The Effects Of Nicotine On The Human Body

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:

Smoking is the most avoidable cause of death. The drug nicotine is found in tobacco, and the most common use of nicotine is in cigarettes. Filter cigarettes are the popular form of nictoine in todays society, controlling over ninety percent of the U.S. cigarette market (Hart, Carl L., et al., 2013). Nicotine can be absorbed through the mucous membranes. Additionally it can cause, “lung cancer, cardiovascular disease, chronic obstructive lung diseases (including emphysema) (Hart, Carl L., et al.,2013). Nicotine can cause dependence, and often leads to smokers modify smoking patterns to acqire more nicotine. However, smokers are not the only people who suffer the consequences of smoke. Second handsmoke can cause lung

Fourth, e-cigarettes emit secondary exposure of nicotine within their range. In the study by Dr. Cheryl, e-cigarettes can cause secondhand smokers around the areas of e-cigarette users. The sample study showed that the e-cigarettes emitted 0.725 to 8.77μg/m3 of nicotine into the surrounding. Although the nicotine level of smoke from the conventional cigarettes has a higher number, e-cigarettes can still cause secondhand smokers (Marcham and Springston 7). The experts prepared a smoking machine that connects with the e-cigarette and a sample bag for measurement to conduct this specific study. These results were conducted by a group of experts to prove the harm of e-cigarettes usage in the indoor environment, supported by the American Industrial Hygiene Association (Marcham and Springston 24-25).

Nicotine is classified as a stimulant due to its ability to imitate acetylcholine. This particular function allows nicotine to both stimulate and block various nicotinic subtypes of cholinergic receptor sites. The blocking prevents information from being transported to the synapse, which prevents stimulation. It is also known that nicotine causes adrenaline to be discharged from both sympathetic sites and the adrenal glands. Ultimately causing nicotine to impact the body in a sympathomimetic manner. When inhaled the drug is capable of being absorbed rapidly, which is the reason why it is currently considered as one of the most toxic drugs. Symptoms associated with this drug include its ability to cause an individual’s heart rate and blood pressure to increase while reducing the amount of oxygen that is being delivered to the heart. The drug also stops hunger sensations by suppressing hunger contractions and damaging the taste buds.

Atmospheric nicotine is the vapour phase nicotine released during smoking. Considering the fact that nicotine has deleterious effect on human health, it has been recommended to stop using this substance in any form (smoking/chewing/e-cigarette). Toxicity of nicotine shows its effect not only on human health resulting in various types of cancers but also the surrounding environment including animals. The recent original research paper by Jingyan Yang etal [1], has measured the levels of vapour-phase nicotine present at various public places that included schools, hospitals, government buildings and entertainment avenues and compared the results with the baseline nicotine concentrations present prior to 2008. The study results have showed that

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

Smoking decreases the chance for a person to regenerate faster. The research’s states that the specific chemical Nicotine found in cigarettes stimulates the release of catecholamine’s which acts on the central nervous system causing vasoconstriction on blood vessels around the body (Sorensen,2012) which results in reduced red blood cell flow around the body which carries oxygen molecules that are in charge f metabolic rates of cells during the healing process of the body. Smoking also increases the chances of reduced stem cell proliferation, increase chances of infections (Giannoudis et al.,2007) and also an increased influence on intracranial atherosclerosis in patients with acute ischemic stroke (Ambrose and Barua, 2004).

To many individuals simply quitting smoking proves to be a bit more difficult that they might think. It is a weak mindset of the individual or is it something more than just going cold turkey. Looking a little deeper to the content of what cigarettes contain, one of its ingredients might have a better explanation as to why it might be so challenging to just give up smoking tobacco. Nicotine is an alkaloid that in its natural state it has a clear liquid appearance with a characteristic odor. When it is expose to air it changes its coloration to a brown color. Nicotine can be absorbed via oral mucosa as it is found on dipping and chewing products, as well as through the lungs as cigarettes, cigars, vaping devices and second-hand smoke. Nicotine can also be absorbed via the skin in a form of nicotine patches. Once nicotine is ingested, it’s absorbed and metabolized by the liver.

Jain and Mukherjee argued that ever since Posselt and Reimanbasic separated nicotine from tobacco in 1828, the studies in nicotine became rigorous and extensive (as cited in Jiloha, 2010, p. 3). Nicotine is a potent parasympathomimetic alkaloid pyridine ((1-methyl-2-[3-pyrodyl] pyrrolidine)), the proportion of its carbon, hydrogen, and nitrogen is C10, H14 and N2 which creates a structure that resembles a double-ring (Ashton & Stepney, 1982 as cited in Jiloha, 2010, p. 3). Nicotine has a molar mass of 162.23 g/mol, it is volatile and appears as an oily liquid that is miscible with water in its base form. When it has contact with light or air, it becomes brown in color and gives off a strong odor that people commonly associated as the smell

Every tobacco blends have one base kind, usually Virginia, Burley or Oriental one. These blends only makes up half of the cigarette, the rest is add in’s. One of the add in’s is made from a mixture of striped stems, which is tobacco dust swept from the factory’s floors. This mixture is then “beat up” like a tea bag, to form a solution called, the mother liquor. The mother liquor is a water based system, which allows the factory to add most of the chemicals, like diammonium phosphate and urea. Then the solution is laid on paper also known as recon. Recon will allow the absorption of nicotine in the body, and will equal 30% of the cigarettes content. When the smoker absorbs the nicotine it creates a free base nicotine, free base nicotine is similar

Health impact is not only on cigarette smokers but also the ones next to them. “Secondhand smoke is composed of side stream smoke (the smoke released from the burning end of a cigarette) and exhaled mainstream smoke (the smoke exhaled by the smoker)” (Hong Kong Council on Smoking and Health, 2010). Report shows that the health impact on second-hand smokers is even greater than that on the smoker. (Schick, S., & Glantz, S., 2005) Third-hand smoke is the tobacco smoke that attached to clothing, wall, furniture, hair, skin and other materials after the cigarette is extinguished. So,

Despite the extensive adverse publicity, the usage of tobacco continues in approximately 25% of all pregnancies in the United States. (Slotkin, 1988). High dosages of nicotine in fetus through maternal infusions cause harm in the nervous system development of the fetus and lessen sustainability and growth. As a result, heavy pregnant smokers were more likely to have a premature delivery. The nicotine tightens the uterine blood vessels and causes a decline of the blood flow on the uterine. Therefore, the supply of oxygen and nutrients available to the embryo decrease rapidly. This compromises cell growth and may have an incompatible effect on the mental development of the offspring. Moreover, prenatal nicotine exposure not only resulted in a

     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

It has been told that second hand smoke is more dangerous than actually inhaling the tobacco. So those who are constantly around those who smoke are at the same risk of forming illnesses and disease. It has been proven that second hand smoke has 4000 chemical compounds and 200 which are poisonous. Second hand smoke can affect any race, gender, and age. The smoker could possibly be the cause of another person’s

There are many dangerous side effects of smoking such as cancer, lung disease, heart failure and much more. There are also some minor effects such as yellow teeth, nicotine stains on fingers, bad breath and your home and body can constantly smell of smoke. Smoking is not only a danger to you but can be to others as well through passive smoking. Inhaling other peoples smoke can cause dizziness, eye irritation, headaches, coughing, nausea and sore throat. It also increases the risk of cot deaths and if a pregnant woman smokes it can affect the baby's development.
