Caffeine is the most common stimulant. Caffeine is the most widely used drug on the planet and has been used for centuries for its stimulating effects. Most energy drinks contain between seventy to two hundred milligrams of caffeine each. For example, a full can of Rockstar contains one hundred sixty milligrams of caffeine. Caffeine stimulates the central nervous system, which gives the body a jolt of their senses, making them more alert. The use of caffeine can dehydrate the body and raise blood pressure and heart rate.
