In November 1942, the Italian cyclist Fausto Coppi took "seven packets of amphetamine" to beat the world hour record on the track.  In 1960, the Danish rider Knud Enemark Jensen collapsed during the 100 km team time trial at the Olympic Games in Rome and died later in hospital. The autopsy showed he had taken amphetamine and another drug, Ronicol , which dilates the blood vessels. The chairman of the Dutch cycling federation, Piet van Dijk, said of Rome that "dope – whole cartloads – [were] used in such royal quantities." 
CAS reviewed the ban and increased the length to 18 months, eliminating Johaug from defending her World Cup title and participating in the Pyeongchang Olympic Games in South Korea in 2018. While conceding the situation was “inconsistent with her otherwise clean anti-doping record” , the CAS panel also noted Johaug didn’t review the packaging where the prohibited anabolic steroid was a listed ingredient nor did she acknowledge the doping warning printed in red. FIS had earlier cited Johaug for not reading the warning in red as well as using a medication that was purchased outside of Norway and that she wasn’t familiar with.
