My view on drugs - in sport, as in the rest of society - is simple. Make them legal and bring them out in the open. By far the most disturbing figures involve the 4 per cent of players who have been given injections without knowing what they were taking, and the 37 per cent who use creatine, a substance that may cause serious long-term liver damage. With drugs, as with sex, the two key words are "knowledge" and "consent". You have to know what you are doing, and you have to have an absolute right to choose what to do.
