Doping (sport)

In sports, doping refers to the use of performance-enhancing drugs, such as anabolic steroids, particularly those that are forbidden by the organizations that regulate competitions. Some doping substances, however, are permitted in low doses (alcohol and caffeine). Another form of doping is blood doping, either by blood transfusion or use of the hormone erythropoietin (EPO). Also considered "doping" by many is the use of substances that mask other forms of doping.
