The Long addiction of Michael Jackson to the anaesthetic propofol drug.

Michael Jackson propofol.It has been documented many times how the King of Pop died from the drug Propofol wrongly administered to him by his private doctor,Dr Conrad Munray.But now it has emerged that the pop star had been using the drug at least a decade before he met his death through the same drug.

Michael Jackson requested the anaesthetic propofol to help him sleep at least a decade before he died from an overdose of the drug, a doctor told a court.

Dr Christine Quinn said Jackson summoned her to a Beverly Hills hotel in 1998 or 1999 and

asked her to give him propofol.

The request came after she met the entertainer while he was undergoing dental procedures. She said she refused the request and told Jackson it wasn't appropriate to use anesthesia as a sleep aid.

"I told him that the sleep you get with anesthesia is not real sleep, not restful sleep," Quinn said.

Jackson responded by saying his time under anaesthesia was the best sleep he had ever had, she testified.

Jackson died in 2009 from an overdose of propofol that was administered in the singer's bedroom by Conrad Murray, who was later convicted of involuntary manslaughter.

Quinn was testifying for the defense in a negligent hiring lawsuit filed by Jackson's mother against AEG Live LLC, the promoters of the singer's ill-fated comeback concerts. AEG denies it hired Murray.

Quinn said she gave Jackson anesthesia for procedures done after the meeting at the hotel. He never asked for propofol after the meeting or requested that he be kept under for longer than was medically necessary, she said.

AEG Live has called a number of Jackson's former doctors to testify.

One expert hired by the company, Dr Petros Levounis, told jurors on Tuesday that Jackson exhibited signs that he was doctor shopping and trying to find medical practitioners who would give him opioid medications.

Attorneys for Jackson's mother have acknowledged the singer struggled with prescription medications but said he generally received anaesthesia and medications during medical and dental procedures.

They rejected the characterisation of Jackson as an addict.
