Propofol, Lidocaine Found in Michael Jackson's Home

An extremely dangerous, potent drug used for surgical anesthesia was found at Michael Jackson's residence after he died ... and may well what killed him.

According to TMZ, Propofol was confiscated at his home. A source said, "There is no conceivable way this drug can be properly prescribed for home use."

Some facts about this dangerous drug:

• Propofol can only be administered with an IV.
• The drug is used to put people under anesthesia before surgery.
• It is extremely powerful, and only available to medical personnel.
• Propofol burns and the drug Lidocaine is used to reduce the pain associated with the Propofol injection. Lidocaine was found near Jackson's body.
• One of the major side-effects of Propofol can be cardiac arrest if it's taken in combination with narcotic painkillers. However, some sources suggest that Propofol is so powerful it can stop someone's heart on its own.

In the wake of Michael Jackson's death, a registered nurse has come out and said the star begged her for the drug Diprivan - the brand name for Propofol.

She says he needed it for insomnia but she declined to supply it.

Sources say that Propofol is so inappropriate and reckless for home use, if a doctor facilitated it for Michael Jackson and it caused his death, he or she could even be prosecuted for manslaughter under certain circumstances.

This is not to say the icon's personal physician, Dr. Conrad Murray, administered this drug or anything else, only what TMZ's sources say about Propofol.

While a drug overdose has been widely speculated, Michael Jackson's autopsy results list the official cause of death as unknown pending further toxicology testing, which should shed more light on his tragic demise in 4-6 weeks.
