Pharmacodynamics: MDMA is a phenylethylamine that has stimulant as well as psychedelic effects. MDMA is related in structure and effects to methamphetamine, however, it has significantly less CNS stimulant properties than methamphetamine. MDMA has a high affinity for 5-HT 2 receptors.
MDMA affects the brain by increasing the activity of at least three neurotransmitters (the chemical messengers of brain cells): serotonin, 89,90 dopamine, and norepinephrine. 91 Like other amphetamines, MDMA enhances release of these neurotransmitters 89â92 and/or blocks their reuptake, 93,94 resulting in increased neurotransmitter levels within the synaptic cleft (the space between the neurons at a synapse).
