GAINESVILLE, Fla. - More than two dozen monkeys that were test subjects in nicotine addiction research have been moved from an Arkansas lab to a Florida primate sanctuary.

The Gainesville Sun reported Wednesday that the squirrel monkeys are now at the city's Jungle Friends Primate Sanctuary. The U.S. Food and Drug Administration suspended the nicotine addiction study last year after learning that four research monkeys had died.

FDA commissioner Scott Gottlieb said in January that the study didn't meet agency standards and would be stopped. The monkeys were sent, with US$1 million for their care, to Jungle Friends.

The monkeys arrived in November and are now slowly being introduced to different foods, materials and experiences. They're set to move in the spring to large outdoor enclosures that mimic their natural habitat.
