Conclusions
This study used an online survey-based experiment among ever-smoker university students in Ankara, Turkey. No individual differential effect of PP or harsher GHWs was found on intentions to quit when respondents were exposed to images on a screen. However, PP and harsher GHWs were found to be effective in generating negative affect and avoidant responses.Smoking incurs substantial health costs. The findings of this study imply that further work is needed for effective tobacco control among youth during critical years of tertiary education.
