Risultato della ricerca: Article

Abstract

Introduction: Cannabis is one of the most common substances used by patients with a first episode of psychosis. The aim of the study was to investigate the most frequent effects of cannabis use, their relationship with psychotic symptoms and characteristics of the consumption.Methods: 116 first episode psychosis were recruited, 50% of which (n=58) used cannabis lifetime. We investigated the characteristics of the consumption and the effects of cannabis using the Cannabis Experience Questionnaire-mv (CEQmv) and the psychotic symptoms using the Positive and Negative Symptoms Scale (PANSS).Results: The effects more often experienced by cannabis users were slowed down thinking and feeling to be able to understand the world better. Feeling fearful was associated with interruption of consumption (U= 287,500, p=0.046). Hearing voices was associated with more than 50 times lifetime cannabis use (U=223,00, p=0.043). In addition, we found correlations between feeling fearful and like going crazy after cannabis use and positive and general PANSS.Conclusions: Those who have experienced more psychotic-like effects of cannabis present stronger positive symptoms. In addition, awareness of negative effects involves the interruption of consumption. These evidences underline the importance of primary and secondary prevention regarding the effects of cannabis use among people at high risk for psychotic disorders.
