The International Olympic Committee currently lists caffeine as a restricted drug. Urinary levels up to a concentration of12 mg/liter are acceptable, representing casual use. Levels above this are viewed as achieved through a deliberate attempt at doping by the athlete. Approximately 1000mg of caffeine (about 8 cups of coffee) would be required to exceed the current IOC limit, but it is very important to note that people can metabolize caffeine at very different rates. Differences in metabolism, medications, and certain diseases may significantly alter the rate in which caffeine is cleared from the body. Some athletes have come close to flunking the drug test after ingesting only 350mg. It is wise to consider this before using caffeine as an ergogenic aid.
