"More than 38 million U.S. adults binge drink an average of four times each month, according to a new report from the U.S. Centers for Disease Control and Prevention. The agency notes that the majority of people who binge drink are not alcoholics, but the trend is alarming because of the number of serious problems that can occur when people have too much alcohol, such as car accidents, violence and sexually transmitted diseases."

The CDC reports that too much drinking results in 80,000 deaths each year in the U.S., and cost the country more than $223.5 billion in 2006.

The agency defines binge drinking as women having four or more drinks in a sitting and men drinking five or more, but the definition of binge drinking can vary. According to the National Institute on Alcohol Abuse and Alcoholism, the same amount of alcohol must be consumed in two hours or less to qualify as binge drinking, an amount that would put a person's blood alcohol level above the legal driving limit, Crews said.

According to the CDC's report, binge drinking is more common among young adults ages 18 to 34 and among wealthier Americans, those with an annual household income of $75,000 or more. But binge drinkers age 65 and older reported drinking more in one sitting, and people with an annual income of less than $25,000 per household drank the largest number of drinks per sitting - about eight or nine at a time.
