Immediate Action Required to Tackle Overdose Crisis Linked to Stimulants and Fentanyl
Overview
The fourth wave of the opioid epidemic involves increased stimulant use contaminated with fentanyl, leading to rising overdose deaths, especially among Black and American Indian/Alaskan Native populations. Evidence-based interventions like contingency management (CM) and structural competency in provider education are critical to addressing this crisis.
Background
The opioid epidemic's fourth wave is marked by the contamination and co-use of stimulants such as cocaine and methamphetamine with synthetic opioids like fentanyl. This has caused a surge in overdose deaths across the US, with unregulated drug supplies increasing the risk of unintentional fentanyl exposure. Stimulant use has risen significantly, with methamphetamine use disorder notably increasing among Black individuals. Racial disparities in overdose mortality have widened due to systemic inequities in treatment access and stigma.

Key Findings
The fourth wave of the opioid epidemic is driven by stimulant use contaminated with fentanyl, increasing overdose risk.
Stimulant use and stimulant-opioid co-use are rising, disproportionately affecting Black and AI/AN populations.
Structural factors including stigma, implicit bias, and inequitable access to treatment exacerbate racial disparities in overdose mortality.
Contingency management (CM) is an evidence-based, effective intervention for stimulant use disorder but is underutilized due to regulatory, funding, and awareness barriers.
Structural competency education for providers can reduce implicit bias and improve culturally appropriate care for people with substance use disorders.
Scaling harm reduction, peer engagement, and culturally adapted interventions are essential to address this crisis equitably.
Clinical Implications
Clinicians should incorporate structural competency principles to address systemic barriers and biases affecting patients with stimulant use disorder. Expanding access to contingency management programs and culturally tailored interventions can improve treatment outcomes and reduce overdose risk. Multisectoral collaboration and harm reduction integration are vital to effectively respond to the evolving overdose crisis.
Conclusion
The escalating stimulant-opioid overdose crisis demands immediate, equity-focused interventions including provider education, evidence-based treatments like contingency management, and structural reforms to reduce disparities and save lives.
