Waking up with a hot cup of coffee, enjoying the cool tingling sensation of a cola during lunch, or winding down in the afternoon with a cup of tea, all have an ingredient similar to caffeine. Caffeine has been consumed since 2700 BC, in conjunction with tea, by the Chinese emperor Shen Nung. In 575 AD, the first use of coffee beans was in Africa, where it was used as currency and food. Even more so today, caffeine consumption has become an integral part of the daily lives of millions of people. According to David Weaver, "caffeine and theophylline are among the most widely consumed neuroactive substances. These drugs are consumed most frequently in beverages, but are also present in some over-the-counter diet aids, in "alertness tablets", in some preparations analgesics and in chocolate, and are also administered for therapeutic effects." The problem with caffeine is that many students/adults are not educated on this topic. Stereotypically, caffeine has been labeled as harmless. However, most caffeine users have no idea how it reacts to their body chemistry, chemical mechanisms, hidden side effects, and the actual daily amount they consume. “Researchers attempted to find out how much caffeine people consume each day. It has been estimated that in the United States, coffee drinkers drink an average of 2.6 cups per day. The total caffeine intake for coffee drinkers was 363.5 mg per day, including caffeine from coffee AND from other sources such as soft drinks, foods, and medications. Coffee drinkers also get a lot of caffeine: former coffee drinkers get about 107 mg per day, and people who do. have never drank coffee they get about 91 mg per day. (Schreiber et.
