By integrating ecological momentary assessment (EMA) with cognitive tasks such as reality monitoring, the research seeks to clarify how cannabis use influences symptom severity and cognitive functioning in individuals with schizophrenia. Gaining insight into these relationships may contribute to the development of more effective management strategies and ultimately improve outcomes for patients living with schizophrenia.",[55],"Schizophrenia",[57,58,59,60],"cannabis","schizophrenia","EMA","reality monitoring","NOT_YET_RECRUITING","2026-03-13",{"date":64,"type":65},"2026-03-16","ACTUAL",{"date":67,"type":48},"2026-06-01",{"date":69,"type":48},"2028-12-31",{"name":5,"class":6}]
