Several people rely on caffeine to wake them up or give them a boost of energy when they feel down. Acting as a stimulant, caffeine not only improves concentration and focus, but also stops fatigue (Staff 1). Considered the most commonly used psychoactive drug in the world, approximately 90 percent of adults consume it daily (“MedicineNet.com” 1). But do caffeine buyers really stop to evaluate the possinle harmful effects on their body? Health scares similar to this are not recent. In fact, they have been going on for over 100 years. In 1911, the US Government sued the Coca-Cola company for making their drinks hazardous to other’s health (Lovett 2). Although the Coca-Cola company won, it proves that people worry about what they put into their bodies, even if it does help them stay up to finish their homework. Not everybody will experience the same effects from caffeine. Some people seem more sensitive to caffeine than others (Staff 1). While some will express unwanted effects after only one cup of coffee or tea, others will not notice these same effects until after maybe four or five cups. Although caffeine does include benefits, many downfalls exemplify the stimulant as well. Drinking even small amounts of caffeine daily develops harmful effects on most people’s body and health.

Scrutiny of caffeine and its effects has increased dramatically in the last 20 years, due in part to an increase in consumption of caffeine. In fact, coffee consumption among young adults rose to 3.2 cups per day in 2008 from 2.4 cups per day in 2005 (Rokerya 1). For instance, in a one hour period, on Richland College’s on-campus Starbucks, the author took note of how many customers arrived and purchased a cup of coffee. Between 8:00 and 9:00 AM, there were 51 customers, implying that – especially at college - many people are dependent on coffee in the mornings.

Coffee is the first thing that people associate with instant energy on a groggy morning. “In the U.S., coffee is king of beverages” (Reinke) Research has been done that has named coffee as an addiction to the people who consume large quantities of it. Coffee was named the top source of antioxidants. This is partly because of the amount consumed each day. Some of the antioxidants that coffee has are quinines and chlorogenic acid. It also contains trigonelline, an antibacterial compound. This is where coffee acquires its delicious aroma. Now let’s step back for a minute and just think about how much caffeine people consume. In an 8oz cup of coffee it has about 85 milligrams of caffeine. This is about double the amount that tea contains. Studies have shown that caffeine stimulates the brain and nervous system. This is where you get that energized feeling. After about the third cup, knees start to bounce, pens are clicking and people start running laps around the office. Caffeine can become addicting if you drink too much. Coffee can become that addictive habit people are unable to shake.
