The School Access to Naloxone Act of 2026 would provide federal grant funding to help schools train and equip personnel to administer naloxone and other emergency opioid overdose treatments to students. The bill targets public and private elementary and secondary schools and requires participating schools to maintain accessible supplies of these drugs and devices and ensure trained staff are available during all operating hours. To receive funding, schools must certify they have programs in place for trained administration and that their state has adequate civil liability protections for school personnel who administer these treatments in emergencies. The legislation defines eligible trained personnel as school nurses, health center staff, or other designated individuals who have received proper medical training in naloxone administration. The bill amends the Public Health Service Act to authorize appropriations for these school-based grants alongside existing opioid overdose reduction programs, though no specific dollar amount is specified in the text.
