Happy March!! 🏀 We're glad you're here—let’s dive in and stay connected on all things harm reduction, data, community, and support 🪄

We understand that the landscape of drug overdose prevention is shifting rapidly. Many of you in government and frontline programs fear for your jobs, while others find themselves tasked with allocating opioid settlement funds. Drug overdose deaths are declining overall, but far too many people are still dying, with some communities facing greater burdens than ever. In some areas, harm reduction is flourishing; elsewhere, we witness the curtailing of lifesaving services. Younger activists are charting a new path forward, while established organizations rethink their strategies.

These are disorienting times. As a society, we can be—and always have been—many things at once. While it may feel like there is no cohesive path forward, we encourage you to recommit to meeting the needs of the people you serve. We are on the right path, and this is a time for fortitude. It is also a time for grace. There will be setbacks, and we can only suggest that **resilience through rest** will be an essential coping strategy. Hang in there; we got each other!

Our team attended the [NC Summit on Reducing OD](https://www.ncacc.org/events-training/nc-summit-on-reducing-overdose/), in Raleigh, NC March 18-20, 2025\. We engaged in insightful workshops, collaborative sessions, and inspiring keynotes [(slides)](https://cdr.lib.unc.edu/concern/scholarly%5Fworks/js956w76h?locale=en) that deepened our understanding and commitment to harm reduction strategies- one of those being our very own Dr. Nab😃 . The summit reinforced the power of community-driven solutions in reducing overdoses and supporting the health and well-being of people who use drugs. (Welcome to our new readers from the conference)

# Department of Data

In exciting news, scientists in Sicily, Italy have independently determined the precise mechanism of interaction between xylazine and the kappa opioid receptor. They also point to strong binding to serotonin receptors, confirming computationally *in silico* what [we observed experimentally](https://www.sciencedirect.com/science/article/pii/S2772392524000142).

An eye-opening component of their analysis was to create 500 new virtual molecules that had similar binding properties at kappa and serotonin receptors; they conclude: "The results of all the series \[of virtual molecules\] indicate that the chemical landscape for this class of compounds is still huge and that small modifications may further increase the activity of the parent molecule." **This is the scientific first warning note that cracking down on xylazine now could readily lead to the synthesis and emergence of new knock-off xylazine-alike street drugs tomorrow.**

See the [open access paper](https://onlinelibrary.wiley.com/doi/full/10.1002/ardp.202500041) by Floresta et al. for the \[highly\] technical details.

[Xylazine as an emerging new psychoactive substance; focuses on both 5-HT7 and κ-opioid receptors’ molecular interactions and isosteric replacement - PubMedXylazine, traditionally used as a veterinary sedative, has recently emerged as a new psychoactive substance, being typically ingested in combination with fentanyl derivatives and hence raising significant public health concerns. Despite its increasing prevalence, little is known about its molecular …![](https://storage.ghost.io/c/5b/77/5b77aa04-fe0b-45a2-a796-af3d64e3ea66/content/images/icon/favicon-192-1.png)PubMedGiuseppe Floresta![](https://storage.ghost.io/c/5b/77/5b77aa04-fe0b-45a2-a796-af3d64e3ea66/content/images/thumbnail/pubmed-meta-image-v2.jpg)](https://pubmed.ncbi.nlm.nih.gov/40091602/)

Back on the street, after climbing steadily last summer and into the fall, we [have started to see](https://deepnote.com/app/opioiddatalab/dexmedetomidine-Tracker-a401c37e-5255-4d15-87a1-252ee09f360d) a slight dip in xylazine and (dex)medetomidine in fentanyl samples since the start of the calendar year. This may be because folks are used to expecting it, or may signal yet another shift in the drug supply. This is a bit puzzling since we expected these substances to proliferate, or perhaps there is enough consumer pushback to change the market? We know there is deep dissatisfaction with the synthetic opioid supply right now. If what we are seeing in our raw data is borne out by more complete analyses, it could be that these trends may already be changing *before* the expected passage of the [HALT Fentanyl Act](https://drugpolicy.org/news/parents-police-and-advocates-condemn-senate-passage-of-halt-fentanyl-act-demand-lifesaving-health-solutions-to-fentanyl-and-overdose/). But we encourage caution in drawing too many conclusions!

# New Substances Detected

![](https://storage.ghost.io/c/5b/77/5b77aa04-fe0b-45a2-a796-af3d64e3ea66/content/images/2025/03/image-3.png)

We saw an influx of new pharmaceuticals submitted to our service, which we think could be due to folks testing out the limits of our detection capabilities. What's more relevant is that we (and other drug checking programs) are seeing an uptick in interest and samples containing (unregulated) hormones purchased online. Our methods are good at detecting them, and I don't think many of us are surprised. 

We'll get back to deeper analyses of new detections next month, but you can [see the new detections here](https://deepnote.com/app/opioiddatalab/Newly-Detected-Substances-2f2c3288-10a7-4e03-a6c2-57bb006b5823) in the meantime.

# 📖 Reading Room

A place for things that taught us something new and maybe you will learn something too!  
  
**JAMA Network Open:** More on the [**Drug Bust Paradox**](https://ajph.aphapublications.org/doi/10.2105/AJPH.2023.307329)**.** A [**new study**](https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2831697) out of San Francisco found a 74% increase in fatal opioid overdoses within 100 meters the day following drug seizure events. ([news coverage](https://www.sfchronicle.com/opinion/nualabishari/article/san-francisco-drug-overdose-20226194.php)) The risk persisted for a week. The study is consistent with another one [from Indianapolis](https://ajph.aphapublications.org/doi/full/10.2105/AJPH.2023.307291).  
  
**CDC’s Injury Center** has launched the **Mapping Injury, Overdose, and Violence Dashboard**, providing localized, real-time data on overdose, suicide, and homicide deaths down to the census tract level. This tool can help federal, state, local, and tribal partners better understand and prevent injuries and violence in their communities. [**Explore the dashboard today** to access timely, actionable data that can support public health strategies.](https://www.cdc.gov/injury-violence-data/data-vis/index.html)

**Bloomberg News** did a [nice story](https://www.bloomberg.com/opinion/articles/2025-03-21/opioid-crisis-deaths-including-fentanyl-are-down-here-s-why) entitled "What We're Getting Right Fighting the Overdose Epidemic," including an important perspective from Indigenous communities. It's behind a paywall, but, [ahem](https://archive.ph/).

Adams down in Sacramento at SANE with Shilo & the legendary Franz. Click hear to find out about data collection Adams is doing [here.](https://www.opioiddata.org/on-the-road-again/)

We wrapped up our third and last site of a FDA-funded study on how people actually use naloxone. Through 75 in-depth interviews, we explored how many doses people use, how folks modify their risk for overdose, and other themes. Stay tuned for more on this important work. And thanks to taxpayers for funding science that saves lives.
