CONFLICT OF INTEREST: NONE DECLARED Day Hospital is an alternative to inpatient treatment as a transition from hospital to outpatient type of treatment, especially for those patients who cannot quickly return to the family, and patients who are unable to leave the usual social contacts so to them the hospitalization will pose a great mental risk. The aim of the research is to determine the structure of psychiatric morbidity, as well as demographic features and duration of hospitalization in patients treated at a Day Hospital of Psychiatric Clinic in Sarajevo during the period 2006-2007. The survey is conducted at the Psychiatric Clinic, Clinical Center of Sarajevo University as retrospective, based on observations of certain variables (gender, age, hospitalization duration), and the number of diagnosis. The results of the research show that the total number of registered patients in the observed period is 400. During the two year study there were more female (61.3%) than male patients (38.7%). Also, during the two years of research, most of those were with one diagnosis. The average hospitalization duration was 45 days, and the most often hospitalization duration was from 1 to 3 months. During both years, mostly present was the population in age group 46 to 65 years, followed by age group 26 to 44 years. Leading diseases during both years of research were from the group F30-F39, and the most common co-morbid diseases from groups: F30-F39, F40-F49 and F60-F69. We can conclude that Day Hospital has great significance in the mental health prevention. Daily structured program provides hospital diagnosis, treatment and rehabilitation of persons of both genders from different age groups and with diverse psychopathology.

It is a well known fact that drug abuse is most common in early adolescence. The most popular substances among youth are cannabis products (made from Cannabis sativa L., Cannabaceae). The majority of heroin and cocaine addicts have started with marijuana. The aim of this study is to show some psycho-social characteristics of adolescents who abuse cannabis. Research conducted during the year 2001 was epidemiological and prospective. The study group included 600 adolescents of equal gender and age distribution. Q 2000 questionnaire was used, as a comprehensive tool for all aspects of adolescent life. The results show strong peer impact on one's behavior. Youth who use cannabis had 2-3 friends of the same behavior, compared to others who had none. We found positive correlation between life stressful events and cannabis abuse. We also noticed tendency to delinquent behavior related to cannabis abuse (35%).
