Ancient Humans Used Betel Nuts to Get High 25,000 Years Ago

Topic: Biology

Scientists found evidence that people in Indonesia used betel nuts as a drug around 25,000 years ago. This is much earlier than previously thought. The researchers studied ancient teeth and biochemistry to reach this conclusion.

Archaeologists from Griffith University discovered that humans were using mind-altering substances much earlier than scientists believed. They found evidence of betel nut use in Indonesia dating back around 25,000 years ago. This is a significant discovery because it challenges the idea that people only started using psychoactive drugs during the Neolithic period, about 3500 years ago.

The researchers studied ancient teeth and biochemistry to reach this conclusion. They found that some communities in Indonesia were using betel nut as a drug much earlier than previously thought. Betel nut can produce mild euphoria, increased alertness, and other psychoactive effects. It is the world's fourth most widely used psychoactive substance, after alcohol, caffeine, and nicotine.

The researchers also discovered that people were sucking on whole betel nuts to get high, rather than just chewing them with slaked lime. This was a new behavior that they identified through their research. They conducted experiments in which they soaked betel nuts in artificial saliva and tested the resultant broths against human receptors. This showed that simply sucking on intact betel nuts can release arecoline, a neuroactive alkaloid, in sufficient amounts to have a physiological effect.

The study was led by Professor Adam Brumm of Griffith's Australian Research Centre for Human Evolution (ARCHE). He worked with Indonesian archaeologists from Makassar's University of Hasanuddin and the National Research and Innovation Agency (BRIN). The researchers published their findings in Science Advances, a journal that publishes research on scientific breakthroughs.

Why It Matters

This discovery is important because it shows that humans have been using psychoactive substances for much longer than we thought. It also highlights the importance of understanding the history and origins of our behaviors and habits.
