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.

The route of cannabis use changes the timing of both blood THC and observed effects. Controlled research shows delayed effects after edibles and rapidly falling blood THC after vaporization, even while performance effects continue.
The common claim that cannabis necessarily causes dilated pupils is too simple. A controlled pupillography study found reduced pupil size and a slower, less pronounced response to light after intravenous THC.
A postmortem ethanol number does not explain where the specimen came from, what happened before analysis, or whether some ethanol formed after death. A 2024 scientific review identifies the evidence needed to evaluate those questions.
