Field assessment of BAC data to study late-night college drinking.

Abstract

Field assessment of student intoxication is an important tool for examining research questions in college drinking. The 5+/4+ measure classifies many college students as heavy episodic drinkers, even though their intoxication level is below conventional thresholds used to define drunkenness. In addition, there is a discernible pattern of BAC estimation in the field that corresponds to intoxication level.
