I'm not sure how well it's being reported, but there have been a few disqualifications for doping at the Olympics. The always above-board DPRK lost both a bronze and silver medal after testing positive:
BEIJING - Kim Jong-su of the Democratic People's Republic of Korea (DPRK) has tested positive for doping at the ongoing Beijing Olympic Games, the International Olympic Committee (IOC) said here on Friday at a press conference.
What struck me as odd were the events he won medals in:
Kim took a bronze in men's 10-meter air pistol on August 9 and won a silver in the men's 50-meter pistol final on August 12.
So there are drugs which make you shoot better? Actually, there are. He tested positive for propranolol, a drug prescribed for hypertension and migraines in children. It helps reduce trembling.
I must be missing the reason athletes take these drugs, knowing they will be tested.
