MDMA is a synthetic drug that alters mood and perception, often producing feelings of euphoria, empathy, and emotional well-being. Short for 3,4-methylenedioxy-methamphetamine, MDMA is chemically similar to both stimulants and psychedelics. Under its influence, colors and sounds (especially music) are experienced more intensely, which has made it a popular recreational drug, particularly at raves and music festivals. Though it has a reputation as a club drug, MDMA’s ability to help people gain access to their emotions made it a popular drug to treat depression in the late 1970s, as well as in couples therapy to foster closeness. The psychologist and psychotherapist who first brought MDMA to the world of psychotherapy, Leo Zeff, reportedly called the drug “penicillin for the soul.” But after it became a popular recreational drug, the DEA added MDMA to the list of Schedule 1 drugs in 1985.
In the early 2000s, however, the Multidisciplinary Association for Psychedelic Studies (MAPS) launched the first clinical study into MDMA’s therapeutic potential, specifically for PTSD. In one study, 68% of the 107 participants involved no longer had PTSD one year after treatment. Now, pure crystal MDMA (the only form of the drug that may be legally administered by a medical professional) is in Phase III clinical trials for use as a therapeutic aid in the treatment of PTSD and has been granted “Breakthrough Therapy” status by the FDA. MDMA is on track for full FDA approval and could be prescribed by doctors as early as 2022.
MDMA also has the potential to alleviate social anxiety and save struggling relationships.
MDMA can be deadly at high doses and when combined with other drugs, especially PMA/PMMA.
Sometimes hope comes in micro-doses. This guide will walk you through the process and how to best use the healing potential of psychedelics in a safe, intentional way to heal depression.
For most clinical trials, researchers administer doses between 80 and 150mg of MDMA. At this dose level, the onset of effects occurs approximately 20 to 60 minutes after taking the drug, and the characteristic effects (euphoria, increased empathy, and energy, enhanced sensations) typically last for three to five hours.
The high is usually characterized by a relaxed, euphoric state, including emotional openness, reduction of negative thoughts, and a decrease in inhibitions. MDMA can make users feel like all is well in the world, and connecting with others becomes easy. Bodily sensations and touch become enhanced, and sounds and colors can appear more intense.
These effects themselves could be important to the drug’s healing potential by offering users greater access to their inner selves. But researchers also believe that the openness MDMA fosters could speed up the bond between patient and therapist, creating a setting conducive to healing.
Your experience will also be affected by the quality of the MDMA you ingest. MDMA purity is notoriously variable, especially in tablet form. In the US, for instance, the average MDMA concentration in ecstasy tablets is reported to be 30.13%.[1] But this includes samples as low as 0% and as high as 100%. Also, while the sample size varies (from 1 to 1,000 pills), individual state averages can be double or half the national average.
Still, this is an improvement: In 2008, police seizures of the chemical precursor safrole meant that, for years, street MDMA concentration in pills was often zero.[2] Since then, the percentage of dud pills (tablets containing no MDMA) has been falling. Meanwhile, the percentage of ecstasy pills containing MDMA alone, without any adulterants, has been climbing. In 2009, 60.1% of ecstasy tablets worldwide contained no MDMA, whereas just 8.7% contained MDMA alone. By 2018, the situation was reversed: 8.8% of ecstasy tablets contained no MDMA, while 54.8% contained MDMA alone.[3]
Part of this has to do with new manufacturing methods. Underground chemists now synthesize the drug with a less heavily restricted precursor. But it also has to do with the darknet, where vendor ratings and competition drive the quality up.[4]
Far from the time when there was too little MDMA in pills, nowadays there’s often too much. Super-strength ecstasy tablets have made headlines in recent years for killing unsuspecting users. Where the MDMA content in ecstasy pills is traditionally between 80 and 120mg, some have been found to contain upwards of 300mg.[5] A high-end dose like this can be dangerous enough in itself, let alone when you’re not expecting it.
Reagent test kits from Bunk Police in addition to the services provided by EcstasyData.org and Pill Reports are excellent resources for gauging pill safety. Short of testing the drug before consuming it, the safest way to use ecstasy pills is to start with half a tablet and gauge how you feel after an hour.[6][7]

NOTE: Effects listed here aren’t meant to be comprehensive, particularly at the lower dose ranges. They may be subject to change as more reliable, more widely representative data become available. These dose ranges are intentionally conservative to account for the high variability of MDMA purity. They assume 100% (aka 84%) purity.

Microdosing MDMA is not as common as LSD and psilocybin, but with the general rise in interest in microdosing, some have wondered if the practice could enhance their moods and boost their energy. While some people have reported success with an MDMA regimen, we do not recommend it. There is a lot of evidence to suggest that frequent MDMA use can be very bad for you. After all, MDMA is not like classic psychedelics; it’s an amphetamine and a stimulant that does very different things to your body than a tab of LSD. Common effects may include:

While MDMA is known for giving rise to feelings of euphoria and general well-being, the benefits of the drug extend beyond several hours of bliss—it holds the potential to heal trauma, anxiety, disconnection, and possibly more. A recent study that looked at MDMA’s effects on the brain found that this healing could come from the drug’s ability to decrease activity in the brain’s limbic system and reduce communication between the temporal lobe and prefrontal cortex, both of which are involved in emotional control and response. People with anxiety see an increase in activity in these areas, suggesting that MDMA can help alleviate related mood disorders.
MDMA also increases communication between the amygdala and the hippocampus, according to the study. People suffering from PTSD, on the other hand, see a reduction in communication between these areas.
Another recent study by Dr. Ben Sessa found that MDMA could also be the best intervention to treat acute childhood trauma by offering people safe access to their emotions. “In combination with psychotherapy, [MDMA] provides the capacity to hold the traumatized patient in a state of emotional security, providing a state of empathic self-reflection,” Sessa writes, adding that, “for the first time in their lives, they can be with their traumatic memories without being overwhelmed by the powerful negative effect that usually accompanies recall of their most frightening thoughts.” This empathic self-reflection is also one of the reasons MDMA is proving to be such an effective treatment for PTSD.
MDMA is also known for fostering a greater sense of connection and empathy in users, making it a strong antidote to feelings of distance and disconnectedness, particularly between couples. Relationship therapists are starting to use the drug in their sessions to help couples enhance communication, heighten intimacy, and reconnect. It’s not called “the love drug” for nothing.
