MDMA does not leave the body as soon as its noticeable effects wear off. The main psychoactive effects commonly last for several hours, but the body continues to metabolize and eliminate MDMA after the person no longer feels intoxicated. Controlled human studies have measured an MDMA elimination half-life of roughly 7 to 9 hours, although […]

MDMA and antidepressants do not have one universal interaction. The answer depends on the antidepressant class, the individual medicine, how long it has been taken, and whether other substances are involved. Some antidepressants can reduce the subjective effects of MDMA. Others create more serious interaction concerns. Monoamine oxidase inhibitors, or MAOIs, deserve particular caution because […]

MDMA strongly affects serotonin activity in the brain. That is part of the reason it can alter mood, emotional closeness, sensory perception and body temperature. It also means MDMA can contribute to serotonin syndrome, a potentially serious toxic reaction caused by excessive serotonergic activity. The risk becomes especially important when MDMA is combined with certain […]

An MDMA overdose does not always look like the type of overdose people associate with opioids. A person may still be awake while developing dangerously high body temperature, severe agitation, a rapid heartbeat, confusion or seizures. The condition can deteriorate quickly. MDMA, also known as ecstasy or Molly, has stimulant effects and can interfere with […]

MDMA can produce euphoria, increased energy, emotional openness and intensified sensory experiences. Those effects are only one part of its pharmacology. MDMA also affects the cardiovascular and nervous systems. The same substance that changes mood and perception can increase heart rate, blood pressure and body temperature. The DEA describes unwanted effects including muscle tension, tremor, […]

“MDMA testing” can mean two very different things. One is testing a drug sample to determine what it contains. The other is testing a person’s biological sample, such as urine or blood, for evidence of exposure. Those questions require different methods and should not be mixed together. Drug checking vs biological testing A drug-checking service […]

“Fake MDMA” can describe more than one problem. Sometimes another substance is sold in place of MDMA. In other cases MDMA is present, but the product also contains another psychoactive drug. A third possibility is often overlooked: the product contains genuine MDMA, but substantially more than expected. Those are different problems and should not be […]

MDMA is not legal for ordinary recreational possession, purchase or sale in the United States. Under federal law, 3,4-methylenedioxymethamphetamine (MDMA) remains a Schedule I controlled substance. The DEA specifically identifies MDMA, also known as ecstasy, as a Schedule I drug. See the current classification on the DEA drug scheduling page. What does Schedule I mean? […]

MDMA, Molly and ecstasy are frequently discussed as if they were three different drugs. Chemically, that is not quite right. MDMA is a specific chemical: 3,4-methylenedioxymethamphetamine. Ecstasy is a street term commonly associated with pressed tablets sold as containing MDMA. Molly usually refers to powder, crystals or capsules sold as MDMA, particularly in the United […]
