Introduction: Nowadays, a large number of young people are prone to alcohol consumption. Adolescence is a developmental stage in growing up that involves significant physical, cognitive, emotional, and social changes. Features of adolescence are heightened sensitivity and attention seeking, impulsive behavior, decreased self-control, and proving in society. All of the above contributes to high rates of participation in risky behaviors, including alcohol and drugs consumption. Numerous studies have proven that the early onset of alcohol use, as well as the escalation of drinking in adolescence, is a risk factor for the development of alcohol-related problems in adulthood. Young people in Croatia are at the top of the European average in alcohol and marijuana consumption. Aim: The main aim of the research is to determine the frequency of alcohol consumption in third grade students of the Medical High School in Rijeka Methods: A total of 98 third grade students of the Medical School in Rijeka participated in the research. The research was conducted through an online questionnaire consisting of two parts; in the first part, questions were asked about students' habits related to alcohol consumption, the second part of the questionnaire was related to attitudes and knowledge about alcohol consumption. Results: 75% of students consumed alcohol for the first time between the ages of 14 and 18 22% of students consumed alcohol before the age of 14 and 3% never consumed alcohol. 86% of students consumed alcohol for the first time in the company of peers, 11% of them did so only in the home environment. Most students consume wine and spirits. A small number of students consume beer. Female students consume alcohol and wine more often and male students more often. 89% of students think that alcohol is easily and mostly easily available. Conclusion: Croatia is at the top of the scale in the consumption of alcohol by young people in Europe and therefore requires a serious approach in the design and implementation of prevention programs to reduce this phenomenon and minimize it. Identifying adolescents at greatest risk can help stop the problem before it escalates and leaves long-term consequences.
