Cyclists and other athletes that need good stamina would use caffeine, cocaine, alcohol and strychnine in the 19th century. In the 1920s they realized they needed rules about drugs. In 1928 the IAAF was the first International Sport Federation (IF) to ban doping but many followed. At this time no tests were being made. The death of Knud Enemark Jensen in 1960 Olympics increased the chance of drug tests. In 1966 the UCI (cycling) and the FIFA (football) were the first to introduce drug tests. First Olympics that had doping test were the Winter games in Grenoble and the Summer games in Mexico. Most IF's had drug test by the 1970's. Anabolic steroids were not able to be detected yet. The drug finally got added to the prohibited list in 1974. Blood doping was banned in 1986. EPO was put on the banned list in 1990 and the test were introduced in 2000.
