Suicide by a Novel Toxic Substance: A Scoping Review
Summary
A novel suicide method using a toxic substance is a growing global concern. Understanding individual profiles and online access is crucial for effective suicide prevention strategies.
Area of Science:
- Public Health
- Toxicology
- Epidemiology
Background:
- A novel suicide method involving a toxic substance has emerged, raising international concern.
- The arrest of Kenneth Law highlighted the need for better surveillance and understanding of individuals using this method.
- Effective suicide prevention requires improved knowledge of those who adopt this specific self-poisoning technique.
Purpose of the Study:
- To review and summarize existing epidemiological evidence on suicide attempts and deaths linked to this specific toxic substance.
- To inform suicide prevention efforts by analyzing trends and characteristics of individuals involved in self-poisoning incidents.
- To provide a comprehensive overview of the current state of knowledge regarding this emerging suicide method.
Main Methods:
- Systematic scoping review following PRISMA-ScR guidelines.
- Literature search conducted in MEDLINE, EMBASE, and SCOPUS up to March 16, 2026.
- Inclusion of case reports, case series, and research articles detailing suicide attempts or deaths involving the substance.
Main Results:
- Sixty-seven studies were included, predominantly case reports and case series.
- A significant number of cases indicated that individuals sourced the substance online.
- The review identified a rising global trend in suicides involving this substance.
Conclusions:
- A global increase in suicides using this toxic substance necessitates a targeted public health response.
- Addressing the online supply chain and improving surveillance/coding accuracy are key recommendations.
- Enhancing clinician/investigator awareness and coordinating regulatory actions are vital for restricting access.

01:26Pharmaceutical Poisoning: Potential Scenarios
Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...
01:30Toxidromes: Clinical Features
Toxidromes are specific patterns of symptoms resulting from toxic substance exposure. They help in the identification and treatment of poisoning. The symptoms of each toxidrome group indicate poisoning by a certain class of chemicals or drugs.1. Sympathomimetic: Stimulates the sympathetic nervous system. Symptoms include agitation, increased heart rate (HR), blood pressure (BP), respiratory rate (RR), temperature, and pupil size. Drugs like cocaine and amphetamines, along with tremors and...
01:26Pharmaceutical Poisoning: Treatment Strategies
Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...
01:24Drug Toxicity: Risk factors
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
01:00Drug Toxicity: Overview
Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...
