What are your thoughts on athletes and doping?

I suspect the rules are pretty clear and published. Therefore follow them or pay the piper.

The issue is really multi-fold

We are speaking of "competition" which leads to the idea that everyone is working fro the same base (natural) advantages. You get out of the competition what you put into it. Therefore, "performance enhancing" items (et al) violate the Spirit of competition. They can be deemed as an "unfair advantage.

The issue with Pharmacology (drugs) is that not everyone is going to know about the latest and greatest way to get maximum performance out of Physiology (body) for long or short term, AND there are trade-offs that can exist for each of those terms. You can take two athletes and one can choose to destroy his body in the short term to gain immediate advantage (like through stimulants), while the other can use long term benefits of another item to gain similar effects. Unfortunately, because the length of "Amateur careers" is measured in single Olympic games, this can create HUGE ethical issues.

Escalation of force or the Arms Race. If one person is perceived to be doing it, the entire playing field thinks they must do it to stay competitive. This acts as a shaping force within competition and leads to further ethical issues.

So although a person should absolutely be allowed to choose what they put in their own body, providing it does not actively hurt another, the private organization is also well within their powers to state that they want everyone to be competing "clean," and to develop rules that support that philosophy.

It's all about the winning because winning means sponsorship, which means money in the end. It's no more about the "games". Would be nice if everyone would just be natural and compete as humans not doped up.
