Perhaps One's Actions are Not Theirs After All Perhaps those addicted may not be solely at fault. There are many types of addictions but they all have one common attribute. The one attribute they all have in common is that they all stem from the brain. There is a common belief that addictions result from one making poor choices; however, that might not always be the case. By understanding addictions and how they can be hereditary is crucial in order to prevent addictions for the duration of generations. The importance of understanding that genetics are linked to addition is significant because it can prevent future addictions throughout families. Most people in today’s world use the word addiction but they do not fully understand the meaning …show more content…
The addict’s brain becomes overridden and continuously wants the substance which it craves. Help Guide.org produced an article titled “Understanding Addiction”. The article reads as following, “Addictive substances and behaviors stimulate the circuit then overload it. In nature rewards usually come only with time and effort. Addictive drugs and behaviors provide a shortcut, flooding the brain with dopamine and other neurotransmitters”(Understanding Addiction 1). In other words, when the brain is pleasured it feels rewarded. Normally rewards are earned, but the use of substances provides a rewarded feeling to the brain. Neurobiology is the biology of the nervous system.This research is what provides us with the information on the brain being taken over. The brain is broken up into several sections. Research has shown there to be certain genetic codes that vary from addiction to addiction. These codes can inform people what the brain’s drug of choice may or may not be. No one certain factor can determine if a person becomes addicted or not. For example, the AI allele of the dopamine receptor gene DRDR is mainly found in those addicted to alcohol or cocaine. Another example is that those with high stress level hormones have been noted to have an increased risk for addition. Individual differences have also shown to meter the effectiveness of a drug on a person. One study compared two sons, one of the son’s father's was a alcoholic and the other son’s father was not. Neither son drinks, but when given alcohol the son of the alcoholic seemed to have a higher tolerability to the alcohol than the son of the non alcoholic father. Obviously the son of the alcoholic has genes from his father that cause alcohol not to affect him as much, and this can lead to him over drinking and becoming an alcoholic
Brain chemistry can affect different addicts more then others. Drugs and alcohol are more of the main addictions that brain chemistry affects. Once taking these addictive substances your internal natural drug dopamine is lowers causing you to seek more external addictive substances. This causes craving and makes it a lot harder for the addict to stop. In Olds and Milner’s later experiments, they allowed the rats to press a particular lever to arouse themselves, to the effect that they would press it as much as seven-hundred times per hour. This region soon came to be known as the "pleasure center". Using drugs and alcohol stimulates the pleasure center in the brain that makes your brain think, “feels good- want more“. This can make it increasingly harder for an addict to stop using, until they hit a point called “rock bottom”. This is where choice comes back into play.
The meaning of a word portrays what it encompasses and if the phrase itself is misunderstood then defining what it’s trying to explain can be a studious task. Addiction has been defined by many and holds different meanings based on the context it’s used in. Addiction can be defined as a condition in which a person undertakes the use of substance, or engages in activities, which in turn brings pleasure, and tends to divert oneself from their day-to-day duties and responsibilities. Addiction is mostly related to drug use but it is also used to describe non-drug entities, such as gambling, and Internet addictions (Avena et al, 2008). Researchers (Herbert, J. D., Forman, E. M., 2010) have been keen on identifying the factors that lead to
Addiction is thought of a biological nature that is past through genetics according to the biological theory as explained in P2. A contrasting theory of the biological theory would be the classical and operant conditioning theory, this was made by Pavlov. The basis of conditioning theories is that addiction is the end result of the reinforcement of drug use. The drug acts as a reinforcer and gains control over the user’s behavior. In contrast to the biological models of the exposure theories, these conditioning models suggest that anyone can show addictive behavior if they are given reinforcements, regardless of their genetics. The advantage of this
The biological aspect of addiction takes into account the genetic and inherited components of addiction, as well as the effects of addiction on the body itself. It also includes the neurobiological and neurobehavioral theories and studies, which are becoming the most popular ways in studying addiction. The physical component of addiction primarily relies on the dependence of the substance, the tolerance that the body creates as a result, and the experience of withdrawal symptoms. The psychological
“The statistical associations between genetic factors and alcohol abuse are very strong” (McNeece & DiNitto, 2012). However, there is still much debate over the validity of genetics as a definite cause for addiction. Perhaps, the reason for this is because the number of children of alcoholics that go on to become alcoholics is still small. Additionally, genetic predisposition cannot explain the number of cases of alcoholics that did not come from alcoholic parents or families. In fact, addiction can be so prominent, that it remains even after the drug use has ended (McNeece & DiNitto, 2012). Therefore, the biological theory should not be ruled as it is based on what takes place in the body. There is no other theory that can explain how a person could still have addiction symptoms when the substance is absent from their system. Predisposition implies that there is a mutation or malfunction in the body that appears to cause a craving or susceptibility to becoming addicted to a substance.
