Then there's the data. Some people want to say that, actually, the number of people taking MDMA is going to increase more than the number of lives that are going to be saved by being able to detect the really bad stuff. I would say that, actually, no side has managed to put forward compelling evidence that it's one or the other. I don't think anyone's actually presented the data. The National Party stands up and says that the data that the Labour Party's put up is terribly compromised, and the Labour Party says that the National Party is bringing evidence from 1975, but neither of them have presented compelling evidence one way or another.
