A Doping Scandal

When you sit down to watch the Olympics, you expect that you’re seeing the world’s best athletes competing on a level playing field.

The organization that runs the Olympics prides itself on that promise, and it presents the Games as being tougher on dopers than any other sporting competition. It claims to have the most rigorous drug testing. Those who test positive face serious punishments, including multiyear bans. And an independent entity — known as the World Anti-Doping Agency — has global authority to enforce a strict antidoping code.

But that system’s shortcomings have been on display at the Paris Games.

Over the past few months, my Times colleagues and I have uncovered a troubling pattern of positive doping tests in the Chinese swimming program. Twelve members of the Chinese Olympic team tested positive in recent years for powerful performance-enhancing drugs but were cleared to keep competing. Until our stories, none of the positive tests had been publicly disclosed, as required by the rules.

Concerns have spilled over to the pool deck in Paris, where some swimmers said the antidoping authorities had failed to ensure that these Games were fair. “I don’t really think they’ve given us enough evidence to support them with how this case was handled,” said Caeleb Dressel, one of the senior leaders on the U.S. team.

In today’s newsletter, I’ll explain how the Olympic drug testing system is supposed to function, and why, in some of the most high-profile cases, like this one involving the Chinese swimmers, it may not be working. And now the Justice Department and F.B.I. are investigating.

How it’s supposed to work

Each country is in charge of policing its own athletes. That means that the United States Anti-Doping Agency takes the lead in testing and investigating American athletes, the China Anti-Doping Agency does the same in its country, and so on.
