Due to the 25 years of smoking Max has damaged his lungs, seen in the chest x-ray, which allowed several pathogens to damage his lungs further. This resulted in pulmonary fibrosis, a scaring of the lung tissue. The scared tissue decreases gas exchange in the lungs causing a buildup of carbonic acid resulting in uncompensated acidosis.…
An Australian Health Survey conducted in 2011-2012 concluded that 3.1 million Australians are current smokers. (Australian Bureau of Statistics, 2013). This means that 14% of Australia’s population are current smokers compared to more than 40% in the 1980’s – a dramatic decrease with the smoking rate continuing to decline each year. Now there are many factors that can be considered for this drop such as the rise in prices or maybe less accessibility but another big factor is that it’s no longer seen in the same way socially like it was back in the 1980’s. With more and more anti-smoking products being created it decreases the amount of smokers and I’m…
The literary story “The Smoker” is told in third person through the Doughlas Kerchek, a teacher of high school English. He teaches English at St Agnes High School which is an all girl private school. In this story it goes into detail about the character, Douglas, how he has a PH.D in English that he got from Harvard and how he lives this simple life alone. A solitary well –boxer- built man, good –looking early 30’s, he is a figure of interest among the young women and his collegues. The title refers to the recurring event of the Friday Night Smokers hosted by the Society of gentlemens club in Kerchek hometown in which Mr Kerchek went to often. He lived this simple life where he had a routine he did, and he did this day by day week by week.…
Pathologically, addiction is characterized by the pursuit of reward or relief substances in a compulsive, uncontrolled, and debilitating fashion. This behavior occurs as a result of alterations in the mesolimbic pathway of the brain, implicated in reward, motivation, and memory. More specifically, the ventral tegmental area (VTA) and nucleus accumbens are two regions that directly mediate addiction. The VTA, activated by addictive substances, is the site of dopaminergic neurons that project onto the nucleus accumbens in the ventral striatum (Adinoff, 2004). Therefore, studies on addiction usually center around these regions to explore the genetic and neurobiological basis underlying this chronic brain disease. One of the most prominent and…

The brain has several dopamine pathways with different functions. The drugs that block dopamine synapses produce their benefits by acting on neurons in the DA. This system is a set of neurons that project from the midbrain tegmentum to the limbic system (Kalat, 1998). This neurotransmitter system in the brain is where most drugs abuse their reinforcing effects that cause addiction (Phllips et al., 2003). Control of this system, by the amygdala, can influence the incentive value of the sensory property of food and its modulation by the drive-state of the animal (Phillips at al., 2003). When nicotine is constantly producing more dopamine for these areas of the brain, the brain becomes conditioned to this effect and the process becomes a normal process, when in actuality it is unnatural. A study was conducted on the levels of dopamine within the basal ganglia of the human brain, where nine smokers and ten non-smokers were the subjects. The study revealed that striatal dopamine activity proved to be significantly higher in smokers than non-smokers (Raimo et al., 2000). This shows that cigarette smoking is related to increased dopaminergic activity in the human basil ganglia (Salokangas, 2000). This study proves that the amount of dopamine within the brain of smokers is unnatural compared to the dopamine levels within the brain of non-smokers. When tobacco users…
Nicotine is an addictive drug which basically means that the use of nicotine causes reactions in the brain that makes the person want to use more and more of the drug or substance. Addictive drugs cause withdrawal symptoms that can be unpleasant. Breaking an addiction can be very unpleasant and difficult due to the fact that the person breaking the addiction has to go through withdrawals. Nicotine is historically one of the most difficult addictions to break due to the withdrawal symptoms.…
The history of addiction goes back centuries, and unfortunately, there is still a long way to go for people to realize the effects of chemical substances do more harm than good. The difference between drug use and abuse relies heavily on a person’s dependence on the substance. The line between the differences is often very fine. Depending on other factors involved, such as morals, values, environment, and genetic predisposition, the line will most likely be crossed without regard to the consequences until treatment and recovery are the only options left. This is essay compares two theoretical explanations for addiction, including a psychological theory, and a biological theory. In addition, the writer will describe the viewpoints of each model, and how their effectiveness in addiction prevention and intervention.…
It has an important part in regulating mood and pleasure, both serving as a trigger for the synthesis of adrenaline and noradrenaline and acting as a neurotransmitter. When nicotine goes to the brain, it produces a rush of dopamine into the bloodstream, causing the user to become more relaxed and calm. In this respect, nicotine's chemical action is very similar to such other drugs as cocaine, amphetamines ,and morphine. In effect, each time a smokeless tobacco user puts a pinch of tobacco in his or her mouth or inhales some powder, he or she gets a powerfully reinforcing and rewarding chemical message from the brain that, over a short period of time, will cause physical and emotional dependence on tobacco. However, because the body quickly becomes used to nicotine through a process called "tolerance," users experience a gradual rise in the amount of tobacco they need to get the same physiological…
But defining addiction is just one step. To actually understand addiction we must know what causes it and what happens internally during it. To many, addiction to drugs, gambling, and other activities may seem like a choice; however, addiction isn’t the addict’s choice. Only the initial indulgence in the activity is. What takes place after the drugs are consumed or that first game of poker takes place is completely neurological. In fact, addiction is a disease. When a heroin addict takes a hit, it stimulates the neurotransmitter system of his brain, producing dopamine and activating the feeling of pleasure he gets. This physical change that takes place in the body at this time is what classifies addiction as a disease. Addiction not only produces a large amount of dopamine, but the greatest change in the body is the rewiring of the brain. The long-lasting, rewiring changes to the brain are “electrical, morphological, and biochemical functions of the neurons…
Nicotine stimulates the dopaminergic transmission of VTA in the midbrain, which activates the nucleus acumens, which is an area crucial for nicotine-mediated physiological effects such as addiction, reward, and pleasure. Nicotine also facilitates the release of glutamate from the amygdala. Through time the GABA-ergic response decreases, the dopaminergic response is heightened, and the addictive effects of nicotine potentiate (Rosenthal, D. G et al.…
With all this information like, oral cancer being caused by smoking and there being more cases of death from smoking that smokeless tobacco. This proves that if you are smoker save your life and change to smokeless tobacco or just stop.…
In the 1990’s, however following the new advances in neuroimaging, some of the biological mechanisms of addiction became apparent and some scientists conceptualized addiction as a disease of biological, rather than purely mental origins. For example, in his capacity as the director of the National Institute on Drug Abuse, Alan Leshner wrote that the reason we ought to think of addiction as a disease is that it ‘is tied to changes in brain structure and…
The brain disease model of addiction (BDMA) is an approach that describes an addiction as a chronic relapsing brain disease with biological, neurological, genetic, and environmental sources of origin (Leshner, 1997). This new definition of addiction was proposed through discovery of evidence that the brain drastically changes through repeated use of addictive substances (in terms of this essay, drugs), such as altering the brain's mesolimbic pathway through constant release of dopamine (CITATION HERE), thus changing the individual’s motivational system and leading to compulsive drug use. Due to how recent the definition was posited, there has been little empirical evidence regarding new treatments, but many possible treatments have been proposed,…
