Answer: The rate at which alcohol leaves your bloodstream can vary depending on several factors, including your body weight, metabolism, and the type and amount of alcohol consumed.
In general, the liver can metabolize approximately one standard drink per hour. A standard drink is typically defined as containing about 14 grams (or 0.6 ounces) of pure alcohol. you mentioned having three beers, it's important to note that the alcohol content of each beer can vary. On average, a regular beer contains around 14 grams of pure alcohol. we can estimate that it may take about three hours for the alcohol from those three beers to fully leave your bloodstream. However, keep in mind that individual factors can influence this estimation, and it's always best to allow sufficient time for your body to process and eliminate alcohol before engaging in activities that require full sobriety. It's also worth noting that consuming large amounts of alcohol can have lingering effects on your cognition and coordination even after the alcohol has left your bloodstream.
