We're still energized by everything our toxicologists brought to 2025, and excited to carry that momentum into the year ahead.​

From presentations to poster sessions, our team spent 2025 advancing both clinical and forensic toxicology through research, collaboration, and education. Our toxicologists shared insights that support clinicians, investigators, and laboratories in navigating an evolving toxicology landscape.​

A few highlights our team was proud to contribute in 2025:​
✅ "Medetomidine: A Rising Toxic Adulterant in Illicit Drugs"​
✅ "Drug-facilitated crime: A review of findings between 2019 and 2023​"
✅ "Can 4-ANPP Concentrations Differentiate Illicit from Licit Fentanyl?​"
✅ "New and Emerging “Nitazene” Analogues Appearing in Medicolegal Death Investigations"​
✅"Prevalence of Xylazine in Umbilical Cord Tissue, October 2023-September 2024​"

And that’s just a snapshot of the work shared throughout the year. ​

Drive Sober or Get Pulled Over.​

Each year, the holiday season brings celebration — but also a rise in impaired driving incidents.​

At NMS Labs, our mission is to advance forensic and clinical science that saves lives. Through comprehensive DUID (Driving Under the Influence of Drugs) testing and expert toxicology analysis, we support law enforcement and public safety agencies nationwide in identifying and preventing drug- and alcohol-impaired driving.​

Our testing panels detect a wide range of substances — from alcohol and THC to emerging synthetic drugs — providing the scientific evidence needed to promote accountability and safer communities.​

This holiday season, we remind everyone: Celebrate responsibly. Drive sober. Arrive alive.​

Giving Tuesday!

NMS Labs is honored to continue its longstanding collaboration with the CFSRE, a program of the Fredric Rieders Family Foundation. The CFSRE’s innovative NPS Discovery initiative plays a critical role in rapidly detecting emerging drugs and adulterants in the drug supply, helping public health and safety professionals stay informed about the latest trends affecting their communities.

Aligned with the vision of NMS Labs and foundation founder Dr. Fredric Rieders, the CFSRE also provides meaningful STEM mentorship to high school students, offering hands-on exposure to a wide range of forensic science disciplines. In addition, they deliver globally recognized Master of Science programs in forensic science through partnerships with local universities, supporting impactful education and training for learners worldwide.

In this season of giving, consider donating to the CFSRE so that they can continue their mission of nurturing the growth of future forensic scientists while delivering real time critical insights on drug trends throughout the country.

As the holiday season approaches, we encourage everyone to stay safe on the night before Thanksgiving, often referred to as Blackout Wednesday. While this night is a time for celebration, it’s important to remember that alcohol and other substances can affect
judgment, behavior, and safety.​

Whether you’re going out or staying in, be mindful and take steps to protect yourself and others. If you’ll be in situations where substances are present, plan ahead to get home safely using a ride share service or a designated driver. For those traveling, please stay
alert and cautious on the roads. We also want to thank law enforcement for their ongoing work to keep our roads and communities safe from impaired driving.​

NMS Labs wishes everyone a safe and happy Thanksgiving!​
