The DOH Drug User Health Team recently completed an overdose response training video: https://www.doh.wa.gov/YouandYourFamily/DrugUserHealth/OverdoseandNaloxone/NaloxoneInstructions
The link can also be found in the body of the Statewide Standing Order to Dispense Naloxone.
The video is 6.5 minutes, and covers the basics of overdose recognition and response, including how to use the two most common forms of naloxone, the naloxone vial for intramuscular injection and the intransal Narcan® device.
