Forensic Toxicology Resources
This resource hub connects attorneys, experts, students, and readers with forensic toxicology guides, litigation checklists, scientific standards, and official legal materials. Use the case-review resources when drug, alcohol, medication, poisoning, laboratory testing, impairment, or other scientific evidence may affect a legal outcome.
Forensic toxicology case-review guides
- Forensic Toxicology Case Review Checklist: records to request for specimen identity, chain of custody, raw data, calibration, controls, validation, and interpretation.
- How to Review a Toxicology Laboratory Packet: a step-by-step framework for tracing a reported result through the complete laboratory record.
- Positive Drug Test vs. Impairment: what a positive result can establish and why impairment, timing, dose, and causation require additional evidence.
- Rule 702 and Forensic Toxicology Expert Testimony: scientific issues involving qualifications, facts and data, methods, application, and opinion limits.

Case-specific assistance
General resources cannot determine what a laboratory result means in a particular case. The analysis may depend on the specimen, collection history, analytical method, complete raw data, medical record, timeline, observations, and the legal question presented.
