In general, MDMA users report feeling the onset of subjective effects within 30–60 minutes of MDMA consumption and reaching the peak effect at 75–120 minutes, which then plateaus for about 3.5 hours.JOURNAL, Liechti ME, Gamma A, Vollenweider FX, Gender differences in the subjective effects of MDMA, Psychopharmacology, 154, 2, 161–8, March 2001, 11314678, 10.1007/s002130000648, The desired short-term psychoactive effects of MDMA have been reported to include:
  • Euphoria – a sense of general well-being and happiness
  • Increased self-confidence, sociability and feelings of communication being easy or simple
  • Entactogenic effects – increased empathy or feelings of closeness with others and oneself
  • Relaxation and reduced anxiety
  • Increased emotionality
  • A sense of inner peace
  • Mild hallucination
  • Enhanced sensation, perception, or sexuality
  • Altered sense of time
The experience elicited by MDMA depends on the dose, setting, and user. The variability of the induced altered state by MDMA is lower compared to other psychedelics. For example, MDMA used at parties is associated with high motor activity, reduced sense of self-identity as well as poor awareness of the background surroundings. Use of MDMA individually or in a small groups in a quiet environment and when concentrating, is associated with increased lucidity, capability of concentration, sensitivity of aesthetic aspects of the background and emotions, as well as greater capability of communication with others.JOURNAL, Landriscina F, MDMA and the states of Consciousness, Eleusis, 1995, 2, 3–9, In psychotherapeutic settings MDMA effects have been described by infantile ideas, alternating phases of mood, sometimes memories and moods connected with childhood experiences.JOURNAL, Baggott MJ, Kirkpatrick MG, Bedi G, de Wit H, Intimate insight: MDMA changes how people talk about significant others, Journal of Psychopharmacology, 29, 6, 669–77, June 2015, 25922420, 4698152, 10.1177/0269881115581962, Sometimes MDMA is labelled as an "empathogenic" drug, because of its empathy-producing effects.JOURNAL, Schmid Y, Hysek CM, Simmler LD, Crockett MJ, Quednow BB, Liechti ME, Differential effects of MDMA and methylphenidate on social cognition, Journal of Psychopharmacology, 28, 9, 847–56, September 2014, 25052243, 10.1177/0269881114542454, JOURNAL, Wardle MC, de Wit H, MDMA alters emotional processing and facilitates positive social interaction, Psychopharmacology, 231, 21, 4219–29, October 2014, 24728603, 4194242, 10.1007/s00213-014-3570-x, Results of different studies show its effects of powerful empathy with others.

MDMA is often considered the drug of choice within the rave culture and is also used at clubs, festivals and house parties. In the rave environment, the sensory effects from the music and lighting are often highly synergistic with the drug. The psychedelic amphetamine quality of MDMA offers multiple reasons for its appeal to users in the rave setting. Some users enjoy the feeling of mass communion from the inhibition-reducing effects of the drug, while others use it as party fuel because of the drug's stimulatory effects.BOOK, Reynolds, Simon, vanc, Generation Ecstasy: Into the World of Techno and Rave Culture, 1999, Routledge, 978-0-415-92373-6, 81,weblink MDMA is used less frequently than other stimulants, typically less than once per week.MDMA is sometimes taken in conjunction with other psychoactive drugs such as LSD, psilocybin mushrooms, and ketamine, an act called "candy-flipping".BOOK, Capuzzi, David, Gross, Douglas R., vanc, Youth at Risk: A Prevention Resource for Counselors, Teachers, and Parents, John Wiley & Sons, 978-1-119-02694-5, 379,weblink 2014-11-21,

Small doses of MDMA are used as an entheogen to enhance prayer or meditation by some religious practitioners.MDMA and Religion. CSP. Retrieved on 11 June 2011. MDMA has been used as an adjunct to New Age spiritual practices.JOURNAL, Watson L, Beck J, New age seekers: MDMA use as an adjunct to spiritual pursuit, Journal of Psychoactive Drugs, 23, 3, 261–70, 1991, 1685513, 10.1080/02791072.1991.10471587,


MDMA has become widely known as ecstasy (shortened "E", "X", or "XTC"), usually referring to its tablet form, although this term may also include the presence of possible adulterants or dilutants. The UK term "mandy" and the US term "molly" colloquially refer to MDMA in a crystalline powder form that is thought to be free of adulterants. MDMA is also sold in the form of the hydrochloride salt, either as loose crystals or in gelcaps.In part due to the global supply shortage of sassafras oil, substances that are sold as molly frequently contain no MDMA and instead contain methylone, ethylone, MDPV, mephedrone, or any other of the group of compounds commonly known as bath salts.AV MEDIA, 13 August 2014, Molly Madness, TV documentary, National Geographic Channel, Drugs, Inc., B00LIC368M, AV MEDIA, 10 December 2014, Manic Molly, TV documentary, National Geographic Channel, Drugs, Inc., B00LIC368M, Powdered MDMA ranges from pure MDMA to crushed tablets with 30–40% purity. MDMA tablets typically have low purity due to bulking agents that are added to dilute the drug and increase profits (e.g., lactose) and binding agents. Tablets sold as ecstasy sometimes contain 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxyethylamphetamine (MDEA), other amphetamine derivatives, caffeine, opiates, or painkillers. Some tablets contain little or no MDMA. The proportion of seized ecstasy tablets with MDMA-like impurities has varied annually and by country. The average content of MDMA in a preparation is 70 to 120 mg with the purity having increased since the 1990s.MDMA is usually consumed by mouth. It is also sometimes snorted.{{multiple image| align = center| direction = horizontal| total_width = 600| image1 = Ecstasy monogram.jpg| width1 = 434| height1 = 424| alt1 = Image of Ecstasy tablets| caption1 = Ecstasy tablets which may contain MDMA| image2 = Tan MDMA Crystals.jpg| width2 = 4032| height2 = 3024| alt2 = Image of a chunk of impure MDMA| caption2 = A salt of MDMA (typically white) with impurities, resulting in a tan discoloration| image3 = Crushed MDMA crystals.jpg| width3 = 4032| height3 = 3024| alt3 = 1 gram crushed MDMA crystals| caption3 = Crushed MDMA (1 gram) crystals| image4 = | width4 = 1632| height4 = 1224| alt4 = Image of highly pure MDMA in capsules| caption4 = High purity MDMA in capsules}}

Adverse effects


Acute adverse effects are usually the result of high or multiple doses, although single dose toxicity can occur in susceptible individuals. The most serious short-term physical health risks of MDMA are hyperthermia and dehydration. Cases of life-threatening or fatal hyponatremia (excessively low sodium concentration in the blood) have developed in MDMA users attempting to prevent dehydration by consuming excessive amounts of water without replenishing electrolytes.JOURNAL, White CM, How MDMA's pharmacology and pharmacokinetics drive desired effects and harms, Journal of Clinical Pharmacology, 54, 3, 245–52, March 2014, 24431106, 10.1002/jcph.266, The immediate adverse effects of MDMA use can include:{{div col|colwidth=22em}}
