I don't care if athletes smoke pot. In fact unless it can be proven that it would give them an unfair advantage. I don't care what kind of drugs they do.
I must say though, the fact that boxing's testing allows you to pump yourself full of anabolic steroids, growth hormone and EPO and never really try to expose you, but will catch you out if you've had a Spliff is ****ing ridiculous. Like the UFC, happy to allow people to increase their testosterone levels by 400% and fight someone, but touch that weed and you're serving a ban !!
