Actually a very important question the defense asked regarding methamphetamine and pupil dilation.
The defense attorney asked whether the witness observed constricted or dilated pupils, to which the witness responded that he observed constricted pupils, which is the opposite observation one would make if a patient was under the influence of methamphetamine, thus ruling out methamphetamine as the acting substance at the time of arrival of the EMTs.
It's interesting to note that George Floyd's behavior in the store was one of mania, typical in a case involving methamphetamine. However once officers arrived on the scene George Floyd started nodding off inside his car, a sign of opioid overdose. This also ties into the fact that IIRC it was previously revealed that the percocet tablets Floyd took actually contained both Methamphetamine and Fentanyl.
EDIT: I rewatched the last 25 minute segment prior to the lunch break and found what the female prosecutor was saying. She asked the witness whether he checked the pupils or got the report from his partner on Floyd's pupil size. On both questions he said no, however he did clarify that his partner did say something about the size of Floyd's pupils.
Now this is an interesting question that someone with more knowledge of chemistry should answer. If you consume a mixture of substances (ie meth and fentanyl) are both substances metabolized by the body at the same time? Or does one substance metabolize faster than the other? Because, IIRC I do recall hearing the latter and not the former.
