Background & Significance ADHD 3-5x more common in adolescents with SUD (30-50%) compared to those without SUD (7-10%) and is associated with poorer treatment outcomesADHD 3-5x more common in adolescents with SUD (30-50%) compared to those without SUD (7-10%) and is associated with poorer treatment outcomes The safety and efficacy of psychostimulant medication for ADHD in youths without SUD is well-established, but research is lacking in substance abusing adolescents with ADHDThe safety and efficacy of psychostimulant medication for ADHD in youths without SUD is well-established, but research is lacking in substance abusing adolescents with ADHD

28. Summary of Main Study Findings 1.ADHD outcomes as good or better than in adolescents without SUD 2.OROS-MPH safe, well-tolerated 3.Results suggest contribution of CBT to both SUD and ADHD outcomes 4.Substance outcomes as good or better than in youth with less severe psychopathology 5.Treatment compliance, completion superior to that reported in studies of youths with less severe SUD and psychopathology

29. Interpretation of Results in Context of Previous Research Results are inconsistent With most controlled trials of psychostimulant vs placebo (alone) for ADHD Results are consistent With 3 controlled psychostimulant trials in adults concurrently receiving weekly individual CBT for SUD (Levin et al 2006; 2007; Schubiner et al 2004) With growing literature that cognitive behavioral and behavioral interventions effective for ADHD in adults and youth without SUD (Safren et al, 2005; Fabiano et al, 2009; Solanto et al, 2010)

30. If replicated, results have important clinical implications Results suggest that clinically significant reductions in co- occurring ADHD symptoms may be important in helping adolescents achieve greater abstinence during substance treatment. In the context of individual CBT (for SUD), significant reductions in ADHD symptoms may occur with or without pharmacotherapy. If ADHD does not improve early in treatment, OROS-MPH may be considered as safe and likely effective pharmacotherapy for ADHD even if not yet abstinent (with regular monitoring and in the context of ongoing substance treatment) OROS-MPH demonstrated low abuse/diversion liability. Secondary outcomes indicated some added benefit with OROS-MPH compared to placebo
