An alcohol-induced blackout is a memory-encoding failure of the hippocampus that occurs typically above 0.16% BAC. The drinker may walk, talk, and even drive home with no memory the next day. Blackout drinkers are extremely high risk: still legally drunk, often disinhibited, and prone to victimization or violence. Loss of consciousness (passing out) is a separate, even more severe stage. A patron showing blackout behavior (repeating themselves, not recognizing companions) requires immediate cut-off and safe transport.
