How Long Does Alcohol Stay In Your System? Blood & Urine

How well the liver can process alcohol will determine on the individual’s BAC. For the most part, certain biological differences and lifestyle habits have been shown to affect how alcohol interacts with the liver and bloodstream. A blood alcohol level of 0.45% is lethal for approximately 50% of the population. At around 0.15% BAC, most people begin vomiting due to excess alcohol in the blood and the body’s inability to metabolize the alcohol fast enough.

That’s because blood alcohol concentrations can vary among people and situations. Blood alcohol concentration refers to the amount of alcohol in your blood in relation to the amount of water in your blood.

How long alcohol stays in your system depends on a number of external and internal factors, some of which are unique to every person. Characteristics like age, weight, sex, and medical history all play a part in how concentrated the alcohol in your blood is after drinking also known as blood alcohol concentration or BAC. However, virtually all humans metabolize alcohol at a constant rate of 20 milligrams per deciliter (mg/dL) per hour, or 0.015 BAC every hour. This means that a blood alcohol level of 80 mg/dL will take four hours to metabolize and a BAC of 0.08 will take approximately 5.33 hours before there is no measurable alcohol in the blood.

This is especially true if the urine sample is left out at room temperature, where the microorganisms can continue to ferment glucose and create more alcohol. It depends on how much alcohol you’ve had to drink and whether it’s your urine, hair, blood, saliva, or breast milk being tested.

Many people mistakenly believe that having no measurable BAC means they have no alcohol in their system. On the contrary, BAC is merely a measure of alcohol’s concentration in the blood which is filtered rapidly and on a continuous, unending basis. Subsequently, alcohol can only be detected in the blood for several hours after the last drink. Other measuring tools for BAC, including breathalyzers, urine samples, and sweat tests, only estimate the amount of alcohol present in blood. The length of time alcohol stays in the system is different for everyone.

The 80% of alcohol that doesn’t enter the bloodstream through the stomach does so through the small intestine. Detox should be handled by professionals as the first step of residential treatment.

The longer alcohol stays in the stomach, the longer it takes to be absorbed and the slower the rate of intoxication. Eating before drinking, and continuing to snack while you consume alcohol, will slow the absorption and reduce its impact, but prolong the detection period. 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.
