Illegal drug use in athletics refers to the consumption of banned substances by athletes to enhance performance or alter physical capabilities. These substances can include steroids, stimulants, and other drugs that may provide an unfair advantage in competitions. Organizations like the World Anti-Doping Agency (WADA) work to enforce rules and regulations to maintain fair play in sports. The use of illegal drugs can lead to serious health risks, including addiction, heart problems, and hormonal imbalances. Additionally, athletes caught using these substances may face severe penalties, such as suspensions or lifetime bans from their respective sports, impacting their careers and reputations.
