Note: The data for the number of drug tests conducted and the number of doping cases recorded from 1968-2004 were extracted from the International Olympic Committee's (IOC's) Jan. 2010 report "Factsheet: The Fight Against Doping and Promotion of Athletes' Health." (130 KB) The number of drug tests conducted and number of positive tests recorded for 2008 was obtained from the Nov. 8, 2008 New York Times article "Awaiting Test Results," by the Associated Press (AP). ProCon.org calculated the percentage of positive tests and the totals. *The 20 positive results include 14 people and six horse-doping cases. **The IOC's report states that "the cases recorded covered not only adverse analytical findings reported by the laboratory, but also violations of the anti-doping rules, such as non-arrival within the set deadline for the test, providing a urine sample that did not conform to the established procedures, and refusal to comply with the procedures or to deliver urine." The 1992 Albertville Olympic Games were the last Winter Games held in the same year as the Summer Olympic Games.

"With a record 24 athletes ousted for drug-related violations, perhaps the biggest upset of the Olympics was no U.S. team member flunked a doping test...

The record number could increase after urine samples from the final weekend competitions are processed. If drug-testing technology continues to improve, it's possible stored urine samples could be tested later, and reveal more cheaters...

The previous Summer Olympics record for athletes banned because of doping violations was 12, at Los Angeles in 1984...

Weightlifters, as usual, were easily the biggest offenders, with 12 banned from competition in Athens.

Coming into these Games...weightlifting had 24 of the 57 failed tests since testing began in 1968.

Hungary had the most offenders, with five.

Russia had its most drug-tainted Olympics, with three violators. Before these Games -- and including the Soviet Union era -- only one Russian had tested positive at a Summer Olympics. Among the banned Russians was the women's shot put champion, Irina Korzhanenko.

Bulgaria, the all-time Summer Olympics leader with eight doping violations, had none in Athens.

The last time U.S. athletes tested positive at a Summer Olympics was at Barcelona, in 1992, when shot putter Bonnie Dasse and hammer thrower Jud Logan were banned."

"The Olympic equestrian events...reeled from success to scandal as doping again cast doubt on the future of elite horse sports in the Games...

The suspension of four riders from Thursday's grand finale show jumping contest, after their horses tested positive for a banned substance, pointed to the possibility of systemic doping in the sport...

The incident resurrected the spectre of Athens in 2004 and Sydney in 2000, when show jumping team and individual medals were re-allocated due to doping...

The horses in question were among 60 the FEI said were tested - 20 each from eventing, dressage and jumping of a total of 218. Samples were analysed at HKJC labs, considered among the world's best.

A club source wondered if the HKJC's [Hong Kong Jockey Club's] ability to detect the agent had been underestimated as no positive tests for capsaicin have been returned before now though it has been testable for two years.

The substance is a by-product of chilli and its use points not only to widespread doping but cruelty in the training regimes for show jumpers."
