Psilocybin. 2011.
Another out of my sketchbook.
psilocybin mushrooms are a type of hallucinogenic mushroom, commonly known as magic mushrooms or sacred mushrooms, containing the compound psilocybin - a hallucinogen drug. Psilocybin-containing mushrooms are used both recreationally and traditionally, for spiritual purposes, as entheogens, with a history of use spanning millennia.
