THE troubled entertainer today admitted cocaine possession when a court heard he concealed a white substance in his mouth during a strip search by police.
His court appearance came after an early-morning car collision last month.
He admitted possessing cocaine during an appearance at Ealing Magistrates' Court today and was fined over €900 for the offence.
Barrymore, real name Michael Parker, appeared shaky as he entered the west London court dressed in a dark suit, white shirt and maroon tie.
Police officerstestified they had approached him after their attention was drawn to a vehicle parked on the side of the road which had accident damage.
Asked who had been driving the vehicle, he replied "I am not answering you", the court heard.
Then, launching into an angry tirade to the officers, he went on: "Don't you think I've had enough f****** s*** from you lot over the years? I know the law."
Arrested and taken to a police custody suite, he tried to conceal what looked like a white substance in his mouth, the arresting officer testified.
"He refused to spit it out, was strip-searched and a rock of cocaine was found in his pocket," she told the court.
A drug test found him positive for the class A drug.
Barrymore's lawyer, Richard Gowthorpe, reminded the court that the quantity of the drug involved had been described as "a very small amount" and that the entertainer had apologised to the police for his behaviour.
Barrymore had urged his lawyer to point out that the evening in question had been "exceptional" and that "there was an exceptional set of circumstances" at the time, Mr Gowthorpe added.
"This behaviour is wholly out of character. This is not part of a general lifestyle that Mr Parker is living.
"He's addressing the problem, he's addressing the temptation and there's no present drug use."
The court heard that Barrymore had been seeing a drug worker since the night of the incident and was making "very good progress"
Drug worker Andrew De Cruze said: "Steps have been put in place to support Mr Parker in any way we can.
"He's undergoing cognitive behavioural therapy. It's something Mr Parker has found very helpful and is willing to engage further in that process."
Barrymore was also addressing his alcohol use and had been attending Alcoholics Anonymous meetings, Mr De Cruze told the court.
"I would say Mr Parker is doing everything he can do address the issues," he added.
Earlier, the hearing was briefly adjourned after Barrymore's lawyer objected to his address being read out in court, citing "intense attention" surrounding his client.
Magistrates declined permission for the address to be withheld however, and Mr Gowthorpe gave it as Fleet Street in central London.
