Towards a New Dynamic Interaction Model of Adolescent CUD Manifestation, Prevention, and Treatment: A Narrative Review.

Background: Cannabis is one of the most popular drugs of the 21st century, especially among adolescents and young adults. Evidence of a variety of lasting neuropsychological deficits as a result of chronic cannabis use has increased. Furthermore, regular cannabis use is found to be a predictor of mental health problems, less motivation in school, and school dropout. Aim: Our goal is to propose a theoretical model of adolescent cannabis use disorder (CUD) based on Zinberg's drug, set, and setting model and explicated by a review of the literature on adolescent cannabis use to improve the prevention and treatment of CUD for adolescents. Methods: PubMed and Web of Science were searched for relevant publications as part of a hypothesis-based and model-generating review. Results: Individual (set) and environmental (setting) risk factors play important roles in the development of CUD in adolescents. School performance, motivation, and attendance can be negatively influenced by persistent cannabis use patterns and adolescent brain development can consequently be impaired. Thus, cannabis use can be understood as both being the cause of poor school performance but also the consequence of poor school performance. To prevent and reduce adolescent CUD the drug, set, and setting must all be considered. It is important to notice that the multiple feedback loops (indicated in our dynamic interaction model) are not mutually exclusive, but offer important intervention focus points for social workers, addiction professionals, parents, and other care takers. Conclusion: We argue that the three dimensions of drug, set, and setting contribute significantly to the eventual manifestation of CUD. Based on our dynamic interaction model, recommendations are made for possible preventive and therapeutic interventions for the treatment of adolescents and young adults with CUD.

Substance use prevalence rates among migrant and native adolescents in Europe: A systematic review.

ISSUES: Migrant adolescents show specific risk and protective factors associated with substance use, but the extent to which prevalence rates differ between migrant and native-born youth in Europe remains unclear. The present study aims to provide a comprehensive review of all available substance use prevalence studies on differences in substance use between migrant and native-born adolescents in Europe. APPROACH: In this systematic review, PubMed, Medline and Pre-Medline, EMBASE and PsycINFO were searched for articles comparing substance use prevalence rates (tobacco, alcohol, illicit drugs) between migrant and native-born adolescents or young adults aged 11 to 29 years in European countries. The Joanna Briggs Institute prevalence critical appraisal tool was used for quality assessment. KEY FINDINGS: Fifteen studies met the inclusion criteria. The findings unanimously showed lower alcohol use in migrant compared to native-born adolescents, in particular among migrant adolescents from non-European countries and/or with a Muslim background. For tobacco and illicit drug use, findings were mixed. IMPLICATIONS: The results suggest a healthier behaviour profile among migrants than among native-born adolescents regarding alcohol use. Therefore, it would be beneficial to develop interventions to support migrant communities in maintaining their healthier alcohol use practices upon arrival in the host country. CONCLUSION: Compared to native-born adolescents, migrant adolescents are less likely to use alcohol. The findings on tobacco and illicit drug use were mixed. A European standard for surveys regarding substance use among adolescents is needed to investigate fluctuations, causes, and consequences of substance use differences between migrants and natives at the European level.

Toward a New Model of Understanding, Preventing, and Treating Adolescent Depression Focusing on Exhaustion and Stress.

OBJECTIVE: Adolescent depression is a heterogeneous disorder, with a wide variety of symptoms and inconsistent treatment response, and is not completely understood. A dysregulated stress system is a consistent finding, however, and exhaustion is a consistent trait in adolescent patients. The aim of this paper is to critically assess current hypotheses in adolescent depression research and reframe causes and treatment approaches. METHODS: A mixed-method approach involved a review based on publications from PubMed, Embase and PsycInfo, and two exemplary adolescent cases. RESULTS: Both cases show a spiral of stress and exhaustion, but with a different profile of symptoms and coping mechanisms. Reframing both cases from the perspective of coping behavior, searching for the sources of experienced stress and exhaustion, showed coping similarities. This proved essential in the successful personalized treatment and recovery process. In combination with recent evidence, both cases support the functional reframing of depression as the outcome of a stress- and exhaustion-related spiralling mechanism. CONCLUSIONS: We propose to open up a symptom-based, mood-centered view to a model in which adolescent depression is framed as a consecutive failure of stress coping mechanisms and chronic exhaustion. Addressing exhaustion and coping primarily as a treatment strategy in adolescents and young adults might work in synergy with existing treatments and improve overall outcomes. This perspective warrants further investigation.
