According to the "Dietary Guidelines for Americans 2020-2025,” U.S. Department of Health and Human Services and U.S. Department of Agriculture, adults of legal drinking age can choose not to drink or to drink in moderation by limiting intake to 2 drinks or less in a day for men and 1 drink or less in a day for women, when alcohol is consumed. Drinking less is better for health than drinking more.

  • 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.
  • 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.

    • For men, consuming fiveor more drinks on any day or 15or more per week
    • For women, consuming fouror more on any day or 8 or moredrinks per week
  • SAMHSA defines heavy alcohol use as binge drinking on 5 or more days in the past month.

  • Plan to drive or operate machinery, or participate in activities that require skill, coordination, and alertness
