Serum samples from the hospitalized patients analyzed at UCSF demonstrated fentanyl levels of 0.5–9.5 ng/mL (Table 2) (therapeutic range for analgesia = 0.6–3.0 ng/mL) (4); postmortem levels in the first two patients who died were 11 ng/mL (patient E) and 13 ng/mL (patient I). Norfentanyl, a major metabolite of fentanyl, was detected in the serum of nine patients; norfentanyl was not detected in postmortem testing of patients E and I, presumably because death occurred before metabolism of fentanyl to norfentanyl. All hospitalized patients had detectable serum levels of cocaine, cocaine metabolites (benzoylecgonine and ecgonine methyl ester), cocaethylene (a compound formed in vivo when ethanol is ingested in the presence of cocaine), or levamisole by LC-HRMS confirmatory testing (Table 2), all suggesting recent cocaine use. The absence of other opioids, such as heroin, methadone, or oxycodone, in serum (only one patient [D] was hydrocodone positive) was consistent with reports by the patients that most were not habitual opioid users. https://www.cdc.gov/mmwr/volumes/66/wr/mm6604a4.htm

The above indicates the 11 ng/ml of Fentanyl in George Floyd was at a level that is considered toxic. The 5.6 ng/ml Norfentanyl is a metabolite of Fentanyl. It is a powerful, fast-acting synthetic narcotic analgesic with a fast action duration. This would only amplify and exasperate the effects of Fentanyl.

The Methamphetamine found in Floyd's blood of 19 ng/ml is considered to be in the normal range. Methamphetamine level of <20 ng/mL (nanogram/millilitre) in blood is considered to be normal.

It's abundantly clear the Fentanyl would have been a contributing factor to Floyd's death. This should have been a major piece of evidence providing 'reasonable doubt' that Derek Chauvin purposely caused the death of George Floyd. In fact, the immobilization tactic used by Chauvin is a standard tactic taught in police academies across the nation (and world) in cases of resisting arrest. He properly used the tactic. George Floyd did not peaceably submit to arrest and resisted arrest.

This trial was a 'show trial' to appease the mob and an innocent man is jailed. This travesty of justice is from a lack of leadership caused by the Minneapolis mayor and the governor, who not only refused to act in securing the peace, but was complicit in fanning the flames of the riots. They had all the resources to prevent the riots from occurring. The governor was even provided Intel from the federal government. Instead, the governor allowed his daughter this Intel to be passed onto Antifa and BLM. The judge in this show trial acted wittingly to sacrifice the reputation and life of a police officer to the mob.
