An autopsy conducted on Roy Halladay following a November 7th plane crash in the Gulf of Mexico showed a potentially lethal mix of drugs including Morphine, amphetamines and Ambien in his system.
Halladay’s toxicology results showed a potentially fatal amount of amphetamines in his system at the time of the crash. According to Forbes Magazine, Halladay’s level of amphetamines measured 1,800 nanograms per milliliter (ng/ml) in his system. A mix of as much as 500 ng/ml can cause death, according to the article. Halladay also had 72 ng/ml of Ambien – generic name Zolpidem – in his system at the time of the crash, more than enough to have impaired his ability to fly his experimental aircraft.
Dr. Michael Garber, a former medical officer for the National Transportation Safety Board, told Forbes that the level of amphetamine in Halladay’s system is consistent with either an overdose or an amphetamine addiction.
In addition to the amphetamines and Ambien, Halladay also had morphine in his system and he registered a blood alcohol level of 0.01, showing that he had also consumed alcohol.
Officially, the cause of Halladay’s death is listed as blunt force trauma, with drowning being a contributing factor.
