Forensic toxicologists analyze biological specimens to detect and quantify drugs, alcohol, and poisons, evaluating laboratory methodology, chain of custody, and the interpretation of toxicological findings in criminal and civil cases 1. These experts are essential in DUI prosecutions and defenses, where NHTSA Standardized Field Sobriety Testing protocols provide the field evidence that toxicology results must corroborate or contradict 2. In death investigations, forensic toxicologists must account for postmortem redistribution — the well-documented shift in drug concentrations after death that can misrepresent antemortem levels if improperly interpreted 3. Board certification by the American Board of Forensic Toxicology (ABFT), which has certified forensic toxicologists since 1975, is the recognized credential for demonstrating competency in this field 4. Professional membership in the Society of Forensic Toxicologists (SOFT) reflects active engagement in the discipline's scientific standards and ethical practice 5.
Postmortem redistribution can cause drug concentrations measured at autopsy to differ substantially from levels present at the time of death, making specimen site selection and expert interpretation critical in any drug-related fatality case.

FAQ
Forensic toxicologists are laboratory scientists who analyze biological specimens for drugs and poisons using analytical chemistry methods. Medical toxicologists are physicians who treat poisoned patients and provide clinical opinions on causation. Forensic toxicologists focus on the analytical evidence, while medical toxicologists address clinical effects and outcomes.
Forensic toxicologists are needed in DUI/DWI cases to challenge or support blood and breath testing, drug-related death investigations, workplace drug testing disputes, poisoning cases, and any litigation where the presence, quantity, or effects of drugs, alcohol, or chemicals in the body are at issue.
In general, forensic expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic casework, academic qualifications, certifications, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
