Though an association between tobacco smoking and psychotic illness is well known, reasons for the association are more ambiguous.\u00a0 Recent research has associated smoking tobacco with an increased risk for developing psychosis (Gurillo, Jauhar, Murray, & MacCabe, 2015).\u00a0 The authors reviewed studies that reported rates of smoking in people with psychotic disorders compared with controls.\u00a0 They hypothesized that tobacco use is associated with increased risk of psychotic illness, that smoking is associated with an earlier age of onset of psychotic illness, and an earlier age of smoking is associated with increased risk of psychosis.\u00a0 Overall, though the association between tobacco use has been established, little attention has addressed if tobacco may actually increase the risk of psychosis.<\/p>\n

Gurillo, Jauhar, Murray, and MacCabe\u2019s (2015) analyzed 61 studies composed of 15,000 tobacco users and 273,000 controls.\u00a0 The results indicate that people who suffer from psychosis are three times more likely to smoke.\u00a0 Also, 57% of individuals with first episode psychosis were smokers.\u00a0 The risk of psychotic disorder increased modestly by daily smoking.\u00a0 In short, daily tobacco use was associated with increased risk of psychosis and with an earlier age of onset of psychosis.<\/p>\n

Again, it is difficult to determine the direction of causality; rather an association between tobacco use and psychosis was supported.\u00a0 Also, the authors noted the possibility of publication bias might be present.\u00a0 Even still, the authors caution that smoking should be considered a possible risk factor for developing psychosis, and should not be construed as merely a consequence of the illness.\u00a0 Furthermore, consistent with the dopamine hypothesis, they suggest that nicotine exposure may increase the release of dopamine and cause psychosis to develop.\u00a0 Limitations include, a small number of longitudinal prospective studies and determining the exact consumption of other substances in some of the included studies.\u00a0 Of course the authors suggest more research is needed.\u00a0 Overall, they note that tobacco use may be a modifiable risk factor for psychosis, and every effort should be made to modify smoking habits in this population.<\/p>\n
