Caffeine plays an enormous role in society today, from coffee to cokes to candy bars. Companies have made billions off the desire for that extra kick. Caffeine is the most widely consumed behaviorally active substance in the world making it one of the world’s most popular drugs. It’s known for the ability to stimulate the brain and central nervous system. The Chemical structure of caffeine is C8H10N4O2. Before the popular use of caffeine one can assume that people were sleepier, and less alert.
Consumption of 1000–1500 mg per day is associated with a condition known as caffeinism. Caffeinism usually combines caffeine dependency with a wide range of unpleasant physical and mental conditions including nervousness, irritability, restlessness, insomnia, headaches, and heart palpitations after caffeine use. Caffeine blocks the neurotransmitter adenosine, which acts as an inhibitor of the other neurotransmitters. “When adenosine flows normally through the brain, it slows down the brain and body… When adenosine is blocked, the brain and body become more alert and active (Marcovitz 33).” Caffeine from coffee or other beverages is absorbed by the small intestine within 45 minutes of ingestion and then distributed throughout all tissues of the body. Peak blood concentration is reached within one hour. The biological half-life of caffeine the time required for the body to eliminate one-half of the total amount of caffeine varies widely among individuals according to such factors as age, liver function, pregnancy, some concurrent medications, and the level of enzymes in the liver needed for caffeine metabolism. It can also be significantly altered by drugs or hormonal states. In healthy adults, caffeine's half-life has been measured with a ra...

...natural pesticide and an inhibitor of seed germination of other nearby coffee seedlings, thus giving it a better chance of survival. Caffeine has also been found to enhance the reward memory of honeybees, improving the reproductive success of the plant.
People are renovating new ways to use caffeine all the time. For example two Harvard undergraduates are working on new product called Energy Spray. This new idea is making it to be you don’t need to drink coffee, or an energy drink to obtain the caffeine to wake you up. They decided to make something that you can spray on skin that will be absorbed into your body. Containing water, caffeine, and amino acids this shouldn’t give you the caffeine rush, but giving you a natural feeling of being more awake. Caffeine has shaped everything for office work to physical work. Who knows what the world would be like without it.
Caffeine is a very interesting chemical. Caffeine is found in many places including coffee plant, tea leaves, kola nuts and cocoa (1). Humans then process these plants into food stuff that contains caffeine such as tea, coffee and chocolate. Caffeine is composed of 14 atoms with a molecular formula of C8H10N4O2. It is one of the few central nervous system stimulants still legal in most countries (2). The chemical name for caffeine is 1-methyltheobromine (2).

Caffeine (systematic name is 1,3,7-trimethylxanthine or 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione) which is produced in many plants such as coffee beans, tea, cacao beans. On one hand, it is widely used all over the world not only in the human’s dietary such as tea, coffee and chocolate but also can be the pesticides which can be deadly to the insects. On the other hand, caffeine can also harm human’s health in several aspects such as the central nervous system, which is the most common one, the heart rate and the respiration. However, caffeine can also make people feel excited, focus on one thing easily, and have clearly thoughts. For adults, people can have no more than 250 mg caffeine per day. If people who take more than 13-19 grams caffeine per day may be cause to death finally. There has a wide range of analyse approaches to analysis caffeine’s application such as Nuclear magnetic resonance, Chromatography, Gas ...
Many of you might be thinking to yourselves “I must be a drug addict if caffeine is a performance-enhancing drug.”. Caffeine can make you more alert and less tired. This is why many people with wake up in the morning and drink a cup of coffee. Stimulants like caffeine have been used since the times of the Roman gladiators.
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 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. Caffeine can be found on almost every street corner. There is a coffee place in just about every town. Sodas and coffee are found...
Caffeine Effects In The Brain Caffeine acts in a multitude of ways in the brain. The most recent studies explore the cooperative effects of adenosine and dopamine, as well as the increase in calcium in the interstitial fluid and possible accumulation of cyclic adenosine monophospate. The most popular discussions of earlier studies of caffeine demonstrate its antagonistic effects on adenosine receptors. While it has been reported that adenosine receptors are located throughout the brain, the various subtypes can be found in very specific areas. Studies have also shown that caffeine reactions in the brain are based on the localization of adenosine receptors, dopamine receptors, and the amount of caffeine.
