What's happened
Analysis of bones from Sulawesi shows deep tooth wear and arecoline traces, suggesting foragers sucked on hard betel nuts thousands of years ago. The finding, published in Science Advances, indicates psychoactive chewing dates back at least 7,600–25,000 years and is a landmark in understanding early drug use.
What's behind the headline?
Analysis
- The reporting aligns multiple sources to build a narrative that betel-nut chewing predates farming and is a long-standing psychoactive practice.
- Direct quotes from Prof Adam Brumm are used to illustrate the interpretation of dental wear and the evolution of chewing practices.
- The piece contextualises the finding within the broader history of psychoactive substances and public health implications of quid chewing.
Implications for readers: This pushes back the timeline for drug-use origins and highlights how material culture (for example, dental wear) can illuminate ancient behaviours.
How we got here
Researchers from Griffith University analysed skeletal remains from Sulawesi, dating from 7,600–25,000 years ago. They found distinct dental grooves and traces of the psychoactive arecoline, linking betel-nut sucking to early forager behaviour and challenging the view that drug use began with farming.
Our analysis
BBC Business reports the 25,000-year dating with Brumm’s interpretation; The Guardian provides broader context and direct quotes from Brumm; The Independent focuses on European Neolithic cannibalism, used here for contrast on how archaeology reveals diverse social practices.

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, but was not officially opened until 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. While Sir Samuel Griffith oversaw a violent period for Indigenous Australians due to his governments overseeing of the Australian Native Police, 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...
