Addiction

Department of Psychiatry, University of Vermont, Burlington, Vermont, USA.
Background And Aim: Cannabis use disorder (CUD) is strongly influenced by genetic factors; however the mechanisms underpinning this association are not well understood. This study investigated whether a polygenic risk score (PRS) based on a genome-wide association study for CUD in adults predicts cannabis use in adolescents and whether the association can be explained by inter-individual variation in structural properties of brain white matter or risk-taking behaviors.
Design And Setting: Longitudinal and cross-sectional analyses using data from the IMAGEN cohort, a European longitudinal study integrating genetic, neuroimaging and behavioral measures.

Background: Implementation of tobacco advertising, promotion and sponsorship (TAPS) bans and of health warning mandates varies by country, and their impact on adolescents' exposure to tobacco-related messages is not well understood, particularly in low-income and middle-income countries.

Introduction: Hospitalisation represents an opportunity to identify and treat e-cigarette use among adolescents and young adults (AYAs). Knowledge on how to provide this care is lacking. We aim to fill this gap by developing an e-cigarette use intervention and evaluating preliminary efficacy and implementation outcomes among hospitalised AYAs.

Background: School-based substance use prevention is important, yet many educators are not trained in the curriculums. The purpose of this study was to assess changes in educators' knowledge about substances and confidence in delivering drug education before and after participating in educator trainings, as well as overall perceptions of the trainings, for three curriculums: tobacco, cannabis, and all drugs prevention.
Methods: We conducted one-arm pre-post analyses evaluating educators' changes in knowledge about products and confidence to deliver curriculums.
