The subject of this sociological research is the perception of drug addiction among young people in the city of Split. The research was conducted in June 2021 on a sample of adult residents up to 29 years of age in the city of Split using a survey method where data was collected through an online questionnaire, given the specific situation of the coronavirus pandemic. The link to the online questionnaire was posted on various Facebook groups, forums and social networks, and 302 participants participated in the survey. The results showed that most respondents had tried at least one type of illegal drug at least once in their lives, but the three most commonly consumed drugs were marijuana, hashish, and cocaine. Data show that as the average grades in high schools decreases, the percentage of students who tried some type of drug increases, that there is a connection between family addiction and drug addiction, and that the respondent is more likely to experiment with drugs if peers in the immediate vicinity consume the drug. On the other hand, no statistically significant difference was observed between men and women in terms of illegal drug use, and it was shown that there is no dependence of monthly household budget and propensity to use drugs. At the end of this research it can be concluded that drug use is very widespread in the city of Split among young people and that there are various motives why young people resort to drugs, and that it is necessary to increase the number of prevention programs in Split and throughout Croatia
