10 Alcohol and Drug Research, Volume 7: Neurotoxicity of MDA and MDMA

This paper argues that the dangers associated with MDA should be assumed to apply with MDMA unless it is proved otherwise. Evidence is given of the two drugs having a similar degree of lethality when they are tested on mice, rats, guinea pigs, dogs and monkeys. The tests used involved the classic test for poisons: trying larger and larger doses on groups of animals until 50% of the animals died within 24 hours. The paper also mentions that both MDA and MDMA killed more mice when they were crowded together, "a phenomenon long associated with amphetamine".
