Primary Outcome Measures:
  • Clinical assessment with several psychopathological scores for self-assessment and peer evaluation (BPRS, PANSS, SIPS, CGI, MADRS, HAM-A, SCL-90-R) [ Time Frame: Seven days ]
  • Laboratory assessment (routine testing, "-omics", genetic analyses, endocannabinoid levels) [ Time Frame: Seven days ]
  • Diagnostics of the cerebrospinal fluid [ Time Frame: Seven days ]
  • fMRI scan of the brain [ Time Frame: Seven days ]

Secondary Outcome Measures:
  • Regular evaluating of the subject's condition and ability to continue the study by CGI [ Time Frame: Seven days ]
  • Regular laboratory testing and ECG [ Time Frame: Seven days ]
