Definitions of Heavy and Binge Drinking According To SAMHSA
"In addition to asking about any alcohol use, NSDUH collected information on past month binge alcohol use and heavy alcohol use. Binge drinking for males was defined as drinking five or more drinks18 on the same occasion on at least 1 day in the past 30 days, which has remained 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.19 This definition of binge alcohol use is consistent with federal definitions.20 Heavy alcohol use was defined as binge drinking on 5 or more days in the past 30 days based on the thresholds described previously for males and females.
"Among the 139.7 million current alcohol users aged 12 or older in 2019, 65.8 million people (47.1 percent) were past month binge drinkers (Figure 6). Among past month binge drinkers, 16.0 million people (24.4 percent of current binge drinkers and 11.5 percent of current alcohol users) were past month heavy drinkers.21"
