The B4UDrink Educator, which allows users to learn how alcohol consumption affects individuals' Blood Alcohol Concentration (BAC) level, has now expanded. In addition to B4Udrink.org's online Virtual Bar, users can now use the interactive program on the go by navigating to B4UDrink.mobi on cell phones, BlackBerrys, PDAs, iPhones, and any other smart phones and devices with internet access. Now that B4UDrink has gone mobile, you can estimate BAC levels before you drink anywhere and everywhere you take your mobile phone!
