Caffeine is a xanthine alkaloid, a central nervous system stimulant that temporarily repels drowsiness and restores energy. Caffeinated coffee, tea, soft drinks and energy drinks sell very well, so caffeine is also the most commonly used psychotropic drug in the world. In North America, 90% of adults use caffeine every day.
