The International Olympic Committee (IOC) published the first list of dopin
g classes in 1967. Since that time, there have been significant problems as
sociated with doping control in sport. Sport is a high profile, internation
ally recognised activity. However, operational inconsistencies exist betwee
n countries and between sports federations. Endogenous substances, such as
testosterone, human growth hormone (hGH) and erythropoietin (Epo) present p
articular problems in determining what constitutes 'normal' levels in athle
tes. In addition, there is no reliable method available for the detection o
f hGH and Epo through urine testing. Athletes continue to test positive for
banned drugs that are available over-the-counter despite their having been
taken inadvertently, without intent to enhance performance. Marijuana use
is becoming widespread in society and the impact of this in sport is becomi
ng evident.
Doping control, through the IOC list, must continue as a primary objective
for the IOC and the sports federations. Constant vigilance and a continued
willingness to respond rapidly to change is a prerequisite for such a list.
The IOC appears to recognise this need. There are, however, more fundament
al issues to be considered. The concept of doping control must be supported
by high quality research, effective education and international collaborat
ion. More research is needed into the factors which induce an athlete to ta
ke drugs and into the effect, if any, that education on drugs is having on
competitors. The most important area for change is the overriding need for
international collaboration between the IOC, governments and sports federat
ions. This applies to uniformity in the rules and regulations, consistency
in the application and level of sanctions and cooperation on the disseminat
ion of information and development of education policies.
