Generate text that refutes this claim: School's duty of care  Peer pressure drives most drug use among children and teenagers. [1] The fact that the state requires all children to be engaged in education means that most of them will be gathered into large groups in schools for most of the day, five days a week, essentially creating the necessary conditions for peer pressure to take place and be powerful. This occurs as some children face ostracism or exclusion from their peers in the social environment that the state compels them to be in if they refuse to take illegal drugs, if drug use is deemed necessary to be 'cool' or 'popular'.  It is, generally, the state that operates a western liberal democracy’s education system. Under circumstances in which children are placed into the care of the state, and are made vulnerable to peer pressure the state has a duty to ensure that children are not coerced into using drugs. This means that concerns of 'privacy' are secondary to protecting the choice not to take drugs, as ensuring the 'privacy' of all students by not having random drug tests empowers some students to socially coerce other students into using drugs when they otherwise would not.  Random drug tests help prevent cultures or norms of drug-taking (by which it can become the 'cool' thing to do) by ensuring that most drug users will be caught and helped to quit, thus protecting the choice of others not to be pressured into drug use.

None of these benefits apply if the peer pressure simply switches to harder drugs which are harder to test for or less likely to be tested for.  Moreover, peer pressure can exist outside of schools, and amongst older teenagers who have the choice to vary their attendance of sixth forms, FE colleges or senior high schools. Random drug testing could lead to older children being pressured to cut classes for prolonged periods of time, in order to take drugs, in order to be thought of as cool.  Teenagers are also notorious for believing that “nothing bad can happen to me”, even if that bad thing becomes more likely (such as being caught with a random drugs test). This is demonstrated by the fact that many teenagers already engage in illegal drug use despite the reasonably high chances that an adult will see them using drugs, smell smoke or notice the drug's effects on them in the status quo.
