While there are many substances used that might be considered ineffectual or physiologic, the two main categories of substances considered as doping agents are stimulants and anabolic steroids. No substance is as yet known that will improve an athlete's performance. Often such substances are taken in error rather than in a misguided attempt to improve one's ability. These substances can be dangerous and, because of this, doping rules were established basically to protect the athlete. Anabolic steroids are particularly dangerous; they usually are taken by those engaged in lifting or throwing sports in an attempt to improve performance by increasing muscle bulk. There is as yet no scientific proof that performance is improved. Dope testing for stimulants should be carried out in a quantitative rather than qualitative manner so that the athlete who has taken a small amount of a so-called stimulant (such as an asthma or common cold preparation) would not be excluded from competition. Rigid testing for anabolic steroids should be continued.
