Why does chewing betel nut become addictive?

The main reasons why betel nut consumption can lead to addiction are as follows: 1. Effect of Arecoline: Betel nut contains a unique component called arecoline. It has a stimulating effect on the human nervous system, increasing neural excitability and may even numb the nerves. With long-term intake of arecoline, the nervous system gradually becomes dependent on this stimulation, leading to addiction. 2. Additional ingredients: Some betel nut products also contain ingredients such as ephedra, mint, and Radix Asari (Chinese magnolia vine root). These components may further enhance the stimulatory effects of betel nut on the nervous system, accelerating the development of addiction. It is recommended to avoid long-term and excessive consumption of betel nut in order to prevent adverse effects on health.
