DRAMATIC audio of an emergency call that allegedly captures the moment when Ben Cousins sought help after a five-day cocaine binge has been aired on Melbourne television.

Meanwhile, the Police Association wants the Office of Police Integrity to investigate the role Chief Commissioner Christine Nixon played in Collingwood's decision to pull out of the race to sign Cousins.

It is believed Ms Nixon spoke to Collingwood about Cousins and the Police Association wants Ms Nixon to tell the public what was said.

The Police Association believes it would be bordering on unethical for any senior constable to have such a private discussion and Ms Nixon should reveal what was said or face an inquiry from the OPI.

On the Nine Network an audio has been aired of a woman making a phone call to paramedics in California, saying: "He's conscious, but he's losing his mind." 

The audio is from California late last year, while the fallen AFL star was in the United States for drug rehabilitation.

In excerpts of the call, a woman requests help for a drug-affected male colleague, she calls him "Ben" and tells the operator he is losing his mind.

The Nine Network said Cousins' friend Susie Ela made the call late last year while he was with her in California.

"A friend of mine has been using drugs and he's just losing his mind right now," the woman says in the phone call.

"He's conscious, but he's losing his mind.

"Do you want paramedics - paramedics, Ben? ... yes, paramedics."

Asked what sort of drugs her friend had been using, the woman replies: "cocaine"

The woman is asked whether the subject had been drinking or using other drugs.

When the woman relays the question, a male voice in the background answers "cocaine for five days".

Cousin's manager Ricky Nixon says the former player has been exposed to an unnecessary level of scrutiny in his bid to return to the AFL.

Nixon has responded to reports that Collingwood used a private investigator and discussed his client with Victoria Police, saying he was sick of the attention on Cousins.

"As I said to Collingwood a week ago, if you want to send private investigators to Perth, buzzing around asking nobodies about how Ben Cousins is going, you can just come over to my office and I'll tell you exactly how he's going," Nixon said.

"My vested interest is to tell the truth and give the picture exactly as it is, warts and all — not get the bull---- that's coming out of the Collingwood Football Club," Nixon told radio station SEN yesterday.

"I don't have a problem with due diligence, but I just wonder where it starts and stops."

Also on Friday, it was revealed that Collingwood officials are no longer interested in recruiting Cousins.

St Kilda is considered the front-runner to recruit Cousins, provided he is allowed to play again.

The AFL Commissions will decide on November 17 whether to re-register the Brownlow Medallist and former West Coast captain.

The league suspended him late last year for bringing the game into disrepute.
