TOXICS 2023; 11:506. [PMID: 37368606 DOI: 10.3390/toxics11060506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 05/30/2023] [Accepted: 05/31/2023] [Indexed: 06/29/2023]
Abstract
Interpreting fatalities involving khat is challenging due to a lack of data on cathinone and cathine reference concentrations in postmortem tissues. This study investigated the autopsy findings and toxicological results of fatalities involving khat in Saudi Arabia's Jazan region from 1 January 2018 to 31 December 2021. All confirmed cathine and cathinone results in postmortem blood, urine, brain, liver, kidney, and stomach samples were recorded and analyzed. Autopsy findings and the manner and cause of death of the deceased were assessed. Saudi Arabia's Forensic Medicine Center investigated 651 fatality cases over four years. Thirty postmortem samples were positive for khat's active constituents, cathinone and cathine. The percentage of fatalities involving khat was 3% in 2018 and 2019 and increased from 4% in 2020 to 9% in 2021, when compared with all fatal cases. They were all males ranging in age from 23 to 45. Firearm injuries (10 cases), hanging (7 cases), road traffic accident (2 cases), head injury (2 cases), stab wounds (2 cases), poisoning (2 cases), unknown (2 cases), ischemic heart disease (1 case), brain tumor (1 case), and choking (1 case) were responsible for the deaths. In total, 57% of the postmortem samples tested positive for khat only, while 43% tested positive for khat with other drugs. Amphetamine is the drug most frequently involved. The average cathinone and cathine concentrations were 85 and 486 ng/mL in the blood, 69 and 682 ng/mL in the brain, 64 and 635 ng/mL in the liver, and 43 and 758 ng/mL in the kidneys, respectively. The 10th-90th percentiles of blood concentrations of cathinone and cathine were 18-218 ng/mL and 222-843 ng/mL, respectively. These findings show that 90% of fatalities involving khat had cathinone concentrations greater than 18 ng/mL and cathine concentrations greater than 222 ng/mL. According to the cause of death, homicide was the most common fatality involving khat alone (77%). More research is required, especially toxicological and autopsy findings, to determine the involvement of khat in crimes and fatalities. This study may help forensic scientists and toxicologists investigate fatalities involving khat.

Jones AW. Review of Caffeine-Related Fatalities along with Postmortem Blood Concentrations in 51 Poisoning Deaths. J Anal Toxicol 2017; 41:167-172. [PMID: 28334840 DOI: 10.1093/jat/bkx011] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2016] [Indexed: 11/15/2022] Open
Abstract
Publications reporting concentrations of caffeine in postmortem blood were reviewed if the cause of death was attributed to overdosing (poisoning) with drugs. Age and gender of the deceased, the manner of death (accident, suicide or undetermined) and types of co-ingested drugs were evaluated in relation to the concentrations of caffeine in blood (N = 51). The mean age (±SD) of the victims was 39 ± 17.8 years (range 18-84 years) and most were female (N = 31 or 61%). The difference in mean age of males (42 ± 17.2 years) and females (37 ± 18.3 years) was not statistically significant (t = 0.811, P = 0.421). The mean (±SD), median and range of caffeine concentrations in postmortem blood were 187 ± 96 mg/L (180 mg/L) and 33-567 mg/L, respectively. The median concentration of caffeine in males (161 mg/L) was not significantly different from that of females (182 mg/L), z = 1.18, P = 0.235. There was no correlation between the age of the deceased and the concentration of caffeine in postmortem blood (R2 = 0.026, P > 0.05). Manner of death was classified as suicide in 51% of cases (median blood-caffeine 185 mg/L), accidental in 16% (median 183 mg/L) or undetermined in 33% (median 113 mg/L). The median concentration of caffeine in blood was lower when manner of death was undetermined compared with suicide or accidental (P = 0.023). Although other drugs, including ethanol, antidepressants, antipsychotics, benzodiazepines and/or ephedrine, were often identified in postmortem blood, the predominant psychoactive substance was caffeine. The deceased had ingested caffeine in tablet or powder form and it does not seem likely that toxic concentrations of caffeine can be achieved from over-consumption of caffeinated beverages alone.

Abstract
With training in pharmacology, a pharmacologist has an expert knowledge as well as working experience in the subjects of therapeutics, pharmacokinetics, and toxicology along with exposure to subjects such as forensic medicine during the medical education. All these knowledge domains can be applied and act as an interface to the forensic situations. The skills and expertise of a forensic pharmacologist can be useful in a large and diverse number of legal cases. With an ever increasing incidence of criminal and civil cases in India, the development and inclusion of forensic pharmacologist in the judicial system of India are the need of the hour. The research in pharmacology has witnessed great technological advancement that allows it to expand its scope beyond the domain of therapeutics, thus enabling Indian pharmacologists to explore the niche area of Forensic Pharmacology. Differing pharmacokinetics and pharmacodynamics of drugs in living and dead, drug interactions, abuse of drugs, personal injury or death due to drug exposure leading to medico-legal issues, environmental exposure to chemicals, and doping and forensic pharmacovigilance are the diverse aspects of Forensic Pharmacology.

Abstract
Forensic science is the acquisition, analysis, and application of scientific data to provide the legal system with answers to questions of interest. Pharmacy fills a forensic niche. Most pharmacists work in forensics part-time at their regular job or moonlight. A rare few work full-time. Most often, forensic pharmacists work as consultants to attorneys, claims adjustors, detectives/investigators, and other forensic specialists. These pharmacists review cases much like a clinical pharmacist or pharmacy manager would review a clinical challenge or administrative problem, but with an eye to the specific legal issues. Pharmacists' expert testimony has traditionally been offered in either therapeutics and human pharmacology or pharmacy practice. New specialty areas include drug-induced violence and death investigations. Deaths in long-term care facilities constitute their own category, and every state has its own approach. The law and science consider evidence quite differently, and sometimes, final verdicts surprise scientists.

Abstract
Forensic pharmacy is application of the sciences of drugs to legal issues. Forensic pharmacists engage in work relating to litigation, the regulatory process, and the criminal justice system. Forensic pharmacy overlaps with many other forensic fields. Pharmacists hold a variety of positions with local, state, and federal governments. Many pharmacists do freelance work as forensic litigation consultants. A forensic pharmacist can be a valuable resource in legal cases relating to malpractice, adverse drug reactions, drunk and drugged driving, health care fraud, poisoning, and numerous other types of civil and criminal cases.
