In the past adolescents with cannabis abuse have been excluded from studies in which atomoxetine for ADHD symptoms was studied. In this study the efficacy of atomoxetine on symptoms of ADHD in adolescents with ADHD and comorbid cannabis abuse will be studied.
The purpose of this study is to determine whether atomoxetine is effective in reducing ADHD (Attention Deficit/Hyperactivity Disorder) symptoms in adolescents with ADHD and comorbid cannabis abuse.
