My stance is simple. It is not the job of any school or any government to regulate what I as a right-minded adult put into my body as long as I am not hurting anyone. Random drug tests break down any semblance of a relationship of trust between a school's administration and its students, as it automatically assumes that all students are criminals. Apart from being offensive on a very basic level, drug testing (especially in public schools) it expensive and a drain on taxpayers.
