Are you For or Against drug testing in schools?

As random drug testing in schools becomes more common place, so does the ongoing debate about what good it will do. The idea of random drug testing is not to catch out those using drugs, but to act as a deterrent to try and stop children and teenagers developing drug addictions in the first place. But is it working to alleviate peer pressure and to stop young people taking drugs or is it having an unforeseen negative effect which is making our younger popular feel like their schools are presuming they are using drugs until they prove otherwise?
