Leisure time is considered in contemporary literature as a space where numerous asocial behavior occurs. The reason for this is a number of negative impacts, since young people are unable to organize their free time, which is why they are executing them in a desperate, disinterested manner. Therefore, if it does not fulfill the positive contents and offerings that will provide young people with the possibility of self-identification and self-certification, it represents the antisocial bomb. The theoretical framework in which the interpretation of the results is to be found is the determination of free time, leisure time, content and activities of adolescents in leisure time, leisure time as an educational environment, as well as the determination of asocial behavior with risk factors and the most common asocial behaviors. The results of this research were obtained through the implementation of thirteen semi-structured interviews with users of the Home for Children and Youth Rijeka, who use the temporary accommodation service for the purpose of carrying out shorter rehabilitation programs. Based on the results obtained, it is evident that young people often spend their time unstructured, busy with activities of fun and relaxation, while involvement in sport and recreational activities is also visible. The reason for such leisure time implementation is little awareness with the offer of extracurricular activities and the lack of incentive to engage in offered activities. In addition, the reason for unstructured leisure time is partly peers whose influence during adolescence is extremely strong, which is why the influence of parents / guardians is not visible to such an extent.
