How witness credibility plays into the NFL’s disciplinary process is unclear. In a letter to Elliott informing him that he had been suspended for six games, the league said that advisors to league commissioner Roger Goodell had found “substantial and persuasive evidence” that Elliott had been violent toward Thompson. (The NFL’s personal-conduct policy says that a player who has not been charged with a crime can still be disciplined if there is “credible evidence” that he violated the policy.) An NFL spokesperson, asked what the “substantial and persuasive” standard means and how it compares to a preponderance-of-evidence one, was unable to clarify the issue for Deadspin.
5-MeO-DMT was first synthesized in 1936, and in 1959 it was isolated as one of the psychoactive ingredients of Anadenanthera peregrina seeds used in preparing Yopo snuff. It was once believed to be a major component of the psychoactive effects of the snuff, although this has recently been shown to be unlikely, due to the limited or sometimes even non-existent quantity contained within the seeds, which instead achieve their psychoactivity from the O - demethylated metabolite of 5-MeO-DMT, bufotenin .   It is metabolized mainly by CYP2D6 .
