Scheduled reduced smoking: Effects on smoking abstinence and potential mechanisms of action

Although most smokers in our society report that they would like to quit, smoking prevalence rates have remained relatively unchanged during most of the 1990s. This is in contrast to a nearly 50% reduction in prevalence observed over the past 3 decades. Presently, an estimated 25.5% of adults (48 million people) continue to smoke, although most smokers would like to quit. Recent research on the treatment of nicotine dependence has focused primarily on events that occur after the initial cessation period (i.e., the prevention of relapse with behavioral counseling and/or the management of withdrawal symptoms with nicotine replacement therapy). Although these methods are effective, there is evidence that cessation rates may also be enhanced by manipulating smoking behavior prior to quitting. One promising approach is scheduled reduced smoking. Early work with this approach has yielded superior abstinence rates compared to gradual reduction and abrupt ''cold turkey'' quitting techniques. In this article, we present an overview of research on scheduled reduced smoking and discuss the effects of the treatment on smoking urges, negative affect, and self-efficacy.
