A description of 1074 high school students' alcohol and other drug (AOD) use along with the consequences of such use was supplemented with comparisons of grade level and gender differences and analyses of the relationships between AOD use and incidence of adverse consequences with grade point average, attendance at religious services, frequency of dating, frequency of driving a car and frequency of having trouble at school. Alcohol was clearly the drug of choice and produced a variety of adverse consequences. Most frequently reported were arguments, trouble with parents and at school and nausea or vomiting. Grade level differences were found, but few significant gender differences emerged. Significant relationships between AOD use and consequences with all other independent variables were found.
