Respondents were first asked, Have you smoked at least 100 cigarettes in your entire life? If a respondent answered yes, he or she was then asked, Do you now smoke cigarettes every day, some days or not at all? We used the responses to these two questions to classify respondents into three groups: nonsmokers (those who answer no to the first question or not at all to the second question), nondaily current smokers (those who answer some days to the second question), and daily current smokers (those who answer every day to the second question)
The authors hoped to test four hypotheses: That an excess of tobacco use is already present in people presenting with their first episode of psychosis That daily tobacco use is associated with an increased risk of subsequent psychotic disorder That daily tobacco use is associated with an earlier age at onset of psychotic illness That an earlier age at initiation of smoking is associated with an increased risk of psychotic disorder The authors followed MOOSE and PRISMA guidelines for the conduct and reporting of systematic reviews and meta-analyses, and searched Embase, Medline and PsycINFO for relevant studies
