Since becoming available over the counter, Naloxone has saved countless lives. In this episode, we explore how expanded access is helping communities confront the opioid crisis, the real-world impact on individuals, and the work that still lies ahead. Experts point to broader availability as a key factor in recent declines in overdose deaths, but the crisis is far from over. Many rural and marginalized communities continue to face devastating losses.

We look at how easier access to Naloxone is shaping outcomes, supporting harm-reduction efforts, and offering hope where it’s needed most.
