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, dopamine, and norepinephrine. Like other amphetamines, MDMA causes these neurotransmitters to be released from their storage sites in neurons, resulting in increased neurotransmitter activity.
