The 25,000-Year-Old Teeth That Just Rewrote The History Of Human Drug Use

The stimulant effect of arecoline is the reason betel nut is so widely used.

It creates alertness, suppresses fatigue, and produces a mild euphoria.

For people engaged in physically demanding labor — agriculture, fishing, construction — the fatigue suppression is valuable.

For people who need to maintain alertness under boring or taxing conditions, the stimulant effect is attractive.

For people who are hungry, the hunger-suppression effect is appealing.

The comparison to caffeine is apt: both are stimulant alkaloids that act through receptor systems in the brain to produce alertness and reduced fatigue.

Arecoline is generally considered to have stronger effects than caffeine and a higher addiction potential, though comparing across these compounds is complicated by the different ways they are consumed and the different populations that use them.
