New evidence has emerged that all Guantanamo Bay prisoners, including David Hicks, were drugged involuntarily with a substance that has a long history as a truth serum. Recently declassified US documents revealing medical procedures have shown that scopolamine was administered to all detainees taken to the Cuban detention centre. Documents... reveal that the rationale for the drug's use on all detainees was to prevent motion sickness. However, US military experts have said that scopolamine is not recommended for motion sickness because of its severe side effects. The Sun-Herald revealed this month that Mr Hicks and other prisoners were drugged against their will with unknown substances and that detainees' medical records were incomplete, with the names and dosages of drugs removed.
