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

A laboratory can quantify total drug in plasma while struggling to quantify the much smaller unbound portion. That difference can determine whether a pharmacokinetic study answers its question. A result reported as not statistically significant does not resolve the question when the measurements are too limited to detect a meaningful…

A medication can be associated with a different drug response because of the condition it was prescribed to treat. That possibility matters when interpreting a concentration-response model as evidence of a pharmacodynamic interaction. Franken and colleagues examined this problem in a study of midazolam sedation in terminally ill adults. Their…

A cannabinoid detected after dosing stops is evidence of analytical persistence. It does not, by itself, establish an exact elimination half-life, the time of the last dose or a universal date when another person’s sample will test negative. A controlled study by Wolinsky and colleagues helps explain the distinction. Published…
