The tables set up near the entrance of the Big Night Live concert venue looked like a typical merch spread. But instead of band Tshirts and buttons, there were plastic models of human noses and a handful of naloxone nasal sprays.

This unusual display was part of a medical training for bar and restaurant workers — who are often the first to encounter people experiencing a drug overdose. Led by public health and medical professionals, a crowd of servers, bartenders, and security staff practiced administering naloxone, a medicine that can rapidly reverse an opioid overdose.
