- noun methyldiamphetamine, a synthetic drug which is chemically related to the stimulant amphetamines, but which in some users elicits hallucinogenic experiences supposedly similar to those associated with LSD. The drug was first popular in the early 1970s in the USA, and came once again into vogue in the late 1980s in the UK, where it was known as adam or, more usually, ecstasy, and became the drug of choice among young club-goers and dancers.
