What do you think about mandatory drug testing for students?

My county just passed a policy that requires student athletes, drivers and those in extracurricular programs such as band and show choir to sign consent forms for random urine tests. Students would be asked to go to the restroom and urinate in a cup with a medical worker standing outside to listen to “normal sounds of urination”. I don’t have kids but I find this policy to be an invasion of privacy. What do you parents or even non-parents think of this policy?
