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.

Check your medications

Even common medications can contain banned substances.

That's why we encourage you to check every medication on Global DRO before using it. Global DRO can tell you if a substance is banned in sport, permitted, or has conditions around its use.

As an athlete, you're 100% responsible for anything found in your sample - so it's always best to play it safe.
