"As required by Maryland law, the superintendent of schools shall establish
procedures to provide emergency medical care to any student, or other person
located on school property, who is reasonably believed to be experiencing an opioid
overdose.
a) The school nurse, school health services personnel, and other school
personnel identified by the superintendent of schools or designee, are
authorized to administer Naloxone or other overdose-reversing medication
to a student or other person located on school property.
b) The superintendent of schools shall develop and implement procedures to:
(1) obtain and store, at schools, Naloxone or other overdose–reversing
medication to be used in an emergency situation; and
(2) notify parents or guardians of students of such procedures at the
beginning of each school year."
I agree that carrying it seems like it falls under over the counter medication. Using it on another student off school property would fall under Good Samaritan Law. If an incident occurs inside the school, the nurse & security/admin should be notified first - let the medically trained adults assess the situation first.
