The question of how long it takes for alcohol to be excreted in the body cannot be generalized and varies according to the amount of alcohol consumed, the concentration of alcohol consumed, the type of alcohol consumed and the individual differences of the human body. Usually, alcohol is absorbed within 30 minutes, and the peak concentration of absorption is reached within 2 hours, which is the maximum amount of absorption, but the metabolic situation usually varies from person to person. It usually takes 24-48 hours to be completely eliminated. For people with a relatively good metabolism ability and a relatively good basic constitution, the metabolism of alcohol in the body is usually faster and can be finished within 24 hours.
