Performance enhancing drugs (PEDs) have been used by athletes for centuries to improve performance. Early documented uses included swimmers in the 1860s taking drugs to speed up races. The first athlete to be disqualified for PED use was Hans-Gunnar Nilsson in 1968 after testing positive for cocaine and alcohol. Common PEDs used by athletes include anabolic steroids, human growth hormone, and creatine. However, using PEDs can have serious negative health effects and athletes caught using them often face bans and loss of titles and medals. Governing bodies continue developing better detection methods through urine and blood tests to curb PED use in sports.
