E. Caffeine

Explanation: caffeine abuse or addiction is a form of addiction whereby excessive and/or harmful amounts of caffeine is consumed. Because caffeine is a widely legal and accepted stimulant, most people do not believe it can be abused or that it is addictive. Although most people get their caffeine intake from coffee, many other products (food,drinks, confectioneries) contain caffeine and most people consume more caffeine than they assume.

Caffeine addiction leads to a variety of symptoms associated with the brain and nervous systems such as;

chronic insomnia, jitters, irritability, muscle twitches, flushed face, stomach upset and increased heart rate.