On average, people will consume about 300 mg of caffeine a day through mostly coffee, soda, and tea (Villanova). Caffeine is an addictive substance that is considered safe enough to be sold with few to no restrictions. People of any age can go to a convenience store or coffee shop to get their daily dose of caffeine and become addicted without realizing it. With recently updated laws on the restrictions of buying tobacco products in Oregon, questions of other possible restrictions on substances have surfaced. The question of whether or not products containing caffeine should be restricted in order to protect younger consumers is not a new issue. Many people have debated over whether or not the process would be worthwhile or necessary.
Since some caffeinated beverages are promoted as "dietary supplements," instead of drinks, the U.S. Sustenance and Drug Administration (FDA) does not manage the wellbeing of the ingredients. This absence of regulation implies that makers are in charge of the security of ingredients, a large portion of which don't have logical proof sponsorship wellbeing or viability. Caffeine is common in diets worldwide. It can be found in coffee, tea, soda, chocolate, as well as other dietary sources. Because caffeine is such a part of daily life, you may not think of it as a drug; however, caffeine does alter performance, is addictive, and can be toxic, and even fatal at high concentrations. Caffeine is well known, around 80 percent
As the vast majority of Americans are addicted to caffeine, studies show that the effects during post-consumption, can be positive or negative depending on the amount and frequency of caffeine intake. As the demand for caffeine has increased, the caffeine industry has increased its amount of marketing and establishments to help aid this demand. Caffeine addiction can lead to serious health detriments and physiological detriments. It is evident that the primary reason for consumption of caffeinated beverages is due to positive effects, such as alertness. The media has an abundance of marketing to continue to illustrate this main effect. The media fails to project the negative effects of excessive caffeine intake. This literature review will illustrate how excessive caffeine consumption can be detrimental to one’s life, and how problematic caffeine use derives from conditioning by the caffeine industries.
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.
The following study will examine and provide research methods, results and conclusions about college students who consume caffeine energy drinks, alcohol or both to get an energy boost for one reason or another. Coffee which use to be the highlight of boosting energy and staying up late nights to complete homework assignments or study has taken a fall in the 20th century. The study will also point out the effects of the energy drinks and alcohol and the harm and health concerns that contribute to the students behaviors when consumed. The first study examines energy drinks and alcohol among college students and the fact that more students are consuming the product. The study is a web based questionnaire. The article “Caffeinated cocktails: energy drink consumption, high-risk drinking, and alcohol-related consequences among college students”, paints a good picture of the behaviors followed by drinking energy drinks and alcohol such as; heavy drinking, increased alcohol-related consequences, taken advantage of sexually, traveling with intoxicated drivers, getting injured or physically hurt, and those requiring medical attention. The second article “A survey of energy drink consumption patterns among college students” utilized a field research focus group of 32 to determine how much college students drink energy drinks including the benefits and the health issues. The energy drinks Red Bull, Amp, Monster, Rock Star, Rip It, Full Throttle, and Cocaine, just to name a few were created to give individuals a “Jolt” of energy with a combination of stimulants or “energy boosters” that include caffeine.
t’s the night before your big "end of the year" test and you are trying to study. Once you realize it is 1 am and you are still studying you decide to get something to drink to help boost your energy level. What do you think this drink is mostly going to be? Is it tea? Is it soda? Why do those drinks help us stay awake with that extra "energy boost"? The answer is caffeine. Caffeine is in a lot of things we eat and drink every day and you may not even realize it. It's important to be aware of what ingredients are in things you consume. Caffeine is a huge part of our daily lives and our intake often reflects our health status. To expand upon this, in my speech I will weigh both the benefits and detrimental effects of how caffeine can alter
Preview: The potential effects are related to the main ingredient in coffee – caffeine. Caffeine is a drug that stimulates the central nervous system that increases alertness and energy, but it is also very addictive.
“A variety of studies conducted over several decades have shown that caffeine helps people to stay awake (sometimes longer than they want to), enhances performance on mental tasks, improves hand-eye coordination, speeds up reaction time, and boost energy for muscular work, including sports and exercise (“The Facts about Caffeine”, Klosterman, 2006, 59). Despite the fact that caffeine seems to be a necessity for the majority of the American population, it also has various side effects that can be hazardous to our health. My personal belief, is that people shouldn't have to be reliant on caffeine as a daily source of energy. I personally don’t like the effects that it has on my body when I consume it. Experiencing the jittery feeling that’s followed by an unpleasant coating on my teeth, is enough for me to assume that there are many other factors to consider before becoming reliant on this drug. Rather than using caffeine as a source of energy and an aid to uplift one’s mood, I opt for better sleeping hours, exercise, and eating a high-energy foods diet. Incorporating these simple factors can mean the difference between caffeine consumption and it’s unwanted side effects and waking up well rested, with high energy and an
