Generate text that refutes this claim: Prevent drug use  There is a clear and present problem with drug use among children and teenagers in many countries. According to the UK Department of Health, in 2002-2003 38% of 15 year olds had used illegal drugs, as had 8% of 11 year olds [1] . The fact that all of these children would have been in schools at the age of 15 shows that current policies of targeting the supply train of drugs (for example by arresting drug dealers and intercepting drug shipments) is failing to protect children. Therefore a more direct approach that intervenes at the point of consumption is needed, most crucially for children and teenagers, as their years in education are crucial for both their personal development and their realization of their future education and employment potential.  Drug use at a young age may lead to lifelong use and addiction. Random drug testing in schools will allow for vulnerable children's drug problems to be discovered, and assist the state in getting them the help they need to get off drugs. Random testing is especially valuable in this scenario because many infant and teenage drug users will try to disguise their drug use from parents and teachers and so avoid detection through avoiding suspicion, a tactic which will prove of no use against random drug tests which will likely affect all students at one point or another. It should also deter many students from starting taking drugs in the first place as the prospect of them being caught becomes far more likely, as they know disguising their drug use will be of no use.

Drug users' decisions are influenced by an irrational desire to fulfil the chemical need they feel (to get their 'high'). As a consequence many drug users in schools will simply look for ways to evade drug testing regimes that are put in place. This is a problem as drug testing is most likely to catch cannabis users (the most widely-used drug among teenagers) [1] , as cannabis endures longer in the body than other more dangerous drugs such as heroin and cocaine. This can potentially lead would-be cannabis users to switch to these harder drugs, most of which generally have significantly shorter detection times and/or are less likely to be tested for. [2] This harm clearly outweighs the benefits of catching or deterring a few more cannabis users.  [1] Department of Health. “Statistics on young people and drug misuse: England, 2003”.
