London, July 3 Cops have reportedly found a horde of 20 different drugs at late singer Michael Jackson's home, of which ten are potentially lethal painkillers and anaesthetics.

There were anti-anxiety pills, including Valium, Methadone, used to wean junkies off heroin, Demerol, a pain reliever, anaesthetic Propofol, dubbed "the Milk of Amnesia", Fentanyl, a powerful pain reliever given to terminal cancer patients and Oxycontin, a painkiller similar to morphine but branded "Hillbilly Heroin".

"The Jackson mansion was more like a drug store than someone's home," the Sun quoted a source close to the probe as saying.

Some of the medications bore labels showing that they had been prescribed to Jacko, while rest of them were labelled with other names - and some were not labelled at all.

The King of Pop is believed to have used aliases to obtain his prescriptions.

"Powerful narcotic painkillers of all kinds were found. There was no reasonable excuse for them all being there. Using more than one of this type of drug can be potentially fatal," said the source.

"But there were ten in the house - it's unbelievable.

"Police want to know whether the other people named on the medicine labels really needed the drugs prescribed to them and will be speaking to the doctors involved.

"The drugs found remain at the very heart of the investigation into the death of Michael Jackson," the source added. (ANI)
