Saids and the World Anti-Doping Agency define substances of abuse as those “frequently abused in society outside of the context of sport”.

“The player accepted responsibility for the doping offence and honoured his provisional suspension,” Saids said.

Its statement added that Rabada was offered a chance to undertake a treatment programme, completing two sessions to bring his suspension to an end.

In revealing his suspension, Rabada, who initially said he was leaving the IPL for “personal reasons”, said he was “deeply sorry to all those that I have let down”.

“I will never take the privilege of playing cricket for granted,” he said. “This privilege is much larger than me. It goes beyond my personal aspirations.”

Rabada played twice for Gujarat Titans in this year’s IPL, most recently on 29 March.

He returned to South Africa after being notified of his ban but is now back in India and took part in training on Monday.

“He will take his lessons from this and we’re just looking forward to having him back part of our group, having him back in practice,” said Titans director of cricket Vikram Solanki.

“He’s served his time.”
