Psychological Characteristics in Patients during Treatment for Tobacco Dependence.

It is known that tobacco/nicotine dependence causes cognitive, behavioral, and physiological symptoms, and smoking cessation affects mood in smoking patients.1, 2 The status of mood was reported to be worse in smokers than in nonsmokers.3 Many studies showed the moderate effects of smoking cessation treatment programs on physiological function; however, few studies compare mood in smoking cessation patients and that in smokers and estimate the effects of the program on the status of mood. We investigated whether mood in patients with tobacco dependence improved through the Japanese 12-week standard program for smoking cessation comparing smokers and nonsmokers.
