Background . It has been suggested that the remaining smoking population may be composed of individuals who are becoming increasingly challenging to treat. Irvin and colleagues (2000, 2003) reported a significant decrease in abstinence rates over time among published clinical cessation trials. Their findings are consistent with the theory that the smoking population is becoming increasingly hardened, but may not be generalizable. Objectives . To assess how smoking cessation clinic participant characteristics and quit rates have changed over time. Methods . Prospective survey data collected from approximately 3,400 participants who attended Roswell Park Cancer Institute's Stop Smoking Clinic between 1982-2004 was analyzed to ascertain changes in participant characteristics and smoking behavior. In 2004, participants were also re-contacted to provide a retrospective history of their smoking behavior since enrollment in the clinic. Results . Clinic participants have become increasingly older and non-white over time. A significant decrease in daily consumption of cigarettes was observed, yet there was no change in the proportion of participants reporting smoking within 30 minutes of waking.
