Tests for narcotic analgesics and stimulants such as the amphetamines were introduced at the Olympic Games in 1968. Anabolicsteroids were not banned until 1974, when a suitable test was developed. Controversy has also focused on the legality of blood doping, in which an athlete receives a blood transfusion just before an event.
