Many laboratory participants reached the safety limit of 150 mg/dl. DI group significantly predicted the time until a participant reached binge drinking BrAC threshold (80 mg/dl; overall p = 0.004, AIC = 153.7) with five participants not reaching 80 mg/dl (Figures 2 and 3). The extreme‐risk DI group reached a BrAC of 80 mg/faster (mean 33.3 min) than the high‐risk DI group (mean 57.2 min); hazard ratio = 3.33, 95% CI = [1.22, 9.09], p = 0.02, and faster than the moderate‐risk DI group (mean 85.4 min); hazard ratio = 7.14, 95% CI = [2.22, 21.74], p = 0.01; There was an emerging trend in the difference in time between the high‐ and moderate‐risk DI groups; hazard ratio = 2.13, 95% CI = [0.85, 5.26], p = 0.10. FHD, nicotine, and gender were not associated with time until binge level exposure occurred for the DI groups (all ps > 0.10).
