According to the statement released to the Associated Press by the Hillsborough County medical examiner, the autopsy concluded that cocaine use caused or contributed to the development of Billy Mays heart disease, and thereby contributed to his death.
The autopsy showed that Billy Mays used cocaine a few days before his death, but was not under the influence of the drug when he died. The autopsy could not determine the frequency of cocaine use. Therapeutic amounts of painkillers hydrocodone, oxycodone and tramadol, as well as anti-anxiety drugs alprazolam and diazepam were also found in his system.
