Should performance-enhancing drugs be legalized?The use of performance-enhancing drugs (PEDs) in sport, also known as performance-enhancing substances, dates back to the first Olympic Games in Greece ( Wada, 2010). This illegal practice, then perceived as part of sport, is today considered a serious offense. Most recently, in 2012, the Court of Arbitration (CAS) banned Jan Ulrich, a German cyclist, for a period of two years for using PEDs (CAS, 2012). Even more recently, another cycling icon, Lance Armstrong, was banned for life this time by the United States Anti-Doping Agency, as part of its ongoing fight against PEDs (USADA, 2012). Today, athletes are subject to incessant doping tests throughout the year and in 2012 alone, USADA conducted 8,490 tests, more than half of which were out of competition (USADA, 2012b). The fact is that many substances banned by the World Anti-Doping Agency (WADA) have no reason to be banned because they are produced naturally by the human body, for example human growth hormone, levels of which can decrease (Molitch et al., 2011). Furthermore, the fight against drugs in sport is futile, because doping tests cannot track all the different types of doping substances and methods (B. Foddy, J. Savulescu, 2007). For example, EPO, a hormone that stimulates the production of blood cells, was banned in the early 1990s but could not be detected until the year 2000 (AMA, 2011). Nowadays, athletes who use PEDS outnumber those who do not, which means that there is no fair play in sport (Goldstein, 1990). It is for these reasons that the use of doping substances in sport should be legalized. For starters, the World Anti-Doping Agency has banned a number of substances, such as human growth hormone (HGH), which...... middle of paper ...much of it rains. (Noakes., 2004). This shows that the use of PEDs is in no way contrary to dedication and commitment, which are some of the values ​​that characterize the spirit of sport. Despite this, WADA stripped Lance Armstrong of all his medals in 2012 simply because he had used PEDs during his career, effectively burning years of hard work to ashes as if his victories were just the result doping. use PEDs to compensate for certain deficiencies and improve their mental and physical condition, if they deem it necessary. Indeed, it is up to the athlete to judge which substance he must use to be at his best in competition. Additionally, due to the cost and failure of drug tests over the years as well as the lack of fairness in sports today, now is the time to legalize PEDs..
