Halladay died in November when his two-seater ICON A5 amphibious plane nose dived into shallow water off New Port Richey, Florida, which is near Tampa. His blood-alcohol content level was 0.01, according to the toxicology results in the report released by the Pinellas-Pasco Medical Examiner's Office.
There were reports right before the crash that he was flying the plane erratically before he crashed.
The report noted that the morphine found in his system could have been caused by using heroin, but TMZ claims to have sources that say Halladay was never known for using the addictive drug. The plane was equipped with a parachute but it wasn't deployed, and Halladay's body was found with the plane. One source familiar with the autopsy tells us he results are consistent with someone who uses Rx medication.
The FDA said that more than 50 ng/nl of the drug used to treat insomnia, zolpidem (Ambien), can impair "driving to a degree that increases the risk of a motor vehicle accident".
Several nearby boaters confirmed TMZ's report that the pitcher's plane was "dramatically increasing and decreasing in elevation".
Halladay owned the plane, which could hold two people.
He was a member of the Philadelphia Phillies' National League East-winning teams in 2010 and 2011, throwing a no-hitter in the 2010 playoffs against the Cincinnati Reds.
Halladay, 40, was a two-time Cy Young Award victor (2003, 2010) as a member of the Toronto Blue Jays and Philadelphia Phillies.
