Sport

In sports the word doping means the use of performance-enhancing drugs, particularly those that are forbidden by the organizations that organize competitions in a certain sport (see steroids). Some doping substances, however are permitted in low doses (alcohol and caffeine). Also considered "doping" by many is the use of substances that mask other forms of doping.

In most sports, controls are being made to check for doping among top level athletes.

Doping is often considered a form of unfair competition; also, many forms of doping can be hazardous to the sporters' health, with symptoms sometimes not occurring until after the sporting career.
