Upstream Overdose Prevention: Why the US Should Pilot a Safer, Regulated Drug Supply
The United States overdose crisis is driven in large part by an increasingly unpredictable and contaminated drug supply, including fentanyl and its analogs and emerging adulterants such as xylazine and nitazenes. Drug checking interventions such as fentanyl test strips and Fourier Transform Infrared Spectroscopy are essential for harm reduction, yet they also highlight a central policy failure: they place the burden of safety on people who use drugs (PWUD) and frontline programs after drugs have already entered an unregulated market. We argue for a more pragmatic upstream public health response, authorizing pilots of a safer, regulated drug supply (“safer supply”), broadly defined as legal and regulated access to psychoactive substances or close pharmaceutical alternatives intended to reduce reliance on the unregulated drug market. International experience, particularly models in Switzerland, Canada, and the United Kingdom, demonstrates feasibility and suggests potential benefits, including improved health and social stability, reduced reliance on unregulated supply, and reduced acute care utilization in some settings. For the United States context, we propose a portfolio approach: near-term, healthcare-based pilots leveraging existing controlled-substance infrastructure (eg, opioid treatment programs, clinics, pharmacies, and tech-enabled dispensing) while preserving space for community-governed models with legal protections and longer-horizon, state-regulated pathways. We address predictable concerns (secondary sharing, youth initiation, community impact, mixed population-level findings) and outline guardrails and evaluation strategies that are PWUD-led, nonpunitive, and methodologically rigorous. We conclude with concrete policy actions to authorize pilots, establish legal protections, fund independent evaluation, and scale models that demonstrably reduce harm while integrating with harm reduction and treatment services.

Syringe Services Program Legal Restrictions Are Counter to Public Health and the Experience of People Who Use Drugs
Drug overdose and drug-related harm are major sources of preventable injury and death in the United States. The criminalization and stigmatization of people who use drugs continues to inform law and policy that is ineffective at preventing this harm. While harm reduction interventions such as syringe services programs (SSP) have been widely adopted, the laws that govern these programs often impose restrictions that make SSP operation more difficult and less effective. For example, 23 state permit SSPs to operate only if they receive authorization from state or local government officials, and 5 states continue to adhere to some version of a “one for one” exchange model. This article presents data on these and other state laws that impede the work of SSPs. It also highlights ways the experience and expertise of people who use drugs can be integrated into the creation and implementation of SSP operational models. Removing barriers to these life-saving programs is critical to decreasing drug-related harm.

A Prehospital Quality Improvement Framework to Reduce Mortality and Other Harms Associated with Opioid Use Disorder
In response to the escalating overdose crisis there is an urgent need for innovative strategies to reduce overdose death. Emergency Medical Services (EMS) is uniquely poised to reduce mortality and other harms associated with opioid use through prevention, harm reduction, and treatment, yet there is a paucity of nationally recognized best practices or quality measures to guide prehospital quality improvement (QI) efforts related to opioid use disorder (OUD). A multidisciplinary team of subject matter experts in addiction medicine, EMS, public health, and QI was convened to develop recommendations for a model QI framework for prehospital OUD prevention, harm reduction, and treatment based on the Model for Improvement framework. This article introduces a comprehensive EMS QI framework, aimed at not only addressing acute opioid-related emergencies but also fostering long-term strategies to mitigate mortality and other adverse outcomes among individuals with OUD. Grounded in evidence-based practices and informed by collaborative expertise, this framework represents a pivotal step toward enhancing the effectiveness and responsiveness of EMS in combating the multifaceted challenges posed by OUD.

The role of prescription opioid and cannabis supply policies on opioid overdose deaths
Mandatory prescription drug monitoring programs and cannabis legalization have been hypothesized to reduce overdose deaths. We examined associations between prescription monitoring programs with access mandates (must-query PDMPs), legalization of medical and recreational cannabis supply, and opioid overdose deaths in United States counties in 2013-2020. Using data on overdose deaths from the National Vital Statistics System, we fit Bayesian spatiotemporal models to estimate risk differences and 95% credible intervals (CrIs) in county-level opioid overdose deaths associated with enactment of these state policies. Must-query PDMPs were independently associated with on average 0.8 (95% CrI, 0.5-1.0) additional opioid-involved overdose deaths per 100 000 person-years. Legal cannabis supply was not independently associated with opioid overdose deaths in this time period. Must-query PDMPs enacted in the presence of legal (medical or recreational) cannabis supply were associated with 0.7 (95% CrI, 0.4-0.9) more opioid-involved deaths relative to must-query PDMPs without any legal cannabis supply. In a time when overdoses are driven mostly by nonprescribed opioids, stricter opioid prescribing policies and more expansive cannabis legalization were not associated with reduced overdose death rates.
