The number of narcotic drug addicts is increasing. People who start using narcotic drugs constantly increase their quantity because of tolerance growth and the creation of addiction. Over time, addicts become dysfunctional. Treatment and resocialization enable the establishment of adequate psychosocial functioning of addicts. Nurses are team members who participate in the treatment of addicts and their resocialization. The goal of this bachelor thesis was to examine the knowledge of Nursing students about narcotic drugs, because through their work, students will have the opportunity to be in contact with addicts. The research was conducted at the Faculty of Health Studies in Rijeka. In total, 103 students of the first, second and third year of full-time and part-time undergraduate professional Nursing studies participated in the research. Responses were collected through a survey created in Google forms. The survey was sent via Microsoft Outlook email to representatives of the first, second and third year of Nursing study. The survey was conducted completely anonymously and the answers and results are also anonymous in according with the law on personal data protection. The research showed a difference in the knowledge abut narcotic drugs between students of the first and third year of studies, from which it can be concluded that faculty education enriches the knowledge of Nursing students, this confirming hypothesis 1. On the other hand, this research did not confirm hypothesis 2, since parametric tests have measured the same level of knowledge of full-time and part-time students, while non-parametric tests measured a greater amount of knowledge in full-time students. Research like this is good for checking the amount of knowledge that nursing education provides to students. It would certainly be desirable to do more research like this as a source of information for the improvement of nursing education.
