Pro tip: drugs are not a long term, sustainable source of creative energy. They have, in fact, derailed many a career prematurely, occasionally in deadly ways. You don't need to be told this; you know it. It's always been true. Before he died prematurely, after years of drug abuse, Charlie Parker—the alto sax-playing genius of bebop—said exactly this: "Any musician who says he is playing better either on tea, the needle, or when he is juiced, is a plain, straight liar...I may have thought I was playing better, but listening to some of the records now, I know I wasn't."
