Consumption of a large dose of alcohol in a short time span.

Blood alcohol concentrations (BAC) and time to peak BAC were determined in 16 subjects after ingestion of a large quantity of alcoholic beverages within a short drinking time span not exceeding 30 min. The first group (7 subjects) consumed alcohol after a 3- to 4-h fast. In the second group (9 subjects) the consumption of alcohol took place after eating a large meal. Venous blood samples taken 30 min after drinking finished were compared to the near-simultaneous Breathalyzer results. In addition, the minimum duration of a BAC plateau for these drinking circumstances was assessed.
