Drug abuses in sport - Unwinnable?

It does, however, add to the growing moral pressure around professional atheletics and all professional sport to confront drug abuse by competitors, abuse often facilitated and encouraged by their managers, trainers and mentors.
Just as the war on drugs in wider society seems all but unwinnable it is hard to imagine that we will ever reach a point where we can say with real, justifable confidence that all competitors in a particular event, especially a lucrative one, are drug free.
