Alcohol's presence in your body depends on several factors, including the amount consumed, your body weight, and your metabolic rate. Typically, alcohol can be detected in your bloodstream for up to 12 hours after consumption. However, its effects can last longer, with trace amounts remaining detectable for up to 24 hours in urine and even longer in hair follicles. Understanding how long alcohol stays in your system is crucial for anyone looking to monitor their intake or prepare for tests.
