Doping is a term used in sports to describe the use of banned substances or methods with the intention of improving athletic performance. It can include taking drugs, using steroids, hormones, and other substances that are not naturally produced by the body. Doping is considered cheating because it gives an unfair advantage to those who use these substances over those who do not. The practice of doping in sports has been met with strong opposition from various organizations and governing bodies, as they strive to maintain fairness and integrity in athletic competition.
