Substance use among school dropouts is a growing global concern that has not been assessed through a meta-analysis. This study aims to provide an overview of the relationship between school dropout and substance use. We searched the PubMed, Embase, Web of Science, Cochrane Library, PsychINFO, ERIC (EBSCO), MEDLINE (EBSCO), and CINAHL (EBSCO)…

Adolescent school connectedness generally protects from risk behaviors such as tobacco use; however, its relationship to e-cigarette use is unclear. This study examines the relationship between adolescent school connectedness and e-cigarette susceptibility in a diverse longitudinal sample. This secondary analysis of a school-based intervention…

Diffusion of innovations theory can be used to understand how to prevent or slow the spread of harmful behaviors, such as e-cigarette use in adolescent social networks. This study explores how different network intervention strategies could impact diffusion dynamics through network simulations based on observed social norms and e-cigarette use…

This study aims to assess whether students at schools implementing Project SUCCESS (PS) have different substance use and mental health outcomes than those at schools not implementing PS. Surveys were administered to 18,151 middle and high school students from 29 school districts and 50 schools. Multivariable logistic and linear regressions…

Youth are particularly vulnerable to adverse outcomes from substance use, and there is limited evaluated drug education targeting youth in Canada or the United States of America (US). This scoping review identified and synthesized existing literature on evaluated harm reduction substance use education programs for school-aged youth in Canada and…

Background: Despite recent tobacco control efforts, adolescent vaping remains an epidemic in the United States. The purpose of our study was to understand high school student vaping behaviors using the perceptions of Massachusetts school personnel during the critical window from when the Massachusetts statewide flavor ban legislation was passed in…

Youth vaping is a concern and schools may use many approaches to discipline students caught vaping at school. This study identified the prevalence of school staff seeing vaping in schools and the measures used to discipline students. A state-wide sample of 7,938 staff from 255 middle and high schools reported whether they saw any students vaping…

Background: Tobacco use is known to worsen asthma management. No studies have investigated how trends in youth tobacco use and related harm perceptions vary by asthma status and sex. This study examined these trends among Florida high school students during 2012-2018. Methods: Data from the 2012, 2014, 2016, and 2018 Florida Youth Tobacco Survey…

Background: Mental health care is critical to improving mental health but factors associated with student utilization are poorly understood. Methods: Data were from high school students (N = 2933; mean age = 15.7 ± 0.6) enrolled in a California cohort. We examined associations of sociodemographic factors, substance use, and mental health symptoms…

Background: In 2023, the US state of Texas passed a bill on vaping in school -- House Bill 114 (HB 114) -- which took effect in Texas public schools on 1 September of that year. HB 114 mandates that any student caught vaping in school be placed on a Disciplinary Alternative Education Program (DAEP). The efficacy of HB 114 may be contingent, at…

Objectives: Adolescence is a critical phase of life, involving both risks and opportunities. Preventive health services in this phase contribute to the development of adolescents' models for adulthood. The current study aimed to illuminate adolescents' experiences regarding health education through a patient visit in a hospital, which provides a…

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…

Research has indicated that early sexual intercourse in high school is associated with poor health outcomes such as unintentional pregnancy and sexually transmitted infections (STIs). What is lacking in the research is an understanding of the relationship between even earlier sexual initiation (i.e., before the age of 13) and alcohol, tobacco, and…

The current study assessed whether risk factors associated with vaping were distinct from risk factors associated with other substance use (e.g., alcohol, cannabis) during adolescence. Participants (N = 848, ages 10-16 years) completed a self-report survey to assess frequency and age of onset of substance use, risk perceptions of use, risk factors…

Substance use in adolescence is a significant public health issue, particularly in early-to-mid adolescence, which represents a window of risk in the etiology of substance abuse and dependence. Substance use during this development period often results from affiliation with deviant peers, who model, facilitate, and reinforce use. Existing…
