I would say unlikely because when the body processes Fentanyl it turns into Norfentanyl, which Floyd had 5.6 ng/ml of in his tox screen. That means he had already processed 5.6 ng/ml and he had 16.6 ng/ml in his system to begin with. The average lethal dose is low, but another TD user posted a study on overdose thresholds and that study said some people overdose well in excess of 20 ng/ml depending on tolerance. Keep in mind Floyd was 6'4" and probably had a high tolerance.
Did he quickly use up his stash in his car, as the police approached, so they would not find drugs?
My assumption is that he stuck a balloon up his ass and it popped.
