Introduction:  Impulsivity, especially in smoker’s students, is one of the psychological factors for future high-risk behaviors. This study was performed to compare impulsivity and personality characteristics of smokers and non-smokers male students who live in a dormitory.
Materials and Methods: The study population of this causal-comparative study consists of all Razi University male students of Kermanshah city who live in a dormitory and studying in the second semester of the academic year 2015-2016. The students were selected through a convenient method (400 smokers and 200 non-smokers). Research instrument included Cloninger Personality Inventory (TCI), Barratt Impulsivity Scale (BIS-11), modified Fagerstrom Tolerance Questionnaire (mFTQ), and Balloon Analogue Risk (BART). Data were analyzed by SPSS software version 22, using descriptive statistics and discriminant analysis test.
Results: The research findings indicated that smokers with high and low dependency and non-smokers in components of motor impulsivity, reward dependence, indecision, and novelty-seeking are significantly different (P<0.05).
  Conclusion: Based on the findings, it seems that factors such as motor impulsivity, reward dependence, indecision, and novelty seeking can discriminate among low and high-dependent smokers and non-smokers.
