I am working on a research paper about heroin culture in America. I have located some sources, but I am interested in finding as many as possible. So far I plan on using Burroughs' "Junkie," a book called "Waiting on the Man," and Jill Jones' Hep-Cats, Narcs, and Pipe Dreams: A History of America's Romance with illegal drugs. The paper is for a U.S. history course, and I am dealing specifically with the years from 1887 forward. If anyone knows of any sources (books, articles, websites) that might help, please tell me.
