Interactions

Alcohol is a depressant, not a serotonergic drug, so the co-use concern is additive impairment — and the 'drink less' idea borrows from full-dose trials.

Many antipsychotics block the 5-HT2A receptor psychedelics act on — a controlled study shows this can abolish psilocybin's effects. What it means.

Can you microdose on SSRIs or SNRIs? What the evidence says about blunted effects, serotonin-syndrome risk and why disclosure to a clinician matters.

What the published lithium + psychedelic case reports show — seizures documented, rate unknown, mechanism unclear — in one evidence table with sources.

MAOIs alter how the body clears psilocin and raise serotonergic load — a mechanistically high-caution interaction, though microdose incidence data are absent.

Mixing cannabis with a psilocybin microdose: a common pairing with thin evidence. What is documented, what is anecdote, and the risk signals.

A class-by-class map of how psychiatric medications can change psilocybin's risk, intensity, and interpretation — what the evidence shows and where it stops.

Serotonin syndrome is real and serious, but its documented incidence with psilocybin microdoses is essentially absent. Separating mechanism from measured risk.

Stimulants and psychedelics act on largely different systems, so the interaction is mostly theoretical — but the data are thin and the focus question needs care.
