caffeine
Adenosine receptor blocker
Caffeine is a stimulant compound found naturally in coffee, tea, and cacao, and added to soft drinks and energy drinks.
It works by blocking adenosine receptors in the brain, reducing drowsiness and increasing alertness.
Most adults consume caffeine daily, making it the world's most widely used psychoactive drug: I can't function without my morning caffeine.
Caffeine withdrawal can cause headaches and irritability.
