Abstract (Summary)

The purpose of this study was to analyze factors that predict marijuana use and grade point average among undergraduate college students using the Core Institute national database. The Core Alcohol and Drug Survey was used to collect data on students’ attitudes, beliefs, and experiences related to substance use in college. The sample used in this study was delimited to include only full-time undergraduate students (N =111,664) and data were collected from 2011 to 2015. Six research questions provided the foundation of the study, which was operationalized by Astin’s (1993) input environment outcome model (IEO).

Descriptive analysis was conducted to describe the sample in terms of individual and institutional characteristics, campus experiences, and substance use. Comparative analyses including one-way analysis of variance and two-way analysis of variance were conducted to determine statistical significance of differences between groups for gender, ethnic origin, marijuana use, and grade point average. Effect sizes were calculated for each ANOVA to determine the magnitude of the effect and practical significance for the population. Finally, inferential analyses using hierarchical, multiple regression were conducted to predict marijuana use. The regression model was also used to explore factors predicting medical marijuana and recreational marijuana use among students in the 2015 cohort. Statistically significant results were reported for each regression model. Statistically significant at p < .001, the factors that explained 42.2% of the variance in the final model included: gender, ethnic origin, age, institutional control, campus locale, intercollegiate athletics, social fraternities and sororities, music and performing arts, alcohol use, illegal drug use change, perceived risk of harm from trying marijuana once or twice, and perceived risk of harm from smoking marijuana regularly. Implications for policy, practice, and future research regarding marijuana use and academic performance are included.
