- People with pain or blood vessel problems in their lower limbs that could interfere with study procedures
- People with a currently unstable liver or bile duct condition, as assessed by the study doctor

- People with uncontrolled high blood pressure, defined as repeated readings of 140 mmHg or higher (top number) or 90 mmHg or higher (bottom number)
- People with a history of a serious type of irregular heartbeat called ventricular arrhythmia, except for occasional minor irregularities not linked to heart disease

- People with a history of certain heart rhythm problems (other than minor irregularities not linked to heart disease) within the 12 months before screening
- People with additional risk factors for a serious heart rhythm problem called Torsade de pointes — for example, heart failure, low potassium levels, or a family history of Long QT Syndrome

- People with an active substance use disorder involving illicit drugs (other than cannabis) or misused prescription drugs in the 12 months before enrolling

- People who need to take medications during experimental sessions that could affect heart rhythm (specifically, those that may prolong the QT interval)
- People who have used unregulated Ecstasy (street MDMA) more than 10 times in the past 10 years, or at least once within 6 months of the first experimental session

- People with a current eating disorder that involves compensatory behaviours
- People with current major depressive disorder that also involves psychotic features
- People with a history of, or current, primary psychotic disorder or bipolar disorder type 1

- People who lack social support or do not have a stable living situation
- People who have previously taken part in an MDMA clinical trial sponsored by MAPS
- Current employees (or their immediate family members) of MAPS, MAPS Public Benefit Corporation, or MAPS Europe B.V., or people in a personal relationship with the site investigator
- People with a chronic pain condition separate from fibromyalgia that they rate as more painful than their fibromyalgia
- People with severe anxiety or significant anxiety symptoms that would interfere with MRI brain scanning, such as panic disorder
- People who are currently a patient of the specific paired clinician enrolled in the study
