In his autobiography "I Am Ozzy", Osbourne speaks at length about the sessions: "In spite of all the arsing around, musically those few weeks in Bel Air were the strongest we'd ever been." But he admits, "Eventually we started to wonder where the fuck all the coke was coming from ... that coke was the whitest, purest, strongest stuff you could ever imagine. One sniff, and you were king of the universe." Osbourne also recounts the band's ongoing anxiety over the possibility of being busted, which worsened after they went to the cinema to see "The French Connection" (1971), about undercover New York City cops busting an international heroin-smuggling ring. "By the time the credits rolled," Osbourne recalled, "I was hyperventilating." In 2013, Butler admitted to "Mojo" magazine that heroin, too, had entered the picture: "We sniffed it, we never shot up ... I didn't realize how nuts things had gotten until I went home and the girl I was with didn't recognize me."
