Addiction
Many people have been a witness to some kind of addiction. Addiction comes in many shapes and forms. For example, someone can be addicted to can be drugs, alcohol, sex, technology, cigarettes etc. The brain is one of the main components that plays an enormous part in addiction. Since the day I entered this world, I have experienced addiction. I have not experienced personally, but I have had the rare opportunity to observe addiction. People who suffer from this weakness cannot be grouped in a whole. Addiction does not affect a certain demographic; people from all walks of life are at risk and the addiction does so much more than get them high. To be able to understand addiction at its basic level, take a look at the brain and how addiction captures it. When understanding addiction and the brain, think of it along the lines of a

For example, if someone is driven by being a risk taker or novelty seeker they may not necessarily respond to the same methods that work for people who suffer from traumatic stress or hypersensitivity to everyday stress (“The Addicted Brain”). The brain learns addiction and stores it as a memory, it is a long journey which can be slow and hesitant process; in which hopefully the influence of those memories minimizes (“How addiction hijacks the brain”). New findings of the brain and the addiction have opened up new opportunities for treatment options, but process is still a classic rabbit and turtle race. One avenue that has been looked into is a dopamine receptor antagonists, drugs that attach themselves to the receptors for dopamine and prevent drug seeking behavior (“The Addicted Brain”). Unfortunately this treatment has yielded problems with the side effects that it causes. The problems that follow are the substances that bind to the dopamine receptors not only block addiction, but also block natural rewards as well (“The Addicted
Addiction may be defined as the chronic use of drugs alongside the problems resulting from their use. Despite the person being aware of the consequences of using the drug, he continues to use it. If not attended to, addiction may cause serious social problems and even death (Hanson et al. 36). In order to address drug addiction, it is vital to understand addiction itself and where it stems from.
Sally Satel, author of “Addiction Doesn’t Discriminate? Wrong,” leads us down a harrowing path of the causes and effects that lead people to addiction. It can be a choice, possibly subconscious, or a condition that leads a person left fighting a lifelong battle they did not intend to sign up for. Mental and emotional health/conditions, personality traits, attitudes, values, behaviors, choices, and perceived rewards are just a few of the supposed causes of becoming an addict.

There are many different definitions in which people provide regarding addiction. May (1988) describes that addiction “is a state of compulsion, obsession, or preoccupation that enslaves a person’s will and desire” (p. 14). Individuals who suffer from addiction provide their time and energy toward other things that are not healthy and safe. The book
Drugs seem to cause surges in dopamine neurotransmitters and other pleasure brain messengers. However, the brain quickly adapts and these circuits desensitize, which allows for withdrawal symptoms to occur (3). Drug addiction works on some of the same neurobiological mechanisms that aid in learning and memories (3). "This new view of dopamine as an aid to learning rather than a pleasure mediator may help explain why many addictive drugs, which unleash massive surges of the neurotransmitter in the brain, can drive continued use without producing pleasure-as when cocaine addicts continue to take hits long after the euphoric effects of the drug have worn off or when smokers smoke after cigarettes become distasteful." (4)
Addiction is defined as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, according to the National Institute on Drug Abuse. Addiction is normally thought of as drug abuse and alcoholism but people can also be addicted to things such as gambling and sex as well. The controversy on if addiction is a disease or a choice is a continuous debate. Everyone has an opinion on this topic, one side believes it’s a disease, while the other believes it is a choice. Although addiction has been assumed to be a lack of willpower and a weakness, addiction is actually a complex disease that changes the wiring of the brain. Addiction is a brain disease expressed in the form of compulsive behavior (Leshner.) Both devolping
Drug addiction is often characterized as being a complex brain disease that causes compulsive, uncontrollable, drug craving, seeking and use without any regards to the consequences they may bring upon themselves, or society. As long as the brain is exposed to these large amounts of dopamine on the reward system, it will inevitably develop a tolerance to the current dopamine levels, which it is receiving, lessening the pleasure the user will experience. In order to satisfy the brains “reward...
