    Cat and Mouse: How Toxicologists Chase Ever-Evolving Designer Drugs

    Send us Fan Mail In this compelling episode, Dr. Kayla Ellefsen—Deputy Chief Toxicologist at the Travis County Medical Examiner’s Office in Austin, Texas, United States-offers a rare look into the science of forensic toxicology and its critical role in death investigations. She dismantles Hollywood myths about quick test results and flashy labs, revealing the meticulous process toxicologists follow to identify substances in postmortem samples and determine their role in a person's death. The conversation takes a deeper turn into one of the most urgent challenges facing toxicologists today: Novel Psychoactive Substances (NPS). These synthetic compounds are designed to imitate known illicit drugs while evading laws and standard detection methods. Dr. Ellefsen describes the evolving “cat-and-mouse” game between underground chemists and forensic labs, and how advanced tools like high-resolution mass spectrometry are crucial. A particularly alarming trend she highlights is the rise of bromazolam, a designer benzodiazepine. Even more concerning is the emergence of “benzodope”—the deadly mix of benzodiazepines and synthetic opioids. Dr. Ellefsen closes with a strong message: researchers must share data on NPS to build a clearer picture of the threat and support the development of harm reduction tools. Whether you're curious about forensic science, concerned about public health, or trying to understand today’s shifting drug landscape, this episode delivers critical insight into a field on the front lines of modern substance misuse.

    Demystifying Forensic Medicine: Tales from the Morgue

    Send us Fan Mail Join us on the Analytical Zen Podcast  for an interview with Professor Christopher Milroy, a forensic pathologist and professor based in Ottawa, Canada. Professor Milroy earned his medical degree from the University of Liverpool and trained in pathology in Liverpool, Bristol and London before specializing in forensic pathology in Sheffield. From 1990 to 2008, he worked as a forensic pathologist and professor of forensic pathology in Sheffield, before moving to Ottawa in 2008. In addition to his medical qualifications, Professor Milroy holds two law degrees from the University of London. He is a fellow of the Royal College of Pathologists, the Royal College of Physicians of Canada and the Faculty of Forensic and Legal Medicine. Throughout his career, he has performed thousands of autopsies and served as an expert witness in hundreds of murder trials across multiple countries. He has also provided expert testimony in public inquiries in both Canada and Ireland. Professor Milroy's research interests include homicide, suicides, drug-related deaths, post-mortem toxicology, biochemistry and the history of forensic medicine. In 2023, he was honoured with the title of Officer of the Order of the British Empire (OBE) in the King’s Birthday Honours. Join the conversation at The Analytical Zen Podcast!
