Opium Eating: An Autobiographical Sketch by an Habituate is a book by an anonymous author. It covers the harsh conditions that can come about when opium is used. Excerpt: "The physician gave me a great deal of information, which, taking it simply as a much better knowledge of my condition, rallied and cheered my spirits considerably. In referring to the diarrhœa, he said that it invariably followed; that leaving off the opium unlocked all the secretions, and the diarrhœa was a natural consequence. I was not using much morphia at this time. The quantity was indeed so small that the physician almost ridiculed the idea of my being in the habit at all. I knew better than that, however. He said it was hardly necessary to give anything to check the diarrhœa, in fact, that it was almost useless, and unless it actually became too severe, it was better to let it take its own course; that when it stopped of its own accord I would perceive that I was better. He gave me a few powders to take along, nevertheless, which I did not find it necessary to use."
