Plants and fungi have spread throughout the world, the consumption of which produces visions and hallucinations in humans, accompanied by profound emotional and intuitive states, which are illuminating and revealing. On all five continents there have been and continue to be cultures that use these particular plants as an instrument to transcend ordinary reality and to communicate with the world of spirits and gods or the afterlife.

Those peoples whose culture and religion have been subject to the phenomenon of syncretism with external religions - such as Christianity, Islam and Buddhism - have developed and adopted their mythology through a process of symbolic superposition and comparison that is reflected even in the origin myths of psychoactive plants.

As a researcher in the multidisciplinary field of human use of psychoactive plants, I have tried to organize and offer a set of mythological materials - most of them unpublished - with the idea that we can read consecutive stories about the origin of marijuana, tobacco, peyote, fly agaric, mandrake, etc.
