Tobacco and the Brain Essay

We know this statement and we see this in advertisements, in slogans, in posters and televisions everywhere and yet smoking still the leading cause of death in America. According to Centers for Communicable diseases, 2017, smoking is still the No. 1 cause of preventable death in the United States. It kills more people than infectious disease, abuse, firearms, obesity and traffic accidents. Some people do not believe that smoking is harmful to them. Some people do not notice the harm at first and by the time they notice the effects, they are addicted to it already. That is why the Word Health Organization calls it as “gradual killer”. Lastly, according to Sherry McKee, the director of Yale Behavioral Pharmacology Lab, “Most of the smokers think that they can just quit easily at any time and nearly all believe that they won’t be long-term smokers”. These are some of the knowledge gaps in tobacco use.

This essay will consider how each of the 5 psychological perspectives explain smoking. I will cover the psychodynamic, the behaviouristic, the biological, the cognitive and the humanistic approach.

     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.

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.

It is the most common addiction throughout the world with 1.1 trillion people smoking currently, consisting about a third of the population over 15 years old. While nicotine is the addictive substance in the tobacco that causes addiction, tobacco will increase health risks of heart attack and vascular diseases. Nicotine dependency is a complex brain disease, and we need to start thinking of it as such. New ways of ingesting this substance have been created, that try to lure and appeal to demographic, particularly younger, to consume nicotine. Regardless of how many years someone has smoked, stopping at any point will valuable and improve your quality of life. Changing the public’s view on addiction is a subject of importance, so many of others can view this as a brain disease more than a personal decision. To fight this addiction, you have to rewire your behaviors in your brain and have a drive to overcome this horrific addiction. The brain can luckily keep changing and be trained to stop cravings with a multitude of different strategies. Anyone can be affected by addiction, we need start treating addicts with evidence-based practices rather than jailing them. Through more education and laws enforced, we can only hope that the number of tobacco users can decrease more and everyone can learn to live a healthier, full life without addiction and the painful diseases that derive from

Across all addictions, there is a central theory as to how such an addiction can occur. The common mechanism of all addictive substances is the activation of the brain’s “reward system”, made up of dopaminergic neurons of the midbrain and their extensions to the limbic system (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3272277/). This system is normally used in advancing evolutionary fitness promoting activity, such as sex, food, or social interactions (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3272277/). In such normal natural behaviors, the reward system activity is relatively brief and weak. However, addictive substances abuse the system’s circuitry, causing

Smoking. A controversial, mindless activity to do in our health-conscious society today. We judge the loner and their values as we walk past them, sitting outside the restaurant to have a ‘quick fag’ whilst their friends continue to enjoy one another’s company inside the safety walls of the ‘smoke-free zone’. It’s known as an addiction. Or is it a disease? A deadly addiction, perhaps? A loss of self-respect, one’s values, responsibility. A disgusting and immature habit, only conducted by those who we think lesser of. Why can’t they control themselves? What is seriously so great about the taste, the smell, the feel, of the silent and patient killer that is tobacco?

Smoking is the single highest cause of preventable death in America and puts users at significantly greater risk for disease compared to the rest of the population. Tobacco use costs the U.S. more than 289 billion dollars annually in medical expenses and lost productivity (Surgeon General, 2014). The problems associated with smoking are due in part to its addictiveness. Nicotine is the addictive substance found in tobacco and its chemical dependence is as strong as heroin, cocaine, or alcohol (CDC, 2014). Getting all smokers to quit entirely is not realistic due to nicotine’s addictive characteristics.

Addiction is like all behaviours “the business of the brain”. Addictions are compulsive physical and psychological needs from habit-forming sustenances like nicotine, alcohol, and drugs. Being occupied with or involved in such activities, leads a person who uses them again and again to become tolerant and dependent eventually experiencing withdrawal. (Molintas, 2006).

Nicotine addiction is a most common addiction faced by adults and teens in today’s society, which could gradually lead to death eventually. A tobacco product such as a cigarettes, cigars, and pipes contains nicotine and 4,000 more different chemicals that are toxic to the body and brain physically and psychologically (CDC). Teen are pressured by their peers into start using nicotine products at early age in order to fit into a society or a group where it is symbolized as “Cool kids actions” to use this product, while adult use tobacco products because they are addicted. According to CDC more than 480,000 deaths annually are tobacco related death in which person was addicted to tobacco or victim of second hand smoke.

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.

“The overstimulation of this reward system, which normally responds to natural behaviors linked to survival (eating, spending time with loved ones, etc.), produces euphoric effects in response to psychoactive drugs. This reaction sets in motion a reinforcing pattern that “teaches” people to repeat the rewarding behavior of abusing drugs ”(“Understanding Drug Abuse). Using addictive drugs floods the limbic brain with dopamine, taking it up to as much as five or ten times the normal level. A person with elevated dopamine levels now has a brain that begins to associate the substance with an outside neurochemical reward (“Your Brain on Drugs”). As a person continues to abuse drugs, the brain adapts to the overwhelming surges in dopamine by producing less dopamine or by reducing the number of dopamine receptors in the reward circuit. The result is a lessening of dopamine’s impact on the reward circuit, which reduces the abuser’s ability to enjoy the drugs, as well as the events in life that previously brought pleasure. The decrease in normal dopamine levels encourages the addict to keep abusing drugs in an attempt to bring the dopamine function back to normal, except now larger amounts of the drug are required to achieve the same dopamine high, an effect known as tolerance (“Understanding Drug Abuse ). That is what leads to the state of addiction, which leaves the person in a cycle of craving, using, withdrawal, and relapse.

Tobacco has been around for many years, and it should be stopped, but can the economy handle it. The tobacco is reaching young children, and not to mention the nonsmokers as well. The medical effects alone should convince people to stop smoking. Even if the people wanted to quit, it's hard because they are already addicted. If the health doesn't stop people from smoking the cost should because this year the tax on tobacco has gone up dramatically. So now the cost is weakening our pockets. The only ones that win in the tobacco field are the Tobacco Company, because they make all the money. If profits fall, all they have to do is advertise a little harder and profits will roll

Sometime back one of my friends who were a regular smoker claimed to feel good and motivated to do any task after he smoked. Although he later on stopping smoking he always said that smoking was the best thing that had happened in his life. I, later on, discovered that the reason behind his happy mood after taking a puff was contributed by nicotine, which triggered his brain to produce a happy feeling. Use of nicotine is said to cause several social influences. For instance, smoking plays an integral part in starting a conversation among smokers.

Cigarette smoking is something people all over the world have been doing for about 2000 years. Back in 2003, the first electronic cigarette was successfully created by a gentleman named Hon Lik. Lik was a 52 year old pharmacist at the time, whom of which was also a smoker. The inspiration behind making the electronic cigarette came after Lik’s father passed away from lung cancer due to him also being a heavy smoker. “A Historical Timeline of Electronic Cigarettes.” cassia.org. Consumer Advocates for Smoke Free Alternatives Association, 15 June 2017. The idea behind creating this device was to give smokers a way to still ingest nicotine, the most addictive chemical in tobacco cigarettes, without the countless negative health effects that
