Queensland Reds back Karmichael Hunt has been handed a six-week ban and fine of 30,000 Australian dollars by the Australian Rugby Union.
Hunt pleaded guilty to four counts of possession of cocaine on Thursday, fined 2,500 AUD at the Southport Magistrates Court.
"As a result, the Australian Rugby Union (ARU) and Queensland Rugby Union (QRU) today suspended Karmichael Hunt for six weeks and fined him $30,000," an ARU statement read.
Hunt, who will also undergo a drug treatment rehabilitation program, has accepted the penalties.
The code-hopper can return to Super Rugby in round eight, when his Reds face the Melbourne Rebels on April 3.
Hunt, who has been sacked as the team's vice-captain, can train at Ballymore when the Reds are not, but can resume with the squad from March 23.
The 28-year-old apologised and said he wanted to repay the Reds.
"I made a terrible mistake last year and have no one but myself to blame for this situation," Hunt said in the statement.
"I am genuinely sorry for the distress I have caused my family, friends, team-mates, Reds members, sponsors, fans and the wider rugby and sporting community in Queensland and beyond.
"I intend to work through the education and rehabilitation program and will return to the game in a way that sends a clear message to sports fans of all ages that the use of illicit substances has no place in sport.
"I am grateful for the support I have received from Queensland Rugby over the past few weeks and intend to repay their loyalty through my future actions on and off the field."
ARU chief executive Bill Pulver said Hunt had shown remorse and been co-operative.
"We are extremely disappointed in Karmichael’s actions as illicit substances have no place in rugby," he said.
"However we acknowledge that he is sincerely remorseful and has co-operated with the investigation and our integrity enquiries throughout this process.
"Karmichael has also accepted the penalty and consequences of his actions and understands the requirements of a professional athlete and the expectations of our code."
