Doping scandals refer to incidents where athletes use banned substances or methods to enhance their performance in sports. These substances can include steroids, hormones, and stimulants, which are prohibited by organizations like the World Anti-Doping Agency (WADA). Such actions undermine the integrity of sports and can lead to severe penalties, including suspensions and loss of titles. High-profile doping scandals have involved famous athletes, such as Lance Armstrong, who was stripped of his Tour de France titles after admitting to using performance-enhancing drugs. These scandals often spark public outrage and lead to increased scrutiny and stricter regulations in sports to ensure fair competition.
