Randomized Controlled Trial Clinical TrialThe smoking cessation efficacy of varying doses of nicotine patch delivery systems 4 to 5 years post-quit day.
This study was undertaken to evaluate the long-term smoking cessation efficacy of varying doses of transdermal nicotine delivery systems 4 to 5 years post-quit day. ⋯ Nicotine patch therapy with 21 mg/day patches resulted in a significantly higher long-term continuous abstinence rate compared to lower dose patches and placebo. Relapse rates among the various treatment conditions were similar after 1 year postcessation.
