OK, next you have to ask yourself, (and answer) who allows such teachers and drugs to be in our classrooms?
Teachers Unions and teachers (most) push for the medicating of children to make their lives easier despite knowing how it affects a child's ability to learn and comprehend. Makes it easier to manage a classroom. Learning be damned. Unions make it very difficult if not near impossible to fire a teacher for anything other than physical or sexual abuse. Incompetence is not grounds to terminate a teacher. In some states technically it is, but Unions make near impossible.
