Poisons and Drugs Used in Homicidal Poisoning: A Systematic Review

Open access
Soltaninejad, Kambiz·2023·International Journal of Forensic Sciences

Abstract

Homicidal poisoning defined as the application of toxic agents by a person to kill human beings. Historically, some conventional homicidal poisons were including arsenic, cyanide, mercury, strychnine, aconite and atropine. In general, homicidal poisonings are among the least frequently detected crimes and difficult to establish, across the world. Lack of suspicion of this type of poisoning and clinical presentations in this poisoning are often misdiagnosed as natural disease, especially if the crime is occurred in a hospital setting are the limitations for detection of homicidal poisonings. The aim of this article is to review of drugs and poisons used in recently reported homicidal poisoning cases. The results showed that the contemporary poisons and drugs used in homicidal poisonings are based in combinations of old and well-described poisons and drugs and natural or synthetic drugs and poisons from the group of organophosphorus agents, tetrodotoxin, radioactive substances and polydrug pattern of antipsychotics with antidepressants and sedativehypnotics. Forensic autopsy and postmortem histopathological and toxicological analysis have a critical role in investigation on homicidal poisoning fatal cases. The sophisticated instrumental analysis (usually using tandem mass spectrometry) can be used for toxicological analysis of trace levels of drugs and poisons in routine and alternative samples in the victims of homicidal poisoning.

TL;DR

This systematic review of 38 papers reporting 81 homicidal poisoning cases from January 1, 2010 to September 30, 2023 found that contemporary agents combine old poisons and drugs with organophosphorus agents, tetrodotoxin, radioactive substances, and polydrug antipsychotic/antidepressant/sedative-hypnotic patterns. Forensic autopsy, postmortem histopathology, and toxicological analysis—often using tandem mass spectrometry—are critical for investigating fatal homicidal poisoning.

Key findings

  • Among 81 cases, 40 (49.38%) were male and 41 (50.62%) female; age was specified in only 50 cases, with a mean of 39.75 years (range: one month–95 years), and the most impacted group was ≤50 years old (68%). There were 47 (58.02%) fatal cases and 34 (41.98%) survivors.
  • The most common route was oral [61 (75.30%)], followed by injection [9 (11.11%); intravenous 5, subcutaneous 3, intraperitoneal 1], dermal [4 (4.94%)], inhalation [2 (2.59%)], and envenomation [3 (3.70%)]; simultaneous dermal plus injection and oral plus dermal exposure were reported in two cases.
  • By number of victims, arsenic was most frequent (14; 17.28%), followed by thallium (11; 13.58%), paraquat (5; 6.18%), and carbofuran (5; 6.18%); polydrug poisoning including benzodiazepines, Z-drugs, neuroleptics, antidepressants, and analgesics accounted for 16 victims (19.75%). Pharmaceutical agents were reported in 9 articles with 22 poisoned cases and 16 (72.2%) fatalities, and a polydrug pattern was observed in 17 (20.98%) victims.
  • Known offenders were family members in 20 (45.45%) cases, criminals in 19 (43.20%), victim’s girl- or boyfriend in 2 (4.54%), colleagues in 2 (4.54%), and a caregiver in 1 (2.27%).

Methods

  • PRISMA-guided systematic review searching PubMed and Google Scholar with “Homicidal poisoning” OR “Criminal poisoning” for articles from January 1, 2010 to September 30, 2023 describing human homicidal poisoning cases.
  • Inclusion covered all article types describing homicidal poisoning, including forensic-based studies and reports with clinical presentations, autopsy findings, and postmortem histopathological and toxicological analysis; exclusions were insufficient data, no toxicological analysis data, undetected poisonous agent, and non-English publications.
  • Screening identified 302 publications; after removing 162 duplicates/ineligible records, 140 were screened, 89 excluded after title/abstract review, 51 full texts reviewed, 13 further excluded, leaving 38 papers. Extracted data included victim number, age, gender, exposure route, poison name, vehicle, offender identity/relationship, clinical signs, outcome, and forensic autopsy/toxicological/histopathological findings.

Limitations

  • The paper states that homicidal poisonings are rare, poorly described, among the least frequently detected crimes, and difficult to establish worldwide; lack of suspicion and clinical presentations often misdiagnosed as natural disease—especially in hospital settings—limit detection.
  • The paper states that non-English publications were excluded and that articles with insufficient data, no toxicological analysis data, or undetected poisonous agent were excluded.
  • Evident from the text: age was specified in only 50 of 81 cases; some included cases lacked postmortem toxicology or quantitative analysis (e.g., the cyanide case had no quantitative analysis, and one paraquat case had no postmortem toxicology performed), and the review synthesizes heterogeneous case reports without a described formal risk-of-bias or quality appraisal.

    Toxicity data from animal studies (e.g., mouse LD50) are relevant to human homicidal poisoning risk.

    “The oral LD50 in mice as 334 μg/kg.TTX is even more dangerous if administered intravenously; the amount needed to reach a lethal dose by injection is 8 μg/ kg in mice [72].”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Novichok victim count omits a named victim

    Minor

    Table 2 counts two Novichok victims, but the paper names Sergei Skripal, Yulia Skripal, and Alexei Navalny as victims.

  • Inhalation percentage does not match the case total

    Minor

    Two of the 81 cases represent 2.47%, not 2.59%.

    Reported 2.59 · recomputed 2.469136

  • Arsenic is described as one episode but tabulated as two

    Minor

    The discussion says arsenic had one reported homicidal poisoning episode, while Table 2 lists two.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-23.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-23.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
