Olympic Pistol Shooter Used Anti-Trembling Drug to Steady His Hands

In the first major doping scandal of the Beijing Olympics, a North Korean pistol shooter has been stripped of his silver and bronze medals after testing positive for the drug propranolol. The drug, which belongs to a class called beta-blockers, would not be considered a performance-enhancing drug in most sports; it works by blocking the action of adrenaline, and therefore lowers blood pressure and heart rate.
