In Ancient Greece, athletes tried to improve their performance and gain the desired victory with the help of different means, just like today. The statistics provided in the infographic show that in modern times, some athletes also resort to unfair methods. They take performance-enhancing drugs (PEDs) which are believed to enhance physical activity level. By doing that, they break doping laws, violate the spirit of sport, and place themselves at potential or actual risks. AddictionResource authors warn that the use of PEDs can lead to tolerance and potential addiction and bring the end of an athletic career.
