• In the 1904 Olympics, Thomas Hicks (USA) won the marathon at St. Louis and collapsed. It took hours to revive him; he had taken brandy mixed with strychnine to help him win his gold medal.
• The World Weightlifting Championships of 1954 featured the first unconfirmed attempt at doping. Testosterone injections by Soviet Athletes resulted in the Soviets winning the gold medal in most weight classes and breaking several world records.
• In early 1960s Dr. John Ziegler (who was the US Team Coach in the 1954 Soviet-dominated World Weightlifting Championships) administered his weightlifters Dianabol tablets and the US dominated the 1962 World Championships.
• During the 1967 Tour de France, Tom Simpson collapsed during the ascent of the Mont Ventoux. Despite mouth-to-mouth resuscitation and the administration of oxygen, plus a helicopter airlift to a nearby hospital, Simpson died. Two tubes of amphetamines and a further empty tube were found in the rear pocket of his racing jersey.
• A famous case of illicit drug use in a competition was Canadian Ben Johnson's victory in the 100 m at the 1988 Summer Olympics. He subsequently failed the drug test when stanozolol was found in his urine. He later admitted to using the steroid as well as Dianabol, Cypionate, Furazabol, and human growth hormone amongst other things. Johnson was stripped of his gold medal as well as recognition of what had been a world-record performance. Carl Lewis was then promoted one place to take the Olympic gold title. Lewis had also run under the current world record time and was therefore recognized as the new record holder.
• In the 1970s and 1980s, many athletes from a variety of sports (including swimming, track & field, & weightlifting) in Eastern bloc nations were suspected to be augmenting their ability with some kind of pharmacological help. After the fall of communism in Eastern Europe and the reunification of Germany, documents surfaced proving that the East German sport establishment had conducted systematic doping of virtually all of its world-class athletes, under a program known as State Plan 14.25.
• In 1998 the entire Festina team were excluded from the Tour de France following the discovery of a team car containing large amounts of various performance-enhancing drugs. The team director later admitted that some of the cyclists were routinely given banned substances. Six other teams pulled out in protest including Dutch team TVM who left the tour still being questioned by the police. The Festina scandal overshadowed cyclist Marco Pantani's tour win, but he himself later failed a test. More recently David Millar, the 2003 World-Time Trial Champion, admitted using EPO, and was stripped of his title and suspended for two years. Still later, Roberto Heras was stripped of his victory in the 2005 Vuelta a España and suspended for two years after testing positive for EPO.
Six members of the Finnish cross country skiing team (four men and two women) were disqualifed for taking hemohes, a blood plasma expander, at the FIS Nordic World Ski Championships 2001 in Lahti, Finland. These six skiers became known as the Lahti six.
• In 2006, Spanish police arrested five people, including the sporting director of the Liberty Seguros cycling team, on charges of running a massive doping scheme involving most of the team and many other top cyclists. Several potential contenders in the 2006 Tour de France were forced to withdraw when they were linked to the scheme. Operación Puerto was mainly linked to doping in football, tennis and athletics, but the press concentrated on a small number of cyclists as Le Tour de France was about to start. For more details, see Operación Puerto doping case.
Less than a week after the 2006 Tour de France it was revealed that winner Floyd Landis had tested positive for an elevated testosterone/epitestosterone ratio (with normal levels of testosterone and deficient levels of epitestosterone) after his stunning stage 17 victory. Secondary tests have also confirmed the preliminary findings of deficient levels of epitestosterone resulting in a skewed T/E ratio.
