It is amazing how much a person is capable of doing something with his own body and with the power of the mind. This is exactly what we often witnessed in sports. Athletes achieve amazing success with their talent, effort, sacrifice and perseverance. Most of them strive to achieve even better results that are proof of their commitment. More precisely, they strive for excellence. However, not all athletes can progress to the level they would like, or they are unwilling to take the necessary steps to achieve what they want. Thus, some athletes decide to use certain substances and methods that improve their physical performance, i.e., doping. The issue of doping is being ethically debated between those who believe that its use should be allowed and those who oppose it. The debate between the libertarian and essentialist perspectives is based on four arguments – the Argument of Paternalism, Argument of Harming Self and Others, Argument of Unfair Advantage and Argument from Coercion. In order to examine the attitude of students of the Faculty of Croatian Studies at the University of Zagreb towards doping in sport, a quantitative research was conducted using a survey method during June and July 2021 and was attended by 117 participants. The obtained results indicate that students have extremely negative attitudes towards doping in sport. However, no statistically significant association was found between sociodemographic characteristics of the participants and attitudes about doping, as well as the association between the attitudes of the participants and their practice of sport activities.
