Experimental: Psilocybin, Dose A
Single oral dose during an 8-hour supervised session (Specific dose withheld during conduct).
|
The specific doses (in mg) are intentionally omitted from this registration during the conduct of the trial to preserve masking and reduce expectancy effects.
The doses will be disclosed when results are reported after primary completion, by which point participants have been debriefed.

Health-related Quality of Life
Zeitfenster: Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
|
Health-related quality of life as measured by the RAND-36 self-report measure.
The RAND-36 contains 8 primary health scales (Physical functioning, Role limitations due to physical health, Role limitations due to emotional problems, Social functioning, Emotional well-being [mental health], Energy/fatigue [vitality], Bodily pain, and General health perception) and 2 summary scales (Physical Health Summary and Mental Health Summary) with possible scores for each scale ranging from 0 to 100.
Higher scores represent better health states and outcomes.

|
Self-perceived Quality of Life
Zeitfenster: Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
|
Self-perceived quality of life as measured by the WHOQOL-BREF self-report measure.
This measure includes 4 scales (Physical, Psychological, Social, and Environment), each with a possible range from 0 to 100.
Higher scores indicate a better quality of life.

|
|
Craving
Zeitfenster: Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
|
Craving, as measured by the Stimulant Craving Questionnaire-Brief (STCQ-Brief), a 10-item self-report tool measuring present-moment craving for stimulants.
A score is calculated by averaging all 10 items, with a possible range of 0 to 6. Higher mean scores reflect more severe craving.
|
Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
|
|
Withdrawal
Zeitfenster: Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
|
Methamphetamine withdrawal as measured by the Amphetamine Cessation Symptom Assessment (ACSA), a 16-item clinical rating tool used to measure the severity of amphetamine withdrawal symptoms over the preceding 24 hours.
Scores range from 0 to 64, with higher scores reflecting more severe withdrawal symptoms.
|
Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)

Severity of Dependence
Zeitfenster: Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
|
Severity of methamphetamine dependence, as measured by the Stimulant Use Disorder Severity Scale (StUDSS).
The StUDSS is a new patient-reported outcome instrument measuring the severity of symptoms for stimulant use disorder.
Total symptom severity is based on a sum of all items, with a possible range of 0 to 44.
Higher scores reflect more severe dependence.
The StUDSS also yields a categorical severity rating based on total criteria count: Mild (2 or 3 criteria), Moderate (4 or 5 criteria), or Severe (6 or more criteria).

|
Mystical-type experience during the day of dosing as measured by the Mystical Experience Questionnaire (MEQ).
The MEQ yields 4 scales: Unity, Positive Mood, Transcendence of Time and Space, and Ineffability.
Possible scores for each scale range from 0 to 5 and greater scores reflect higher intensity and greater depth of the mystical experience.

Zeitfenster: Day of dosing (≈7 hours)
|
Emotional breakthrough on the day of dosing as measured by the Emotional Breakthrough Inventory (EBI).
The EBI is a 6-item scale scored using a 0 to 100 Visual Analogue Scale (VAS) for each item.
The total overall score is calculated as the sum of all six items, yielding a total summed score ranging from 0 to 600.
Greater scores on the EBI reflect a deeper, more complete sense of psychological resolution and catharsis.
