"I brought something back from those experiences [with drugs] which made me softer, open to other ideas. And I've learned from listening to other people talk about their experiences, from listening to Bill Hicks or reading Terrence McKenna or Aldous Huxley and Timothy Leary. But there's always some dumb cop out there who says "We don't need another legal drug and there's psychological addiction and blah blah blah.""
