Jackson died of lethal levels of potent drugs

The leaked toxicology report of Michael Jackson claims that the pop star had lethal levels of potent painkillers and drugs in his body at the time of his death, triggering suspicion that it may be a case of homicide.

Jackson was on a diet of deadly cocktail potent enough to have killed a normal person instantly but his body had developed a tolerance due to the longtime use of huge doses, the British newspaper Sun claimed quoting the findings of his preliminary toxicology reports.

Apart from high levels of Demerol, a strong painkiller and heroin substitute Methadone, Jackson's blood tests found high doses of antianxiety drug Xanax, according to the leaked toxicology report submitted to the Los Angeles county coroner's office, the paper said.

Lower levels of powerful anaesthetic drug Propofol was also present in Jackson's body. The medicine is used forsurgical operations but according to Jackson's close aides, the pop star, who suffered from insomnia, used the medicine as a sleeping pill.

Another medicine, Dilaudid, which is normally used to numb post-surgery pain was also found in Jackson's body.

Jackson died after collapsing on June 25 just weeks before making his comeback in London and reports have linked his sudden death to the long abuse of prescription drugs.
