Osbourne has misused alcohol and other drugs for most of his adult life. He admitted to "Sounds" in 1978, "I get high, I get fucked up ... what the hell's wrong with getting fucked up? There must be something wrong with the system if so many people have to get fucked up ... I never take dope or anything before I go on stage. I'll smoke a joint or whatever afterwards." Black Sabbath bandmate Tony Iommi said that while all the band were involved with alcohol and other drugs to various degrees in the 1970s, Osbourne had the unhealthiest lifestyle of them all. Despite this, said Iommi, he was typically the only one left standing when the others were "out for the count". Longtime guitarist Zakk Wylde has attributed Osbourne's longevity in spite of decades of substance misuse to "a very special kind of fortitude that's bigger than King Kong and Godzilla combined... seriously, he's hard as nails, man!"
