About

Few studies have evaluated, in patients with symptomatology the impact of cannabis use on the duration of hospitalization and on short- and medium-term developments. The objective of this study will be to assess the impact of cannabis on the duration, the hospitalization and the short- and medium-term evolution of patients with psychotic symptoms and cannabis use. We hypothesize that these patients (in comparison with patients with psychotic symptomatology and not using cannabis) would be hospitalized more long, exposed to a higher risk of resistance to the usual therapeutics, would have a lack of therapeutic alliance and insight, relapses and hospitalizations more frequent, more marked negative symptoms and lower quality remission. They would also be more prone to impulsive and aggressive behaviour.

Full description

Several studies have reported that cannabis use worsen the prognosis of psychiatric pathologies in general and psychotic in particular.

Few or no studies have evaluated the impact of cannabis consumption on patients with psychotic symptoms during their hospitalization (duration, type of hospitalization, quality of relationship with staff hospital), and on the short-term prognosis.

The objective of this study will be to assess the impact of cannabis on the duration of the hospitalization and the short- and medium-term evolution of patients with a psychotic symptomatology and cannabis use. Making the hypothesis that these patients (compared to patients with symptomatology psychotic and not using cannabis) would be hospitalized longer, exposed at a higher risk of resistance to the usual therapies, to have a lack of alliance therapeutic and insight, relapses and more frequent hospitalizations and symptoms.

They would also be more likely to have lower quality. They would also be more likely to be impulsive, and have aggressive behaviours.
