@Rocketman123: He didn't have "traces" of fentanyl
Per the autopsy report he had a level of 11ng per ml in his blood that means 0.0011% of his blood was composed of pure Fentanyl. To give you an idea how much that is, 1% makes up ALL your white blood cells AND platelets (what JW's are allowed to take in a transfusion), so 1 platelet in 1000 platelets was not a platelet but Fentanyl - in other words, he had more Fentanyl than he had trace amounts of copper or most other metals except for iron that are naturally present in our body.
“If he were found dead at home alone and no other apparent causes, this could be acceptable to call an O.D. [Over Dose],” the notes say. “Deaths have been certified with levels of 3,” the notes indicate.
And not only did he have Fentanyl, he ALSO had 19ng of Methamphetamines and other drugs in his body, which alone would've gotten him a DUI/DWI, but has proven fatal in combination with alcohol or other drugs in some cases. Methamphetamines are less potent so it requires more of it to kill you, but then they found a number of half chewed and full meth/fentanyl pills on the floor of the police cruiser in which he was sitting, with his blood and DNA on it, so presumably he just ingested those and either vomited with blood or spit them out (although it's unlikely the police wouldn't have noticed his mouth was full).
Let's say we 'recycled' the blood in his body, extracted the Fentanyl again, you could have overdosed 3-4 "normal" healthy people with the result.
