Caffeine is the most widely consumed behaviorally active substance in the world making it one of the world’s most popular drugs.

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...

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.
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 does help you wake up and feel more alert and it has been shown to increase attention spans. This is a beneficial effect for people who are driving long distances and for people who are doing tedious work. Calling this a health benefit may be stretching it, though staying awake while you are driving a car definitely contributes to your well-being!

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.
