This research was aimed to compare the brain / behavioral systems (BIS/BAS) of smokers and nonsmokers. For this respect, 124 students (62 smokers and 62 nonsmokers) of Tabriz University were selected and then responded to Carver and White’s BIS/BAS scale. Data were analyzed by independent samples t test. The results revealed no differences in BAS as a whole, and subscales of drive and rewarding responses, but there were differences in subscale of fun seeking (pro smokers) and BIS (pro nonsmokers).
