Experimentální: 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.

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.
