Smoking is bad for you blah blah we know. But you couldn't really tell that to the 80% of American schizophrenic patients who smoke. The jury is still out on why that number's so high, but could some form of treatment come out of this?
That so many schizophrenics smoke was actually established in a study published in 2006, but the figure has held up since then, even in the face of stiffer tobacco regulations and society in general backing away from it. There are a number of hypotheses that try to explain the link—personality, socioeconomic situation, etc.—but Mark Stewart for the University of Michigan Risk Science Center writes that the patients may be smoking as a means of self-medication.
