A 24-year-old man died at home and 18 others were transported to emergency rooms after taking Ecstasy at an all-night New Year's Eve rave held at the Los Angeles Sports Arena, according to a report released Thursday.

The report, by the U.S. Centers for Disease Control and Prevention, comes in the same week that officials in the San Francisco area said a second man had died after taking Ecstasy at a Cow Palace rave held over Memorial Day weekend.

At the Cow Palace rave -- which, like the New Year's Eve rave in L.A., was held at a publicly owned venue -- authorities arrested more than 70 people and seized over 800 Ecstasy tablets. At least nine other partygoers went to hospitals with Ecstasy overdoses.

A 23-year-old man died the day after the rave, and a second man, 25, died on Sunday.

The report of the New Year's Eve overdoses, published Thursday in the CDC's Morbidity and Mortality Weekly Report, detailed a massive party where authorities appeared to anticipate drug use.

The rave attracted 45,000 attendees, according to the CDC. Los Angeles police were on site with undercover narcotics officers, and 14 ambulances were stationed at the facility. Emergency rooms were alerted to expect patients from the rave.

The 18 people who were sent to the hospital were between the ages of 16 and 34. In addition to using Ecstasy, 10 had drunk alcohol, and five had also used other drugs.

The 24-year-old man died at home of multiple drug intoxication, the CDC said. The man had no chronic illnesses. The man’s friends informed authorities that he had “used Ecstasy and cocaine at the rave and injected heroin at home afterward.”

One emergency-room patient suffered organ failure, requiring a stay in the intensive-care unit after suffering a seizure and liver and kidney failure. He needed dialysis to detoxify his blood, according to the report, and remained hospitalized for 28 days. The report said that, after his discharge, the man continued to need dialysis.
