Jeff Shipley An Iowa lawmaker who’s been trying to legalize psychedelic mushrooms for medical use got a statehouse hearing on the idea early today, but Representative Jeff Shipley’s bill was defeated in subcommittee on a 0-3 vote. Shipley, a Republican from Fairfield, says psilocybin — the chemical found in so-called “magic” mushrooms — should be legalized as treatment for things like depression, addiction and end of life care. “I just want to thank everyone for coming out for a great discussion,” Shipley said this morning at the hearing. “I think that we’ve had some powerful testimony that there is indeed some medical value to these substances.”
