Given that previous studies have shown that the subjective effects of alcohol are alcohol dose-dependent (Anton et al., 2004; Drobes et al., 2004; McCaul et al., 2001; Ray & Hutchison, 2007), BAC was estimated in this study on the basis of alcoholic beverage type and amount, gender, weight, and time elapsed from alcohol consumption. Participants were asked if they drank beer, wine, wine cooler, fortified wine, mixed drink, or straight liquor, and reported the number of ounces consumed (Possible range 0–40 ounces). On the basis of beverage type and quantity, those drinks were converted into standard drinks using the standard drink definition provided by NIAAA (2005), such that a standard drink (containing 14 grams of alcohol) was defined as: 12 oz. of beer, 5 oz. of wine, 12 oz. of wine cooler, 3.5 oz. of fortified wine, and 1.5 oz. of hard liquor (in a mixed drink or as straight liquor).
