Impairment Perspectives

Setting the Bar: Inside the National DUID Testing Recommendations with Amanda D’Orazio

In this episode of Impairment Perspectives, host Joey Jones sits down with forensic toxicologist Amanda D’Orazio of NMS Labs for a conversation about the evolving world of drug-impaired driving toxicology. Amanda shares her path into forensic toxicology, her work helping shape national DUID testing recommendations, and the importance of standardizing drug testing practices across laboratories. The discussion explores how consensus recommendations are developed, why evolving drug trends require continual updates, and how emerging substances such as nitrous oxide create new challenges for law enforcement, laboratories, and expert witnesses. Amanda also reflects on career growth, collaboration within the forensic science community, and the real-world demands of communicating toxicology findings in court. This episode offers a thoughtful look at the intersection of science, policy, and public safety through the perspective of a scientist helping guide the future of impairment testing.

Country Roads (and Emerging Drugs): A Special Episode with Donna Papsun

In this episode of the Impairment Perspectives Podcast, host Joey Jones talks with forensic toxicologist Donna Papsun of NMS Labs about emerging drug trends, novel psychoactive substances, and the public health role of forensic toxicology. Their conversation covers kratom, synthetic opioids, nitazenes, orphines, designer benzodiazepines, xylazine, lab funding challenges, real-time drug surveillance, and the importance of clear scientific communication. Donna also shares career advice, reflections on mentorship, and insights from nearly two decades in the forensic toxicology field.

Built to Troubleshoot: Cars, Leadership, and Alcohol Testing with David Zimmerman

In this episode of Impairment Perspectives, host Joey Jones talks with David Zimmerman, Assistant Laboratory Director at the Kern Regional Crime Laboratory, about the science and practice behind forensic alcohol testing. David shares his path from chemistry teacher to forensic toxicologist, explains why headspace gas chromatography with flame ionization detection remains a reliable standard in the lab, and discusses troubleshooting, measurement uncertainty, courtroom communication, and the realities of leading a modern toxicology program. The conversation also highlights the hands-on mindset required in forensic science and the importance of clear, practical training for professionals involved in impaired driving cases.

0.05 BAC: Does Lowering the Legal Limit Save Lives, with Amy Berning and Jen Harmon

In this episode of Impairment Perspectives, host Joey Jones is joined by Amy Berning and Jen Harmon for a timely discussion on the science, policy, and real-world implications of lowering the legal BAC limit to 0.05. Drawing on Amy’s 36-year career at NHTSA and Jen’s forensic toxicology expertise, the conversation explores Utah’s 0.05 law, the 2024 Drugs and Human Performance Fact Sheets, impaired driving research, and how data-driven policy can shape the next major shift in traffic safety.

Where Clinical Toxicology Meets Forensic Toxicology with Rob Moore and Rebecca Wood

In this episode of Impairment Perspectives, host Joey Jones speaks with Rob Moore and Rebecca Wood, the clinical scientists behind The Tox Lab podcast. Together, they discuss the evolving world of clinical and forensic toxicology, the rise of emerging synthetic drugs like nitazenes and orphines, and the growing need for advanced testing methods such as high-resolution mass spectrometry. The conversation also explores the challenges of interpreting complex toxicology data, training the next generation of scientists, and bridging the gap between laboratory science, public health, and real-world impairment investigations.