According to Leshner, drug addiction is a chronic brain disease that is expressed in the form of compulsive behaviors (Leshner, 2001). He believes that drug addiction is influence by both biological, and behavioral factors, and to solve this addiction problem we need to focus on these same factors. On the other hand, Neil Levy argues that addiction is not a brain disease rather it is a behavioral disorder embedded in social context (Levy, 2013). I believe, drug addiction is a recurring brain disease that can be healed when we alter and eliminate all the factors that are reinforcing drug addiction.
Any comprehensive theory (model) of substance abuse has to answer several difficult questions: What environmental and social factors in an individual’s life cause them to start abusing a drug? What factors cause them to continue? What physiological mechanisms make a drug rewarding? What is addiction, behaviorally and physiologically, and why is it so hard to quit? These questions can be answered in the major theories (models) that are described below using an integrative approach that addresses the problem of substance abuse and addiction as an urgent but elusive goal (Kauffman & Poulin, 1996).
Main Point: What defines an addiction? According to Psychology Today, “Addiction is a condition that results when a person ingests a substance…. or engages in an activity….that can be pleasurable but the continued use/act of which becomes compulsive and interferes with ordinary life responsibilities, such as work, relationships, or health.” This can range anywhere from drug use to eating disorders, to gambling, to even texting in today’s generation. Shocking to say the least, especially when most people do not even know they are addicted or are an addict until they realize this definition.
Drug abuse and addiction are issues that affect people everywhere. However, these issues are usually treated as criminal activity rather than issues of public health. There is a conflict over whether addiction related to drug abuse is a disease or a choice. Addiction as a choice suggests that drug abusers are completely responsible for their actions, while addiction as a disease suggests that drug abusers need help in order to break their cycle of addiction. There is a lot of evidence that suggests that addiction is a disease, and should be treated rather than punished. Drug addiction is a disease because: some people are more likely to suffer from addiction due to their genes, drug abuse brought on by addictive behavior changes the brain and worsens the addiction, and the environment a person lives in can cause the person to relapse because addiction can so strongly affect a person.
So, it is clear that addiction is all around us and can attack anyone of us at any given time. Even studies conducted show that people neglect to speak around their dependency for two primary reasons. Foremost, because people do not comprehend, or they bear a total misconception to their addiction, that they do not realize that addictions can be critical to their overall wellness. Moreover, second, many people believe being an addict will never happen to them, but, in reality, most addictions start off as simple little habits. Such as starting with one drink after dinner and before you know it you are drinking several drinks a day. However, one does not opt to be addicted to a substance, because addictions are physical defects in the brain, a disease, and not one’s choice.
The biology of addiction helps us understand why people consume drugs and their effects on the brain and other parts of the body. When some people think of addiction, alcohol comes to their mind. Nevertheless, there are other things that people can get
Humans are environmentally and genetically predisposed to developing a motivated addictive behavior. Addiction is a brain disease and a behavior. All behaviors are choices. Choices that adolescences make at a young age directly affect the outcomes of their futures. Many factors contribute to an adolescence becoming an addict or exhibiting a drug seeking behavior. Nearly all drugs of abuse increase dopamine release. Dopamine is an important neurotransmitter in drug abuse and addiction. Dopamine plays a role in reward motivated behaviors, motor control and important hormones. It’s known as the “feel good hormone” which is why people abuse drugs that increase the release of dopamine. Since life is unpredictable, our brains have evolved the ability to remodel themselves in response to our experiences. The more we practice an activity the more neurons developed in order to fine-tune that activity causing addictive behaviors to be detrimental.
Drug addiction is a very big problem in today’s society. Many people have had their lives ruined due to drug addiction. The people that use the drugs don’t even realize that they have an addiction. They continue to use the drug not even realizing that their whole world is crashing down around them. Drug addicts normally lose their family and friends due to drug addiction.
