Random Drug Tests in Schools

So apparently the government is trying to make a push for random drug tests in schools. I've got to say I'm not impressed. Yes, the testing requires a parents consent, but really I can't see how this is anything less than an invasion of privacy. Not even that but it's a specific invasion of privacy in a targeted area. I mean this is basically treating children as criminals, it's only three steps from the nanny state. After all I can't think of any of my friends who have random drug tests at work, and it's not something I can ever see happening in the future. But setting up a policy of basically testing all children for drugs is ludicrous!

I'm also interested to know what happens to kids who are found to have taken them. Personally I have an issue with recreational drugs being illegal anyway. I mean they really are victimless crime. Now yes, I do understand it's not just as simple as that, and that they do need to be fully understood or else there are other worse consequences. But that's a matter of education and letting people make they're own choice.

However by enforcing random drug tests in schools you're effectively removing that choice from them, forcing the issue rather than letting people learn from their mistakes. Shouldn't this be an issue of informed and not enforced choice?
