Steve Jobs discovered one definite way to "think different." The mega-mind behind Apple took LSD some 15 times, and it was a "life-changing experience," Jobs revealed on a 1988 security clearance application he filled out for the Department of Defense. "It was a positive life changing experience for me, and I am glad I went through that experience," Jobs said of his several trips from 1972-74. "I would ingest the LSD on a sugar cube or in a hard form of gelatin," he said on the application obtained by Wired. "I would usually take the LSD when I was by myself."
Jobs also smoked pot or hash, or ate it cooked into brownies, once or twice a week between 1973 and 1977, he revealed. "The best way I would describe the effect of the marijuana and the hashish is that it would make me relaxed and creative," he said. Jobs' security clearance was required because intelligence agencies were using Pixar's image computer for configuring information gleaned from reconnaissance flights and satellites, according to Walter Isaacson’s biography of Jobs.
