Based on the autopsy, list the contributing factors to Farley's death in bullet format.
On December 18, 1997, Farley was found dead by his younger brother John in his apartment in the John Hancock Center in Chicago. He was 33 years old. An autopsy revealed that Farley had died of an overdose of a combination of cocaine and morphine, commonly known as a "speedball". Advanced atherosclerosis was cited as a "significant contributing factor."

A private funeral was held for Farley on December 23, 1997, at Our Lady Queen of Peace Catholic Church in his hometown of Madison, Wisconsin. Over 500 people attended his funeral, including many comedians who had worked with him on Saturday Night Live and on film, such as Dan Aykroyd, Adam Sandler, Chris Rock, Rob Schneider, Lorne Michaels, Al Franken, John Goodman, Bob Odenkirk, Tim Meadows, Robert Smigel, George Wendt and Phil Hartman. Notably absent was Farley's best friend David Spade. Spade's non-appearance fueled speculation that there was some falling out with Farley prior to his death. However, years later Spade denied any ill will between him and his comedic partner, admitting that his absence from the funeral was because he would have found it too emotionally difficult. Farley's remains were interred at Resurrection Cemetery in Madison.
