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.
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.

RECRUITINGPANSS: Positive and Negative Syndrom Scale
This scale permit to assess the severity of schizophrenia.Positive Scale, Negative Scale, and General Psychopathology Scale. Each subscale is rated with 1 to 7 points ranging from absent to extreme. The range for the Positive and Negative Scales is 7-49, and the range for the General Psychopathology Scale is 16-112. The total PANSS score is simply the sum of the sub scales.
Time frame: AT the beginning of the study, before any procedure, (T1)

MCQ-SF :Marijuana Craving Questionnaire- Short Form
The scale permit to determine the marijuana craving. The subscales exhibited low to moderate, positive intercorrelations and were significantly correlated with marijuana use history and a wide range of single-item measures of craving. Conclusions. Findings suggested that four specific constructs characterize craving for marijuana: (1) compulsivity, an inability to control marijuana use; (2) emotionality, use of marijuana in anticipation of relief from withdrawal or negative mood; (3) expectancy, anticipation of positive outcomes from smoking marijuana; and (4) purposefulness, intention and planning to use marijuana for positive outcomes.

CGI: Clinical Global Impression
It is used with all patients, allowing the evaluation of the improvement of assessing the severity and change of the overall clinical condition. The clinical global impression - severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. 1. Normal, not at all ill 2. Borderline mentally ill 3. Mildly ill 4. Moderately ill 5. Markedly ill 6. Severely ill 7. Among the most extremely ill patients Improvement scale The clinical global impression - improvement scale (CGI-I) is a 7-point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention. 1. Very much improved 2. Much improved 3. Minimally improved 4. No change 5. Minimally worse 6. Much worse 7. Very much worse

YMRS: Young Mania Rating Scale
The YMRS is a scale of 11 questions to assess the severity of symptoms maniacs. It is considered the gold standard of scales evaluating mania. This instrument is widely used both in the clinic and in research. It is appropriate both to assess the initial severity of manic symptoms, and the response to treatment in patients with bipolar disorder type I and II. Each item of YMRS given a severity rating. There are four items that are graded on a 0 to 8 scale (irritability, speech, thought content, and disruptive/aggressive behavior), while the remaining seven items are graded on a 0 to 4 scale. There are well described anchor points for each grade of severity.
