Nitazenes: The Next Wave in America’s Overdose Crisis. And Why Providers Must Act Now

Written By: Carmichael Finn · 10 comments

Nitazenes, an ultra-potent class of synthetic opioids up to 40 times stronger than fentanyl, are rapidly infiltrating the U.S. drug supply, often without people knowing they’re taking them. As these compounds drive a new wave of overdoses, treatment providers must act quickly: educate clients, expand harm-reduction efforts, and prepare for overdoses requiring multiple doses of naloxone.

Over the last decade, we’ve watched fentanyl reshape the landscape of substance use in America. Overdoses changed. Risk patterns changed. Treatment changed. And now, something even more potent is entering the supply—quietly and quickly.

What Are Nitazenes?

Nitazenes (benzimidazole-opioids) are a class of synthetic opioids first developed by a Swiss pharmaceutical company in the late 1950s but never approved for medical use in the United States. After decades of near invisibility, they began reappearing in illicit drug markets around 2019.
Clients aren’t asking for nitazenes. They’re falling into them.

How Potent Are Nitazenes?

Nitazenes range from slightly less potent than fentanyl to more than 40 times stronger, with some analogs reaching thousands of times the potency of morphine.
    • Fentanyl: 25–50× stronger than heroin
    • Some nitazenes: 5–9× stronger than fentanyl
    • Others: up to 25–43× stronger
A person can overdose on an amount they cannot see, taste, or detect. That’s the danger.

Why Are Nitazenes Showing Up in the Drug Supply?

    • Mixed with fentanyl
    • Sold as heroin
    • Hidden in counterfeit pain pills
    • Laced into benzodiazepine-like pills
    • Blended into powders to cheaply increase potency
People don’t know what they’re taking. That is the crisis.

What Providers Must Do Now

    1. Educate clients immediately using non-shaming harm-reduction language
    1. Encourage multiple naloxone kits
    1. Normalize conversations about supply unpredictability
    1. Integrate nitazene education into groups and sessions
    1. Train staff on rapid overdose recognition and response

Awareness is prevention. Education is prevention. Compassion is prevention.

Boundaries Without Compassion Can Become Cruelty, and Authenticity Without Boundaries Becomes Exploitation

In this article, Carmichael McKinley Finn, Executive Director at Recovering Hope, licensed therapist, addiction counselor, and adjunct faculty member, examines the federal government’s decision to designate illicit fentanyl as a Weapon of Mass Destruction. Drawing on frontline clinical and leadership experience, the piece explores why this framing raises deep concerns within behavioral health, how it risks repeating past policy failures, and where it could, if applied with clear guardrails, shift accountability toward the supply chains that profit from addiction rather than the people who need care.

The New Twist in the Fentanyl Crisis: Medetomidine Is Here

Medetomidine is now entering the illicit fentanyl supply, fundamentally changing the risks of overdose and withdrawal. Naloxone may reverse the opioid, but it does nothing for the powerful veterinary sedative that remains active in the body. As detox capacity shrinks, this collision between a more dangerous drug supply and a weakened treatment system is costing lives.
