The country’s highest percentage of heavy drinkers can be found in Washington DC, according to a new study.

More than half of the adults in DC have had at least one drink in the past month, the study shows, and 11.1 percent of residents consumed more than one a day.

Researchers from Detox.net collected their data by conducting phone interviews with people across the country and examining info from the Center for Disease Control and Prevention’s Behavioral Risk Factor Surveillance System.

The study labeled men who consume more than two alcoholic beverages a day and women who knock back more than one “heavy drinkers” — and men who have had five or more drinks and women who have four or more “binge drinkers.”

Washington has the highest percentage of both.

“That may be a concerning metric for a city that recently relaxed its restrictions on the sale of alcohol,” researchers wrote in their findings, noting a law change from earlier this year that expanded the District’s licensing standards.

Instead of selling beer in just growlers or jugs, local breweries are now allowed to hawk their product in cans, kegs and bottles. Grocery stores that were once banned from selling wine, cider and mead can now do so freely, so long as its in a growler.

According to Detox, roughly one in eight Americans suffer from alcohol addiction — with women and minorities struggling with the problem more than anyone else.
