This document discusses the use of drugs and supplements in sports. It notes that athletes have long sought competitive advantages through substances like alcohol, mushrooms, and caffeine. Today, supplements are legal if they do not enhance performance or harm health. Illegal drugs include anabolic steroids, hormones, painkillers, and stimulants. However, the line between legal and illegal is not clear cut. The document asks students to consider where to draw the line and complete a homework task outlining their own system for the legalities of short-term technical preparation substances in sport.
