Archaeologists found evidence in ancient bones

Australian researchers examined two old skeletons that showed deep grooves on their teeth. They believed these marks resulted from repeatedly sucking on whole nuts. Chemical tests later confirmed the presence of arecoline inside those seeds.

The habit spread to China quickly

The nut arrived in China roughly 2,000 years ago and gained popularity fast. It served as a stimulant for commoners and a tribute for emperors. Today it remains one of the most widely consumed psychoactive substances globally.

Users consume it with lime powder

Modern preparations combine the nut with slaked lime and other ingredients. This mixture ranks among the top psychoactive substances after caffeine, alcohol and nicotine. About 600 million people use this substance across many regions.
