In this episode, Vanda Felbab-Brown discusses the fentanyl and opioid crisis in Nevada with Dr. Anne Weisman and Dr. Sara Hunt of the University of Nevada, Las Vegas (UNLV). They analyze the high rates of opioid misuse in the state and the resulting strain on health systems and behavioral health workers as well as coroners, a professional group essential in responding to drug use, but often neglected in policy focus. Their conversation explores the significant innovations that the state of Nevada adopted as a result of UNLV research and policy work and ways in which it can serve as an exemplar to other U.S. localities struggling with inadequate resources to deal with fentanyl.

Growing up in California, the historically most important destination for migrants in the Americas, the Spanish word exodo had a familiar ring. My Salvadoran parents used it to describe their journey along the Pan-American Highway as they left El Salvador for San Francisco in the 1950s.

The tribes imagine that their own casinos would receive any business lost by the card rooms, but they aren’t the only ones competing with the card rooms.

When you daydream about your retirement, you may be picturing traveling, volunteering and spending time with grandkids. One thing that’s likely absent from the dream? Struggling to move around your own home.

The summit, presented by NPHY in partnership with Las Vegas Sands and the UNLV Greenspun College of Urban Affairs, aims every year to go beyond just creating more exposure for a population frequently described as invisible or voiceless. NPHY CEO Arash Ghafoori says the summit’s information-filled morning and action-taking breakout sessions in the afternoon are curated in the same strategic way the organization approaches the issue of youth homelessness.
