We hypothesize that acute schizophrenia (AS) and CP can have distinct demographic, premorbid and clinical features.<\/jats:p><jats:p> <jats:bold>Method:<\/jats:bold>\u2002We compared 26 patients with CP to 35 with AS, after their cannabis\u2010consumption status was confirmed by repeated urine screens. Patients with CP were assessed after at least 1\u2003week but not more than 1\u2003month of abstinence. Symptoms were evaluated with the Present State Examination (PSE).<\/jats:p><jats:p> <jats:bold>Results:<\/jats:bold>\u2002In group CP, male gender, expansive mood and ideation, derealization\/depersonalization, visual hallucinations, and disturbances of sensorium were more frequent than in group AS.
