The abuse of anabolic steroids by high school, college and other amateur athletes is a dangerous practice. Participants in amateur sports must be made aware of the physical and emotional dangers associated with steroid abuse. The "win at any cost " attitude embraced by some athletes must be redirected and replaced by personal dedication to the sport; a thorough knowledge of the sport's physical demands and requirements; maintenance of a healthy lifestyle; and, an appreciation of the satisfaction that comes from participation.
