Caffeine

Caffeine is the world's most widely consumed psychoactive substance, prized for its ability to increase alertness and reduce fatigue. It primarily works by blocking adenosine receptors in the brain. Adenosine is a neurotransmitter that promotes relaxation and sleepiness; by inhibiting it, caffeine increases neuronal firing and stimulates the central nervous system. This action also indirectly boosts levels of other neurotransmitters like dopamine and norepinephrine, which contributes to its effects on concentration, wakefulness, and mood. Found in coffee, tea, and soda, caffeine can improve reaction time and motor coordination, though high doses can lead to anxiety and disrupt sleep.
