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." 
Also important in the treatment of drug dependency is helping the parents, other family members, and friends of the addicted person refrain from supporting addictive behaviors (codependency). Whether providing financial support, making excuses, or failing to acknowledge the drug seeking and other maladaptive behaviors of the addict, discouraging such codependency of loved ones is a key component of recovery. A focus on the addicted person's role in the family becomes perhaps even more significant when that person is a child or teenager, given that minors come within the context of a family in nearly every instance. Drug dependency treatment for children and adolescents is further different from that in adults by the impact of drugs on the developing brain, as well as the younger addict's tendency to need help completing their education and achieving higher education or job training compared to addicts who may have completed those parts of their lives before developing the addiction.
