Objective: Among two-year college students, alcohol and marijuana use, related consequences, and risk factors for use are not well understood. We examined differences between two- and four-year students in alcohol and marijuana use, consequences, and perceived descriptive norms, and explored whether two-year status moderated associations between…

Polysubstance use is associated with myriad short- and long-term health outcomes. Although prior research has documented differences in polysubstance use between lesbian, gay, bisexual, transgender, queer/questioning, and other sexual and gender minoritized (LGBTQ +) youth and their heterosexual/cisgender counterparts, as well as between subgroups…

Objective: The purpose of this study was to examine patterns of concurrent cannabis and other substance use and their differential associations with cannabis-related problems and academic outcomes in college students. Participants: Participants were undergraduate students (N = 263; M age = 19.1 years; 61.2% female) who were eligible if they used…

Objective: The role of simultaneous alcohol and marijuana (SAM) use in the experience of blackouts among college students is unclear. To clarify discrepancies, the current study evaluated whether the association between SAM user status and blackouts was moderated by high-intensity drinking (HID). Participants and Methods: College students (N =…

The study's aim was to determine the association between school-based violence and being under the influence of drugs/alcohol during the last sexual intercourse among US high-school adolescents. A total of 3136 students from the 2019 Youth Risk Behavior survey were included. Multivariate logistic regression models were conducted to examine…

Medication for attention-deficit/hyperactivity disorder (ADHD) is frequently abused and misused alongside alcohol on college campuses. The aim of the study was to assess the relationship between participants' alcohol use, mental distress, and academic performance in relation to their illicit use of ADHD medication. An anonymous cross-sectional…

Attention-deficit/hyperactivity disorder (ADHD) is characterized by persistent patterns of inattention, hyperactivity, and impulsiveness. Among US children and adolescents aged 3-17 years, 9.4% have a diagnosis of ADHD. Previous research suggests possible links between parental substance use and ADHD among children. We conducted a systematic…

Background: To determine if school engagement is a viable target for early prevention of adolescent substance use, this study investigated whether school engagement in early adolescence (ages 12-14) is a cause of alcohol and cannabis use during middle to late adolescence (ages 15-19). Methods: To facilitate causal inference, inverse probability of…

It is important to prioritize intersectoral action at schools to prevent the use of alcohol and other drugs. This strategic act should be organized with multidisciplinary learning characteristics and with the involvement of different stakeholders. The aim of a recent scoping review was to identify the factors that benefit and hinder intersectoral…

The present study tested the effects of gender, alcohol consumption, and leaving a party together, in isolation and in interaction, on perceptions of sexual intent. Participants: Undergraduates (N = 438) completed an online survey between Winter 2017 and Winter…

We investigate the mechanisms by which a student's age relative to classmates (i.e., relative age) influences risky health behaviors among European adolescents. Using a two-stage least squares approach, we show that relatively young students are more prone to engage in risky behaviors. These results hold after controlling for absolute age, country…
