The European School Survey Project on Alcohol and Other Drugs (ESPAD) collects comparable data on substance use among 15-16-year-old students since 1995. The purpose of the study is to monitor substance use behavior in adolescents in as many European countries as possible. With next year's data collection the observation period in those countries that have participated in ESPAD since the projects start will encompass 20 years, and analyses of temporal changes can then be based on six measurement points.
