Mohammed Asif on Monday became the first cricketer to have tested positive twice in dope tests even though cricket is replete with incidents where a number of players have been found guilty of the offence.
The Indian Premier League on Monday confirmed that a Pakistan paceman Asif was the cricketer who tested positive in the random samples during the cash-rich IPL tournament.
Asif, along with Shoaib Akhtar, also had tested positive for banned drug nandrolone in 2006 ahead of the Champions Trophy tournament in India.
Cricket's image took a beating in 2003 when Australian spin wizard Shane Warne was found guilty of using banned diuretics and was subsequently excluded from the World Cup team.
A one-year ban was also imposed on the legendary leg-spinner.
West Indies player David Murray had also conceded that he was taking drugs since 1978. He revealed that he took marijuana before and after the match and even had to go to the jail for the offence.
England all-rounder Ian Botham was also suspended for two months by the ECB for consuming hemp. Botham initially denied taking any drug but according to reports he later accepted his guilt.
