Research conducted in animals and in in vitro cell cultures indicates that aminoindanes are relatively benign at recreational doses; however, the effects on humans have not yet been reported. MDAI and 5-IAI are reported to be highly potent selective serotonin releasing agents. Animal studies have shown that these analogues did not present any long-term neurotoxicity at the levels administered, but slight neurotoxicity on rodents was shown after administration of very high doses of 5-IAI.
