  Doping refers to the utilization of banned substances or methods to improve athletic performance. It is condemned in sports due to its unfair nature and the risks it poses to the well-being and honesty of athletes and the notion of fair play.

• Disadvantages of Doping:

    Doping agents can lead to significant health issues. These substances have the potential to cause lasting harm to organs, disrupt hormonal balance, trigger cardiovascular complications, and even result in life-threatening situations.

    Example:

    An athlete who abuses performance-enhancing drugs may suffer from heart problems or kidney failure in the long term.

  • Unfair Competition:
