How Long Does Alcohol Stay in Your System?

Alcohol affects everyone differently, and the amount of time it stays in your system depends on several factors. In this article, we'll discuss the various ways alcohol can be tested and how long it will show up on each test. We'll also explore the alcohol metabolization process, factors that influence it, and tips for sobering up if you've been drinking. Finally, we'll debunk common myths about getting sober quickly and discuss the importance of seeking help if you're struggling to control your alcohol consumption.

Struggling with Addiction? Get Help Now

You’ve taken a big gulp of wine. How long will it stay in your system?

The amount of time alcohol will show up on a test varies depending on the testing method used:

  • Blood: up to 12 hours 
  • Breath: up to 24 hours 
  • Breast milk: up to 3 hours 
  • Hair: up to 90 days 
  • Saliva: up to 48 hours
  • Urine: up to 5 days 

Alcohol is processed by your liver and other critical organs. They need time to do their work, and there’s nothing you can do to sober up faster. Your best bet: Don’t drink too much alcohol or stop drinking altogether. 

How Is Alcohol Metabolized?

Approximately 20% of the alcohol that an individual consumes quickly enters their bloodstream by being absorbed through the stomach.

Each sip of alcohol moves from your mouth to your stomach and out into the bloodstream. From there, it’s transformed into metabolites and then removed from your body.

A typical alcohol metabolization pathway looks like this:

  • Enzymes are released. Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) enter the bloodstream and break apart molecules of alcohol. 
  • Transformation begins. Alcohol becomes acetaldehyde. This substance is toxic, and it’s partially responsible for alcohol’s link to cancer risks. 
  • Transformation ends. Acetaldehyde becomes acetate, then water and carbon dioxide. 
  • The elimination process begins. Alcohol is removed through your breath and urine. 

Your liver works hard to remove alcohol from your body. This organ makes the enzymes that start the digestive process. But your liver works slowly. It can reduce your blood alcohol content (BAC) by about 0.015 per hour

Your alcohol metabolization rate is influenced by your sex, race, age, and weight. Your organ health matters too. But in general, metabolizing alcohol is a slow process. 

Can You Sober Up Quicker?

Once alcohol enters your body, there’s no way to make your body metabolize it more quickly. Your liver needs time, and you can’t push it. 

If you’re worried about passing an alcohol screening test after a big event, follow a few tips from food service workers:

  • Count. Keep track of how many drinks you’ve had in one sitting. Keep a mental note so you don’t drink too much.
  • Observe. Are you feeling tipsy? Stop drinking now. If you continue drinking, you’ll end up drunk.
  • Sip. Ask for a glass of water or another nonalcoholic drink to stay hydrated. Alternating alcoholic beverages with water can slow intoxication.
  • Eat. Food helps to slow alcohol absorption, and a snack keeps your mouth busy too. Food won’t help you sober up once you’re already drunk.
  • Skip. Don’t order a new drink every time your server checks on you. It’s better to nurse one drink over a longer period of time. 

If you’ve tried to limit how much you drink in one sitting and you can’t, don’t drink alcohol at all. Stick with water, juice, tea, or other tasty nonalcoholic beverages. 

Alcohol Testing: What You Should Know

A typical alcohol test happens “in the field.” You’ve been pulled over for erratic driving, and a police officer wants to determine if alcohol is to blame. These breath-based tests can detect your drinks for up to a day. 

Your employer might use blood, urine, or other tests to determine if you’ve been drinking recently. Timeframes on these tests are extended, and some forms that look for alcohol metabolites can spot your drinks for days. 

Plenty of get-sober-quick myths exist, and none of them work. You can’t get sober quickly by doing any of these:

  • Drinking coffee 
  • Eating a big meal 
  • Taking a cold shower
  • Throwing up 

Don’t try to cheat a test. Instead, look for ways to limit your drinking.

And if you can’t stop drinking on your own, get help from a qualified treatment program. If you want to stop drinking and aren’t able to, it’s a sign you need help.
