Lithium remains one of the most effective and enduring treatments in psychiatry, particularly for bipolar disorder. Its ability to reduce suicide risk and stabilize mood is unmatched in many respects. However, lithium’s narrow therapeutic index and complex pharmacokinetics create a well-recognized risk of toxicity. While most clinicians are familiar with acute lithium toxicity, fewer appreciate a rare but devastating complication: SILENT syndrome—Syndrome of Irreversible Lith

Acetaminophen, widely marketed as Tylenol, is one of the most commonly used over-the-counter analgesics and antipyretics in the world. Its accessibility and perceived safety have made it a household staple. However, acetaminophen is also the leading cause of acute liver failure in the United States, a distinction that underscores a critical paradox in modern pharmacology. Whether through a single intentional overdose or repeated supratherapeutic ingestion, acetaminophen toxic

What It Is, Why Officials Were Concerned, and What Happens If You're Exposed

Plants are often perceived as safe, natural, and inherently benign. In reality, the botanical world contains some of the most potent toxins known—agents that have shaped human history as poisons, medicines, and ritual substances. Today, plant toxicity remains highly relevant, with exposures ranging from accidental pediatric ingestions to intentional self-harm, herbal supplement misuse, and foraging errors. For clinicians and first responders, recognizing plant-based toxidrome

Alberto Augsten, PharmD, MS, BCPP, DABAT | Augsten Consulting, LLC A new research letter in JAMA Pediatrics (Kleinman et al., March 2026) compared buprenorphine-naloxone and methadone for opioid overdose prevention in Ontario youths aged 15 to 24 with opioid use disorder (OUD). The findings, and the published responses they generated, carry direct implications for cases involving adolescent overdose, prescribing-standard disputes, and medical negligence claims tied to substan

“Poppers” are widely perceived as harmless recreational agents—marketed as room deodorizers, leather cleaners, or liquid incense. In reality, these products contain alkyl nitrites, a class of volatile vasodilators that can produce rapid physiologic effects and, in certain contexts, life-threatening toxicity. While often used for brief euphoria or smooth muscle relaxation, the risks are frequently underestimated by both users and clinicians. What Are Poppers? Poppers typically

Snake venom is among the most pharmacologically complex substances produced by any living organism. It is a biochemical weapon refined over millions of years of evolution — a mixture of proteins, enzymes, peptides, and small molecules capable of immobilising prey, defending against predators, and in some cases, beginning the digestive process before a meal is even swallowed. For toxicologists, pharmacologists, and environmental health scientists, snake venom represents one of

In the mid-twentieth century, Minamata Bay in Japan's Kumamoto Prefecture became the site of one of the worst environmental health disasters in history — a tragedy that would come to symbolize the catastrophic consequences of industrial mercury pollution and the failure of governments and corporations to protect human life. The Source of the Contamination From the late 1940s through the 1950s, the Chisso Corporation discharged methylmercury-laden wastewater directly into Mina

It blooms in shades of white, yellow, and peach — hanging like soft bells from sprawling branches. In South Florida yards, along fences, and in neighborhood gardens, Brugmansia — commonly known as Angel's Trumpet — is a familiar and stunning sight. But behind that beauty is one of the most toxic plants accessible to children in the region, and most families have no idea. What Is Angel's Trumpet? Angel's Trumpet (Brugmansia spp.) is a flowering plant native to South America th

Few substances in history have earned as fearsome a reputation as arsenic. Known for centuries as the "king of poisons" and the "poison of kings," arsenic occupies a uniquely sinister place in the story of human civilization. Its tasteless, odorless, and nearly colorless properties when dissolved made it the ideal instrument of covert murder for hundreds of years, and its legacy has shaped the development of modern forensic toxicology. What Is Arsenic? Arsenic is a naturally

Stimulant overdoses from cocaine and methamphetamine represent a growing component of the overdose epidemic, distinct from opioid-related deaths. These drugs cause overdose through entirely different mechanisms—via cardiovascular and neurological pathways—making them particularly deadly when combined with other substances. Understanding Stimulant Pharmacology Cocaine and methamphetamine are psychostimulants that increase dopamine, norepinephrine, and serotonin in the brain, c

Benzodiazepines and barbiturates are classes of medications designed to treat anxiety, insomnia, and seizures. However, their high potential for abuse, dependency, and overdose has made them significant contributors to drug-related mortality. This is especially true when these substances are combined with other central nervous system depressants like opioids and alcohol. The Role of Benzodiazepines and Barbiturates in Treatment Benzodiazepines, commonly referred to as "benzos

The opioid crisis represents one of the most devastating public health emergencies in modern history. Prescription opioids and illicit opioids like fentanyl have become the leading cause of overdose deaths across North America, fundamentally transforming treatment approaches and social policy worldwide. Understanding Opioids and Their Mechanism Opioids are a class of drugs that bind to opioid receptors in the brain, reducing pain perception and creating euphoric effects. From

Driving under the influence (DUI) cases often hinge on complex scientific evidence. Among the critical experts in these cases are forensic toxicologists. Their role in toxicology analysis for DUI is essential to understanding the presence and impact of substances in the body. This article explores the importance of forensic toxicologists in DUI defense cases, the nature of toxicology analysis, and how their expertise supports legal professionals and healthcare organizations.

Dopamine, often called the "motivation molecule," plays a crucial role in our ability to feel driven, find pleasure in activities, and maintain focus. When dopamine levels are disrupted, as often occurs in depression, the consequences can be profound. This article explores the neurobiology of dopamine, how depression affects dopamine function, and what this means for motivation and engagement with life. Understanding Dopamine Dopamine is a neurotransmitter—a chemical messenge

The vagus nerve, the longest cranial nerve in the body, has recently garnered significant attention for its role in anxiety and stress regulation. Often called the "wandering nerve" because it extends from the brain all the way to the gut, the vagus nerve is a crucial component of the parasympathetic nervous system, which governs the body's "rest and digest" functions. Understanding how to stimulate vagal tone—the strength and responsiveness of the vagus nerve—offers a powerf

Every few years, a substance emerges from the fringes of medicine and captures the attention of patients, families, and policymakers desperate for answers to the opioid crisis. Right now, that substance is ibogaine. And while hope is understandable — it's not enough. What Is Ibogaine? Ibogaine is a naturally derived psychoactive compound from Tabernanthe iboga that has been studied for its possible effects on addiction. Some individuals report significant reductions in opioid

Panic disorder affects roughly 2-3% of the population and is characterized by recurrent, unexpected panic attacks followed by intense fear of future attacks. What distinguishes panic disorder from occasional anxiety is the severity, unpredictability, and the profound impact on daily functioning. This article explores panic disorder's symptoms, neurobiological basis, and evidence-based treatments. What Is a Panic Attack? A panic attack is an abrupt surge of intense fear accomp
