American scientists managed to find traces of human activity at the Wishbone excavation site in Utah, which suggests the use of tobacco as an intoxicant during this period.

People could have started using tobacco more than 12 thousand years ago, and not 3 thousand years ago, as previously thought. The relevant conclusions of a group of American scientists based on archaeological excavations were published on the website of the journal Nature.

Scientists managed to find traces of human activity at the Wishbone excavation site in Utah, which suggests the use of tobacco as an intoxicant already during this period. In particular, charred tobacco seeds were found, which allowed the researchers to assume that the plant could have been burned to obtain the corresponding effect.

Next, scientists consider various ways that could have led ancient people to discover the psychoactive properties of tobacco in the process of domestication of plants. Researchers also suggest that initially, ancient people could not burn tobacco but chew its leaves and stems.
