Drug testing programs in schools are designed for help of drug addict students. These programs guard the health of addicts. Many schools are organizing drug tests programs for students entering sports, physical activities and non-active optional activities such as chess club or the debate team.

Testing can also be an effective way to prevent drug use. The hope that they may be arbitrarily tested is sufficient to make some students stop using drugs or never start in the first place.

Students who use drugs or alcohol are statistically more likely to drop out of school than their mates who don't. Dropouts are related more likely to be unemployment and to commit crimes. If drug testing deters use of drug then everybody benefits even students, their families, their schools, and their communities. Drug and alcohol abuse decreases the capacity of learning of student that is very necessary for student to gain success.

It has been seen in study that the students who use drugs are more likely to bring guns and knives to school and increases the probability of physical attacks, property destruction, stealing, and cutting classes by them.

The purposes of drug testing in schools are:

•Students will observe point of view in favor of, and against, drug testing in schools.
•Students will express their opinions concerning drug testing in schools.
•Students will think and discuss consequences of a policy for or against drug testing

Schools have a responsibility for students about their privacy, so it is necessary that the result has shown only to the people and their parents. The results should not be common with anybody else, not even teachers.

The objective of this type of arbitrary testing in schools are to put off drug use among teens by not telling anyone who or when they are to be tested in proceed. However, critics assert that accidental testing introduces a supposition of guilt, and is a violation of privacy if the client is not really intoxicated during working hours.
