What's happened
Researchers analyzing Sulawesi skeletons show that chewing psychoactive betel nuts dates back 25,000 years, suggesting early drug use among foragers. The study in Science Advances links distinctive dental wear to nut-sucking, offering the oldest evidence of psychoactive consumption and challenging ideas about when drug use began.
What's behind the headline?
Critical Analysis
- The story reframes when humans began engaging with psychoactive substances, pushing back the timeline to the Late Pleistocene.
- It underscores how dental wear can reveal behavior long after death, but causality remains debated among experts.
- The findings depend on experimental simulations; cross-validation with additional sites will strengthen confidence.
- Readers should consider how this shapes understanding of ancient social practices and ritual use.
Tone and method
- The analysis emphasizes concrete evidence (dental wear, arecoline traces).
- It relies on direct quotes from researchers and lays out experimental steps with clarity.
How we got here
The discovery centers on two forager skeletons from Sulawesi with unusual dental grooves. By testing regimens and saliva simulations, scientists demonstrate that sucking betel nuts releases psychoactive compounds, supporting a millennia-old habit that predates farming-associated intoxicants.
Our analysis
New York Post, BBC Business, The Guardian, Independent; all cite Griffith University researchers led by Professor Adam Brumm. The BBC and Guardian provide contextual background on how betel-nut chewing functions and its geographic footprint; the Independent contributes a European Neolithic perspective with broader implications for cannibalism studies.

Griffith University - Public university in south east Queensland, Australia
Griffith University is a public research university in South East Queensland on the east coast of Australia. The university was founded in 1971 and opened officially in 1975. The university has five campuses, at Gold Coast, Nathan, Logan, South Bank, and Mount Gravatt. A sixth campus, to be located at the Treasury Building in the Brisbane CBD, will open in 2027. The university was named after Sir Samuel Walker Griffith, who was twice Premier of Queensland and the first Chief Justice of the High Court of Australia. Sir Samuel Griffith played a major role in the Federation of Australia and was the principal author of the Australian Constitution, and his governments oversaw violent period for Indigenous Australians by involvement with Australian Native Police, but the University has since grown into a social value driven institution emphasizing equity, diversity and inclusion. The university offers undergraduate, postgraduate, and research programs across a range of disciplines, including business, law, science, health, education, engineering, and the arts. Griffith University was originally opened in Nathan, Queensland, as a single campus of 451 students, but has expanded to include five...
