How Long Does Alcohol Stay in Your System?
Some may ask, how long does alcohol stay in your system? Read on to learn how long you may feel the effects of alcohol.
How the Body Processes Alcohol
Alcohol is metabolized through the digestive system. However, alcohol isn’t a core nutrient, so it does not get digested in the same way as food.
Alcohol addiction is a serious problem in the United States. Unfortunately, people can accidentally ingest more alcohol than they can handle and become drunk or addicted to alcohol if they don’t know how long alcohol remains in their systems. Understanding how long alcohol stays in your system is vital to drinking responsibly and minimizing moments of impaired judgment.1

Alcohol in the Body
Alcohol enters the body's upper gastrointestinal tract and is then absorbed directly into the bloodstream via the tissue lining of the intestines and the stomach. Alcohol is metabolized more quickly when you have an empty stomach vs. if you have eaten recently. Food inhibits the body’s ability to absorb alcohol or contact the stomach lining.
Regardless, a healthy individual usually experiences the effects of alcohol within 15 to 45 minutes of ingesting it.
Blood Alcohol Concentration
The total amount of alcohol in an individual's bloodstream is called the Blood Alcohol Concentration or BAC. This is expressed as a percentage of alcohol/ethanol in blood based on units of mass of alcohol per volume.2
For example, one ounce of alcohol induces a BAC of 0.15% in most individuals. The negative effects of alcohol begin to increase if an individual’s BAC goes above 0.05%. At 0.08% to 0.09%, many of the symptoms of alcohol impairment begin to show at this point, such as slurred speech or difficulty maintaining balance. Remember, driving a motor vehicle with a BAC of 0.08% or more is illegal in the US.
How Do You Know When You’re Drunk?
There are many symptoms associated with alcohol absorption. People can tell when they are drunk if they experience symptoms such as:
Depending on the individual, drunkenness may bring on one or many of the above symptoms. Everyone reacts differently to alcohol.
Factors that Influence Alcohol Processing
Many different biological factors influence how quickly the body absorbs and processes alcohol. Because of this, certain people can “safely” consume alcohol more than others. Some of the most common factors that influence alcohol processing include:
Certain medications may alter the body’s metabolism and impact alcohol processing. This can slow down how quickly the body absorbs alcohol or result in the reverse effect. Medications that interact with alcohol include but are not limited to cold and/or cough medicines, ADHD medications such as Adderall, and antianxiety medications like Xanax.
The larger a person is, the more alcohol they must consume to feel negative effects (since they have more blood and mass per unit). However, individuals with more body fat usually have a higher BAC since fatty tissue does not absorb alcohol like muscle tissue. The reverse is true for very muscular individuals.
Those who consume food before consuming alcohol may absorb it more quickly.
Men and women metabolize alcohol differently. In general, alcohol stays in a woman’s system for longer, so they are more at risk of suffering the negative effects of alcohol consumption than men (assuming two equally sized individuals consume the same amount of alcohol).
The older one is, the longer alcohol remains in their liver before going into the bloodstream or being metabolized.
Risks of Alcohol Abuse
Those diagnosed with schizophrenia may find their symptoms exacerbated by excessive alcohol consumption. The same is true for individuals who have received a diagnosis of major depressive disorder.
Furthermore, alcohol abuse makes personality disorders more likely to appear, particularly in at-risk individuals. Drinking at an early age or drinking with a family history of alcohol use disorder may increase one's likelihood of developing alcohol dependence or addiction. This is also true for those with a history of trauma; alcohol can numb emotional pain and lead to dependence or addiction.
False Positives in Alcohol Testing
While alcohol testing is important for workplaces and law enforcement, some tests can return false positives for certain absorbed products. These products include breath sprays, mouthwashes, hair dyes, aftershave, antiperspirants, and alcohol-based hand sanitizers. If you know you are due to take an alcohol test soon, avoid these products, so you aren't penalized for a false negative.4
