Key Takeaways:
- Alcohol typically metabolizes at about 0.016% BAC per hour, meaning it can take several hours to fully clear from your system even after you feel sober.
- Detection windows vary by test type—blood (up to 12 hours), breath (12–24 hours), urine (10–12 hours or 3–5 days with EtG), saliva (24–48 hours), and hair (up to 90 days).
- Multiple factors influence how long alcohol stays in your body, including body weight, liver health, sex, medications, hydration, and genetics.
- Can you speed up alcohol elimination? No—coffee, cold showers, hydration, or exercise cannot accelerate metabolism. Only time allows the liver to process alcohol.
- Long-lasting alcohol in your system increases risks such as impaired driving, health complications, liver disease, and signs of alcohol use disorder, highlighting when professional support may be needed.
Knowing how long alcohol stays in your system isn’t just trivia—it’s a question that can affect your safety, health, and daily life. Whether you’re wondering how long until you feel sober again, how soon you could pass an alcohol test, or how your body metabolizes alcohol, it’s important to understand the basics of what happens when you drink.
At Voyager Recovery Center, we help people understand the effects of drinking alcohol, how the body processes alcohol, and what that means for alcohol use disorder, mental health, and recovery. This guide explains everything in plain language—no medical jargon, no judgment: just the facts you need to make informed decisions about alcohol use.
How Your Body Processes Alcohol
When you take a drink, the ethanol in it enters your stomach and is then absorbed through your small intestine into your bloodstream. From there, it travels to your brain and other organs, affecting everything from movement and balance to judgment and mood.
The liver then begins its job: Enzymes like alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) convert ethanol first into acetaldehyde (a toxic by-product), and then into harmless substances that your body can remove via urine, sweat, breath, and feces.
Although you might feel sober after a few hours, your body is still working. On average, a healthy adult’s liver can lower blood alcohol concentration (BAC) at about 0.016% per hour, meaning if your BAC was 0.08%, it may take around five hours to reach 0.02% and longer to reach 0.00%.
How Long You Feel the Effects of Alcohol
You usually start feeling alcohol’s effects within minutes of your first sip. As your BAC rises, you may notice:
- Relaxation or a sense of euphoria
- Slurred speech or loss of coordination
- Impaired judgment and delayed reaction times
These effects depend on the amount of alcohol consumed, how fast you drink, and whether your stomach is empty. Binge drinking—consuming several drinks quickly—can raise your BAC dangerously high and increase the risk of alcohol poisoning or blackouts.
Even after the buzz fades, alcohol remains in your body as it continues to metabolize over time.
How Long Alcohol Stays Detectable
The amount of time alcohol remains detectable depends on the type of test, your health conditions, and how much and how often you drink. Here’s a general idea of what to expect:
- Blood tests: Alcohol can be detected for up to 12 hours after your last drink.
- Breath test (breathalyzer): Breath tests detect alcohol for 12–24 hours, depending on BAC levels and the amount of alcohol consumed.
- Urine tests: Standard urine tests can detect alcohol for 10–12 hours, while EtG/EtS tests can identify use for 3–5 days by measuring metabolites.
- Saliva tests: May detect alcohol for 24–48 hours after use.
- Hair tests: In heavy drinkers, hair follicle tests can show traces of alcohol or ethyl glucuronide for up to 90 days.
Because everyone’s metabolic rate is different, think of these as time frames, not exact numbers.

Why Alcohol Lasts Longer for Some People
Your detection window depends on several personal factors that influence how your body metabolizes alcohol:
- Body weight: People with higher body weight usually have lower BAC levels after the same amount of alcohol.
- Body fat: Alcohol doesn’t absorb well into fat, so individuals with more body fat may retain alcohol longer.
- Liver function: Poor liver health or liver disease slows down alcohol metabolism and increases the half-life of alcohol in the system.
- Sex: Women generally process alcohol more slowly than men due to lower water content and fewer enzymes.
- Food intake: Eating before or during drinking slows absorption, reducing BAC spikes.
- Hydration: Drinking water can ease dehydration, but it won’t flush alcohol out faster.
- Medications: Certain prescriptions affect liver enzymes, changing how the body processes ethanol.
- Genetics: Some people naturally produce less alcohol dehydrogenase, which means alcohol stays in their bodies longer.
If you frequently drink or struggle with substance use, your liver function and metabolism may be slower, extending your alcohol detection times.
Health and Safety Risks
Understanding how long alcohol stays in your system helps you avoid unnecessary risks. Even when you think you’ve sobered up, your BAC might still be elevated.
Risks include:
- Impairment while driving or operating machinery
- Failing a breath test or urine test during workplace or legal screenings
- Long-term damage from excess alcohol, including liver disease and other health conditions
- Greater risk of alcohol addiction and mental health struggles over time
Over time, chronic alcohol consumption can lead to fibrosis, cirrhosis, and other serious liver conditions. Excessive drinking also disrupts sleep, increases anxiety, and affects your body’s ability to detox naturally.
Can You Speed Up the Process?
No matter what you’ve heard, there’s no quick fix to get alcohol out of your system. Despite myths, the following won’t help you sober up faster:
- Coffee
- Cold showers
- Exercise or sweating
- Drinking more water
Your body needs time to process alcohol through the liver. The only real solution is to stop drinking and let your body do its work naturally. The half-life of ethanol doesn’t change, no matter what you eat or drink afterward.
When Drinking Becomes a Problem
If you or a loved one finds it hard to stop drinking—or if your drinking alcohol leads to blackouts, missed responsibilities, or withdrawal symptoms—it might be a sign of alcohol abuse or alcohol use disorder.
Watch for these warning signs:
- Drinking to escape stress or numb emotions
- Needing more alcohol for the same effect
- Feeling guilty or anxious about alcohol consumption
- Experiencing tremors, insomnia, or nausea after stopping
- Struggling with work, relationships, or mood swings
At Voyager Recovery Center, we know these struggles can feel overwhelming—but help is always available.
