简要总结
The purpose of this study is to evaluate the extended pharmacological and psychological treatment for chronic cigarette smokers.
详细描述
The work adapts interventions that have been successful in the general populations, and tailors them to chronic smokers, who may have numerous previous smoking treatment failures. If successful it will: (1) make available a treatment intervention that produces hight long term abstinence rates; (2) provide information on variables that predicts success and failure in this population of smokers; (3) examine the cost-effectiveness of more intensive, longer term treatments.
