Prohibited substances
The Prohibited List

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.
The information below gives you an overview of the kinds of substances and methods that are banned in sport, but we advise you to check the full List on the WADA website.
