Drug-related research in Croatia has expanded in recent years; it now includes all main research fields and is mainly implemented by government agencies and universities. A number of surveys estimating the prevalence of the use of illicit substances have been conducted with financial support from the Office for Combating Drug Abuse of the Government of the Republic of Croatia, the European Monitoring Centre for Drugs and Drug Addiction, the Croatian National Institute of Public Health, the Ministry of Health and country- and local-level institutions. Since 2011, regular studies on the quantitative identification of selected urinary biomarkers of illicit drugs in wastewater have been implemented in Zagreb. Studies on the availability and price of drugs and on estimating drug-related public expenditure have also been carried out.
The libraries and websites of the Ministry of Science and Education, as well as of funding and research agencies, are the main channels for disseminating drug-related research findings.
