Adolescent substance use is a top national public health concern with approximately 50% of youth having tried an illicit substance by the end of high school. The transition to high school is a critical point for substance use initiation. Despite this fact, there is relatively limited research looking at factors that can protect students from…

Adolescence is a period of growth, independence, and exploration, with increased curiosity and risk-taking behaviors (Centers for Disease Control and Prevention [CDC], 2021b). Evidence has shown an increase in mental health concerns during adolescence, including suicidal behaviors (CDC, 2023b; Plemmons et al., 2018; Yard et al., 2021), as well as…

Many studies have been conducted in Africa on the use of psychoactive substances among high school students. However, few studies have examined the psychological mechanisms underlying this consumption. Grounded in self-determination theory (SDT), the present study explored the moderating role of the frustration of basic psychological needs on the…

Background: While a theoretical association between religiosity and substance use is anticipated, there is limited empirical evidence testing this theoretical proposition among Nordic adolescents. It was anticipated that studying these substance-use correlates from a criminological perspective by employing a large sample of students could provide…

Using cannabis (e.g., smoking marijuana) is becoming popular, partly due to a legalization trend across different countries. This tendency has resulted in cannabis consumption being accepted by society as if it were harmless. However, evidence shows that the use of this drug has detrimental effects on cognitive, academic, and professional…

Little is known about the implications of cannabis legalization on adolescent health behaviors. This study sought to examine the relationship between recreational cannabis legalization and adolescent sexual risk behaviors. Data on 371,487 respondents who have ever had sexual intercourse from 41 states in the 2005 to 2019 Youth Risk Behavior Survey…

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…

Rates of suicidal thoughts and behaviors (STB, i.e., suicidal thoughts, plans, and attempts), substance use, and bullying victimization are higher among lesbian, gay, bisexual, transgender, and/or queer (LGBTQ+) youth compared to their heterosexual peers. However, research examining the interactive and potentially compounding associations of…

Because studies examining youth drug use often have data with a high proportion of zeros, they often do not meet the assumptions for univariate or linear regression analyses that are typically used. We demonstrate the use of zero-inflated negative binomial regression models to address excessive zeros in drug use frequency on perceptions of…

Purpose: This study explored differences between lesbian, gay, and bisexual (LGB)-housed and homeless students regarding substance use patterns on and off school grounds and the unique contribution of homelessness to substance use in school. Methods: Data were from the 2013-2015 California Healthy Kids Survey, a statewide survey of school…

A growing body of literature suggests that youth with severe obesity are engaging in substance use. The purpose of the present study was to examine profiles of substance use among adolescents with severe obesity and examine how these profiles are associated with depressive symptomology using data from the Youth Risk Behavior Surveillance System.…

This study examined how schools prioritize ten key health concerns among their student populations over time and whether schools' prioritization of alcohol and other drug use (AODU) corresponds to students' substance use behaviours and cannabis legalization as a major policy change. Data were collected from a sample of secondary schools in…

Background: Boys use cannabis at a younger age and more frequently than girls. It has been suggested these sex differences might vary according to students' relationship to school. We explored whether the association between sex and adolescents' cannabis use varies among schools and according to students' school connectedness. Methods: The study…

Objectives: Survey items used in surveillance systems to assess the use of emerging products like hookah and electronic inhalant devices (EIDs) may not match definitions used by high-risk populations. This qualitative study explored how African American youth and young adults (YYAs) (1) use hookah and EIDs and (2) identify patterns in the ways…

A primary community prevention approach in Iceland was associated with strong reductions of substance use in adolescents. Two years into the implementation of this prevention model in Chile, the aim of this study was to assess changes in the prevalence of adolescent alcohol and cannabis use and to discuss the impact of the COVID-19 pandemic on the…
