The half-life of alcohol is four to five hours, which is the time it takes for your body to get rid of half of it. To completely eliminate alcohol, it takes about 25 hours, as it requires five half-lives. Mild detox symptoms may appear in just 2 to 6 hours after your last drink, and they usually peak in 1 to 3 days for a lighter drinker, but can last a week with heavy drinkers. Persistent withdrawal symptoms are quite rare, but they can last a month or more.
The length of time alcohol stays in your body depends on several factors. It takes time for the body to process alcohol, and on average, it takes about an hour to metabolize a standard drink. In terms of determining exactly how long alcohol can be detected in the body, it depends on many factors, including the type of drug test being used. Alcohol can stay in the hair for up to 90 days and can also be detected temporarily in saliva, sweat and blood.
For some examples of how long it will take your body to process various amounts of alcohol, see the table below. Controlling your alcohol consumption can be tricky, and there are a lot of rumors about how to sober up quickly and how you should have a clear mind before leaving the bar. It's common sense to avoid the driver's seat when the world is swimming. But what happens when you're a little drunk? How long does alcohol stay in your system? Even after the effects of alcohol have worn off, it can stay in the body for long periods of time.
Depending on the body's system, alcohol can last for different periods of time. For example, alcohol can be traced in saliva and breath up to 24 hours after drinking, while it can be detected in the bloodstream for up to 12 hours and in urine up to five days, depending on the test used. The most surprising of all is that alcohol can be found in strands of hair up to 90 days after the last drink. The body usually processes about one standard drink per hour. If you drink 5 standard drinks, it will take your body 5 hours to process alcohol.

Alcohol takes time to leave your system. On average, it takes about an hour for the body to eliminate a standard drink. People who have higher alcohol tolerances, such as people with alcohol addiction, can eliminate alcohol more quickly. Understanding the BAC and the speed at which the system metabolizes alcohol can help prevent the dangerous consequences of excessive alcohol consumption.
While individuals or online sources may recommend a variety of methods that they say will quickly remove alcohol from the body and help you pass a court-ordered or workplace alcohol test, nothing you do can speed up the process. Saliva tests can detect alcohol two hours after consumption and hair tests can detect alcohol for up to 90 days. For a person with alcoholism who can consume about 10 glasses of wine (about two bottles) in a day or on a binge, it may take up to 15 hours or more for the body to fully metabolize and remove the alcohol it consumes from the bloodstream. Alcohol or ethanol tests can detect alcohol metabolites in urine, breath, saliva, sweat, and blood for two to 80 hours. Popular wisdom falsely says that you have to drink coffee to be sober or take a cold shower, but none of these practices will diminish the degree to which alcohol affects you and caffeine can make things worse. Ethanol is an alcoholic beverage that can be detected in the urine up to an hour or two after alcohol has left the body. There's a fine line between heavy drinking and alcoholism, and it's not always easy to determine which side you're on. The two enzymes that are primarily responsible for alcohol processing are found in the liver, which break down ethyl alcohol (drinking alcohol) into acetaldehyde, which is then broken down into substances that the body can absorb.
The percentage of alcohol found in a person's bloodstream is known as blood alcohol concentration (BAC). The human body is very effective in processing alcohol, provided that alcohol is not consumed so quickly that alcohol poisoning occurs. Eliminating alcohol from your body requires understanding its dangers and avoiding a cycle of increasing tolerance, physical dependence, and ultimately a compulsive pattern of problematic drinking that culminates in addictions. Alcohol detox symptoms can be simply uncomfortable if you haven't had a drinking problem for a long time.
