MDMA, or 3,4-methylenedioxymethamphetamine, is a synthetic drug known for its stimulant and empathogenic effects. It is commonly associated with recreational use at music festivals and parties, where it enhances sensory perception and emotional connection. Users often report feelings of euphoria, increased energy, and a sense of closeness to others. Originally developed in the early 20th century, MDMA was studied for potential therapeutic uses, particularly in psychotherapy. However, it became popular as a recreational drug in the 1980s and was classified as a Schedule I controlled substance in the United States. Research is ongoing to explore its potential benefits in treating conditions like PTSD and anxiety.
