Wade Goodwyn reports from Dallas, Texas on a number of Gulf War veterans suffering from debilitating illnesses. Doctors at the Environmental Health Center say the vets developed a severe allergic reaction to the chemicals and oil smoke they were exposed to in the Gulf War. For some vets, the symptoms, also known as Multiple Chemical Sensitivity, have carried over to civilian life. The Veterans’ Administration refuses to acknowledge the cause of the illnesses or the Health Center’s unconventional treatments.
