Caught in the middle

DO YOU AGREE THAT DRUG TESTING SHOULD BE A REQUIREMENT FOR SCHOOL ADMISSION?...
This is one question that is easy to answer, yes ofcourse! But the hard question is WHY?
Why require drug testing? This is to ensure safety of students inside the campus. Also, it sets a standard, that the school is prestigious enough not to accept drug-users. Drugs can cause many adverse effects to the person using it, may it be physically, mentally or socially. It can change one person in many ways. Having a drug user as a student and part of the school isn't a good idea, they can serve as influences to non-users to become potential users, this is in relation to the rampant issue of "peer-pressure." Furthermore, it can be done just as a formality thingy but there's nothing to lose for the part of the school and the incoming students if this is implemented, if you are drug-free why contradict it, right?. :)

BUT WHAT IF IT WAS NOT A REQUIREMENT?
If drug testing isn't a requirement in school, it can also be good in some perspectives. It can give a chance for drug users to go to school, knowing that they will now be apprehended on their choice of being users. People are entitiled to freedom, what if it was their choice to be users? Should they be deprived from learning or going to school? This issue may violate their freedom..

Think about it... Its a very good thought to ponder. Yes, using drugs is bad.. But will you deprive a problematic user from wanting to learn? Will you deprive a user of education?...
