Psilocin (also known as 4-HO-DMT, 4-hydroxy DMT, psilocine, psilocyn, or psilotsin) is a substituted tryptamine alkaloid and a serotonergic psychedelic substance. It is present in most psychedelic mushrooms[3] together with its phosphorylated counterpart psilocybin. Psilocin is a Schedule I drug under the Convention on Psychotropic Substances.[4] Acting on the 5-HT2A receptors, psilocin modulates the production and reuptake of serotonin.[5] The mind-altering effects of psilocin are highly variable and subjective and resemble those of LSD and DMT.
