How long does it take for the body to rid itself of 1 oz of liquor after consumption?

The body metabolizes alcohol at an average rate of about 0.015% blood alcohol concentration (BAC) per hour. For a rough estimate, this translates to approximately one standard drink, which is defined as containing about 0.6 ounces of pure alcohol, being processed in about one hour.

Since 1 ounce of liquor contains more than one standard drink, it typically takes longer than that one hour. In general, it is widely accepted that the body can process 1 ounce of liquor in about 2 to 3 hours. Specifically, option B, which suggests 3 hours, aligns with the understanding of alcohol metabolism and reflects the time required for the body to adequately eliminate the alcohol ingested.

Understanding this concept is crucial, particularly in circumstances involving flight safety, where a pilot needs to be mindful of the time and effects of alcohol consumption on their ability to operate an aircraft effectively.
