MDMA (3,4-methylenedioxy-N-methylamphetamine), most commonly known today by the street name ecstasy (often abbreviated to E, X, or XTC), is a semisynthetic member of the phenethylamine class of psychoactive drugs. MDMA is unique in that it is one of the few popular recreational drugs that falls under many broad categories of substances, including amphetamines/stimulants, psychedelics, and the empathogenic-enactogens. The drug is well known for its ability to produce feelings of overwhelming euphoria, intimacy, and connectedness with others, and is commonly associated with the rave culture and its related genres of music. MDMA is illegal in most countries, and its possession, manufacture or sale may result in criminal prosecution.
