Caffeine Critical Evaluation

With this being said, the author includes this in his essay because he wants to show that it is possible to go without caffeine, but people consume caffeinated drinks in order to feel awake, alert, and focused.

He does this to show that caffeine has a healthy and safe effect on one’s body, and because of this, “caffeine is such a wonderful stimulant” (250). Therefore, Gladwell effectively incorporates historical figures and scientific knowledge in his essay in order to give strong evidence, and it would be difficult for people to argue against why caffeine has a beneficial impact on

With more than 300 disorders listed in the DSM 5, many without a clear biological etiology, it is easy to understand why a number of mental professionals now claim that the overmedication of patients has become a concern and that this practice needs to be reevaluated. The Manual for Mental Disorders is an indispensable tool used by psychiatrists, counselors, the courts, insurance companies and others as a reference guide to identify mental disorders and their symptoms.

According to the NIMH, the DSM “diagnoses are based on a consensus about clusters of

The effects of caffeine based energy drinks on cognitive and physiological function in first year undergraduate students. Introduction: Caffeine is a naturally occurring substance that acts as a neurotoxin and stimulant to the body. When orally consumed, caffeine is near fully absorbed into the blood and body tissues 45 minutes after ingestion and has a half-life close to 4 hours (coffeandhealth.org). When consumed in moderate doses it can masks fatigue and can alter an individual’s perception to be less sleepy and to obtain a heightened sense of alertness.

Caffeine is a chemical found naturally in few plants all over the world. From these plants it is processed into its pure form and then put into other things such as soda, energy drinks, tea, and pills. Energy drinks and soda are some of the most widely marketed products in the world, even though they contain the highest concentration of caffeine outside of pure caffeine supplements.

According to Levinthal (2012), substance dependence is defined as an individual physically depending on a controlled substance. Individual’s portrays various signs indicating a dependency problem. The DSM-IV measures dependency based on criteria within a twelve month time frame (Levinthal, 2012). Substance dependence can be rather disturbing to an individual when dealing with the side effects.

Caffeine has become a nationally used form of a pharmacologically active substance (PAS) (Pray et al., 1). PAS is defined by the World Health Organization as “any substance or combination of substances used as a pharmaceutical product” intended to alter the physiologically activity in the human body (“Definition of Active Pharmaceutical Ingredients”). Due to the effects that caffeine has on the body, it is classified as a type of medical drug. However, caffeine may not be a healthy coping mechanism for individuals.

Whenever a consumer uses an energy drink a series of effects begin in his/her body. The organism receives an instant boost as the caffeine successfully manages to block the duties of the adenosine, a chemical located in the brain whose function is involved with sleeping. After the completion of the process caffeine forces part of the neurons in the brain to lighten up, which later on causes the body to release the hormone adrenaline. When the hormone is active it forces the liver to provide the bloodstream with additional

But do people realize when they take that sip of coffee, or bite into that bar of chocolate they are contaminating their body with what could be a very dangerous drug?
