The European School Survey Project on Alcohol and Other Drugs (ESPAD) data explorer tool allows access to years of ESPAD data on substance use among 15-16-year-old students. ESPAD is the largest cross-national research project on adolescent substance use in the world, bringing together independent research teams in over 40 European countries. Developed by the National Research Council of Italy (CNR), the tool holds data collected between 1995 and 2024.

The purpose of the tool is to make ESPAD data available to a wide range of interested stakeholders, from the general population, journalists and teachers to prevention experts and scientists. Data are exclusively displayed in aggregated form by countries participating in the study and by year of the study. Specific statistical measures (e.g. frequency distribution and prevalence rates) are calculated before visualisation, by means of charts.
