For science to revolutionize our understanding of drug addiction and change our ideas that dates back to the 1930’s is a powerful idea that we have come to grasp. I think it was vital that scientists started to study addictive behavior because we should be focusing on preventing this disease and treating it instead of having such an emphases to punish them. For example, a woman sells her body for a heroin addiction. She gets punished but, in that punishment where is her treatment for her addiction? She will be going through withdrawals till she stands trial and in severe cases of withdrawals people have died. The brain is the most interesting yet complex organ in our body. It regulates our body’s basic functions form interpreting and responding to our experiences, shapes our thoughts, behavior and emotions. What is scary is that even though our brain sits at the center of all our human activity drugs can alter important brain areas that are crucial to life-sustaining functions. Drugs affect our brain by acting as a copy receptor that allows the drugs to attach onto and activate the neurons. The chemicals tap into our communication system and interrupts with the way our neurons ordinarily send, receive, …show more content…
They produce and target our brain’s reward system by flooding the circuit with dopamine. Dopamine works regions of our brain that regulates our movement, emotion, motivation and feelings of pleasure. At normal levels it rewards our natural behaviors. By adding drugs into our system that overstimulates the dopamine, it produces euphoric effects. Once a user feels those euphoric effects it reinforces the behavior of drug use that overtime teaches the user to repeat it. What I found most interesting is that are brains are wired to make sure that we will repeat activities that are associated with pleasure or reward. Which is why it makes sense we only remember the good memories because our brain notes when something important is
Although most public information on drugs is funded by anti-drug organizations, hopefully we will still learn the true facts about marijuana. The brain is the most complicated part of the human body. I will begin by explaining certain parts and their functions. In doing this I hope to give a better understanding of our brain while implicating the possibilities of chemical induced complications “The brain with its 15 billion neurons and nerve cells operates using chemical and electrical messages” (Swanson, 1975).1 This is how we perceive our senses. Differences in the way our brain translates these messages can impair perception.
For the purposes of this essay, I am forced to agree that drug addiction is a choice. People get high and drink because they want to and if they are not careful they can become an addict. The research I found on this particular topic seemed to have the most support and facts to dismiss the idea that addiction is a disease. I also beeivle if there was enough evidence to support the idea of addiction being a disease it would not be such a controversial topic.
There are many biological factors that are involved with the addicted brain. "The addicted brain is distinctly different from the nonaddicted brain, as manifested by changes in brain metabolic activity, receptor availability, gene expression, and responsiveness to environmental cues." (2) In the brain, there are many changes that take place when drugs enter a person's blood stream. The pathway in the brain that the drugs take is first to the ventral tegmentum to the nucleus accumbens, and the drugs also go to the limbic system and the orbitofrontal cortex, which is called the mesolimbic reward system. The activation of this reward system seems to be the common element in what hooks drug users on drugs (2).
The most commonly abused substances are Nicotine, Inhalants, Alcohol, Cocaine, Amphetamines, Prescription medications, Heroin, Ecstasy and Marijuana. 1a(National Institute on Drug Abuse, 2011) Initially, a person may find themselves using substances voluntarily and with confidence that they will be able to dictate their personal use. However, over the period of time that drug use is repeated, changes are taking place throughout the brain, whether it is functionally or structurally. Drugs contain chemicals that enter the communication system of the brain and disturb the way in which nerve cells would typically send, receive, and process information. The chemicals within these drugs will cause a disruption to the communication system by either imitating the brain’s natural chemical messengers or by over-stimulating the brains “reward system” by sending mass amounts of dopamine. As an individual prolongs his or her use of these substances, they may develop an addiction.
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.
Many people dislike the term ‘addiction’ in relation to drugs or other substances, particularly as it infers that a person is powerless over their use of a particular drug or in some circumstances, a number of substances. Whilst others maintain it is this powerlessness that is the foundation of diagnosis and treatment – that treatment is not possible without recognition of addiction itself as the ‘problem’ being addressed. The professional and public perception of addiction is complicated. There are many approaches and models to explain addiction, the role of the addict, and their environment. This essay will compare and contrast two of these approaches, the medical/disease and the social model. Initially this essay will describe the origins of each model, and follow by explaining their respective strengths and weaknesses, and finish with an overview of the key differences between them. This essay will conclude by demonstrating that a holistic approach, and a cross-pollination of these models is the most successful approach to treating addicts. As is the case for all diseases, there are multiple treatment options, and as ever person is different, the results in each individual cannot be predicted.
The repeated use of drugs often causes both physical and psychological dependence, as mentioned in an article by the Funk & Wagnalls New World Encyclopedia (“Drug Dependence”). In order for an individual to truly be set free from their addiction, seeking treatment is necessary. Rehab centers are a great place with scientifically proven methods to cure those addicted to drugs. It is important to try to end drug use in our country, rather than allowing it to continue longer than it already has. While funding for rehabilitation facilities could become an issue, drug users may continue their addiction without proper treatment, and therefore those arrested for drug use should be sent to a rehabilitation center instead of prison.
Drugs affect your brain and in turn can alter your moods and behavior. Drugs are chemicals that tap into our brain’s communication system and disrupt the way nerve cells receive, send and process information. Drugs interfere with the exchange of information in the brain producing changes that promote repeated drug use. Drugs can imitate the brain’s natural chemical messengers, or they over stimulate the reward circuit of our brain.
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.
The use of marijuana in a recreational manner, can lead to memory deficit amongst those who use it long term.
Without contrast, the primary reason for drug abuse in individuals comes from the conscious state of addiction. According to Webster’s, addiction is described as “the fact or condition of being addicted to a particular substance, thing, or activity (Hacker, 2011).” Sure, human nature’s desire to conform to peer pressure might cause one to first try a certain drug, but the euphoric mental states found in drugs mentally trap many individuals into becoming dependent upon these sensations. With that being said, these sensations vary depending on the type of drug used.
There are many different types of addictive drugs. The text referred to six different categories of drugs based on their affects to the human brain, their overall tendency for abuse, how addictive they generally are, and how dangerously lethal they can be. The text defines them as psychostimulants, sedatives, and hallucinogens. The psychostimulants give an increased feeling of alertness that is often contrasted with the tranquilizing and depressive effects of the sedative-hypnotics. The hallucinogens give visual illusions and hallucinations that are accompanied by psychosis upon occasion. Although each type of drug listed is often abused and has dramatic negative effects on the brain, not all of them are truly addictive. In order to be addictive a drug must have three effects. First, it must cause the patient to voluntarily self-administer it. Second, it must cause massive spikes in dopamine. Third, it must lower the threshold for reward within the brain’s structure.
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.
The use of drugs is a controversial topic in society today. In general, addicts show a direct link between taking drugs and suffering from their effects. People abuse drugs for a wide variety of reasons. In most cases, the use of drugs will serve a type of purpose or will give some kind of reward. These reasons for use will differ with different kinds of drugs. Various reasons for using the substance can be pain relief, depression, anxiety and weariness, acceptance into a peer group, religion, and much more. Although reasons for using may vary for each individual, it is known by all that consequences of the abuse do exist. It is only further down the line when the effects of using can be seen.
Drugs are chemicals that change the way a person's body or mind works. Drugs are not good for health as they have many side effects and damage our brain, heart and other important organs. Drug is a depressant that slows down the functions of the central nervous system and makes us less aware of the events around us. I...
