Should doping in sport be legalised ?
In my point of view, it should not be, since, as in life, efforts make you go further, the same should apply to athletes. The best should be, for their effort, merit, dedication and many other factors that make them reach the top, and not for external chemical help. For me it's not fair game
Will it ever be possible to stop athletes breaking the rules to win?
I think that with more exhaustive and very regular controls, the situation can be controlled. That entails some extra expenses, but I think it would be an option
Are athletes who take drugs cheats or are they victims?
If they are the ones who really dope voluntarily, they cheat. There have been cases of involuntary doping, due to medications that athletes have taken. In 2015, a list of medicines entered into force, which can no longer be used in sport, since it produces doping.
