• Moderate alcohol consumption: According to the Dietary Guidelines for Americans, moderate drinking is up to 1 drink per day for women and up to 2 drinks per day for men.
  • Binge drinking: Binge drinking is 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. Binge drinking has become a major health and safety issue on college campuses.
  • Heavy drinking: Heavy drinking is defined as drinking 5 or more drinks on the same occasion on each of 5 or more days in the past 30 days.
  • Low risk for developing an alcohol use disorder: For women, low-risk drinking is no more than 3 drinks on any single day and no more than 7 drinks per week. For men, it’s defined as no more than 4 drinks on any single day and no more than 14 drinks per week. NIAAA research shows that only about 2 in 100 people who drink within these limits have an alcohol use disorder.  Even within these limits, you can have problems if you drink too quickly or have other health issues.
