Dumas had to strap Malléjac down for the journey to hospital at Avignon. Mallejac insisted that he had been given a drugged bottle from a soigneur, whom he didn't name, and said that while his other belongings had reached the hospital intact, the bottle had been emptied and couldn't be analysed.  Malléjac insisted that he wanted to start legal proceedings, and Dumas said: "I'm prepared to call for a charge of attempted murder." The incident was never resolved however, with Mallejac returning for subsequent Tours and denying any wrongdoing for the rest of his life.
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."
