Amid rumors of a drug addiction and a shocking drop in weight, singer Whitney Houston sat down with Diane Sawyer of ABC News at her Atlanta home to confront the charges. Did she smoke crack? "Crack is whack," she said by way of denial. But she did fess up to using drugs, alcohol, cocaine and pills "at times." In February 2012, she died in a tub at the Beverly Hilton Hotel, which an autopsy showed was from the effects of cocaine use and heart disease.
