MDMA and ecstasy

The party drug par excellence, whose tablet strength has tripled in fifteen years. Serious accidents rarely come from the substance alone: they come from heat, from drinking too much water, and from repeated doses.

Where the substance comes from

MDMA is entirely synthetic, made from chemical precursors in clandestine laboratories concentrated in north-west Europe. Crystal is now the commonest form, ahead of tablets. Tablets are pressed with logos and colours that act as a brand and guarantee nothing: two tablets bearing the same logo can hold anything from 20 to over 250 milligrams, and some contain no MDMA at all but a synthetic cathinone or PMMA, which is far more toxic.

A little history

MDMA was synthesised in 1912 by Anton Köllisch at Merck in Darmstadt, as a mere intermediate in the manufacture of a drug against bleeding; patented in 1914, it was never marketed and slept in the archives. The American army tested it on animals in the 1950s. It was the chemist Alexander Shulgin who resynthesised it in 1976, described its effects on himself and introduced it to Californian psychotherapists, who used it discreetly for a decade.

In a 1970s office, a psychotherapist listens to a woman client seated in a low armchair
Before reaching the street, MDMA first circulated quietly among psychotherapists.

Its move to the street took place in Texas in the early 1980s under the name "ecstasy"; the United States banned it as an emergency measure in 1985, despite the therapists' protests. In Europe it became the drug of rave culture and electronic music — Ibiza in 1987, Britain's "second summer of love" in 1988 — then of free parties and clubs; the death of Leah Betts in 1995 fixed the image of its danger in Britain.

Since the 2010s MDMA has been coming back through the door of research: the phase 3 trials run by the MAPS organisation on post-traumatic stress disorder gave promising results, Australia authorised its prescription by psychiatrists in 2023, but the American drug agency refused approval in 2024, judging the data insufficient. On the street, pills have become far stronger than twenty years ago.

The forms it takes

In a festival harm-reduction tent, a volunteer tests tablets and crystals with a reagent kit
Logo-pressed tablets, crystals, hand-filled capsules: two tablets with the same logo can contain anywhere from 20 to over 250 mg.

What the user is looking for

In an electronic music venue, four friends embrace with closed eyes under violet lights
Empathy, the urge to talk and touch, sensitivity to music: the attachment felt is a pharmacological effect.

A very characteristic emotional opening: empathy, a wish to talk and touch, social awkwardness gone, heightened response to music and light. The effect builds over thirty to sixty minutes and lasts three to five hours. It is that affective dimension rather than the stimulation that gives MDMA its particular place — and makes it deceptive, because the attachment felt is a pharmacological effect.

Immediate unwanted effects

In a festival first-aid tent, volunteers cool down an overheated young woman
Heatstroke after hours of dancing in a hot venue is the mechanism behind most deaths.

Medium and long-term risks

On a rainy morning, a sad-looking young woman gazes at the street through a tram window
The comedown, with sadness and irritability, can last several days.

The come-down is the most constant feature: two to four days of low mood, irritability and anxiety while serotonin stores rebuild. Using more often prevents that rebuilding; beyond monthly use, users unanimously describe that “the magic does not come back”, with persistent depression and sleep and memory problems. The available work points to damage to serotonergic terminals with heavy repeated exposure. Regular use adds dental wear from bruxism and a risk to the heart valves.

Combinations are dangerous: with serotonergic antidepressants, serotonin syndrome; with monoamine oxidase inhibitors, a risk to life; with cocaine or amphetamines, cumulative cardiac load.

How to spot use

A young man comes home at dawn up the stairs of his building, lollipop in his mouth and chewing gum in hand
Lots of chewing gum, lollipops, clenched jaw, coming home at dawn then several days of very low mood: the signs that recur after the same weekends.

Chewing gum in quantity, lollipops, a clenched jaw and night-time grinding, huge pupils, coming home at dawn, then two or three days of very low mood and withdrawal recurring after the same weekends. Urine detection: two to four days.

Why the effect is stronger in adolescents

An addiction doctor points to the frontal lobe on a brain model for a young man and his mother
In adolescents, the reward circuit matures well before the prefrontal cortex that should rein it in.

At the same dose in a lighter body, the concentration reached is higher in an adolescent than in an adult. More importantly, the reward circuit matures well before the prefrontal cortex that is supposed to restrain it: the pull to repeat is stronger and the brake weaker, which markedly shortens the gap between first use and problem use. Use established before eighteen multiplies the risk of adult dependence whatever the substance — including legal ones such as the caffeine in energy drinks, alcohol or nicotine.

When to call an ambulance without hesitating

Loss of consciousness, seizures, severe confusion, slow or irregular breathing, blue lips, chest pain, very high temperature, uncontrollable agitation, suicidal thoughts. In those situations call the emergency services and say what was taken: treatment depends on it.