To begin with, studies have found that inherited genes are responsible for a considerably large part of the probability that someone will become addicted to any kind of substance or behavior. Addiction is strongly influenced by genetic factors in the later stages of addiction, such as problem use and dependence of an addictive substance. Some genetic factors can make an individual more likely to become addicted to only one specific drug. On the other hand, some genes can make an individual more likely to become addicted in general. Some individuals might be genetically inclined to risk-taking behavior such as receiving large jolts of dopamine through what they consider to be the “excitement” of drug use. These individuals could be subject to keep returning to the illicit and harmful drugs that they find enjoyable despite what they know of the harmful effects. These genetic influences could make them more likely to become addicted to alcohol, cocaine, tobacco, gambling, or any number of substances or activities. Addiction has an inherited component and it
Genetic factors have been directly linked to the risk of an individual’s vulnerability to addiction (APA, 2008). In addition, other risk factors that play a
The National Institute on Drug Abuse (NIDA) describes addiction as a, “chronic disease characterized by drug seeking and use that is compulsive, or difficult to control, despite harmful consequences” (“Understanding Drug Use and Addiction,” 2016). Long-term use can effect and change a person’s ability to learn, judge, and make decisions. Stress, memory issues, and behavior problems are also common side effects of extended drug use. There is not one single factor that can determine if a person will become addicted drugs. However, certain risk factors have been identified as predicting higher probabilities of addiction because of a person’s biology, environment, and development. Adolescents who abuse
Genes and environment both prove to be important when determining who will be susceptible to becoming addicted to substances and who will not (Durand, Barlow, 2016, 388-389). Using drugs is based on environmental factors but becoming dependent on drugs will occur if a person is genetically vulnerable. There is no specific gene that can be held responsible for this phenomenon, but rather a group of genes that put one at risk for substance use disorder broadly. Susceptibility to addiction to one substance in particular does not occur. Psychological factors must also be considered when discussing what causes substance abuse disorder. Positive reinforcement (making one feel good) and negative reinforcement (making one feel less bad) are two primary reasons for continuing drug use.
At the end of the course, it would only make sense that we turn to the question that we considered at the beginning of the course: What is addiction? Although the many decades of research on the topic have focused on many of the same topics, there are still disagreements on the answer to this question. Despite differences in opinion related to some of the most basics aspects in the field, there have been improvements in treatment and the way the topic is discussed. When I began this course, I was firmly ground in the belief that addiction is a disease, but there were some different parts of the course that have encouraged me to reexamine my initial understanding of addiction. This final paper will detail the process in which my beliefs at the
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
According to Leshner (1998) at its core, addiction is actually a brain disease. There are many factors that come into consideration with addiction which are specific to each individual such as their physiological state, his or her genetics, environmental and societal situation, and how he or she is embedded into society comes together in the end. Some of these contributing factors can be controlled or modified in order to treat an addiction, while other cannot be modified such as genetics and some psychological states. These two key factors are those that researchers in both the medical and psychology fields have studied, to determine better treatment options as they can present a barrier in creating effective addiction management
The SciShow video "The Chemistry of Addiction" was very informative and insightful. There was a lot of information that was new to me. I learned that our brains produce at least 100 different neurotransmitters - chemical messengers that pass signals from to a neuron or a cell it wants to activate. I've also learned that addictive drugs mess with our dopamine levels and abuse the brain's ability to recognize unnatural highs. After using a drug over a long period of time, our brains will start to lower the amount of neurotransmitters to try to balance the drug's effects. I learned that addictive drugs mess with your brain in two major main ways. They copy your natural neurotransmitter and the other artificially change your levels
It remains controversial whether or not we should reduce addiction to a "chronic disease of the brain. However there is strong data that states a genetic component to addiction. Don’t get confused, addiction does not only develop because someone is weak-willed. Addicted persons do not choose their genetics. Therefore, they do not control whether they are at risk for developing an
According to Rozzano” If you’re genetically predisposed to this illness (meaning addiction runs in your family), scientists say your brain chemistry will change upon introduction” (Rozzano). He believes that once a person with family history addiction starts using drugs the person loses the power of control of their behavior. I understand the addict has no choice, and his behavior is resistant to long-term change.Symptoms of addiction include a person's inability to stop using the substance, devoting a lot of time and effort toward obtaining, using, and recovering from the substance’s effects, discontinuing important social, employment, and recreational activities due to preoccupation with the substance, developing tolerance for the substance, and developing withdrawal symptoms. I believe environment and genetics seem to be the main causes is an addiction. I call this Nature or Nurture. When a person has been conditioned to drugs and alcohol due to them being raised in an environment where this is all they see as a child, this could be the condition that they are used to that encourages them to try drugs. Also, it depends on what kind of drugs a person is a choice to try; I believe the nature of an addiction depends on what you're addicted to. I will try to use the drugs my father used as an example since I know a lot more information on this particular drugs than others. Alcohol, for example, is chemically addictive. If an alcoholic is not able to get their fix, they tremor, lose their appetite, maybe even hallucinate or go through other withdrawal symptoms. Marijuana on the other is not chemically addictive. Those who are addicted to it are psychologically addicted to its effect on their thoughts and moods. If they were to quit, they might become more irritable or have to adjust their mood to sobriety, but they won't go through withdrawal symptom like those associated with
