The World Anti-Doping Agency (WADA) Prohibited List outlines the classes of substances and methods that are prohibited in sport, including rugby union.
A new list is published by WADA on January 1 every year. Substances and methods can be prohibited if they meet any two of the three following criteria:
- Evidence that the substance or method enhances or has the potential to enhance performance;
- Evidence that the substance or method represents an actual or potential health risk to the athlete;
- WADA's determination that use of the substance or method violates the spirit of sport.
A summary of the modifications to the Prohibited List for 2012 is also available.
WADA has also established a monitoring programme for substances that are not on the Prohibited List but which are monitored closely to detect patterns of misuse in sport. A range of substances have been placed on the WADA 2012 monitoring programme.
