High school students allowed to possess opiate antagonists.

HF 1641 requires Minnesota public school districts to maintain opiate antagonists (medication for opioid overdose emergencies) at all school sites, including at least two nasal doses per building. It allows high school students in grades 9-12 to possess and administer these medications to other students if their parent or guardian provides written authorization. Schools must follow state guidelines for storage and administration, and student possession is protected under existing law (section 604A.04). This bill directly affects high school students, schools, and parents/guardians by enabling student-led emergency response with parental consent.
