Are you one of those people that think he somehow gained immunity to fentanyl?
@EverySingleTIme @dave
You need a triple take it seems. He talked about a low level of norfentanyl, a metabolite of fentanyl. That's something that is created in your body, as it tries to process fentanyl. But if fentanyl OD kills you quickly, there won't be much time for norfentanyl to develop. Hence a death from fentanyl overdose would leave a low amount of norfentanyl in your body.
Of course, the argument easily falls like this: he took fentanyl much earlier in the day, the norfentanyl had time to accumulate in his body, the police catch him, he ingests whatever drugs he still had on him so the cops don't find it, this sends his body into OD.
