Although it remains a large portion of the U.S’ economy, tobacco smoking can lead to a variety of diseases and disorders that affect the user. The effects of smoking tobacco not only affect the user but surrounding people as well: permanently destroying their lungs and children, increasing the chances of diseases and of cancer.

The nicotine drug is “a toxic colorless or yellowish oily liquid that is the chief active constituent of tobacco” (Definition of Nicotine in English). This means that it is dangerous (harmful to health), and is the main ingredient in cigarettes. Dr. Ananya Mandal, MD, says “Nicotine is a chemical compound that is present in tobacco. When tobacco is smoked, nicotine is absorbed through the wall lining of the small air sacs in the lungs. When sniffed or chewed, it is absorbed through

The intake of Nicotine is unhealthy and may produce symptoms that affect the users overall health. The way nicotine is entering the body

Tobacco is a nervous system stimulant that triggers complex biochemical and neurotransmitter disruptions. It elevates heart rate and blood pressure, constricts blood vessels, irritates lung tissue, and diminishes your ability to taste and smell (Health).

A Tobacco plant is made up of approximately 5 percent of nicotine by weight. There are two categories of tobacco products cigarettes and smokeless tobacco. Nicotine has many effects on the body but the effect it has on the brain is responsible for the so called “good feeling” that is behind the addiction. Nicotine is considered to be addictive because of the psychological and physiological effects on a person. The Center for the Advancement of Health published the results of a study on teenager smokers:

Nicotine is an addictive drug, as addictive as heroin and cocaine. It is found in small amounts in certain plants, but mostly found in the tobacco plant. A per- son gets nicotine into his or her system through either smoking or smokeless tobacco.

Nicotine is a chemical produced in some plants, one plant being the tobacco plant. “There is considerable evidence that nicotine is present in certain human foods, especially

Most cigarettes have eight to nine mg of nicotine, though only one mg is transferred to the smoker. Nicotine increases the heart rate, raises the blood pressure and causes blood clotting to the smoker. The most important fact about nicotine is that it has no medical value. Other drugs like marijuana, heroine, and cocaine have no medical value as well but for some reason, cigarettes are legal in the US. An interesting fact that many people do not know is that nicotine, the addicting drug in cigarettes, is more addicting then marijuana, heroine, and cocaine. There has not been one reported death due to marijuana. In 1988, the U.S. Surgeon General reported that nicotine is just as addictive as heroin and cocaine. A "hit" of nicotine reaches the brain in seven seconds, twice as fast as heroin injected into the vein. And still the cigarette is still legal.

Nicotine is a psychoactive, stimulant, toxic drug and when tobacco users smoked cigarettes and tobacco products, the toxic chemical goes into the lungs and absorbs

     The large particles in cigarette smoke, commonly known as “tar”, collect in the branching points of the lungs. The tar contains carcinogenic compounds that increase the risk of lung cancer. The small particles in cigarette smoke, including carcinogens, irritants, and corrosive chemicals, collect in the small air sacs in the lungs and damage them. These air sacs are where the blood absorbs oxygen from the air. When the small particles from the cigarette smoke are absorbed into the blood

Nicotine has a powerful addicting effect because it is absorbed rapidly into the pulmonary circulation following inhalation from which it passes through the left side of the heart and into the cerebral circulation. It rapidly crosses the blood-brain barrier and binds to specific receptors in various parts of the brain. Stimulation of receptors by nicotine results in the activation of a number of neurohumoral pathways leading to release of acetylcholine, norepinephrine, dopamine, serotonin, vasopressin and various hormones. Nicotine causes the release of the substance b-endorphin, an endogenous peptide that also binds to opiate receptors. This indicates a link between addiction to opiates, such as morphine and heroin, and addiction to nicotine.

Additionally, nicotine tightens the blood vessels which slows down blood flow. The health effects of smoking are frightfully damaging and in many cases, deadly. The chemicals in tobacco smoke are breathed in into the lungs and then travel throughout the body.

A conversation is normally started as a smoker asks for a light or a cigarette. In addition, it is also difficult for a person to quit his/her friends whom they smoke together. Some of the long-term effects of smoking include sleep disorders irritability, lack of concentration severe headaches and anxiety. Pure nicotine is said to be extremely poisonous and it can cause death. Currently, use of nicotine is said to be causing the highest number of deaths in the United States. It causes
