The George Floyd autopsy states he had 19 ng/mL of Meth in his blood. Reference sources say that a fatal dose of Meth begins around 2.5 mg/L. So - I did a two step conversion. First - 2.5 mg would be 2,500,000 ng/L. Second - 2,500,000 ng/L would be 2,500 ng/mL. So - a fatal dose of Meth would be around 2,500 ng/mL, which is more than 100 times the level George Floyd had in his blood. Is that correct? Thanks again.
Correct, a little over 100 times.
Your math appears to be correct.
A fatal dose may not be the “therapeutic dose”, the level at which it has an effect.
19 ng per mL =
19000 ng per L =
.019 mg per L
From what little I can find on-line, it appears that the level in his blood was about 1% of a fatal dose, and about 10% of a “therapeutic” dose, meaning if he was intoxicated, it was only mildly so. He probably took some the day before.
Why only mention the meth.
Your math looks correct. However, the figures for a fatal dose are for a single substance. When multiple substances are involved the effects may be enhanced or reduced.
Loucon is correct, .019 mg per L. Sometimes people get microgram confused with milligram. Microgram is µg. Press down ALT and type 230.
Pre the autopsy notation:
“A peak blood concentration of methamphetamine of 20 ng/mL was reported at 2.5 hr after an oral dosage of 12.5 mg. Blood levels of 200 - 600 ng/mL have been reported in methamphetamine abusers who exhibited violent and irrational behavior. High doses of methamphetamine can also elicit restlessness, confusion, hallucinations, circulatory collapse and convulsions.”
At 19 ng/ml he’s well below extreme abuser level.
People build up tolerance to opiates over time.
An opiate overdose death is quite, the person goes to sleep, the brain forgets to breathe. Not the way Floyd died.
Fentanyl has a rare complication not seen with other opiates, can occur at normal doses. Muscles go rigid, including the respiratory muscles. A can’t breathe situation.
Floyd was moving stiffly. Maybe the cops couldn’t get him in the car because he couldn’t bend into a sitting position.
Could be a major contributor to his death. Doesn’t excuse their not rendering aid when he went unresponsive.
Quiet,not quite.
Does this matter or make the cop less guilty? No. The guy was in handcuffs, subdued, and murdered over about 9 minutes ON CAMERA.
You methed up.
Thanks.
The “reporting limit” for Meth is 5.0 ng/ml, so, I assumed 19 ng was probably a non-event for health and behavioral issues.
Floyd's fentanyl level - 11 ng - is a whole new story.
The average fentanyl level for terminal cancer patients at death is 12 ng, and most of them are unconscious for days before they die.
The first reports I read about the George Floyd death said that one policeman heard Floyd snoring, and a second policeman said he thought Floyd fell asleep.
That sounded completely bizarre when I first read it, but in light of the fentanyl screen, it sounds completely possible.
By the way - the knee on the neck was completely legal the day Floyd died. That method of restraint is carefully described in the Minneapolis Police manual.
Today, the MPD revoked all forms of “neck restraint.”
I sprinted over to the Police Manual and copied the entire section before it disappears forever.
The more I read about this case, the more I think the four officers will get hung juries on all charges, or get released on appeal.
Have you read the Autopsy Report?
Floyd's neck, throat, and upper back had ZERO trauma - externally and internally.
I don’t think he suggested anything like that.
Some of us just like to be fully educated before we form an opinion on something.
I was not certain about my math.
I am absolutely certain about his Fentanyl screen.
Please see my Comment #14.
“Floyd’s neck, throat, and upper back had ZERO trauma - externally and internally. “
That’s hugely interesting. Makes me wonder just how much pressure the cop was (or wasn’t) applying with his knee.
Also, thanks for the math. I think, previously, I was under the impression he was “very” high at the time of the incident. The math shows he wasn’t.
Get ready for disappointment, Reno.
All four officers are going to walk on Reasonable Doubt.
(1) The knee restraint was completely legal and is clearly explained in the Police Manual.
(2) The autopsy found no trauma to Floyd's neck, throat, or upper back.
(3) Floyd's fentanyl screen was 11 ng. That's enough to put an average man to sleep.
(4) One officer stated that Floyd was snoring. A second officer stated he thought Floyd was asleep.
(5) Floyd died from cardiopulmonary arrest.
(6) Fentanyl causes death by pulmonary arrest.
Your math is correct. I found a source that says lethality can begin at 0.5 mg/L still way more than floyd had in his system. However that is for isolated meth OD. I have no idea what a lethal level might. e combined with other drugs and his chronic health problems. Nothing occurs in isolation
