"One approach to address student substance use is school-based mandatory-random student drug testing (MRSDT). Under MRSDT, students and their parents sign consent forms agreeing to the students’ random drug testing as a condition of participation in athletics and other school-sponsored competitive extracurricular activities. The programs are designed to supplement existing school-based substance use prevention strategies and have the twin goals of (1) identifying students with substance use problems for referral to appropriate counseling or treatment services and (2) deterring substance use among all students."
