A sample of 165 study subjects consisting of 68 ex-smokers who were successful in smoking cessation and 97 smokers who were unsuccessful in smoking cessation, by snowball sampling. The dependent variable was smoking cessation. The independent variables were intention to quit smoking, attitude toward smoking cessation, outcome expectation, addiction, stress, perceived behavioral control (PBC), subjective norm, social support, family income, purchasing power, smoking duration, and access to cigarette. The data were collected using questionnaire and analyzed using path analysis. Results: Successful smoking cessation was directly affected by strong intention (b= 2.39, SE= 0.51, p <0.001), duration of smoking (≥10 years) (b= -3.46; SE= 0.57; p <0.001), and easy access to cigarettes (b= -1.28; SE= 0.52; p= 0.008). Intention is was affeced by positive attitude (b = 0.79, SE= 0.39, p= 0.046), positive PBC (b= 1.89, SE= 0.40; p<0.001), high purchasing power (b= -1.23; SE= 0.39; p= 0.002), and positive subjective norm (b= 1.38; SE= 0.40; p= 0.001). Positive PBC was affected by duration of smoking (≥10 years) (b= -2.32; SE= 0.47; p<0.001), positive outcome expectation (b= 1.04; SE= 0.49; p= 0.035), and addiction (b= -2.96; SE= 0.49; p
