Alcohol is a substance found in drinks like beer, wine, and liquor that affects the brain and body when consumed.The amount of time alcohol stays in the body is different for everyone. It depends on factors like how much alcohol was consumed, how quickly it was consumed, body weight, metabolism, age, and overall health. While the body generally processes about one standard drink per hour, alcohol does not leave the system immediately. Traces of alcohol can still be found in the blood, breath, urine, or hair hours or even days after drinking. Understanding this can help people make safer decisions related to driving, work, and personal health.
