MDMA is the chemical shorthand for the drug 3,4-methylenedioxymethamphetamine. Other names that MDMA goes by include: Molly, Ecstasy, E, X, and Adam.
MDMA is famous for being a drug used at raves and in club settings. It is both a stimulant and a psychedelic (or hallucinogen), so it both gives people energy and changes how what their senses perceive.
Someone on MDMA may see colors and hear music differently, often making the experience more pleasurable. Changes to sensory perception are by raves focus so much on vivid colors and music as part of the experience.
MDMA also increases feelings of empathy and closeness towards others.
MDMA is a Schedule I medication according to the Drug Enforcement Agency (DEA), meaning it has a high potential for abuse and addiction and no recognized medical usage.
People who become addicted to MDMA will experience withdrawal symptoms if they stop using the drug. An inability to stop a drug is called dependence and may require MDMA detox.
