George Floyd had enough fentanyl in his system to kill 3 people.

Not really. It's the combo of fentanyl and morphine and the other stuff that went over the top. The normal lethal dose for fentanyl is 2mg total dose and he had a blood level of 11ng/ml. Assuming 5 liters of blood, he took 55ug of fentanyl which is about 1/20th of the lethal dose. It is enough for anesthesia though. And people have died from as little as 7ng/ml if they were also taking morphine. So he definitely ODed, but be careful saying it was just fentanyl because people can prove you wrong.

According to the CDC levels of fentanyl above 3ng/ml are often fatal. Levels above 9.5 appear to always be fatal. Georgie’s were 11. While the cocktail of drugs in his system did not help, that much fentanyl was more than enough to kill him.
