However they revealed that two members of the Maroons squad had been reprimanded for being out on the drink after curfew early in the team's match preparations.

Queensland coach Mal Meninga and team manager Steve Walters met with QRL managing director Ross Livermore at QRL headquarters in Brisbane on Tuesday to review the Origin series.

There had been allegations that some players had mixed the prescription sleeping drug Stilnox with the high-energy drink Red Bull, providing similar effects to cocaine and ecstasy without the danger of testing positive to a banned drug.

However Livermore said several players questioned about the claims made initially in The Australian newspaper last Friday had denied any knowledge of the use of drugs.

Queensland team captain Darren Lockyer attended the Origin review and also gave his version of events.

’’Our investigations haven't found any evidence to substantiate the allegations," said Livermore.

Livermore said two players had been found to have broken team curfew early on in the camp and had since been reprimanded for their actions.

Livermore refused to name the players or say if their State of Origin careers had been jeopardised.

A stern-faced Meninga left the meeting without commenting to reporters.

He had earlier described the reports of drug use and a boozy camp as ’’scurrilous rubbish".

Livermore said unless some further evidence was produced or someone came forward with some proof, the investigation would probably not go any further.
