How long does alcohol stay in your system? Mostly broken down in the live, when alcohol enter’s someone’s system the body begins to metabolize it. However, the time it takes for your body to metabolize alcohol depends on numerous factors including age, gender, the food in your body, among other factors. This article will explain in depth, how long alcohol stays in the body, how long it remains detectable, and other variables including when alcohol abuse turns into alcoholism.
How Long Does Alcohol Stay in Your System?
Blood: On average, alcohol stays in the blood for 1 to 3 hours, but this can vary based on several factors. Blood tests can typically detect alcohol for up to 24 hours after consumption.
Urine: Alcohol can be detected in urine for up to 48 hours after consumption using traditional methods. However, with more advanced tests, alcohol metabolites (like ethyl glucuronide) can be detected for up to 3 to 5 days post-consumption.
Hair: Hair tests provide a much wider window of detection. Alcohol and its metabolites can be identified in hair follicles for up to 90 days after consumption.
Saliva: Alcohol remains detectable in saliva for about 24 to 48 hours.
Breath: Breath tests, commonly known as breathalyzers, can detect alcohol usually within 12 to 24 hours after drinking.
How Long Does It Take For Alcohol to Kick In?
Most people begin to feel the effects of alcohol within about 10 to 30 minutes of consumption. On an empty stomach, alcohol is absorbed more quickly, often leading to a quicker onset of effects. Peak blood alcohol concentration (BAC) is typically reached within 30 minutes to 2 hours post-consumption.
How Is Alcohol Metabolized?
Alcohol metabolism is primarily a two-step process that occurs mainly in the liver, though some can also occur in the stomach and other tissues. Here is how the body typically breaks down alcohol:
Step 1: Alcohol Dehydrogenase (ADH) Pathway
When alcohol is consumed, it first enters the digestive system. A small amount is metabolized by enzymes in the stomach, but the majority passes through to the small intestine and is absorbed into the bloodstream.
The liver metabolizes the bulk of the alcohol using the enzyme alcohol dehydrogenase (ADH). ADH converts ethanol into a toxic compound called acetaldehyde. This enzyme is found in many tissues of the body, including the stomach lining, but the liver is where alcohol is primarily metabolized.
Step 2: Aldehyde Dehydrogenase (ALDH) Pathway
Acetaldehyde is highly toxic and potentially carcinogenic. Consequently, it is rapidly broken down by another enzyme called aldehyde dehydrogenase (ALDH). ALDH converts acetaldehyde into acetate, which is further broken down into water and carbon dioxide for easy elimination from the body.
While the ADH pathway is the primary route for alcohol metabolism, the body also employs other mechanisms, particularly when the levels of alcohol consumption are high:
- Microsomal Ethanol Oxidizing System (MEOS): When the ADH system becomes saturated due to high levels of alcohol, the MEOS kicks in. It involves the cytochrome P450 enzyme system, particularly CYP2E1, to oxidize ethanol to acetaldehyde. This system is not as efficient as ADH and generates reactive oxygen species, potentially contributing to liver damage (a condition known as alcoholic liver disease).
- Catalase Pathway: This is a minor pathway where catalase, an enzyme in liver cells, uses hydrogen peroxide to oxidize ethanol into acetaldehyde. It is considered a minor pathway because it accounts for a small fraction of alcohol metabolism.
Rate of Metabolism
The average rate at which the body can process alcohol is about one standard drink per hour, but this can vary widely between individuals due to factors like genetics, age, sex, the presence of food in the stomach, and the function of their ADH and ALDH enzymes. Some individuals, particularly those of East Asian descent, have a variant of the ALDH enzyme that works less effectively, leading to a buildup of acetaldehyde and the subsequent facial flushing, nausea, and rapid heartbeat often referred to as the “Asian flush.”
Women generally have less ADH activity in the stomach compared to men, which means that a higher percentage of alcohol reaches the bloodstream and liver to be metabolized. This is one reason why women may feel the effects of alcohol more quickly and intensely than men of the same size and weight.

