I was simultaneously depressed and then immensely heartened by an article I read on Comment Is Free earlier. The Labour MP John Robertson has written an article full of prejudice and nonsensical arguments regarding drugs policy. He also unbelievably even tries to smear Professor Nutt as a bad parent.
You should be fighting to protect the children from the risk that horse riding presents to them. You need to send out a strong message that horse riding is dangerous. Really, it should be illegal, because that will really discourage people from doing it. Ever since the new, stronger breeds of horse have become popular then the percentage of people who state that horse riding is a primary source of recreation has increased from 3.4% to 6.2%. If these so-called scientists say that this so-called horse riding is safer than using an angle grinder that doesn't detract from the need to be presenting a strong message.
Politicians are apt to invoke the precautionary principle when discussing illegal drug use, but it isn't quite as simple as that. The precautionary principle can result in harm to people. Perhaps the reason for including ecstasy with heroin in class A was to make people think that ecstasy was as dangerous as heroin (not true, but precautionary). But it is just as likely that people will conclude that heroin is as safe as ecstasy. That's the danger of lying, however good the motives.
