Ecstasy / Molly
MDMA, also known as ecstasy or molly, is a psychoactive substance known for producing feelings of emotional openness, empathy, and heightened sensory perception. It primarily affects serotonin, dopamine, and norepinephrine systems in the brain, which contributes to its mood-altering effects. While some people report positive experiences, MDMA can carry significant physical and psychological risks, especially with repeated use or high doses.

This page summarizes anecdotal reports and community observations, not medical evidence. Reports may be incomplete, biased or inaccurate and are not medical advice or recommendations. “Risk” here refers to how frequently severe or prolonged symptom worsening is reported, not to proven causation or population-wide probability. Individual responses vary widely, and absence of issues in some users does not rule out significant reactions in others.

Within PFS/PSSD/PAS communities, MDMA is discussed in relation to its potential interactions with serotonergic, dopaminergic, and norepinephrine signaling pathways. MDMA ("ecstasy," "molly") is a psychoactive drug that strongly alters brain chemistry primarily by acting as a monoamine releaser—it drives large increases in serotonin and also increases norepinephrine and dopamine through transporter-mediated mechanisms. There is also clinical literature associating repeated/heavy MDMA exposure with longer-lasting changes in serotonergic function in some users, though outcomes vary and dose/pattern of use matters. These mechanisms may interact with pathways involving serotonergic, dopaminergic, or norepinephrine signaling that are often discussed in relation to PFS / PSSD / PAS. (jama) (fda)

Reports of Flares and Sometimes Lasting Worsening (for PFS/PSSD/PAS):
Among individuals who already have PFS/PSSD/PAS, MDMA is approached with significant caution as it is cited in community reports as preceding symptom worsening, with accounts describing both acute exacerbations that recover with time and longer-lasting declines in baseline. Although the severity and duration of these reactions vary between individuals, reports within this subgroup show a largely consistent direction toward worsening and flares rather than improvement. Because MDMA produces an intense, rapid serotonergic and sympathetic surge, reactions can be unpredictable in sensitized individuals, and "comedown" or post-use destabilization (sleep disruption, anxiety, mood changes, sexual symptom changes) is commonly described. In light of this pattern, many within the community view MDMA as carrying a meaningful risk for those with established PFS/PSSD/PAS, even in the absence of controlled data.
For individuals without these conditions, many people still experience significant acute and subacute adverse effects from MDMA, and serious medical complications can occur.
Evidence basis: Regulatory and medical safety discussions; clinical literature on serotonergic effects of MDMA; anecdotal reports (online forums, self-reports); no controlled studies examining PFS/PSSD/PAS-specific outcomes.
