In the world today, Nicotine is one of the most frequently used addictive drugs. The impact it has on society is like no other. It is one of more than 4,000 chemicals found in the smoke of tobacco products such as cigarettes, cigars, and pipes. This addictive drug is the primary component in tobacco that acts on the brain.
Tobacco can be found two ways, it can be dried brown leaves of various sizes or it can be a grown form of tobacco. When extracted from the leaves, nicotine is colorless, but quickly turns brown when exposed to air. It then becomes a poisonous, pale yellow, oily liquid with a pungent odor and acrid taste. The amount of nicotine contained in tobacco leaves ranges from 2% to 7%. There are four ways in which you can use tobacco. They are cigarette smoke, dry or wet snuff, and chewing tobacco. The cigarette smoke is inhaled through the mouth. Most cigarettes in the US contain 10 milligrams or more of the nicotine. Since most of the nicotine is destroyed by the heat of burning the actual concentration of nicotine in smoke is low. So, when inhaling the smoke you actually only take in 1 to 2 mg of nicotine per cigarette. Nicotine is absorbed through the skin, lining of the mouth and nose, or by inhalation in the lungs. Depending on how the tobacco is taken, nicotine can reach peak levels in the bloodstream and brain rapidly. Cigarette smoking, for example, results in quick dis...
Nicotine is a highly toxic substance (LD40) which can affect the brain, central and autonomic nervous system
During the time period 1450 to 1750, the world went through major change and development. Nomadic power declined, and European Kingdoms became world powers. A world trade network was set up as contact amongst nations increased immensely. A population boom occurred throughout the world. Many civilizations that were once isolated were brought into the world economy. The Americas unknown until Christopher Columbus’ voyage in 1492 became a major part of the world economy as many European nations colonized much of the land. Large sea trade arose during this time period first by the Portuguese and Spanish and later by the English, French and Dutch. As European countries began exploring the Americas, an exchange of crops, animals, raw materials, diseases and new ideas were exchanged between the Americas and the rest of the world. This is known as the Columbian Exchange. One major component of the Columbian Exchange was the discovery of tobacco. Tobacco was first discovered in the Americas and became as cash crop. It was imported back to Europe, where it became vastly popular. As many middle class Europeans people began smoking, the demand for more tobacco from the Americas increased; colonies were set up to produce tobacco. With the demand for tobacco so high, labor was needed to farm the crop causing slaves to be imported.
Throughout the book, the conflict between the mothers, their Chinese tradition, and language and the daughters, their American tradition, and language are evident. Suyuan and Jing-Mei Woo are mother and daughter, respectively, who are characters that illustrate the conflict between the two cultures.

Nicotine (C10H14N2) is one of the most common and addictive of substances used in daily life worldwide. Chemically, it is a yellow-brown, soluble liquid that has a peculiar fish-like odor and a “MSD hazard diamond classification of 3 for health, 1 for flammability, and 0 for reactivity”(ScienceLab.com, 10/10/05). It is a chemical most commonly found in cigarettes, which combines the nicotine with tobacco. The nicotine in the cigarettes is what causes them to become addictive. Addiction is described as “a dependency or chemical imbalance in the brain that cause people to have no control of their actions where the addiction is involved” (Nordqvist, March 2009). A person can get addicted to anything such as gambling, alcohol, and nicotine. In 2011, it was collected that “38.1% of American adults smoke, with 21.6% being adult men and 16.5% being adult woman” (According to the Center for Disease Control and Prevention). In a whole, Nicotine can have harmful effects on your nerves and senses like addiction, but can also make you feel happy, assertive, and concentrated. So is it worth the risk? Or does Nicotine do more harm than good?
Encyclopaedia of Children’s (2013) stated that smoking is a form of inhalation of smoking from different forms of tobacco which include cigarettes, pipes, and cigars. Cancer Research (2012) and the World Health Organisation (2013) have confirmed that most tobacco products contain very high level of nicotine which can have additive effect and are made from tobacco leaf which are s...
