Phencyclidine (PCP) is a known psychotomimetic drug that can induce positive and negative symptoms of schizophrenia, including hallucinations, delusions, and cognitive disturbances. Alcohol and chlordiazepoxide are depressants that can cause sedation and impaired judgment but do not typically produce schizophrenia-like symptoms. Haloperidol is an antipsychotic medication used to treat symptoms of schizophrenia, so it would not typically produce symptoms of the disorder.
