A new report by the Centers for Disease Control and Prevention highlights the dangers of binge drinking.
College-age drinkers average about nine alcoholic drinks a night when they binge, according to the report.
Nearly one in six adults in this country over indulge at least once a month.
However, alcohol sales figures tell another story. They suggest people are buying a lot more alcohol than they say they're consuming.
Health officials estimate that about half of the beer, wine, and liquor consumed in the United States by adults each year is consumed during binge drinking.
"I know this sounds astounding, but I think the numbers we're reporting are really an underestimate," Dr. Robert Brewer, who leads the alcohol program at the Centers for Disease Control and Prevention, told the Associated Press.
Men are most likely to binge drink. So are people who've been to college and those with incomes of $75,000 or more.
Health officials say binge drinking accounts for more than 40,000 deaths a year in the U.S.
