After 5 hours â your BAC would be 0.005. Alcohol would be eliminated from the body at about 5 hours and 20 minutes (the body metabolizes alcohol at the rate of about 0.005 per twenty minutes, as 0.005 x 3 = 0.015). So it is easy to tell when your body will be free of alcohol.
Beer and wine are not âsaferâ than hard liquor. A 12-ounce can of beer, a 5-ounce glass of wine, and 1.5 ounces of hard liquor all contain the same amount of alcohol and have the same effects on the body and mind.

People tend to be very bad at judging how seriously alcohol has affected them.
