Prehistoric High: 25,000-Year-Old Teeth Reveal Oldest Evidence of Psychoactive Drug Use

Researchers have discovered traces of arecoline in ancient teeth from Indonesia, providing evidence that humans may have used psychoactive areca nuts as far back as 25,000 years ago. This groundbreaking discovery pushes back the timeline of deliberate psychoactive substance use in human history by thousands of years. The findings suggest that the human desire to alter consciousness through plant-based compounds is deeply rooted in our evolutionary past. Understanding historical patterns of substance use helps modern researchers contextualize the role of psychoactive compounds in human culture and medicine.
