According to an article from Caffeine Informer(2010), caffeine intoxication is now included in the DSM-5 physicians manual.The official diagnosis can be made when any 5 of the following symptoms are present: restlessness, nervousness, excitement, insomnia, flushed face, diuresis (you keep passing urine), gastrointestinal disturbance (upset tummy, diarrhea), muscle twitching, rambling flow of thought and speech, tachycardia or cardiac arrhythmia, periods of inexhaustibility, or psychomotor agitation. In 2010,a 23 British man from Mansfield, England died after taking to 2 spoonfuls of pure caffeine powder washed down by an energy drink at a party. His death was ruled accidental.
From an article published in the website “www.caffeineinformer.com”(2010), caffeine is the world’s most frequently used stimulant and perhaps, the most popular drug. Beverages and foods containing caffeine are consumed by almost all adults and children. The average daily intake of caffeine is approximately 200 mg (the equivalent of almost 2 cups of coffee), with as many as 30% of Americans consuming 500 mg or more per day. The most common sources of caffeine includes coffee beans, tea plants, kola nuts, mate leaves, guarana paste and yoco bark. To understand the unique role that caffeine plays, it is useful to gain perspective on its common sources which is unfermented beverages. Some of the beverages in the amount 5oz contains the following caffeine content. Brewed coffee (90 to125 mg), Instant coffee (35 to164mg), Decaffeinated coffee (1 to 6 mg), Tea (25 to125 mg), and Cocoa (5 to 25 mg).

... the exact amount of caffeine consumed in a day. The size of the cup/serving varied from 25 ml (Greek coffee) to 330 ml at home and from 130 ml to 280 ml in the out-of-home situation.
According to an article from Caffeine Informer entitled “Caffeine Metabolism”, it would take 45 minutes for 99% of the caffeine content to be absorbed through the membranes of the body. Furthermore, it was said that the half-life of caffeine for humans is ranging from 2.5 to 4.5 hours, denoting that the average coffee’s effect lasts about 2 to 3 hours. It was also stated that caffeine is most studied for its ability to work similarly with adenosine, the sleep-wake cycle molecule found in the brain. When adenosine binds to enough receptors, it signals the brain that it is time for rest but what caffeine does is cover up the drowsiness symptoms that adenosine can no longer produce.
Caffeine, a central nervous system stimulant, is the main psychoactive ingredient in energy drinks, which enhances alertness and mood, and counteracts symptoms of sleep. There is no doubt ...
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 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 also increases dopamine levels in the same way that amphetamines do (heroine, and cocaine also manipulate dopamine levels by slowing down the rate of dopamine reuptake). Dopamine is a neurotransmitter that, in certain parts of the brain, activates the pleasure center. Caffeine’s effects are obviously much lower than heroin’s, but it is the same mechanism. The long term problem with caffeine is the effect it has on sleep. The half life of caffeine in your body is about 6 hours. That means that if you have a big cup of coffee with 200 mg of caffeine in it at 3:00pm, by 9:00pm about 100 mg of that caffeine is still in your system. You will still be able to fall asleep but your body is going to miss out on the benefits of deep sleep. The next day you are probably going to feel worse, so to make yourself feel better, you will need caffeine as soon as you get up and out of bed. This cycle can start to continue day after day. This is why 90% of Americans consume caffeine everyday. Once you get in the cycle, you have to keep taking the drug (home.howstuffworks.com).
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. (Chawala) Caffeine has been proven to have positive effects on an athlete’s performance, and ones overall 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. However, the results from these studies are inconclusive and often somewhat contradictory – many studies (such as that by Tetsuya Ohara et al.) show that caffeine is a great boon to
The idea that coffee stunts growth is a myth; hereditary determines a person 's height, and coffee provided benefits for an individual 's health. Although adding coffee addictions such as sugar and creamer detracts from coffees commendable health effects would not be beneficial. This brown, liquid, hot fresh beverage has proven through various studies and experiments, why individuals must drink coffee everyday. As stated before, over half of all Americans drink coffee everyday, with the population’s height growing every year. Perhaps, as years progress the height will keep getting towering, making the myth
Most people aren’t aware that caffeine can act as a stimulant to the central nervous system. So once someone consumes a caffeinated beverage they may begin to notice a slight change in the way their body begins to feel. Caffeine can be found in many different places such as energy drinks, coffee, candy and also in other common beverages and over the counter medications. Caffeine can have major side effects on those who consume it on a regular routine, but caffeine can also have side effects on those who rarely even consume caffeine . “These side effects include sleep deprivation, nausea, cramping, anxiety, fatigue, and headaches (Braun 73).” Not only does drinking a couple of caffeinated beverages come with its list of side effects, caffeine consumption has also been proven to show drastic changes in the kidneys. “Also, caffeine has been known to weaken the detrusor muscles in the bladder, which provokes the need to urinate (Chambers 42).” So once a person has been consuming caffeine past a certain period of time it begins to become difficult for them to regulate their trips to the bathroom. The list of harm caffeine does on the human body could continue forever, but I will review some of the most relevant categories. Caffeine can have harmful effects on the human body that people are not aware of, therefore I believe that people should be informed what exactly caffeine is and how it affects them directly in terms of where caffeine can be found, the effects it has on the brain and the heart and also the pregnancy effects. Also, people should be provided with a general knowledge of how caffeine can play a part in someone’s life, and some steps to help slow down the consumption of caffeine.
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...
In the United States, coffee is the second largest import (Roosevelt, 2004). Furthermore, the United States, consumes one-fifth of all the worlds¡¦ coffee (Global Exchange, 2004). The present industry is expanding. It is estimated that North America¡¦s sector will reach saturation levels within 5 year (Datamonitor. n.d.). According to National Coffee Association (NCA), 8 out of 10 Americans consume coffee. In addition, it is estimated that half of the American population drinks coffee daily. The international market remains highly competitive. It is estimated that 3,300 cups of coffee are consumed every second of the day worldwide (Ecomall, n.d.). The latest trends included dual drinkers, an increase in senior citizens...
Caffeine is the single most widely consumed psychoactive substance in the United States (Einöther & Giesbrecht, 2013). According to Einöther and Giesbrecht (2013), 80% of the world’s population consumes caffeinated products every day, with coffee and tea being the primary sources. In the recent years, the demand for

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.
