How Long Does Alcohol Stay in the Body?ĭepending on how much you’ve consumed, the type of test used and some biological factors about the person drinking the alcohol, the amount of time the substance can be detected in your system can vary widely. Read on to find out more about how long alcohol stays in your system, including parts of the body like blood, urine, saliva and hair. On average, a person will metabolise the equivalent of one alcoholic drink per hour, but this can vary based on your weight, height, gender and body composition. When you consume alcohol, the metabolising process is done primarily by your liver. This process happens when you consume any food or drink. Metabolism is the body’s chemical process for breaking down a substance to be absorbed or used as energy. When alcohol enters your system, your body will begin to metabolise it.
