The man and woman at the Peterson Company on Empire Boulevard immediately became ill from the additive, which they said they bought at a bodega in Paterson, Moonachie Police Lt. Jeff Napolitano said.
Responding officers began treating the unresponsive pair with oxygen, then administered Narcan out of an abundance of caution, the lieutenant said.
It had no effect, he said.
"It was only after several minutes of oxygen and after the arrival of EMS and paramedics that they became responsive and explained what had happened," Napolitano said.
Both were taken to Hackensack University Medical Center, along with the bagged chocolate, the lieutenant said.
