Establishes provisions relating to drug overdose prevention and investigation of drug-related deaths

HB 3113 requires public buildings to store naloxone (an overdose reversal medication) in first aid kits and near defibrillators, and to inform occupants of its location and emergency procedures. It designates April as "Fentanyl Poisoning Awareness Month" and mandates school districts to establish drug-free advisory committees with community input, implement grade 6-12 fentanyl education, and develop prevention programs for students. The bill also directs law enforcement to investigate all drug-related deaths as homicide crime scenes, regardless of criminal charges, and to collaborate with schools on drug trafficking prevention in school zones. These provisions directly affect public buildings, school districts, and law enforcement agencies across Missouri.
