Bronze Age Humans Got High on Psychoactive Betel Nuts

Researchers have discovered evidence of Bronze Age humans using psychoactive betel nuts as a recreational drug. By employing a new technique called "microattenuated total reflectance" (micro-ATR), they were able to analyze residues on ancient pottery shards, making the invisible visible. The study focused on ceramics excavated from a site in Thailand, dating back to around 2100-1500 BCE. The analysis revealed the presence of areca nut, the primary ingredient in betel quid, a chewable stimulant widely used in parts of Asia today. This finding suggests that the practice of using betel nuts as a psychoactive substance has ancient roots, predating its documented use by several centuries. The discovery provides a unique glimpse into the cultural and social practices of Bronze Age societies, shedding light on their use of mind-altering substances. The new analytical technique has proven to be a valuable tool in uncovering the hidden histories of human behavior and practices, allowing researchers to uncover the invisible past.
