"Consistent with federal definitions²¹ and other federal data collections, the NSDUH definition for binge alcohol use since 2015 differs for males and females. Binge drinking for males is defined as drinking five or more drinks²² on the same occasion on at least 1 day in the past 30 days, which is unchanged from the threshold prior to 2015. Since 2015, binge alcohol use for females has been defined as drinking four or more drinks on the same occasion on at least 1 day in the past 30 days.
