Miami police arrested 76 people during the Ultra electronic music festival over the weekend, amid tight security after a death at last year`s rave.
Most of the arrests were for drug possession or the sale of illegal products, a police spokesman told AFP, who said there were no major incidents at the three day festival in downtown Miami.
Last year, a 21-year-old man died of an overdose and a security guard was seriously injured when crowds pushed down a security fence trying to get in.
Ultra, which has been held since 1999 and had featured many of electronic music`s best known stars, draws about 100,000 people a day.
Some local authorities have asked that the festival be cancelled because of the incidents it generates and the congestion it causes in Miami.
This year`s event was headlined by David Guetta of France, the United States` Skrillex, Carl Cox from Britain and Dutch performers Tiesto and Armin Van Buuren.
