Background: There are few studies on the contribution of personality disorder traits to cannabis use disorders in adolescents.
Objectives: The aim of the study was to evaluate the association of personality disorder traits to problematic cannabis use.
Methods: Participants were 111 high school students who completed self-report questionnaires, mainly the Cannabis Use Disorders Identification Test, assessing problematic cannabis use, and the Personality Diagnostic Questionnaire using the scales evaluating personality disorders most often linked to adolescent cannabis use.
Results: A multiple regression analysis showed that personality disorder traits explained a high part of the variance in problematic cannabis use symptoms. Schizotypal and borderline personality traits were positively associated to problematic cannabis use symptoms after adjustment for anxious and depressive symptoms.
Conclusions: This study suggests the importance of evaluating personality disorder traits in studies of risk factors or consequences of problematic cannabis use.

Objective: Racial and ethnic discrimination is a risk factor for substance use among United States adults. However, whether discrimination is associated with substance use disorders (SUDs) overall and by race and ethnicity is less understood.
Methods: We used data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III (n=35,355) and defined past-year discrimination as a summary scale (range: 0-4).

Background And Aims: Evidence from high-income countries has linked duration and compliance with treatment for substance use disorders (SUDs) with reductions in substance use and improvements in mental health. Generalizing these findings to other regions like South America, where opioid and injection drug use is uncommon, is not straightforward. We examined if length of time in treatment and compliance with treatment reduced subsequent substance use and presence of psychiatric comorbidities.
