Samples will be obtained from cadavers that have been donated and properly consented for the purpose of scientific research, and which have been embalmed by those medical schools. All three fluids have been described comprehensively in the anatomical literature, as well as being flagged in the forensic literature, and there is, thus, convincing primary evidence justifying their examination in this study.įor the study, which will form the first part of a PhD project, samples of vitreous humour, synovial fluid and cerebrospinal fluid will be obtained from UK university medical school anatomy departments. This study, therefore, seeks to analyse vitreous humour from the eye, synovial fluid from the knee joints and cerebrospinal fluid from the spinal column. The purpose of this study is to test three particular fluids in the human body that do not receive a direct blood supply, in the expectation that they will not be contaminated during embalming, a process that involves the injection of preservative chemicals into the circulatory system of the body. Although it is usually still possible to identify the presence of drugs, the constituent chemicals in embalming fluids affect not only the detection but also the rate of decay of the majority of both pharmaceutical and illicit drugs in blood and many other bodily tissues, making forensic evidence unsafe and, therefore, usually inadmissible in courts of law. ![]() In the case of deaths abroad, bodies are embalmed prior to repatriation to the UK, and consequently before detailed investigations into the cause of death can be undertaken on British soil. 'Wet' The cigarettes are sold for about 20 a piece. Drug users have taken to combining embalming fluid with phencyclidine (PCP), a known hallucinogen, and coating their marijuana cigarettes with the substance. The fluid is a combination of water and preservative chemical, such as formaldehyde. ![]() In the United Kingdom, the problem is encountered most frequently in the bodies of nationals nationals dying abroad, where drug involvement is suspected to have contributed to the death. The most common method is to dip a tobacco or marijuana cigarette in the embalming fluid, then dry it before smoking it. Embalming fluid is injected into the arteries via a tube connected to an embalming machine. The embalming of human bodies creates significant difficulties for forensic toxicologists, pathologists and coroners.
