Oregon is on track to become the first US state to role out legal psilocybin, the psychoactive substance found in “magic” mushrooms. Officials are now tentatively planning to green-light one particular species of “magic” mushroom for therapeutic use in the state starting in 2023.
Jessie K. Uehling, a mycologist and member of Oregon’s Psilocybin Advisory Board, told Insider that Oregon is focusing on a species called Psilocybe cubensis because it’s widely cultivated and easy to grow.
While almost any species of magic mushroom can be grown, Psilocybe cubensis in particular grow very fast with “pretty good yields,” said Alan Rockefeller, a mycologist based in Oakland, California.
Unlike a handful of other “magic” mushroom species, including those that grow in the Pacific Northwest, Psilocybe cubensis isn’t associated with wood-lover’s paralysis, according to Uehling.
Not every mushroom expert agrees with Oregon’s decision to hone in on one “magic” mushroom species.
Rockefeller told Insider that he believes people should be able to choose which species they take.
“Out of about 200 mushrooms, there’s maybe four of them that cause wood-lovers paralysis,” he said.
“I think the Oregon thing is still good. But if I was in charge, I wouldn’t have restricted it to just one species,” Rockefeller, who is not on Oregon’s advisory board, added.
No matter the species, growing “magic” mushrooms is relatively cheap.
“It costs about the same amount to grow psilocybin mushroom as it does to grow the mushrooms you see in the supermarket,” Rockefeller said, referring to all “magic” mushroom species.
