No drugs in Cho's system

The anti-psychiatry crowd tried to use the Virginia Tech case to paint the frightening image that psychiatric medications caused Seung-Hui Cho to go on a murderous rampage. In an unsigned letter, one group issued a demand for the toxicology report under the Virginia Freedom of Information Act, threatening legal action.

Last week, the results of toxicology tests were released. But, the fearmongers won’t be pleased. The state medical examiner's office found no trace of prescription drugs or toxic substances in Cho's body.

In this day and age, it is hard to believe that there are still people who deny the existence of severe mental illnesses and point to everything but untreated psychotic symptoms as the cause of harmful behaviors. But, the research shows that schizophrenia and bipolar disorder are diseases of the brain. And as most people suspected, it was Cho’s untreated symptoms that caused so much devastation.
