But doctors at Los Angeles emergency rooms have told us that pure ecstasy can kill, including causing vital oxygen deprivation to organs. It's a hot topic: Two people who attended Electric Daisy Carnival in Las Vegas earlier this month died after leaving the festival. At least one of them had taken ecstasy.
There have surely been more than 10 raver deaths in the last 5 years, and an EMT who worked raves at the L.A. Coliseum and Sports Arena in recent years told us he knew of at least two other deaths that have gone unreported in the media. But here are 10 of the most high-profile losses since 2007, most of which were blamed on ecstasy:
10. Olivier Hennessy, a 31-year-old from Florida, was hit by a truck outside Electric Daisy Carnival in Las Vegas early on June 11. Cops said it was an accident -- that he crossed the road right in front of the vehicle near Gate 6 of Las Vegas Motor Speedway, where the three-night festival was held. Hennessy died the next Saturday after spending nearly a week in the hospital. Though the exact cause of death remains to be seen, friends said he had been drinking all day before the accident.
