Controlled smoking: single case study with multicomponent intervention.

The case study of controlled smoking treatment reported here includes multicomponent behavioral interventions. Follow-up data of 30 months' duration are examined with particular reference to shifts in topographical aspects of smoking and a focus on other health-related behaviors. Cigarette smoking was reduced by 85% without compensatory shifts in topography and with successful long-term maintenance. The need to specify detailed ingredients of multicomponent smoking packages for individual clients is discussed, paying particular attention to the potential for development of "positive addictions".
