Well, athletics is now the most drug-tested sport on the planet.
If you follow almost any other sport I shudder to think of the drug use going on - but not detected.
Take for example, the boxer Manny Pacquio who has refused to take an Olympic type drugs test. Very Dodgy!
And football players, I bet they've been doped up for decades!
Even participants in "sedate" sports like bowls and snooker can/do/have benefit from drugs.
We know, for example, darts players have been done for taking drugs.
Sport is great. If every kid in the country would take up a sport, the benefits to society would be enomous.
And, the "Olympic Effect" will certainly result in a huge take up of sports by children who otherwise wouldn't have been drawn into sports.
