B4Udrink is an interactive tool that allows users to calculate their estimated blood alcohol concentration (BAC) based on the following:

  • gender
  • weight
  • type and number of drinks
  • how fast the drinks are consumed

It also provides information about the effects of alcohol at various BAC levels, the impact of food, and how alcohol affects everyone differently.

B4Udrink is available online in English and Spanish at www.B4Udrink.org.
