Additionally, certain prescription medications, such as stimulants, can be on the list of substances banned by anti-doping agencies, Dr Baum noted. “It is important for psychiatrists to be familiar with these regulations, to determine whether the patient has a legitimate diagnosis such as ADHD, whether and when the medication is indicated, and to advocate on behalf of the patient if necessary.” Indeed, sport psychiatrists have “played an important leadership role in evolving and clarifying the role of therapeutic use exemptions for treatment of psychiatric illnesses when the desired treatment is on the World Anti-Doping Agency list of banned substances in sport.” 3
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."
