ABSTRACT Use of marijuana and alcohol among current college students (N = 1101) was compared to the perceptions and use of entering freshmen (N = 481) surveyed before the start of classes. Entering freshmen significantly misperceived campus norms for marijuana use, over-estimating that almost every student used in the last 30 days, p <.001. Perceptions of alcohol use were relatively accurate. These discrepancies in perception could account for why 40.5% of entering students perceived the campus atmosphere to be promoting marijuana use, whereas only 16.2% perceived the campus atmosphere to be promoting alcohol use. How these misperceptions of social norms might be influenced by the reputation of the campus-and how this might affect potential applicants and enrolled students' behaviors are discussed.

    ABSTRACT: Background & Aims: This study investigated high-risk drinking and polydrug use (PU) over 6 months for freshmen college students. Methods: The Brief Alcohol Screening and Intervention for College Students (BASICS) brief motivational interviewing (BMI) intervention was implemented at a public university as a 3-year programme designed to reduce underage drinking among freshmen with a secondary focus on PU. Participants were 299 freshmen from a state-supported university. Participants attended baseline visit, 2-week, 3- and 6-month visits. Analysis: Paired t-tests were used to determine the differences between alcohol consumption at different time points. McNemar’s test was used to compare correlated proportions. Results: At the baseline, 30% of the participants were drinking and using illicit drugs, compared with 25% at the sixth month visit. Conclusion: The findings suggest that a decrease in alcohol consumption will also reduce the probability of PU. These findings can assist in developing health professional strategies for effective use of BMI interventions aimed at alcohol and PU.

    ABSTRACT: This study examined descriptive and injunctive normative influences exerted by parents and peers on college student marijuana approval and use. It further evaluated the extent to which parental monitoring moderated the relationship between marijuana norms and student marijuana outcomes. A sample of 414 parent-child dyads from a midsize American university completed online surveys. A series of paired and one-sample t tests revealed that students' actual marijuana use was significantly greater than parents' perception of their child's use, while students' perception of their parents' approval were fairly accurate. The results of a hierarchical multiple regression indicated that perceived injunctive parent and student norms, and parental monitoring all uniquely contributed to the prediction of student marijuana approval. Furthermore, parental monitoring moderated the effects of perceived norms. For example, at low but not high levels of parental monitoring, perceptions of other students' marijuana use were associated with students' own marijuana approval. Results from a zero-inflated negative binomial regression showed that students who reported higher descriptive peer norms, higher injunctive parental norms, and reported lower parental monitoring were likely to report more frequent marijuana use. A significant Parental Monitoring × Injunctive Parental norms interaction effect indicated that parental approval only influenced marijuana use for students who reported that their parents monitored their behavior closely. These findings have intervention implications for future work aimed at reducing marijuana approval and use among American college students.

    ABSTRACT: Tobacco and marijuana are commonly used by college students and have negative health effects. The purpose of the study was to understand how students' attitudes, intentions, and behaviors toward tobacco and marijuana change during freshman year and to examine how attitude and intention predict use of these substances. College students completed phone interviews before and after freshman year. The identical interviews assessed students' attitudes, intentions, and behaviors toward both substances. Attitude was measured on a 0-6 scale (6 = most positive), intention on a 0-5 scale (5 = very likely to use), and behavior by lifetime use (yes or no) and current use (past-28-days). Overall, 275 participants completed both interviews. Attitudes increased (tobacco 0.9 to 1.2, p < 0.01; marijuana 1.9 to 2.3, p < 0.01). Intentions increased (tobacco 0.4 to 0.8, p = 0.03; marijuana 0.7 to 1.1, p < 0.01). 12.2% initiated tobacco, 13.5% initiated marijuana. Only intention predicted tobacco initiation, while both attitude and intention predicted marijuana initiation. Attitudes, intentions, and behaviors changed significantly towards favored use. Predictors of use varied by substance, suggesting that different prevention approaches may be beneficial.
