Effects of Caffeine
Caffeine in its natural and synthetic form is found in a growing list of products such as coffee, tea, soda, energy drinks, chocolate, and some medicines. It acts as a central nervous system stimulant drug, having many pharmacological properties. It is considered the world’s most widely used psychoactive drug, but unlike other psychoactive drugs, it is legal. In 2010, the majority of Americans, 69%, said they consume caffeine in moderation. While the Food and Drug Administration deems caffeine as a generally safe food substance, lately, there has been much controversy about the potential health effects of caffeine. The increasing presence of caffeine in our daily lives poses the question whether or not health concerns are high enough to limit its consumption.
