There was a significant difference between the quality of life in smokers and non-smokers and the quality of life was significantly lower among smokers compared to non-smokers (p < 0.001) . This difference was observed in the dimensions of general health (p < 0.001), cheerfulness (p < 0.001) and social performance (p = 0.014) as well as in two general dimensions of physical (p = 0.001) and mental (p < 0.001) quality of life. In the present study, smoking cigarette (OR=1.54, CI 95%: 1.31-1.81) and hookah (OR=1.32, CI 95%: 1.11-1.56) were considered as risk factors for low quality of life.
