    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.

    A lot of people often wonder what caffeine is. When isolated in pure form, caffeine is a white crystalline powder that tastes very bitter. The chief source of pure caffeine is the process of decaffeinating coffee or tea. Caffeine is used to provide“boost energy” or a feeling of heightened alertness. It is often used to stay awake longer and late into the night. Many people feel as though they “cannot function” in the morning without a cup of coffee to provide caffeine and the boost it gives them. Caffeine is an addictive drug. It operates using the same mechanisms that amphetamines, cocaine, and heroin use to stimulate the brain. Caffeine effects are more mild than amphetamines, cocaine, and heroin, but it is manipulating the same channels, and that is one of the things that gives caffeine its addictive qualities. If you feel like you have to have caffeine everyday and cannot live without it, then you are considered addicted to caffeine.
