"Nicotine addiction is the number one cause of premature illness and death in the United States, and most of that morbidity and mortality is concentrated in people with mental illness."

In a report published recently in the journal Addiction Biology, the research team lead by Dr. Chambers reported the results of experiments using an established animal model of schizophrenia in which rats display a neuropsychiatric syndrome that closely resembles the disease.

Both the schizophrenia-model rats and normal rats were given access to intravenous self-administration of nicotine.

"The mentally ill rats acquired nicotine use faster and consumed more nicotine," Dr. Chambers said. "Then when we cut them off from access to nicotine, they worked much harder to restore access to nicotine than did the normal 'control' rats."
