The government has launched an investigation to determine how actor Heath Ledger was able to obtain so many prescription drugs.
The government is investigating whether a licensed doctor stepped outside of the normal standard of practice to supply drugs to an addict for recreational use rather than for therapeutic use.
When dealing with the very rich, certain money hungry doctors forget their oath to first, do no harm to their patients.
According to Dr. Michael Hunter, a prominent forensic pathologist, the level of tranquilizers, pain killers and sleeping pills in Ledger's system were intended to obtain an intoxicant effect - not for therapeutic use.
Dr. Hunter tells PEOPLE that the combination of the powerful drugs most likely caused "poly-drug intoxication" which led to respiratory arrest. "His breathing probably got slower and slower until it stopped all together," he said. (source)
