Alcohol Detection Window: How Long Does Alcohol Stay in Blood?

Elimination varies by age, weight, sex, intake, health. Estimates:

  • 1‑2 drinks: ~1‑2 hours per standard drink.
  • 3‑5 drinks: ~3‑5 hours.
  • Binge (5+ drinks): 10‑12+ hours.

Individual metabolism, medications, and conditions alter these times. Discuss concerns with a clinician; practice responsible drinking.
