Psilocybin Cubensis is produced synthetically or extracted from the psilocybe mexicana mushroom and other mushroom species. It is chemically related to LSD. The drug is most often sold in the mushrooms themselves and are known by names like “psychedelic mushrooms,” “magic mushrooms,” and “‘shrooms.”
Usually taken orally, psilocybin is found in dried or fresh mushrooms or as a powder in capsules. It is sometimes brewed into a tea. Typical doses range from 4 to 10 milligrams, but are hard to control because the active amount of hallucinogens in mushrooms differ widely according to the genus, strength, and condition (fresh or dried) of the mushrooms.
Psilocybin spores are tiny one-celled reproductive units that have the capability to grow into fleshy, fruiting bodies of psychedelic mushrooms. You can find these hallucinogenic mushrooms growing on forest floors or rotting logs across the United States. (But it’s best not to eat what you forage unless you are a well-versed mycologist. Eating the wrong mushroom can be deadly.)
There are about 200 species of mushrooms within the genus Psilocybe, which contain psilocybin. They grow from spores, sometimes called psilocybin spores. There’s a good chance you can get your hands on them legally because psilocybin spores don’t actually contain psilocybin — a banned substance in the U.S. But growing them? Well, that is a different story.
Psilocybin doesn’t become present in the fungus until the spores germinate and begin producing mycelium. That’s the lace-like network of fungal threads. In the wild, mycelium grows underground or in rotting tree trunks and gives rise to mushroom fruiting bodies. As such, when psilocybin spores germinate and grow into mushrooms, they become illegal.
