Cocaine-induced psychosis and PCP-induced psychosis each resemble some symptoms of schizophrenia but differ in their specific features. In a retrospective study of 34 male crack-cocaine-dependent patients without other psychiatric disorders and 16 actively psychotic men with schizophrenia, certain First Rank Schneiderian Symptoms such as thought broadcasting and thought withdrawal were more common in the schizophrenic group. In a separate group of 22 cocaine addicts with past use of both cocaine and PCP, the frequency of these symptoms during intoxication was similar for both drugs.
