Hunting psychoactive mushrooms in nature can be very dangerous.

Caution is advised because poisonous or deadly mushrooms can easily be mistaken for edible ones.

WARNING: Always start with lower doses due to differences between individual body weight, tolerance, metabolism, and personal sensitivity. The dosage below assumes that one is using dried Psilocybe cubensis and not pure psilocin or psilocybin as this is extremely uncommon. If you are using fresh mushrooms simply multiply weight by ten.

Psilocybe cubensis is a psychedelic mushroom in the genus Psilocybe. The primary psychoactive components of this mushroom are psilocin and its prodrug, psilocybin, as well as norbaeocystin and baeocystin.[1]


One research study showed that the level of psilocin was nearly zero in the first and sometimes the second fruiting of the mushroom and the level reached a maximum by the fourth flush.[2]
