Performance-enhancing substances negatively affect sports by compromising fairness, altering athlete health, and damaging the integrity of competition. The use of such substances can provide unfair advantages, undermining the principle of fair play and diminishing the value of athletic achievements. Moreover, athletes may suffer serious health consequences, including addiction, cardiovascular issues, and hormonal imbalance. The visibility of doping scandals can inflict reputational damage on sports organizations and decrease public trust. Promotion of clean competition is crucial for preserving athlete welfare and maintaining the integrity of the sport, necessitating strict enforcement of doping regulations and educational initiatives.
