Treatment With Quetiapine for Youth With Substance Use Disorders and Severe Mood Dysregulation

This study proposes to use quetiapine as an adjunct treatment to treatment as usual to improve both substance use disorder (SUD) and mood symptoms in youth with SUD and severe mood dysregulation (SMD). This is a randomized, double blind placebo controlled parallel design study. Youth with symptoms of mood dysregulation and active substance use that meets criteria for a SUD will be randomized to adjunct treatment with quetiapine or placebo. The investigators hypothesize that treatment with quetiapine will lead to a reduction in substance use, improvement in mood, and lead to greater engagement in outpatient treatment.
