Okorie Okorocha, J.D., M.S., M.S. • Attorney • Forensic Toxicologist • Expert Witness
Serious representation when medicine, drugs, alcohol, toxicology, or complex scientific evidence can determine the outcome.
When the case depends on the science, your lawyer should understand the science.
Forensic toxicology expert witness
Drug and alcohol evidence can appear definitive while leaving critical scientific questions unresolved. Forensic-toxicology analysis may address specimen integrity, analytical methodology, pharmacology, claimed impairment, measurement uncertainty, laboratory limitations, and whether the stated conclusion follows from the available data.
Where science meets the courtroom
Drug and alcohol evidence can look definitive while leaving critical questions unanswered. Analysis may require review of specimen integrity, analytical methodology, pharmacology, impairment, measurement uncertainty, laboratory limitations, and whether the conclusion actually follows from the data.
Serious-felony matters
The criminal-defense practice is limited to serious felony matters, including murder or manslaughter, sex-crime, and white-collar allegations. Forensic, toxicological, medical, and other scientific evidence is evaluated when relevant.
Civil representation
Personal injury, wrongful death, catastrophic injury, employment, and civil-rights matters can turn on medical causation, toxicology, drug or alcohol evidence, laboratory findings, and competing expert opinions.
Board and State Bar matters
Defense of attorneys, physicians, nurses, dentists, pharmacists, and other California licensees facing complaints, investigations, Accusations, disciplinary hearings, probation, or reinstatement.

A rat imaging study found distinct THC, CBD and combination patterns in connectivity and blood flow. The mixture moderated some THC-associated findings, but the experiment does not establish a human protective ratio or a validated impairment test. The exposures were not identical across arms Adult male rats received injected THC,…

Comparable peak circulating THC did not produce identical brain and metabolite profiles after injected versus inhaled THC in rats. Matching one parent-drug concentration therefore did not make the two routes biologically interchangeable. A direct route comparison Adult male and female Sprague–Dawley rats received intraperitoneal THC or a 15-minute inhalation exposure….

The analyte in a laboratory method matters more than shorthand in its title. A paper titled as urinary THC quantification describes a confirmatory method for THC-COOH, the carboxy metabolite. That is not a measurement of active parent THC or contemporaneous impairment. What the method measured The investigators developed solid-phase extraction…
