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.

Deleting the serotonin 5-HT2A receptor reduced a THC-related memory effect in mice at 3 mg/kg but not at 10 mg/kg. The dose-dependent result limits claims that removing one receptor universally prevents THC’s cognitive effects. Mechanistic animal and cell research Researchers compared mice lacking 5-HT2A receptors with wild-type mice. Cell experiments,…

Observed THC capsule dosing and THC/CBD mouth-spray dosing produced very different saliva patterns. A test used to monitor treatment must be matched to how the medicine enters the body. Five conditions in fourteen people Fourteen cannabis users completed randomized sessions with low- and higher-dose swallowed THC, low- and higher-dose THC/CBD…
A ratio near one can mislead when its numerator and denominator use different units. In a controlled cannabis study, oral-fluid-to-plasma THCCOOH ratios were reported in ng/µg because oral-fluid metabolite concentrations were much lower. Paired specimens under controlled dosing Eleven daily cannabis smokers resided on a research unit for 51 days….
