Athletes use drugs for many reasons.
Some use drugs for medical need. Finally, some sports people use drugs, including illegal drugs, recreationally. It is possible to take a different view of each of these forms of drug use. For athletes taking a drug for medicinal purposes, it may be important for them to make the medical condition known to testing authorities well in advance of any test being performed. For the inadvertent user, there is a need for more education so that the rules of competition, as they relate to drug use, are well known and understood.
