In studies conducted at the National Institute of Mental Health, Yale University and other sites, test subjects took small doses of ketamine, also known as "Special K" or the "date rape drug." Scientists conducting the study said volunteers were carefully screened for mental illness and signed consent forms that warned of side effects such as hallucinations and mood changes. But critics said the drug's risks are not fully known and questioned the ethics of inducing psychotic behavior in healthy people. "The idea of inducing psychosis, in psychology or psychiatry, is the worst thing that can happen," Carl Tishler, an adjunct professor at Ohio State University, said Thursday. "If you are a cardiologist, do you induce a heart attack in someone to see what it's like so you can study it?" Ketamine is a trendy designer drug used mainly by young people who pay $20 to $40 per dose. Nationwide, the drug has been connected to at least one death of a teenager who mixed it with heroin; numerous sexual assaults; and thefts from veterinarians' offices and hospitals. Often used as a surgical anesthetic for people and animals, the Food and Drug Administration-approved drug can cause mild hallucinations, confusion and fear with regular use. Severe hallucinations are possible with large doses. The Boston Globe reported Thursday that healthy subjects run the risk of flashbacks months after using ketamine. "If this is what they do to normal (people), God help us with the cognitively impaired," Adil Shamoo, a University of Maryland bioethicist, told the newspaper. But scientists say ketamine can give researchers insight into the nature of hallucinations and mood disorders, helping to unlock the mysteries of mental illness. The experiments began in the early 1990s and ended more than a year ago. They were designed to provoke symptoms of schizophrenia in healthy people during a one-time exposure, said Dr. Trey Sunderland, chairman of NIMH's review board. - --- MAP posted-by: Patrick Henry
