Study Summary

The objective of this study is to evaluate whether Osmotic-Release Methylphenidate (OROS MPH), relative to placebo, increases the effectiveness of standard smoking treatment (i.e., nicotine patch and individual smoking cessation counseling) in obtaining prolonged abstinence for smokers with Attention Deficit Hyperactivity Disorder (ADHD).

Primary Outcome

The smoking quit date was considered the first day of the O-MPH/P-Stnd Smoking Tx phase, which lasted for 6 weeks or more precisely 42 days (i.e., approximately weeks 5-10). The grace period was the first two weeks (i.e., days 1-14) with the remaining four weeks (days 15-42) comprising the period in which the participant must not meet criteria for treatment failure in order to be scored as obtaining prolonged abstinence. Self-report of cigarette use was assessed using a time-line follow-back (TL
