Why can you get memory complaints with ecstasy use?

MDMA appears to be harmful to the brain cells that use serotonin as a messenger (neurotransmitter). One of the most important parts of the brain for memory, the hippocampus, has many serotonergic brain cells. The hippocampus ensures that memories from your short-term memory are stored in the long-term memory so that you will remember it in 5 years and hopefully at 90.
