U.S. Navy Doctor's Drug Study Under Scrutiny

A U.S. Navy doctor faces scrutiny for a drug study involving military members wounded in combat. The federal government has expressed concern over a study conducted by Dr. Michael Hoffer while on deployment in Iraq. Hoffer, a captain the Naval Medical Corps and a well-respected doctor at the Naval Medical Center in Balboa Park, conducted a study of wounded troops suffering from mild forms of traumatic brain injury. According to the Department of Defense, in a test involving 80 troops, Hoffer gave half of the troops a placebo and the other half an antioxidant called NEC -- a drug he reportedly holds two patents for.
