Given the recent fuss over the likes of Marion Jones and Dwain Chambers using performance-enhancing drugs, I thought it was a bit odd that they considered the use of cannabis in the same way as EPO, or steroids, given that on the occasions I’ve indulged I would have struggled to get changed into my trunks, let alone swim a length or two.

Maybe being an uber-athlete it affected him differently, but I would have paid good money to see him in action.
