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 2021 pilot study reported strong initial antinociceptive responses to THC and cannabinolic acid, followed by decreasing responses over subsequent days. The evidence concerns adult male mice and experimental mechanical and thermal tests. The study evaluated two nociceptive domains Mechanical and thermal responses were assessed after systemic intraperitoneal administration. Those…
A 2001 mouse study found different opioid- and cannabinoid-receptor protein patterns across midbrain and spinal cord after short-term THC–morphine treatment. A statement about total receptor change would obscure those tissue-specific comparisons. The comparison included separate treatment groups Investigators assessed THC, morphine and their combination using Western blot measurements. Opioid-receptor protein…
A 2003 study found that selected kinase inhibitors reversed THC antinociceptive tolerance while others did not. One higher-dose intervention reduced THC's acute antinociceptive effect, illustrating a different outcome from reversing tolerance. The panel included useful negatives The study tested interventions directed at several kinases. Some did not affect tolerance under…
