Alcohol & BAC: Understanding Blood Alcohol Content in 18-Year-Old Females

The number of drinks to reach a given BAC varies by weight, height, metabolism, and tolerance. As a rough guide, an average 18-year-old female may reach 0.08% BAC (legal driving limit in many places) after 4–5 standard drinks. Even 0.02% impairs judgment and coordination.

Responsible Drinking Tips

• Set and stick to a personal limit.
• Pace drinks; sip slowly.
• Avoid mixing alcohol with energy drinks/caffeine.
• Alternate with water.
• Eat before drinking.
• Stop if you feel drunk; rest.
• Never drink and drive.
