-pound person in one hour. Those who smoke cannabis daily can have it detected for up to 30 days.

How Long Does It Take Your Liver to Detox From Alcohol?

Therefore, it is important to purchase an accurate BAC tester to objectively verify whether your BAC is low enough to drive prior to hitting the road. Because there is no safe amount of alcohol for babies, doctors recommend breastfeeding prior to drinking or pumping extra milk beforehand. The Mayo Clinic suggests waiting at least two to three hours after a shot, can of beer, or glass of wine, before breastfeeding. The belief that breastmilk can be cleared of alcohol with the “pump and dump” method is false. As long as there is alcohol in the body, it will be present in breastmilk. Each woman is different and will process alcohol at varying rates of times.

Under most circumstances, the legal limit you must remain below to avoid arrest of 0.08%. Having the smell of alcohol does not mean you have passed that limit, and only the alcohol content in your bloodstream can determine that. Most people stop having withdrawal symptoms four to five days after their last drink. Assuming that an individual drank 12 oz of a 40% ABV beverage, they would get drunk at an 8-fold quicker rate than if they drank 12 oz of a 5% ABV beverage. Whenever factoring in clearance, it is important to consider the potency of the alcohol you consumed. A higher potency will take longer to clear from your system because the beverage contained a greater amount of total alcohol.

Rate of Metabolism

You can still pursue therapy and support groups as you go through withdrawal. Due to portability, ease-of-use, and accuracy – many people have purchased their own breathalyzers to know whether they are below the BAC threshold of 0.08 and are “legal” to drive. In rare cases, results on a breathalyzer test may be subject to inaccuracies as a result of a particular environmental setting (e.g. presence of volatile fumes) and/or programming.

Characteristics like age, weight, sex, and medical history all play a part in how concentrated the alcohol in your blood is after drinking also known as blood alcohol concentration or BAC. However, virtually all humans metabolize alcohol at a constant rate of 20 milligrams per deciliter (mg/dL) per hour, or 0.015 BAC every hour. This means that a blood alcohol level of 80 mg/dL will take four hours to metabolize and a BAC of 0.08 will take approximately 5.33 hours before there is no measurable alcohol in the blood. How long alcohol stays in your system depends on a number of factors. A big concern that many people have after a long night of drinking is how long alcohol will remain in their system. On average, it takes about one hour to metabolize one standard drink.

Strength of drink

Peak BAC could be as much as 3 times higher in someone with an empty stomach than in someone who has consumed food before drinking. Eating regular meals and having snacks while drinking can help induce enzyme activity in the liver and slow the rate at which alcohol is absorbed. Once a person’s blood-alcohol levels go above .05% to .055%, alcohol’s negative effects start to increase.

After you’ve drained your glass, your body immediately works to get rid of it. Chances are you’ll still be feeling it for about an hour, maybe even 2 hours depending on how your body metabolizes alcohol. One phase is the acute form of alcohol poisoning caused mainly by binge drinking.

High levels of dopamine are what give cocaine its addictive potential.

One cup of beer may stay in one person’s system longer than it will for someone else with a different weight. 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. Also known as your blood alcohol concentration, or BAC, .08 percent counts as drunk from a legal perspective. Once your BAC hits .08 percent, you’ll have the tell-tale signs of being drunk.

So feelings of calm, happiness, and relaxation start to turn into depression, irritability, and disorientation. At around .08% to .09%, sense of balance is off and motor skills are impaired. Some people may also begin vomiting at this level due how long does alcohol stay in your system to excess alcohol in the blood and the body’s inability to metabolize the alcohol fast enough. In the United States, someone is considered to be legally intoxicated and prohibited from driving a vehicle if their BAC level is 0.08% or greater.
