There are several things to consider about the Kelli White doping storm.

White won both sprints with room to spare in Paris

This is the first: I don't care if the substance she's taken is specifically on the banned list or not.

Not all drugs are on that list. They don't have to be - that is why the phrase "related substances" is there.

The exact substance that you have taken does not need to be named.

In my opinion, what Kelli White has done contravenes the spirit of athletics. Now this whole business will overshadow what was a wonderful night in the Stade de France.

Rather than talking about the gold medals won by Eunice Barber in the long jump and the French 4x100m relay team, we are mired in a messy doping case.

There are lots of questions that need to be answered.

How did the news of the positive test leak out to a French newspaper before either the athlete or US Track and Field were told?

While we should be pleased that we found out, this is not the way it should have happened.

The anti-doping system has to be legally watertight or it cannot work.

If the IAAF follows the principle of strict liability, as it should, White will lose both her gold medals.

That is certainly what you would expect after the media conference given by IAAF vice-president Arne Ljundqvist on Saturday night.

If they don't, that sends out entirely the wrong message - that she was okay to take the substance.

The American team are coming out of these championships very badly.

First we had Jon Drummond's antics, then the furore over 400m champion Jerome Young's failed drugs test in 1999.

And now Kelli White.
