The ECDD Information Repository is an open access database containing publications and information on psychoactive substances reviewed by the WHO Expert Committee on Drug Dependence (ECDD).

The purpose of the repository is to provide the public, academics, health professionals, law enforcement and government staff an easy interface to find technical information about psychoactive substances that have been reviewed by the ECDD. Users are able to search and extract information from published Technical Reports, Critical Review and Pre-review reports. In addition, the repository provides an overview on the recommendations proposed by the WHO to the international community and the current scheduling status of each psychoactive substance reviewed.
