Substance use in childhood and adolescence and its associations with quality of life and behavioral strengths and difficulties

This is the authors' abstract. We don't add key points for this paper.

The results show that quality of life and behavioral difficulties are associated with substance use and should be considered when developing or implementing preventive measures to counter substance use. Furthermore, the findings indicate that substance use can be accompanied by improved peer relations. Therefore, the influence of peers, especially of peers who use these substances, should not be underestimated.
