When the TomorrowWorld festival opens outside Atlanta on Friday, concertgoers can expect to see safety measures that have become common at European electronic dance music festivals but have yet to catch on in the United States: a nonprofit drug education group will be giving advice, not only on the dangers of drug abuse, but also on how those who choose to take party drugs can use them more safely.

The music industry will be watching TomorrowWorld closely to see if organizers can avoid the kind of drug-related deaths that have marred several big dance-music festivals since March, most recently Electric Zoo in New York City. At least seven young people at these events have died of symptoms consistent with Ecstasy overdoses, and scores of others have been hospitalized, prompting promoters to cancel concerts and fueling worries among music executives that negative publicity could scare off investors and corporate sponsors, damaging a $4.5 billion industry.

Giving concertgoers tips on avoiding overdoses has been controversial in the United States, where zero tolerance for drugs has been standard policy among promoters. Such programs — from fliers describing guidelines for dosages of Ecstasy (MDMA, also known as Molly) to public service announcements from D.J.’s about taking breaks from dancing and not mixing the drug with alcohol — have also encountered resistance from some police and local officials, who say they can be seen as condoning the use of illegal drugs, drug policy experts said.

But Shawn Kent, the United States project manager for ID&T, the Belgian company producing TomorrowWorld, said promoters are facing a hard reality: even with zero tolerance, tight security, confiscation of drugs at entrances, undercover narcotics officers in the crowd and paramedics and ambulances on hand, promoters cannot stop all concertgoers from making bad decisions. “This is a societal issue,” he said. “The way to help people who have these issues is to give them information. At some point, it’s individual responsibility.”
