SUMMARYIntroduction: With the growing trend for legalization of cannabis and its derivatives in Serbia, pharmacists are likely to be consulted on the safety, effi cacy, and drug-drug or drug-disease interactions of medical cannabis. Thus, the aim of our study was to assess pharmacy students' knowledge and attitude toward medical cannabis use in Serbia to determine if additional education is needed. Subjects and methods: In the study students from the fi nal year of the study program of integrated academic studies of pharmacy at the Faculty of Medicine, University of Novi Sad were asked to complete an anonymous questionnaire regarding their knowledge and attitudes on the use of cannabis and its derivatives in medical purposes. After giving their written informed consent, they were instructed by the researchers on how to complete the questionnaire. All questionnaires were administered between August 1, 2017 and August 15, 2017. The study was approved by the Ethical Committee of the Faculty of Medicine in Novi Sad; a total of 80 questionnaires were distributed. The questionnaire consisted of 3 groups of statements on which they should mark level of their agreement related to students' knowledge about the use of cannabis and its derivatives in therapeutical purposes, potential negative eff ects, dispensing in a pharmacy and legalization of cannabis and its derivatives in medical purposes.

About 90% of the respondents agreed it is necessary to create clear guidelines for the use of cannabis and its derivatives in therapeutical purposes and 76.3% of the respondents thought that doctor's prescription is necessary for their dispensing in a pharmacy. Most of the respondents (75%) agreed that, based on the experiences of the countries which have
