The neurotoxic effects of the drug appear to decrease several areas of brain activity, and long-term use appears to decrease the volume of the brain.

Gaylord Ellison, a researcher with almost 40 years experience studying the neurotoxic effects of amphetamines said that ecstasy degenerates the axons in several areas of the brain.

Dr. Joseph Frascella of NIDA's Division of Treatment Research and Development said that,"The message from these studies is that MDMA does change the brain and it looks like there are functional consequences to these changes".
