Caffeine is Not as Addictive as Scheduled Narcotics
It is a common misconception that caffeine is a highly addictive compound. Caffeine does, however possess some mild stimulating properties. These properties are not enough to claim it an addictive substance, and definitely not a candidate to be a scheduled narcotic. “Today caffeine is greeted with near-universal approval and caffeine may well be the most commonly-used psychoactive substance on the planet”(Erowid). Caffeine is not as addictive as some claim when discussing the chemical effects and its addictive nature.
Caffeine, also known as trimethylxanthine, is a white stimulant drug in the xanthine alkaloid family. It has a crystalline structure and is bitter in taste. It occurs naturally in the seeds, leaves and fruits of some plants. Caffeine’s natural purpose is to act as a pesticide; however, caffeinated products were first consumed by humans as long ago as 3000 BC (Evans 2).
The most common form of caffeine consumption in the world is the drinking of coffee. According to a popular Ethiopian legend, called “The Legend of the Dancing Goats”, coffee was discovered by a goat herder named Kaldi. Kaldi noticed his goats frolicking around a green shrub with red berries and upon closer inspection he noticed the goats eating the berries. Kaldi was curious and decided to eat some of the berries himself, a short time later a monk from the nearby monetary noticed Kaldi and his sheep dancing in the field. The monk, being more scientifically minded than Kaldi, took some berries back to his monastery and roasted them to use in a drink and thus coffee was discovered. However, there is no way to prove the truthfulness of this story and it is thought by most to be simply...

By this definition, and after knowing the effects of caffeine upon the human body, I have come to the conclusion that drinking caffeine is a sign of a lack of respect for oneself, and of an unappreciative attitude toward the life that each of us has been blessed with. Furthermore, it shows of either our inability, or unwillingness to learn to think clearly.
Caffeine occurs naturally in some plants such as coffee beans and tea leaves. Caffeine is also added to other beverages.
Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are people who view caffeine as a helpful stimulant that increases the individual’s concentration and awareness as well as many other physical traits. The important thing to remember is that caffeine’s affects vary based on the person, the amount ingested, the frequency of consumption, and individual metabolism.

Caffeine is the most popular and most widely used stimulant in the world. In Canada, the average person drinks 2.6 cups of coffee a day; that is equivalent to 949 cups of coffee a year. (Van Houtte) Caffeine is a central nervous system stimulant that improves ones attention, focus, and fatigue. When caffeine is ingested it causes your neurons to move at a faster rate, increasing alertness. (Fit Day) Caffeine also binds to the neural receptors, which blocks the adenosine, which prolongs tiredness. Caffeine is a white odorless powder that is most commonly found in coffee, tea, energy drinks, and pops. Caffeine can also be considered and ergogenic aid. Ergogenic aids are external influences that enhance/ improves ones strength, endurance, reaction time and speed of recovery. (Healthline) The three theories that make caffeine an ergogenic aid during exercise is the effect it has on the central nervous system, skeletal muscles, and metabolic changes. (Sheila G. Dean) Caffeine also has a positive effect on an individual’s health, some positive effects include: reduces risk of developing liver cancer, Parkinson’s disease, and Alzheimer’s.

Does one drink caffeine? Caffeine is everywhere, it's in everything, it's apart of our daily lives. That’s what people doesn’t realizes; every soda drink, every cup of coffee, and every energy drink he or she gulps down before a thrilling game, all of that is caffeine. Caffeine is only completed when he or she get addicted. Caffeine can be an exceptional threat to the human body; energy drinks for example, it has enough caffeine to kill someone if he or she drinks enough. Energy drinks has been the number one drink high school students drink to stay awake in school; they even bring the drink in classrooms, and more than one energy drink.

Caffeine is a stimulant that has not been given the attention that some says it deserves. Caffeine is found in many everyday substances. It can be found in coffee, tea or sodas.

So, it is clear that addiction is all around us and can attack anyone of us at any given time. Even studies conducted show that people neglect to speak around their dependency for two primary reasons. Foremost, because people do not comprehend, or they bear a total misconception to their addiction, that they do not realize that addictions can be critical to their overall wellness. Moreover, second, many people believe being an addict will never happen to them, but, in reality, most addictions start off as simple little habits. Such as starting with one drink after dinner and before you know it you are drinking several drinks a day. However, one does not opt to be addicted to a substance, because addictions are physical defects in the brain, a disease, and not one’s choice.
The anti-reward system plays a major role in the occurrence of aversive effects in the body like jitteriness, and nausea; and is responsible for the negative-reinforcement that occurs through resumed drug taking. Negative reinforcement is responsible for bringing about the aversive effects that occur during withdrawal (i.e., when one intends to stop consuming the drug). This highlights the importance of the neuroadaptations that occur with prolonged drug use and can occur with over-consumption of caffeine (Meyer & Quenzer, 2005). In addition, caffeine can cause detrimental physiological effects, such as over-consumption.
Do you know what the most commonly used drug around the world is? It’s not cocaine nor marijuana, but surprisingly caffeine.
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.

On average, coffee drinkers in the Unites States drink 3.1 cups of coffee a day. Caffeine and fast food dominates our lives. About 90 percent of Americans drink caffeine whether through caffeinated beverages or cocoa.
