Pitchman Billy Mays died of a heart attack in his sleep in June. His autopsy now shows that cocaine contributed to the death of the TV personality, the Associated Press reports. A release from the medical examiner's office Friday said Mays had last used the drug days before his death.

Other narcotics were found in May's system, though the St. Petersburg Times reports that Mays was taking hydrocodone, oxycodone and tramadol by prescription for hip pain. The report said that although Mays died from heart disease, cocaine use was a contributing cause of death.

"Cocaine can raise the arterial blood pressure, directly cause thickening of the wall of the left ventricle of the heart, and accelerate the formation of atherosclerosis in the coronary arteries," the Hillsborough County medical examiner's press release stated.
