Cricketers can be tested out of competition for the first time under a new anti-doping code announced this week by the International Cricket Council (ICC).

The rules, revised after amendments to the World Anti-Doping Agency (WADA) code and unanimously approved by the ICC Board, will come into effect from January 1.

Until now, dope tests have been conducted only in ICC events such as the World Cup. The sport's governing body began testing at its events in 2002 and became a WADA signatory two years ago.

"Critically, it also means that international cricketers must be available for testing at any time, any day of the year, whether it is at ICC events, bilateral series or even out of competition," the ICC said in a statement.

All full ICC members and the top six associates have already agreed to have WADA-compliant codes by July 1.

The ICC chief executive Haroon Lorgat was confident the code would help tighten anti-doping in the sport although cricket is not considered by most observers to have a major drugs problem.

"This code means it has just become even harder for drug cheats to get away with doping practices and it is part of our continued battle to ensure fair competition for all," he said.
