Résumé :
FRANÇAIS :
Examen de 5 études longitudinales ayant étudié la relation entre usage de cannabis et expérience consécutive de symptômes psychotiques ayant nécessité une hospitalisation lors de laquelle le diagnostic de schizophrénie a pu être confirmé.
ENGLISH :
Aim : To study the role of cannabis use in the onset of symptoms and disorders in the schizophrenia spectrum. Design : Review of five population-based, longitudinal studies on the relationship between cannabis use and problems ranging from the experience of psychotic symptoms to hospitalization with a confirmed diagnosis of schizophrenia. Several hypotheses are examined that may explain this relationship : (1) self medication ; (2) effects of other drugs ; (3) confounding ; (4) stronger effect in predisposed people, and (5) etiological hypothesis. Findings : Hypotheses 1 and 2 can be dismissed ; hypothesis 3 is still open to debate, and converging evidence is found for hypotheses 4 and 5 - antecedent cannabis use appears to act as a risk factor in the onset of schizophrenia, especially in vulnerable people, but also in people without prior history. Conclusion : There is an intrinsic message here for public health, but how that message is to be translated into action is not immediately clear. (Review' s abstract)
