Is smoking tobacco associated with psychotic experiences across racial categories in the United States? Findings from the Collaborative Psychiatric Epidemiological Surveys.

Smoking tobacco has been associated with psychosis, though research has yet to fully examine the extent to which this association reaches into the sub-threshold range of the psychosis continuum within the US, and whether this association persists after accounting for co-occurring disorders. We analyzed data from three large racially-diverse surveys of the US population and found that current smokers were more likely to report a lifetime psychotic experience when compared with never smokers after adjusting for socio-demographics. But after controlling for anxiety, mood, and substance use disorders, these effects only remained strong and statistically significant for Asian-Americans.
