Since 2004, and as mandated by World Anti-Doping, WADA has published an annual List of Prohibited Substances and Methods considered as one of the WADA’s International Standards, The List identifies substances and methods prohibited in competition, out of competition and by particular sports. These are classified into different categories (e.g., steroids, erythropoiesis-stimulating agents, genetic doping, etc.).

WADA’s role is to orchestrate consultations prior to the preparation and publication of the List by October 1 with a view to its entry into force on January 1 of the following year.


In consultation with signatories and governments, WADA will establish a monitoring program for substances that are not on the Prohibited List but that it should monitor to determine the prevalence of use in sport.

WADA will publish, before any control, the substances that will be monitored. The presence of these substances or the involved use cases will be reported periodically to WADA by laboratories as statistical data grouped by sport. It will also indicate whether the samples were taken in competition or out of competition. These reports will not provide additional information on particular samples.

WADA will make available to the International Federations and National Anti-Doping Organizations, at least once a year, statistical data grouped by sport on these substances. WADA will implement measures to preserve the greatest degree of anonymity for athletes in these reports. The declared use or detection of monitored substances will not constitute an anti-doping rule violation.
