"Most Heavy Drinkers Are Not Alcoholics."-New York Times.

"Drinking heavily is defined as having eight or more alcoholic drinks in a week for women, and 15 or more drinks per week for men. Binge drinking, on the other hand, is defined by the U.S. Centers for Disease Control and Prevention (CDC) as consuming four drinks for women and five drinks for men in a single occasion.  To be considered an alcoholic, one should be unable to stop or reduce drinking, having the need to continue drinking even if it causes problems with family or work, and excessive time spent drinking on a daily basis."
