Stephan Bonnar, a former UFC fighter who died in December, passed away due to an unintentional drug overdose. In response to a query from MMAFighting.com, the Clark County (Nev.) coroner’s office stated that Bonnar’s death was caused by a mix of fentanyl, parafluorofentanyl, and mitragynine intoxication.
Bonnar’s behavior had been unpredictable lately, leading to speculation about a possible addiction to opioids. Fentanyl, a synthetic opioid, has been deemed by the United States Drug Enforcement Administration as the most lethal drug threat the country has ever faced. According to their reports, it is responsible for more deaths among people under 50 than any other cause, including heart disease, cancer, or homicide.The UFC announced on Christmas Eve that Bonnar had passed away, and initially reported that his death was likely due to heart issues. In February, the organization held a “celebration of life” event in his honor. Bonnar’s 2005 fight against Forrest Griffin, which took place during the first season finale of the Ultimate Fighter TV show, is widely regarded as a pivotal moment in the UFC’s rise to prominence.
