Relevant evidence can include hospital and emergency medical records, toxicology results, fentanyl and norfentanyl findings, autopsy reports, scene-investigation records, prescription or pharmacy information, naloxone administration records, laboratory methods, and information concerning other drugs or alcohol. The importance of each source depends on whether the matter involves a nonfatal overdose, a death investigation, prescribed fentanyl, or suspected illicit fentanyl exposure. Fentanyl is a potent synthetic opioid, and CDC distinguishes pharmaceutical fentanyl from illegally manufactured fentanyl when describing overdose risk and exposure.
Not reliably. Fentanyl concentrations should be interpreted together with the circumstances, toxicology findings, medical history, autopsy evidence, specimen information, and other substances detected. Published forensic toxicology research has found substantial overlap in postmortem fentanyl concentrations and cautions against using a blood concentration alone to infer the dose received or determine cause of death. Factors such as tolerance, metabolism, postmortem redistribution, specimen source, and co-intoxicants can affect interpretation.
Co-exposures can materially affect interpretation because opioids may be taken with other depressants, stimulants, prescription medications, or illicit substances. The expert can examine which substances were detected, their timing and concentrations where interpretable, known pharmacologic effects, and whether the overall clinical or postmortem evidence supports a combined intoxication rather than fentanyl acting alone. SAMHSA notes that mixing opioids with other substances, including certain sedating medications or alcohol, can increase overdose risk.
Naloxone is an opioid antagonist used to reverse opioid overdose, including fentanyl overdose. Records concerning when naloxone was administered, the dose or doses given, respiratory status, response, resuscitation, and subsequent medical treatment may therefore provide important evidence about the event. CDC notes that more than one dose can sometimes be required when potent opioids such as fentanyl are involved. A response to naloxone can be clinically informative, but it should be interpreted with the rest of the record rather than treated as stand-alone proof of the precise opioid, dose, or cause.
Prepares clear, well-supported expert reports outlining methodology, analysis, findings, and opinions.
Provide Deposition Testimony
Explains findings and opinions under oath and responds to questioning during deposition testimony.
Testify in Court
Presents specialized findings and opinions clearly to judges, juries, arbitrators, or other decision-makers.
The disputed question should determine the expert discipline. An expert with specific experience in fentanyl exposure and overdose may be appropriate when fentanyl-related evidence is central to the matter. Medical Toxicology may be especially relevant to clinical poisoning, overdose treatment, mixed exposures, or toxic effects. Forensic Toxicology may be more appropriate when the principal issue concerns analytical testing, drug concentrations, postmortem specimens, or interpretation of toxicology findings. Addiction Medicine may be appropriate when substance use disorder or treatment is the principal issue. For fatal cases, interpretation may also require forensic pathology or other appropriate medical expertise when cause of death, autopsy findings, or competing disease processes are disputed.
