OF COURSE! Drug testing will help the school in order to determine those upcoming students if they are drug users or not. Drug test is a big help, especially for those students who want to take a medical course. They have to be strict, because these students will be future Medical Professionals someday.
On the other hand, if a student will get a positive result for drug testing, then, what action will the school be doing? Are they going to ACCEPT or REJECT those who are positive for drugs? If they accept, what are the next steps in order for the student to withdraw from that behavior? And if they will be rejecting then, they will be depriving the students from a much needed education.
Everybody needs a chance. I am not in a position to answer these kinds of questions popping in my mind right now, because I am not a school administrator (Maybe, someday. ☺).
Above all, the school administrator should know on how to make the school a clean environment or if possible, a drug-free school. Because the school is our second home. So if the school that we revolve in is not that good enough for us, then that would be the time for the school to do something, for the welfare and benefit of all.
