Young people constitute one fifth of world population. Youth's reasons for smoking include looking for excitement, getting away from problems and meeting emotional and social needs. Smoking addiction is the most common addiction among young people especially due to the fact that cigarettes are sold legally, and it is known that one out of two young people who try smoking become addicted. Being knowledgeable about youth's smoking addiction will also raise the effects of health education activities. This study aims to evaluate the smoking addiction levels of university students who smoke. Thus, it uses survey model- which is one of quantitative research methods.
