MDMA, which can be taken as a powder or pill, is also sold under the names Molly and ecstasy (among others). It’s a synthetic psychoactive drug, which triggers parts of the brain linked with happiness and euphoria, and boosts energy levels. It also boosts empathy. In the United States, the drug was used legally in a therapeutic context for decades, including within couples therapy, until it crossed over into club culture and, in 1985, during the Reagan-era “War on Drugs” was made an illegal Schedule 1 drug. Here in the UK, it’s classified as a Class A drug alongside the likes of cocaine and heroin, but is still widely taken for recreational purposes.
