Clinical features of schizophrenia and cannabis-induced psychosis (CIP) share many overlapping characteristics. We present a case of Cannabis Dependence Syndrome, whose first presentation was with first-rank symptoms of schizophrenia in the form of thought insertion, withdrawal and delusion of control.
