Summary:
- Researchers discovered evidence of psychoactive substance use in 25,000-year-old human teeth found in a burial site in Menorca, Spain.
- Chemical analysis of dental calculus revealed the presence of alkaloids such as ephedrine and atropine, suggesting that ancient populations intentionally ingested plants with stimulant or hallucinogenic properties.
- The findings provide significant new insights into prehistoric medicinal practices and the ritualistic or recreational use of psychoactive flora in hunter-gatherer societies.
