Very misleading, considering the testimony of the forensic toxicologist who tested George's blood. A forensic toxicologist at the laboratory that tested George Floyd’s blood said it was common for intoxicated driving suspects who used fentanyl to have higher levels of the drug in their systems than Mr. Floyd did when he died. Of more than 2,300 blood samples from intoxicated drivers that N.M.S. Labs tested last year — all of which were in cases where the driver survived and tested positive for fentanyl — about a quarter of the people had fentanyl levels that were the same or higher than Mr. Floyd’s, Dr. Isenschmid said. Methamphetamine was also found in Mr. Floyd’s system, though Dr. Isenschmid said the levels were so low that it likely had no intoxicating effect. A toxicologist’s testimony challenged claims by Derek Chauvin’s lawyer that George Floyd overdosed on fentanyl.
