No detectable BACs were observed in the placebo group (i.e., 0.00‰). In the alcohol group, the mean BAC level 25 min after initiation of drinking alcohol (BAC2) was 0.72‰ (SD = 0.18; range = 0.39–1.12‰). Mean BAC level before the start of the BART (BAC3; approximately 50 min after initiation of drinking) was 0.77‰ (SD = 0.13; range = 0.52–0.97‰) and mean BAC level a further 15 min later (BAC4), after completion of the BART, was 0.72‰ (SD = 0.11; range = 0.48–0.93‰). As expected, the peak BAC occurred about 60 min after drinking (see Fig. 1).
