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.

Complete Abstinence
Prazo: Baseline through 90-day follow-up (UG3) and 180-day follow-up (UH3)
|
Complete abstinence from methamphetamine (Timeline Followback, urine-confirmed); a dichotomous (yes or no) outcome where no use whatsoever during the assessment period is coded as "yes" and any use at all during the assessment period is coded as "no."

Craving
Prazo: 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
Prazo: 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.

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).
