Brief summary
This study will consist of a six-week open-label treatment period with an extended duration methylphenidate (OROS MPH) followed by subsequent monthly visits for 24 months in a large sample of youths aged 12-17 who meet Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for ADHD. The researchers hypothesize that OROS MPH treatment will be associated with low rates of cigarette smoking in ADHD youth.
Interventions
OROS MPH will be openly prescribed to a maximum of 1.5 mg/kg/day (maximum 126 mg/day). Doses will be titrated according to clinical assessment of efficacy and tolerability.

Outcome results
Cigarette Smoking
Cigarette smoking was assessed by youth self report using a modified version of the Fagerstrom Tolerance Questionnaire (FTQ)
Time frame: 24 months
Population: Clinical trial subjects included in this analysis included those adolescents who took at least one dose of OROS MPH following baseline assessment (N=154), with the last observation carried forward (LOCF) for subjects who did not complete the full study schedule of 24 months
| Arm | Measure | Value (NUMBER) |
