Scientists decipher how a psychedelic substance is created, then engineer a plant to produce several at once

Long before scientists began studying them in the lab, mind-altering substances were already being gathered from plants, fungi and even animals for use in rituals, healing practices and mental health treatment.

Researchers at the Weizmann Institute of Science have now managed to bring together in a single organism five psychedelic substances that in nature are scattered across the tree of life.
