Missouri school officials could soon institute new drug testing policies for their students. The U.S. Supreme Court has ruled that schools have the right to conduct random drug tests on students involved in extracurricular activities. Brent Ghan of the Missouri School Boards’Association says the number of school districts conducting tests could rise from the current half dozen which are testing students involved in athletics. A previous U.S. High Court ruling allowed schools to conduct random drug tests of student athletes.
