The theoretical part of this paper provides an overview of theoretical concepts related to the notions of adolescence, risky behaviours, drug addiction and prevention. Results of the relevant research related to the topic of the paper are also presented. In the theoretical part it is also explained what makes adolescence specific and which behaviours are considered to be risky. Consumption of drugs that can lead to addiction (which is considered to be behavioral disorder) is especially emphasized. It is also explained which forms of prevention exist and how successful prevention programs should look like. The empirical part of the paper provides a description of the methodology that was used to examine what adolescents think about drug addiction prevention. The main goal of this paper is to show perspective of the adolescents in relation to drug addiction prevention. For the purpose of this paper, a quantitative research was conducted on a sample of adolescents that attend secondary school in the Republic of Croatia, and a survey questionnaire was used to collect data. The results showed that most adolescents participated in lecture-based prevention programs that were conducted by the police, pedagogues or psychologists. The results also show that adolescents are indifferent to school-based and community-based prevention but they agree that prevention is important within their families. Respondents also believe that they are able to resist peer and celebrity influence when it comes to drug abuse. Most commonly consumed drug among the respondents is marijuana or hashish. According to the results, gender and class are significant predictors when it comes to the temptation associated with trying drugs and drug consumption. These results can be used to improve drug addiction prevention programs, as well as for further research related to this issue.
