The speed of alcohol metabolism — how quickly your body processes alcohol — varies widely from person to person. Hepatologist Jamile Wakim-Fleming, MD , explains how your body gets rid of alcohol and what affects this process. The liver gets most of the attention when it comes to alcohol metabolism.
These enzymes help divert some of the alcohol from going into your bloodstream. From there, it hits your bloodstream and your brain, and you start feeling its effects. The liver does the heavy lifting when it comes to processing alcohol. After the alcohol passes through your stomach, small intestine and bloodstream, your liver starts its cleanup.
The rest comes out through your kidneys, lungs and skin. And the concentration matters. Two ounces of spirits contain much more alcohol than two ounces of wine. After you start drinking, alcohol takes around 60 to 90 minutes to reach peak levels in the blood. Then, the body begins breaking it down.

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. The metabolism of alcohol has been studied in detail, but there are many individual factors that determine how long it can be detected in your body and how long it will take to be eliminated.
Depending on the type of test used as well as your age, body mass, genetics, sex, and overall health, alcohol can remain detectable in your system from 10 hours to 90 days. When misused, alcohol can do as much or even more overall harm as many illegal drugs. People who misuse alcohol also risk developing physical and psychological dependence and alcohol use disorder.
You can start to feel the effects of alcohol in a matter of minutes. When ingested, alcohol is rapidly absorbed from the stomach and small intestine into your bloodstream before it travels to the nervous system brain and spinal cord. As a central nervous system depressant, alcohol impairs the communication of messages in your brain, altering your perceptions, emotions, movement, and senses.
For some, this can mean being more talkative or very friendly and others may begin to behave with anger or aggression. Other signs of alcohol intoxication include:. The half-life of ethanol is about 4 to 5 hours, which means it takes that long to eliminate half of the alcohol ingested from the bloodstream. For most people, alcohol is absorbed into the system more rapidly than it is metabolized.
For a person weighing pounds, for example, one standard drink will increase their blood-alcohol concentration by about 0. If you drink more than one per hour, it rises much more rapidly. The body metabolizes alcohol by oxidizing the ethanol to acetaldehyde. The acetaldehyde is broken down into acetic acid and then to carbon dioxide and water. 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. The following is an estimated range of times, or detection windows, during which alcohol can be detected by various testing methods.
Alcohol can be detected in your breath via a breathalyzer test for up to 24 hours. Alcohol can be detected in urine for three to five days via ethyl glucuronide EtG metabolite or 10 to 12 hours via the traditional method.
Alcohol can show up in a blood test for up to 12 hours. A saliva test can be positive for alcohol from 24 to 48 hours. Like many other drugs , alcohol can be detected with a hair follicle drug test for up to 90 days.
The EtG test can produce a positive test from the mere exposure to alcohol that's present in many daily household products such as cooking extract, mouth wash, cleaning products, cosmetics, and hair dye. As such, it's a less reliable test for alcohol consumption. If you take a breath or saliva test shortly after using alcohol-containing mouthwash or cough medicine, it may detect the residue of the alcohol in your mouth and create a false positive as well.
