NIAAA defines binge drinking as a pattern of drinking alcohol that brings blood alcohol concentration (BAC) to 0.08 percent – or 0.08 grams of alcohol per deciliter – or higher. For a typical adult, this pattern corresponds to consuming 5 or more drinks (male), or 4 or more drinks (female), in about 2 hours.
SAMHSA defines heavy alcohol use as binge drinking on 5 or more days in the past month.
Knowing U.S. standard drink (or alcoholic drink-equivalent) sizes and the number of drinks per container can help you make informed decisions about your drinking.
You’ll be able to:
- Count drinks more accurately
