title: Chemical warfare: drugs in sports.
abstract: A number of substances have been used by athletes in an attempt to improve performance in sports. The use of these substances, which are referred to as ergogenic aids, has become widespread; some pose serious health hazards. Ergogenic aids are divided into five broad classifications: physiological, physical, psychological, nutritional and chemical. It is possible, although conclusive proof is lacking, that some substances may give an athlete who takes them an advantage over one who does not. However, the health hazards posed in general by these materials far outweigh any possible advantage.
