Drug abuse remains a serious problem in schools. The government's repeated anti-drug campaigns bore little fruit.
The problem is that despite all the publicity about the dangers of taking drugs, many young students are led by curiosity and peer pressure to try out drugs. They then fall into a self-destructive habit.
While it's primarily the responsibility of parents to make sure their children stay away from drugs, often they are too busy to keep a close watch on the children.
Therefore, the government's zero- tolerance policy on drug abuse among teenagers through mandatory drug testing is a necessary measure.
The aim of mandatory drug testing is not to punish or humiliate drug-users at school. It is to serve as a strong deterrent and as a means to find students who need help to tackle their addiction.
