MDMA (ecstasy function by increasing central nervous system (CNS) serotonin levels. The overlap between stimulants and hallucinogens is common because many stimulants modulate CNS serotonin as well.

Most hallucinogens directly stimulate serotonin (5-HT) receptors while MDMA, block re-uptake of serotonin from the synaptic cleft, increasing the time and amount of this excitatory neurotransmitter in the synaptic cleft. There are a number of 5-HT receptor subtypes and the specific receptor subtype, and location in the brain accounts for the varying effects of these hallucinogens.
