Derek Chauvin stabbed by inmate in federal prison, seriously injured

So first of all, you seem to be confusing MG and NG/ML. The MG measurement is generally used to measure a dosage level, so for example, if a doctor prescribes you a medication, the amount you take is usually measured in MGs. NG/ML on the other hand is more often used to measure drug concentration in one’s blood stream. For George Floyd, we don’t have an exact dosage that he took, all we have are his blood concentration levels, however since his blood tests were taken after his death, his drug concentration levels would likely be considerably higher than the actual levels when he was still alive. His blood concentration levels were about the same as the average DUI driver who survived, but again his blood tests were made after his death, so his actual blood level was likely considerably lower

In regards to what would be a lethal dose, it varies based on the person’s body and the circumstances, but 3 MG would be considered a dangerous amount on its own for a significant portion portion of the population, but again, for George Floyd we do not have a dosage measurement, we only have his drug concentration levels. 3MG/ML would definitely not be considered a dangerous level under the vast majority of circumstances

Again, it all varies, so the big question is does the medical evidence suggest that the drug concentration in Floyd’s blood was lethal amount for him. The evidence overwhelmingly suggests no, the Medical Examiner stated he would only consider his blood levels to be fatal if there was no other medical evidence available, including what was reported from the EMTs and the emergency room doctors, along with the video evidence.

The medical evidence goes against the notion that drugs were the primary cause of death, and we have testimony from literally every medical expert who examined Floyd to support the conclusion that it was not drugs that killed him.
