I think doping in sports shouldn’t be legalised, but I know it’s a very complicated question. First of all, I suppose that not all the illegal ways sports people can use to enhance their performance can be detected in a drugs test. If a substance or a process is banned, someone can imagine another way to avoid controls. So, it’s impossible a good control.
In spite of having these difficulties, authorities should continue controlling the use of drugs in sports. Using chemical substances to modify some characteristics (for example, to increase strength and speed) is unfair and unhealthy. Furthermore, if doping were legalised, which one could be an acceptable limit? Should we accept any possibility?
In my opinion, the high level of competitiveness we can see in sports is not good. There is a lot of money around sport, and I think that it has no sense. It’s unfair that some sportsmen (I say sportsmen, not sportswomen) earn lots and lots of money, while people who work for their community (like teachers, doctors, nurses, etc.) have insufficient salaries (in case they have a job). If money and sports were not mixed, probably sports people wouldn’t be pressed in this way, and the temptation of doping wouldn’t be so strong.
