In 2002 the Supreme Court ruled that schools could require random drug tests of students participating in competitive after-school activities such as athletics. Does drug testing reduce use of illegal drugs? A study compared two similar high schools in Oregon. Wahtonka High School tested athletes at random and Warrenton High School did not.

No it does not

Explanation:

Doing random drug tests does not reduce the use of drugs in High School athletes, unfortunately. But it does reduce the number players that are on drugs from participating in the games.

Drug use often develops into addictive behaviour that cannot be curbed even with the threat of not participating in extra-curricular activities. The reason for doing drugs must be addressed and this is the only way that drug use can be curbed. Since this is multifaceted and is a subjective approach it is often out of the realms of resources available.

The only way to curb the outward appearances is to not allow the players that are tested positive for drugs to stay off the teams. Other players that aren't on drugs are filling in and the numbers look better but unfortunately the problems remain.
