Aleister Crowley&#39;s&nbsp;<i>Diary of a Drug Fiend</i>&nbsp;is one of the earliest and greatest of narcotic memoirs, and deserves to be mentioned alongside such addiction classics as&nbsp;<i>Confessions of an English Opium Eater, Naked Lunch, Fear and Loathing In Las Vegas</i>&nbsp;and&nbsp;<i>Trainspotting</i>.
