The planning and implementation of the ESPAD 2015 project has been a collaborative effort between the coordination and all the research teams in each participating country. The importance of the ESPAD researchers and their supporting research groups and institutions cannot be overestimated. Since the project cannot provide funding for the data collection in participating countries, it relies on the ability of each principal investigator and ESPAD contact person to raise that money.

Much of the coordination has been supported by the Swedish Ministry of Health and Social Affairs. Its grant has covered costs for holding international meetings, constructing the international 2015 database and producing this report. The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) in Lisbon has co-founded data collection in Georgia, Moldova and Ukraine through the ENP first technical cooperation project (ENPI/2013/325-486), and has covered costs for ESPAD meetings and coordination. Furthermore, the EMCDDA has provided editing, design and production support for this report, the printing and translation of the short version of the report and the updating and hosting of the ESPAD website. Persons at the EMCDDA involved with ESPAD are Paul Griffiths, João Matias, André Noor, Sandrine Sleiman, Rosemary Martin de Sousa and Julian Vicente.

The Pompidou Group at the Council of Europe has supported the project ever since the first project meeting in 1994. In particular, the support of the Pompidou Group has enabled some researchers from eastern and central parts of Europe to participate in meetings. Special thanks are due to Florence Mabileau and Patrick Penninckx at the Pompidou Group for their much-appreciated assistance and support.

A Coordination Committee, consisting of Ludwig Kraus (Germany), Håkan Leifman (Sweden) and Julian Vicente (EMCDDA) coordinated the project in the transition period from 2015 to 2016. A Steering Committee, appointed by the ESPAD researchers at Project Meetings, worked together with the Coordination Committee. All important decisions relating to the planning of ESPAD meetings and the 2015 study have been taken jointly with the Steering Committee. Together with the three members of the Coordination Committee, the Steering Committee consists of Sharon Arpa (Malta), Sabrina Molinaro (Italy), Karin Monshouwer (the Netherlands) and Marcis Trapencieris (Latvia).

The Swedish Council for Information on Alcohol and Other Drugs (CAN) was responsible for collecting country reports and datasets and for constructing the 2015 international database. CAN also produced result tables and texts for the full online version of the ESPAD report 2015, while Ludwig Kraus, Nicki-Nils Seitz and Daniela Piontek edited the shorter print version of the report. The persons at CAN involved with the construction of the database and the production of the digital report are Anna Englund, Ulf Guttormsson, Håkan Leifman, Jonas Raninen (statistical tests) and Johan Svensson.

In addition to the results of the ESPAD 2015 survey, the report also includes data from the ‘Monitoring the future’ project in the United States and from the Spanish national school survey, kindly provided by Lloyd Johnston (United States) and Begoña Brime Beteta (Spain), respectively. Each country was represented in the project by a principal investigator or an ESPAD contact person, who is a contributing author of this report (see title page). In addition, a number of other persons have carried out important work in the context of the 2015 ESPAD study. The main persons from the national research teams in the 35 countries participating in the 2015 data collection are listed below, followed by a list of important funding agencies and supportive organisations.
