All men who are currently smoking daily are selected for final analysis. Quit intention of smoking defines as dependent variable. Knowledge, attitude, practice toward smoking; Heaviness of Smoking Index; Demography define as independent variables. Multivariate logistics model was used.

Results:
The proportion of smokers are interested in quitting smoking following: planning to quit within next month (6.2%); thinking about quitting within the next 12 months (15.5%); and will quit someday, but not the next 12 months (38.5%). High education, good attitude of harming of smoking on health were positively associated with intentions to quit smoking with adjusted odd ratio: 1.70 (1.04-2.75); 1.89 (1.19-2.98), respectively. Reversely, Heaviness of Smoking Index (HIS) with moderate smoking, less supported for taxes rise on tobacco products were negatively associated with intentions to quit smoking with adjusted odd ratio: 0.66 (0.51-0.83); 0.72 (0.56-0.92), respectively.

Conclusions:
