One of Australias top cricketers has been officially warned by the Cricket Australia (CA) after he admitted to being a part of social circles that were involved in cocaine. According to reports, the player, who hasnt been named, did not test positive for the drug, and the CA didnt take any action against him. The player was counselled after the incident, which transpired last year and alcohol was also involved. It is believed the player admitted his involvement after he was confronted with the drug allegations, but since his counselling, there has been no substance issues. It is understood that CA acted on the allegations after the player''s social actions set off alarm bells, and the governing body refused to make any comment on the issue. We are not in a position to comment - our principle is confidentiality, News.com.au quoted a CA spokesperson, as saying to an Australian paper. The first response to a positive test, which we haven''t had, would be in theory to work with the player in a confidential, professional and appropriate and medically focused manner, the spokesperson added.u00a0 No current Australian players have tested positive to drugs.u00a0But in 2003, Shane Warne was sent home from the World Cup after testing positive for a banned diuretic.u00a0 Although Warne claimed he didn't know Moduretic (the prescription drug) was illegal, he was found guilty of breaching the drug code and was banned for one year.u00a0 In 2006, spinner Jason Krejza tested positive to cocaine after complaining his drink was spiked.
