Cues to start and end drinking episodes as a function of family drinking history

College students with positive (FH+) and negative (FH-) family history for heavy frequent alcohol use showed no differences in age of first drink, amount consumed then, amount currently consumed, current frequency, maximum consumed, or effect of current alcohol consumed. However, there were FH background differences in the reasons identified for ending, but not for starting, drinking episodes involving intoxication. The realization of already drinking too much ended these drinking episodes more often among FH- than for FH+ subjects. In contrast, nausea and lateness of the hour were related to the end of drinking more often for FH+ subjects.
