Mushrooms are fairly easy to find.
They are usually locally grown, in pastures, though some are artificially cultivated in greenhouses or plant aquariums. The medium for growth is manure, preferably the bovine kind. At low doses will cause a pleasant experience, relaxation, and altered body sensation, such as warmth or tingling. Higher doses will cause hallucinations and delusions such as believing that one is experiencing a mystical vision. Mushrooms are generally dried, although fresh ones are often more potent.
