The US Defence Department forced all "war on terror" detainees at the Guantanamo Bay prison to take a high dosage of a controversial antimalarial drug, mefloquine, an act that an Army public health physician called "pharmacologic waterboarding."
The US military administered the drug despite Pentagon knowledge that mefloquine caused severe neuropsychiatric side effects, including suicidal thoughts, hallucinations and anxiety. The drug was used on the prisoners whether they had malaria or not.
The revelation, which has not been previously reported, was buried in documents publicly released by the Defence Department (DoD) two years ago as part of the government's investigation into the June 2006 deaths of three Guantanamo detainees.
Army Staff Sgt. Joe Hickman, who was stationed at Guantanamo at the time of the suicides in 2006, and has presented evidence that demonstrates the three detainees could not have died by hanging themselves, noticed in the detainees' medical files that they were given mefloquine. Hickman has been investigating the circumstances behind the detainees' deaths for nearly four years.
