Then there's the politics of it. What do parents really think about this legislation? Well, there are two things they might think. They might think pill testing will encourage their kids when they go to a festival to take drugs like MDMA. If they know it's pure, the logic goes, then they might be more likely to try it than if they were unsure and worried that it could have horse tranquilliser in it. And no doubt, for some kids, that is actually true. Allowing pill testing will mean some kids will try MDMA whereas they might have been discouraged by the risk of there being bad things in it. But surely even the opponents of this legislation have to concede that there will also be kids who are saved from taking much more dangerous things because they are able to test and find out that the dangerous stuff is inside the pills that they have.
