The pulsing beats and neon lights of Electric Daisy Carnival Las Vegas were overshadowed by tragedy this past May, as Clark County coroner officials have now confirmed that drug overdoses claimed the lives of two festival attendees during the three-day event. The deaths have reignited concerns about substance abuse at the massive electronic dance music festival that draws hundreds of thousands to Las Vegas Motor Speedway each year.
According to News3LV, Azmi Atassi, 33, of Flagstaff, Arizona, and Opkar Mahal, 39, of North Las Vegas, both died on Sunday during the festival weekend that took place May 16-18. News3LV reported that a cause of death for Mahal was revealed to be MDMA toxicity, with hypertensive cardiovascular disease and obesity listed as other significant causes.
Mahal suffered what police described as a "medical episode" while attending the festival, according to EDM.com. He was transported to University Medical Center, where he later died. Meanwhile, Atassi was found deceased in his room at the Hilton Grand Vacations Club on Las Vegas Boulevard South, with officials believing he was in Las Vegas to attend the festival.
A Troubling Pattern of Festival Deaths
The 2025 fatalities add to a concerning trend that has followed EDC throughout its history. Something About Orange notes that there have been 11 total fatalities at EDC, although the number is likely higher. Past reported deaths have largely involved drug overdoses, as detailed by News3LV, according to figures collected by the law firm DiMarco | Araujo | Montevideo.
The festival's troubled history with substance abuse traces back to its Los Angeles origins. One tragedy that sparked a change in venue was the death of 15-year-old Sasha Rodriguez at the 2010 EDC in Los Angeles, as reported by Something About Orange. Sasha was too young to attend the festival but snuck in, took MDMA, and overdosed. Sasha's death was a major factor in the decision to relocate EDC to a 21+ venue in Las Vegas for future events.
The Deadly Combination of MDMA and Desert Heat
The combination of MDMA use and Las Vegas' extreme heat creates a particularly dangerous scenario for festival-goers. Something About Orange explains that MDMA interferes with the body's ability to regulate temperature, especially when combined with physical exertion and hot environments. Las Vegas summers can reach into the triple digits.
A stark example of this deadly combination occurred in 2017 when Michael Adam Morse, 34, of California died from what Las Vegas Review-Journal reported as "acute MDMA and TFMPP toxicity," with heat exposure listed as a contributing factor. His wife told the Review-Journal that the coroner's office said he had a body temperature of 109 degrees at the time of his death.
Rising Medical Emergency Calls
The scale of medical incidents at EDC has grown dramatically. According to data from the Las Vegas Review-Journal, the Electric Daisy Carnival had 1,090 medical emergency calls during the three-night festival in 2017, compared with 617 the previous year — a 77 percent increase. Fifteen people were hospitalized.
However, there have been some positive developments in overdose prevention. News3LV reported that the Southern Nevada Health District (SNHD) saw zero drug overdose deaths among Clark County residents during EDC this year. This success has been attributed to increased distribution of naloxone, with SNHD distributing 35,000 doses of Narcan in 2023.
The Las Vegas Metropolitan Police Department announced that they would be reviewing both incidents, as reported by EDM.com. The festival, which draws over 500,000 attendees over three days according to EDM.com, continues to grapple with balancing the celebration of electronic music culture with the stark realities of substance abuse in high-energy, high-temperature environments.