Smokeless tobacco includes two main categories, which are chewing tobacco and snuff. Chewing tobacco is typically composed of loose tobacco leaves, and snuff is ground up tobacco leaves that can come dry, moist, or in pouches. The nicotine in this drug enters through mouth tissue. According to the CDC, in 2012 about four in every 100 adults used smokeless tobacco (Centers for Disease Control and Prevention, 2015). Some of the damaging effects on the body are tooth loss, cavities, and decay, bone loss at the roots of teeth, mouth lesions, receding gums, and hypertension. Smokeless tobacco also causes many forms of cancer like mouth, gum, and esophageal cancer, as well as heart disease, stroke, leukoplakia, etc. (American Cancer Society, 2013). Contrary to some viewpoints, smokeless tobacco is not a safe alternative to smoking. Both tobacco products are detrimental on the body. There are more deaths associated with cigarette smoking than with smokeless tobacco use, however both forms of tobacco cause harm on the body and death (American Cancer Society,
The most common form of tobacco used is the cigarette. Smoking for most people gives satisfaction and pleasure. The tobacco chemicals that are released into the brain when inhaled cause a happy or joyous feeling to the person. People often turn to cigarettes to suppress hunger or relieve stress (Dichter). After a short period of time, a person can become addicted to the satisfaction they get from smoking a cigarette. Certain tobacco products contain toxins, carcinogens, and poisons that are all extremely harmful to the human body. 60 chemicals that are contained in a tobacco cigarette are cancer-causing agents (Wexner). It is these chemicals that make cigarettes as well as other tobacco products so addicting to their users. Over time the need for a cigarette increases and the harder it becomes to quit smoking. Some users turn to smoking alternatives in order to quit. The first thing a smoker will reach for is something that looks and feels similar to a normal cigarette.
Cigarette addiction is responsible for over four million deaths every year. The question most people ask is why don’t people just put down their cigarettes? Well, the answer to that often asked question is nicotine. Nicotine is a neurotransmitter that targets certain receptors in the brain. It is a chemical messenger that induces feelings of pleasure. When someone takes a hit off of a cigarette, they ingest the harmful chemicals that can cause cancer and other serious health threats. They only inhale these chemicals to get one thing and one thing only, nicotine.
When people use tobacco product the nicotine quickly enters into the human blood stream. Shortly ten minutes after entering into the body the nicotine than reaches the brain which release adrenaline. Nicotine chemically changes the brain in a similar way to heroin and cocaine, so it’s no wonder so many tobacco users have a hard time quitting!
The governments must ban the sales of tobacco products. There are many consequences to smoking like health, addiction, cessation and economic costs. Second hand smoke is a major problem, since smoking is allowed in alot of public places.
Smoking cigarettes is a very deadly addiction that, unfortunately, affects 42.1 million adults in the United States and 6.4 million children. The reason why so many people get addicted to cigarettes is because of nicotine. Medicinenet.com says that nicotine is “made by the tobacco plant or produced synthetically”. Nicotine has powerful pharmacologic effects (including increased heart rate, heart stroke volume, and oxygen consumption by the heart muscle), as well as powerful psychodynamic effects (such as euphoria, increased alertness, and a sense of relaxation). Nicotine is also powerfully addictive.”

There are many causes which make people smoke, however it can be divided into two main causes: physical and psychological. First cause which is physical concerns the human body’s needs. Nicotine contained in cigarette is an addictive substance. It is the chemical which causes addiction. Nicotine reduces tension in the muscles and allows smokers to relax so they feel that they can relieve stress by smoking. Nicotine can also have a calming effect on people who are anxious and worried. This is why it can bring a feeling of tranquility and help smokers to cope with stress. Thus, people smoke when they are depressed, lonely or bored. Nicotine is absorbed by the smoker’s lung and intestines. Very quickly, nicotine can stimulate brain and certain types of nerves so heart rate and blood pressure go up; respiration increases. A little nicotine makes smokers feel more energy and improve concentration. As a consequence, these physical effects created by smoking play an important role in making people feel the need to smoke.
(Junior Scholastic, 2006) When you utilize tobacco products, nicotine is expeditiously absorbed into your bloodstream. Within 10 seconds of entering your body, the nicotine reaches your brain. It causes the brain to relinquish adrenaline, engendering a buzz of pleasure and energy. The buzz fades expeditiously though, and leaves you feeling tired, a little down, and wanting the buzz again.
