Prohibited substances

The Prohibited List is published by the World Anti-Doping Agency (WADA). It details all substances and methods that are prohibited or banned in sport, and is updated every year on January 1.

A substance or method may be included on the list if it meets any two of the following criteria:

• it has the potential to enhance sporting performance
• it presents an actual or potential health risk to the athlete
• it violates the spirit of sport.
