Drugs charges against State of Origin star Greg Bird and now-retired Gold Coast Titans teammate Ashley Harrison have been thrown out of court.

Bird was caught up in an alleged cocaine syndicate dismantled by Queensland's Crime and Corruption Commission last year, with prosecutors alleging he used coded conversations with accused kingpin John Touma to arrange a supply of cocaine for his buck's party.

"At the end of the day there is a lot of speculation, there is suspicion, but there is lacking proof of Bird being involved in a conspiracy," Magistrate Chris Callaghan told the court on Thursday, before declaring the charges against Harrison were even weaker.

Outside court, a relieved Bird thanked his legal team.
