The World Anti-Doping Agency (WADA) has published the 2008 list of prohibited substances and methods. It will come into effect on 1st January 2008.
All persons who participate in any event in the WCF member associations that have or have purported to be signatories to the WADA Code should be aware of the new requirements.
To date the following members are known or are believed to be signatories:
Participation in any of the above jurisdictions and particularly at the forthcoming WCF 11th Association Croquet World Championship in New Zealand 2008, may attract doping controls.
For details of the new requirements see the WCF Anti-Doping page www.wcfcroquet.org/Organisation/anti-doping.html
Martin Murray adds: It may be of interest to some croquet players to read section P2 of the list, which refers to beta-blockers. These are prohibited only in a restricted list of sports, under which croquet is not included.
My interpretation is that beta-blockers are therefore not on the prohibited list. Even if they were (and I don't anticipate the WCF, or any national association, putting them on the list), it would still be open for a competitor to apply for a therapeutic use exemption.
