Drinking Levels Defined
Moderate alcohol consumption:
According to the "Dietary Guidelines for Americans 2015-2020,” U.S. Department of Health and Human Services and U.S. Department of Agriculture, moderate drinking is up to 1 drink per day for women and up to 2 drinks per day for men.
NIAAA defines binge drinking as a pattern of drinking that brings blood alcohol concentration (BAC) levels to 0.08 g/dL. This typically occurs after 4 drinks for women and 5 drinks for men—in about 2 hours.
- The Substance Abuse and Mental Health Services Administration (SAMHSA), which conducts the annual National Survey on Drug Use and Health (NSDUH), defines binge drinking as 5 or more alcoholic drinks for males or 4 or more alcoholic drinks for females on the same occasion (i.e., at the same time or within a couple of hours of each other) on at least 1 day in the past month.
Certain people should avoid alcohol completely, including those who:
Plan to drive a vehicle or operate machinery
Take medications that interact with alcohol
Have a medical condition that alcohol can aggravate
Are pregnant or trying to become pregnant
