The purpose of this research was to determine the smoking habits of students who receive nursing education in universities and their personality traits. We found that 29.2% of the students were habitual smokers, and the average score on the Fagerström Nicotine Dependence Test was 3.4 ± 2.3. A significant difference in statistical terms was marked between the participants' smoking habits and the self-control factor. Because we found that the level of smoking among individuals with high self-control is rather low, providing information to students on quitting smoking and periodically assessing smoking status are recommended. In addition, individual improvement programs focused on the development of self-control can be added to nursing curricula.
