Forensic Toxicology

Forensic toxicology investigates the intersection of chemistry, biology, and the law. It focuses on the detection and interpretation of drugs, chemicals, and poisons within the context of legal investigations and litigation. By merging sophisticated laboratory applications with pharmacological insights, our scientists provide the clarity needed to navigate complex legal challenges. From assessing impairment in workplace safety to determining the role of substances in postmortem investigations, we turn analytical data into actionable forensic evidence.

Our Forensic Toxicology Consulting Expertise

Intertox, Inc. provides access to seasoned forensic toxicology experts with decades of experience spanning medical examiner offices and high‑stakes litigation. Our consultants bridge the gap between law‑enforcement impairment protocols and the scientific realities of drug pharmacokinetics—how the body processes a substance—and pharmacodynamics—how that substance affects the body. This integrated expertise ensures clear, scientifically grounded guidance in even the most complex cases.


We provide comprehensive support for a diverse range of legal and regulatory matters:


  • Criminal & Civil Litigation: Expert testimony and consultation for grand juries, administrative hearings, and personal injury cases.
  • Human Performance: Evaluating impairment in "under the influence" cases, workplace safety incidents, and  child custody disputes.
  • Postmortem Toxicology: Determining whether      substances were a primary cause or a contributing factor in a death.
  • Laboratory Quality Systems: Technical methodology      evaluation, data analysis, and accreditation compliance to ensure the  integrity of your evidence.


Our experts evaluate the totality of circumstances in every case, utilizing all biological matrices to provide thorough, scientific, and objective findings for our clients.
