Challenging Toxicology Evidence in Criminal Cases
Toxicology evidence is frequently used in criminal prosecutions involving alleged intoxication, overdose deaths, impaired driving, and homicide investigations. However, toxicology findings are not always straightforward and may be subject to scientific interpretation disputes.
At the Law Office of Nicholas Frye, we carefully review laboratory procedures, toxicology findings, and expert conclusions to identify weaknesses and inconsistencies in the prosecution’s evidence.
Toxicology Issues We Examine
We review:
- Blood and urine testing procedures
- Drug concentration interpretation
- Alcohol testing accuracy
- Laboratory handling procedures

- Chain of custody concerns
- False positives and contamination issues
- Independent laboratory review
- Expert testimony reliability
Complex Scientific Issues Require Careful Review
Toxicology findings may not always establish impairment, causation, or criminal responsibility. Scientific interpretation often requires careful analysis and expert review.
Attorney Nicholas Frye aggressively examines forensic toxicology evidence and challenges unsupported conclusions whenever appropriate.