How Is Alcohol Measured in the Body?
The amount of alcohol in a person’s system is usually measured as Blood Alcohol Concentration (BAC). It represents the percentage of alcohol in a person’s blood. For instance, a BAC of 0.08% means that there are 0.08 grams of alcohol for every 100 milliliters of blood.
Factors That Affect How Alcohol Is Processed
- Body Weight and Composition: Individuals with higher body weight or fat content may process alcohol differently than those with lower body weights.
- Gender: Women often metabolize alcohol differently than men, leading to higher BAC levels with the same amount of alcohol consumption.
- Age: Metabolism rates tend to decrease with age, which can lead to prolonged alcohol processing times.
- Food Intake: Consuming alcohol on an empty stomach can lead to rapid absorption and a quicker peak BAC.
- Medications: Some medications can interfere with alcohol metabolism, either speeding up or slowing down the process.
- Tolerance: Individuals with a higher tolerance may not feel the effects of alcohol as acutely, but this doesn’t change the rate at which alcohol is metabolized.
What is a Standard Drink?
In the U.S., a standard drink contains about 14 grams (0.6 ounces) of pure alcohol. This is roughly:
- 12 ounces of beer (with about 5% alcohol content)
- 5 ounces of wine (with about 12% alcohol content)
- 1.5 ounces of distilled spirits (with about 40% alcohol content)
It’s important to note that these are just approximations, and actual alcohol content can vary.
When Does Alcohol Abuse Turn into Alcoholism?
Alcohol use turns into alcoholism or alcohol use disorder (AUD) when one can’t control their drinking, becomes preoccupied with alcohol, continues to use alcohol even when it causes problems, or has developed a tolerance or withdrawal symptoms. Some signs of AUD include:
- Drinking more or longer than intended
- Inability to cut down or control alcohol use
- Spending a lot of time obtaining, using, or recovering from alcohol
- Craving or a strong desire to use alcohol
- Failing to fulfill major obligations at work, school, or home due to alcohol use
How Is Alcohol Use Disorder Treated?
The treatment for AUD can take several forms, ranging from detox to inpatient rehab and various outpatient programs to virtual interventions. Here are some of the common treatment modalities:
A Partial Hospitalization Program (PHP) is a structured program providing intensive treatment while allowing patients to live at home. It can serve as a step-down from inpatient treatment or as an alternative when full hospitalization isn’t necessary. PHP typically involves attending treatment sessions at a hospital or treatment center for multiple hours each day, several days a week. It provides a high level of care, including medical monitoring, while offering more freedom than inpatient rehab.
Intensive Outpatient Programs are treatment programs used to address addictions, depression, eating disorders, or other dependencies that do not require detoxification or round-the-clock supervision. IOP allows the patient to continue with their daily life in a way that residential treatment programs do not. Typically, patients attend sessions multiple times a week, which may include individual counseling, group therapy, educational sessions, and skill-building activities.
With the advancement of telehealth services, Virtual IOP has become a viable option for many patients. This form of treatment involves participating in intensive outpatient programs through online platforms. It allows for flexibility and accessibility, especially for individuals living in remote areas, those with transportation challenges, or individuals who prefer receiving treatment in the privacy of their own home. Virtual IOP can provide therapy sessions, peer support meetings, and psychiatric services via video conferencing.
Long-term rehab programs provide extended care for people with severe AUD. These programs can last from a few months to a year or more. They offer a stable environment free from alcohol, a structured schedule of therapy, social support from peers, educational workshops, and sometimes vocational training. The extended nature of these programs allows individuals to deeply engage in their recovery journey and build a strong foundation for a life without alcohol.
Outpatient rehab programs are less intensive than PHP or IOP. Patients attend therapy and counseling sessions for a few hours per week while maintaining their regular activities like work or school. This type of rehab often includes group counseling, one-on-one therapy, and may also involve family therapy. It is best suited for individuals with a strong support system at home and those with less severe forms of AUD.
